Troubleshooting app crashes on Android


Applications and games

Please note that each mobile phone is sold with the most current operating system at that time, which most closely matches the current characteristics of the smartphone.

Yes, some manufacturers do make regular updates for their gadgets, but not all of them, and support usually lasts no more than two years for budget models.

Even if you received updates, it is not a fact that the phone will work as fast as when you bought it.

This issue affects games and applications. Developers release updates optimized for new devices. At the same time, on older models the game may also become unstable.

There are two options to solve this problem:

  • you just need to make a choice between application speed and functionality. If your smartphone is not a flagship or very powerful, we strongly advise you not to update many applications. The functionality will not be the same as after the update, but the speed will remain the same;
  • It would also be a good option to install upgraded, lightweight firmware. Although this is a little, it will increase the speed of operation of both the system in general and individual software.

Updated apps slow down Android

Android application developers primarily focus on new models of gadgets. Application programmers optimize their creations for today's device capabilities. But with each successive application update, the phone begins to work slower, and its system resources are used more intensively.

For the majority of developers, it is simply not profitable to please users of old hardware. The current Chrome browser already needs hundreds of free megabytes of Android memory, which was unthinkable 5-7 years ago. But cache data and other files also accumulate that require additional space in the device’s far from unlimited memory.

Users can prevent heavyweight applications from updating. Often, older versions of cumbersome programs will still be able to work normally for a while. But in the case of the same browser or, say, a GPS navigator, such a decision will be unjustified.

Useful and popular sites are becoming more complex and larger, and maps of the area are changing regularly. Progress, like the flow of events in general, cannot be stopped. Life itself makes adjustments and forces programmers to complicate software.

But not everything is so bad for those who are content with outdated gadgets. For example, Skype, Facebook, Opera are supplemented with Lite versions. Lite, in Russian “light” means “light”. This is a lightweight version of the application. It requires less Android resources compared to common “heavy” versions.

Messengers like Telegram, WhatsApp, Viber are relatively “easy” in themselves. This minimal set of “light” applications will allow you to fully maintain contact with other people and obtain the necessary information on the Internet on an old Android.

Background applications

The presence of many applications running in the background is the most common reason why Android starts to slow down. If you hide many applications in the background, then you can’t count on stable operation of your Android device, since the system will spend a lot of resources on maintaining the functionality of these applications.

The solution to the problem is very simple. You just need to delete applications running in the background, or at least disable them in the phone settings.

Another interesting thing is that starting with Android 4.1, the system is able to independently distribute resources to applications, as well as close programs running in the background.

By the way, you can set a limit on background processes yourself, but only if your phone’s Android version is 4.1 and higher. How to do it? It's simple .

Follow these steps:

  1. go to the device settings;
  2. select “For Developers”;
  3. find the line “Background process limit”;

  4. specify the number of processes you need.

I would also like to note the fact that there are no viruses for the Android operating system, therefore there is no need for an antivirus. It will simply eat up RAM in the background, without bringing any benefit.

There is little memory space left on the phone

Android needs to always have a large supply of free memory on the smartphone. Once you fill the memory to capacity, for example, by 70-80%, the smartphone will begin to slow down.

In general, it is advisable to leave as much free memory on your smartphone as possible. Then the device will work noticeably faster.

So it is advisable to install and store most programs, applications and media files on an additional SD memory card, if available and supported by Android. Let the additional memory be loaded to the maximum, it does not affect the reduction in Android speed. But in this case, the main memory of the device will be free, which is the key to high operating speed.


Rice. 1. The “To SD memory card” option is available for the Instagram application on Android.

By clicking on the “To SD memory card” option, you can move the Instagram application on Android from the main memory to SD. After moving, instead of the “To SD memory card” option, another one will appear - “Move to device memory” (Fig. 2).


Rice. 2. The “To SD memory card” option has changed to the “Move to device memory” option.

As can be seen from the numbers shown in Fig. 1 and fig. 2, the Instagram application was not completely moved, but only partially. It depends on the application itself, as well as on the Android version and on their interaction with each other.

Removing unnecessary applications and transferring personal files

There is no need to accumulate unnecessary applications on your smartphone and everything that additionally loads it. Personal files such as photos, videos, archives, chats, etc. should be periodically uploaded, for example, to the clouds or to a computer or laptop. You can then transfer files from your computer to flash drives, external hard drives, and similar external storage devices.

Cache files also take up memory. But even regularly clearing the cache doesn't help much. Almost instantly the cache restores its size again. This does not mean that there is no need to clear the cache; the procedure is useful. But, as a rule, this briefly increases the speed of the device.

Smartphones without support for SD memory cards often have impressive amounts of native memory. But even a large memory can become full at some point.

You still need to clean the device's memory from time to time. True, this helps for a short time because the user will take new photos, videos, the cache will grow, background processes will not disappear, new Android updates will arrive, and so on.

Widgets

Smartphone manufacturers do not recommend crowding your smartphone desktop with various kinds of widgets, since each of them requires resources to operate. If you use everything on your phone, its performance will slow down significantly, especially if you play demanding games.

When deleting most of the widgets, desktops are freed up; if possible, it is better to delete them.

How to diagnose Huawei and Honor phones at home

What to do if your phone doesn't work well ? This is the second most popular question that my friends ask me. Ahead of him is only “ which phone is better to buy?” " Usually I roughly understand what causes it. People simply don't understand what to complain about because, as a rule, the problem does not come alone. Interface lags, application crashes, rapid battery drain and interruptions in the wireless connection, regardless of its type. All this can appear at once, and the average user has no way of understanding what’s going on. At least that's what they think.

You can diagnose your smartphone at home

New Huawei phones will get smart eye control and other features

I don’t know about others, but Huawei integrates a special tool into all its smartphones, the name of which speaks for itself - “Diagnostics”. It, as you might guess, allows you to scan the device for existing deficiencies and, if any, notify the user about it. In addition to the actual notifications about the presence of problems, “Diagnostics” can suggest ways to solve them, and, as practice shows, most of them can actually be solved at home.

Cluttered system

By the way, perhaps Android is slowing down due to the fact that the file system is heavily clogged with unnecessary files. This is inevitable, and the longer the system is not cleaned, the more dirty the system becomes, the more glitchy the phone becomes.

What files are clogging the system? There are many of them, namely:

  • software operation logs;
  • unfinished processes;
  • old and unnecessary cookies;
  • download history;
  • browser search history;
  • application and game caches;
  • calls and SMS messages.

Most of all, cache files clutter up memory. They are stored both on the memory card and in the internal memory of the phone. They are needed in order to save traffic and load pages that require Internet access faster.

The files seem to be useful, but they still need to be cleaned. How to do it? There are several options. The best way is to download a special application from Google Play.

Here are the best:

  1. Cleen Mater. This is the most famous smartphone cleaning application. This software is also used as a task manager, manager of running processes and applications. When cleaning, the utility removes everything unnecessary, including temporary program files, CACHE files, files on the clipboard, browser search history, and cookie files. Clean Master is able to clean not only internal and external drives, but also RAM. The program is free and free to download.

  2. 1-Click Cleaner. The program, like the previous one, is completely free, and the name speaks for itself. With just one tap on the screen you will get rid of all unnecessary files. It is possible to display a shortcut on the desktop and clean your smartphone without even going into the software interface.

How to check your phone speed

Before you improve the performance of your Honor 8X or other device, you need to be sure that it is running slowly. In addition, after completing all the manipulations, you need to make sure that it brought results. Whether or not you succeeded in speeding up your smartphone can be done visually, but it’s not entirely convenient. It is better to use special applications. Optimal solutions:

Knowing how to speed up Honor 7a, you can improve its performance and achieve the desired performance. In the comments, share what methods you use to achieve results.

Lack of free space

If the phone slows down very much, then the reason may be a lack of free space. The phone's built-in storage is designed in such a way that if it is filled to capacity, the phone can start to become very glitchy.

If the internal memory of the device is full, then you need to clear it, at least 30% should be free.

For this we recommend:

  • transfer all data to a memory card;
  • transfer applications to a memory card;
  • Use the above apps to clean up trash.

How to fix problems

A simple but effective way to eliminate system freezes is to disable built-in functions that take up a lot of energy and memory of the device. An example would be voice typing of the Google search string. You can opt out of this feature (which is not used very often) in the application settings options. After the procedure, it is recommended to clear the cache and restart the phone.

Lack of support for TRIM technology

TRIM technology first appeared in Andrid4.3. It allows the smartphone to operate smoothly and stably even several years after purchase. It’s a shame, of course, that it wasn’t introduced earlier.

The main reason for the slowdown over time is that almost all phones have SSD drives installed, so each cell has a very limited recording resource.

Even if you delete files, the memory controller will think until the last minute that they are there. The more times the files are rewritten, the more cells are occupied, the more the controller has to work, the slower it starts to work.

TRIM technology helps by resetting the controller data every 24 hours and forgetting what has already been deleted. The memory controller will be informed that certain data is no longer needed because it has been deleted.

It is also worth noting the fact that the TRIM function will only work on good, high-quality controllers; accordingly, the most budget models and cheap copies will not support it. This should definitely be taken into account.

If your operating system version is lower than 4.3, we recommend trying the LagFix application. There are many positive reviews about it on the Internet.

How to check a smartphone

Built-in diagnostic tool allows you to identify most existing deficiencies

The test requires active participation on your part

Here we need to make a small digression. A diagnostic test is not only a rather lengthy procedure, but also interactive. This means that during testing you will be required to perform several actions - from listening to the playback signals to check the speakers, to pressing the screen to check the quality of the touchscreen. It is very important to carry out all actions in full accordance with the instructions and honestly. Despite the fact that the smartphone has smart tools, it also focuses on the user's responses.

Android slows down after update

If you decide to update your smartphone, and after the update it starts to slow down, we recommend resetting your phone to factory settings. Most likely this action will help solve the problem. If not, then you will have to reflash your smartphone.

The matter is complicated, it is better to trust the professionals, since one wrong move, and your favorite smartphone will turn into a useless brick, unless you can sell it for parts.

As for resetting the settings, everything is simple, you need to do the following:

  1. go to your phone settings;
  2. select “Backup and reset”;
  3. then “Reset settings”;

  4. then “Reset device settings”;
  5. Click on “Erase everything”.

If you have important data on your phone, don’t forget to either reset it to another drive or make a backup copy for recovery in advance.

How to speed up Honor and improve its performance significantly

How to speed up Honor 7a, 8s, 9 Lite, 20, 9x, 10, x5, 7c or other models? Remove unnecessary applications, clean RAM, update the firmware, make the correct smartphone settings, disable unnecessary services, turn off GPS or use special programs. Below we will look at how to improve the performance of the Honor 7 s and other models, what is needed for this, and how you can check the speed of your mobile device.

Disable unused processes and services

First of all, the user needs to pay attention to the processes and services that are activated in the system by default. It is advisable to do this after purchasing the gadget and turning it on for the first time.

Don’t know how to solve a problem with your gadget and need expert advice? Alexey, a smartphone and tablet repairman at the service center, answers your questions. Write to me »

In this situation, you first need to disable the NFC module and geolocation while browsing the Internet. NFC uses quite a lot of system resources, and if you frequently surf the Internet, geolocation slows down loading files and opening pages.

It is also necessary to pay attention to the use of Wi-Fi and Bluetooth wireless communication modules. Some users sometimes do not disable these modules at all, assuming that this will not affect system performance. This is an absolute misconception, since they not only load system resources, but also drain the battery very quickly, which affects the launch of third-party applets and system performance.

Reviews in question-answer format

So, let's check out the reviews. Or rather, requests, as well as answers to them:

Anton. I have honor 10. I actively use the phone for various purposes. Naturally, and Wi-fi. And suddenly I recently read that an update arrived via Wi-Fi. And I really don’t want to install it. Now the smartphone requires a reboot. I’m not doing this yet, but I still have to. How to get rid of this update?

Answer. Install a special program on your computer called HiSuite. Next, connect your mobile phone to your PC and follow the instructions from this software.

Alina. I use Honor 9 lite. I installed the eighth version of the update. And problems immediately began. For example, the network is completely lost as soon as I start a regular telephone conversation.

Answer. It may be easier to return to the seventh version if everything worked stably before.

Boris. On my Honor 7a the screen is glitchy after the update. When the facial recognition tool is launched, it only locks in the vertical position.

Recommendation. Go to your smartphone’s settings and deactivate the “device activation” function - just move the slider next to it.

Bogdan. I have this problem now - on my Huawei P20 Lite, for some reason all updates come to the so-called lock screen. And this is very inconvenient.

Recommendations. Change the lock screen theme to something else. Most likely the reason lies precisely in this.

Vladimir. Some people write that after the update their sensor is very glitchy. If this is the case, I advise you to return to the seventh version of the firmware. Using, of course, the well-known HiSuite software. But there is an important point. With such a rollback, personal data is retained. But pictures, music, videos - no. Therefore, it is worth initially saving important files somewhere.

Sergey. I noticed one unpleasant thing - after the upgrade on the Honor 8x, the built-in player, which I had previously used to listen to music, stopped functioning.

Possible Solution. Some create an additional folder with music through a computer and then record it on the phone. And everything starts to function as before.

Oleg. Updated Honor 9 on my own. The phone has completely stopped accepting SIM. And when they try to get through to me, I simply don’t notice it. No sound. There is no vibration. Although I set everything in the settings.

Answer. Perform a factory reset while maintaining a backup copy of your data. This is done through the Recovery menu. If the problem is not solved, then repeat the operation, but without copying the backup copy back. If you need to save your contacts, just copy them somewhere. And then stuff it manually.

Olga. I have Honor 8. Updated. Now a message pops up on the screen all the time asking that various programs and servers be able to search for Wi-Fi networks, even if there are connections. Very annoying.

Solution. You need to go to the wireless network settings and deactivate the Wi-fi function.

Tamara. Before the upgrade everything worked fine. Now something is wrong with the charging. The battery seems to be charging. Shows one hundred percent. But after a few hours the phone switches off - I have an Honor 8, by the way. Or I turn on the camera, the reboot begins. And it shows that the charge level is zero.

Solution. There is a high probability that your mobile phone battery is faulty. And the situation can only be corrected by completely replacing the battery.

Alyona. On Honor 10, after, of course, the next update, serious problems with the camera began. The image always turns out cloudy!

Answer. There were problems with auto brightness adjustment and focus sensors. If it is not possible to correct the situation programmatically, then you will have to take the smartphone to a service center so that specialists can look at it.

Anton. I have Honor 8x. Completed the upgrade. And problems with communication began. The Internet is working. Everything is fine. But at this moment people are trying to call me and I seem to be in no access zone. Then a message comes that they called.

Solution. If the settings are set to 4G, then you need to go to the mobile network, then to the preferred mode. Choose auto instead of 4G.

Igor. I switched to EMUI 9 on my Honor 8. It works stably. But there is one problem. The sound became much quieter.

Answer. Another option is to roll back to factory settings. Or use the so-called engineering menu for more precise settings. It is called by a special command – *#*#2846579#*#*.

Matvey. Suddenly the microphone on the Honor 9 lite stopped working completely after an automatic update was performed. I tried all the settings. There is no effect.

Answer. I had the same thing. I never found the reason. But a simple reboot of the phone helped. Perhaps this is some kind of temporary glitch.

Semyon. Honor 8x after the update is now incredibly buggy when playing. Everything slows down and barely starts. Some applications do not want to be activated at all.

Recommendations. After the next update, the smartphone rolls back to the battery saving state. Low performance. To return everything to the way it was before, you need to go to the “Battery” section through the settings. And set “productive mode” there.

Natalia. I use Honor 10. I updated it just a couple of hours ago. After that, they started calling my husband’s phone and asking what happened. It turns out that both of my SIM cards are now, for some unknown reason, unavailable for calls.

Solution. You need to go to “wireless networks” and “Mobile network” - through the settings of your mobile phone. And set “auto 4g/3g/2g” there.

Yaroslav. I switched to EMUI 9. Now the video simply cannot be played on my smartphone. Not at all. I have a ten from Honor, if that's the case.

Recommendations. You need to use the Google Market functionality to first completely remove and then reinstall the proprietary Huawei Video application.

Oksana. On my Honor 8 Lite, after I installed Android Nine, the video from the camera began to be recorded in some FHD format that was incomprehensible to me. And so, later, problems arise. For example, such a video cannot be inserted into VK. Or to other social networks. Even on a computer it does not always play. It is necessary to initially throw it into a special program and change the format. Very uncomfortable.

Solution. You need to go into the camera settings, which are accessible when you use it directly. And deactivate the so-called decoration mode.

Marina. On the ten from Honor, after updating the system, notifications completely disappeared from the status bar. Previously, I was satisfied that they were bred there. Now you can easily miss it if something comes to your smartphone.

Answer. Through the gear icon you need to go to the notification settings. Perhaps, after upgrading Android, the necessary parameters were reset. And they just need to be returned as they were before.

Tatiana. With my Honor 20, I avoided most of the troubles that other owners of similar smartphones encountered. True, there is one unpleasant and very incomprehensible moment for me. After switching to EMUI 9, the volume buttons decrease and increase volume only in multimedia applications. For example, when I watch some video. But now it’s impossible to adjust the ringing sound in this way.

Solution. If you go to the sound settings, then in the new firmware it is now possible to select the task of assigning these keys. You can set the volume to normal sounds for calls and messages. Or leave it only for volume when playing multimedia.

Andrey. I use Honor 5s. After switching to the new system, I can’t log into my Google account at all. I enter the correct passwords and email addresses. Does not work!

Possible Solution. Alternatively, you can try to reset these parameters through the engineering menu. Or go back to eight.

Bogdan. The NFC chip has disappeared on Honor 8! Or rather, it seems to be functioning. But when I try to use it to pay in the corresponding terminal, nothing happens. Although just yesterday everything was fine.

Answer. You will need to roll back the settings to their original ones using one of the available methods - through the regular menu or through Recovery. It is better not to touch the application itself, since resetting it will not give the desired result.

Olga. Of course, we changed a lot in Android 9. And a lot of things that are now very unusual and not convenient. For example, the network icon and the Wi-Fi icon, for some reason, have been moved to the left side of the screen. Is it possible to return them back?

A comment. Unfortunately, this will always be the case in the new version of EMUI. Therefore, you will just have to get used to it. Over time, it is guaranteed that this will not cause any inconvenience.

Maria. I often use my Honor 7 to watch videos. I'm still a movie buff. And before, I would calmly turn on the file I needed, sit down, and enjoy watching it. I installed a new system. I start watching the movie. After a few minutes the screen simply goes blank. And you need to constantly activate it. Naturally, this is very inconvenient. After all, you can easily miss an interesting moment. Or your hands will simply be full. I tried to look for a solution in the parameters, but I couldn’t find it.

Answer. There are actually parameters. It’s just possible that you’re looking for them in the wrong place. You need to go through the settings to the section called “Screen”. There is such an item - sleep mode. You need to use it to set the parameters correctly. And then the screen will no longer go dark when watching a video.

Semyon. I use Honor 9 lite. After the upgrade, very serious problems began. The network is constantly lost. The phone is always being searched. As a result, it became impossible to use it. I'm always out of touch - people complain. Constant searching drains the battery.

Solution. Initially try to roll back to factory settings. If this does not help, return to the previous firmware version of this operating system.

Georgy. Initially, according to advertising, I liked the new system. And visually it did not disappoint. I immediately checked the functionality of the main functions, given the large number of complaints. It feels good. And she calmed me down. Until I needed to launch some application. I'm trying to log in - it's not working. I choose something else - the same thing. As a result, of the several dozen programs that are installed on my Horor 20, only a smaller part started. What could be the reason?

A comment. The reason, unfortunately, lies in the tense relations between the United States and China. And in the so-called trade wars. As a result, at the moment, owners of some Chinese smartphones are faced with a problem when applications downloaded and integrated with Google services simply do not function on EMUI 9. And the only solution in this case is to return to the eighth version.

Reset to factory settings and remove custom firmware

If the user uses custom firmware, then there is a possibility that the firmware does not match the configuration, which causes the system to work slowly. In this situation, you should remove the firmware, or even better, not install it.

It is much easier to return your Android device to factory settings through the settings, backup and recovery section and selecting the master reset section.

For some cases, other methods can be used. For example, on Sony XPERIA phones, factory settings can be restored using the Sony PC Companion program, which should be installed on a laptop or computer. There is own software for models from other manufacturers.

This process looks better than performing a general reset directly on the gadget. Then the device will definitely be in a clean state, just like after purchase.

If all this does not help, you will have to use the Hard reset function. It is advisable to use this technique only in the most extreme cases.

Hello. My Samsung ran out of memory due to downloading movies. Applications began to work intermittently: VKontakte and Google Pay. I cleared the memory, but the applications still don't work well. Please tell me what to do?

Good afternoon Tell me, the Samsung A30s started loading everything related to video very slowly. YouTube is almost impossible to load.

Hello Alexey! I have a new phone. Brand HUAWEI Y5 and almost from the first day problems started, pages load very slowly and all programs work slowly. Can you help me?
