Buying a new smartphone is often ruined by the discovery of problems in the system. In this case, the operation of the device may not be correct, so the joy from a new acquisition may be short-lived. To eliminate possible unpleasant surprises in the future, it is advisable to check your Android for errors using special applications. Our article will tell you how to carry out this simple manipulation.
The second common method of solving such problems is to use engineering codes specifically designed for your phone model. This method is also effective, but it has a significant drawback - some Chinese-made smartphones may not support such manipulations.
Phone Doctor Plus
Phone Doctor Plus by iDea Mobile Tech Inc. also used to diagnose Android devices. The application provides the most complete information about the state of the phone's hardware. The user has 25 different tests at his disposal. The main window contains detailed information about various sections: “External equipment”, “Sensors”, “Internal equipment”, “Wireless communication” - plus information about the battery, memory, processor, network.
You can test multi-touch, display, speaker and microphone, flash, camera, proximity sensor, memory, gyroscope, vibrator, GPS and much more. Phone Doctor Plus also monitors your device in the background. You can share the test results via Facebook, Twitter or email if you want to inform your friends. Unlike Phone Tester, there are no ads.
Checking the memory card for Android errors
If the selected program cannot determine the exact cause of the problem, but system crashes occur regularly, the best option would be to scan the memory card. This is where infected files can be stored, because to optimize the internal memory of smartphones, most users prefer to save all applications to removable media. Checking the memory card for android errors has its own characteristics, which the information provided will tell you about.
Preparing the sd card for troubleshooting:
- Remove the flash drive from the phone. Using a card reader connected to a computer, you can format and scan a memory card.
- A similar manipulation is also possible using the smartphone’s operating system. To do this, in the memory settings you need to remove the flash drive and format the information on it.
- There are special applications that also check the functionality of this node. Among the most popular are ScanDisk, Hard Disk Low Level Format Tool or SD Formatter.
The functionality of modern smartphones is improving every day, but virus software is also evolving. To protect your phone from possible malfunctions, even unnoticeable at first glance, there are many useful applications. Our article will tell you how to fix errors on Android when connecting to a PC or through downloaded applications.
Dead Pixels Test
Phone Doctor Plus has a built-in test that allows you to check your phone's display for dead pixels, although it does not fix them. But Dead Pixels Test will simultaneously test the smartphone display for dead pixels and fix them. To do this, a series of scans is launched.
Using the “Color” item, you can run a background color run to check for dead pixels or subpixels. To do this, simply click this menu item, select colors one by one, and carefully examine every inch of your smartphone screen.
Once dead pixels are detected, you can start the screen repair process. At this time, it will flash in different colors (red, green, blue). The app fixes partial sub-pixel defects, dead pixels, dark spot defects and more.
The testing process takes very little time, but the result will please you. Remember that stuck pixels caused by device defects cannot be fixed and will require a replacement display.
How to diagnose a phone
There are a large number of programs to check the characteristics or performance of a device based on the Android operating system. Some show detailed characteristics and can help experienced users in many ways, while others allow, for example, to check the screen for dead pixels and evaluate its quality. I have selected several of these programs and will try to tell you what is good about each of them.
Test Your Android
The first program in the “rating” is Test your Android. This is a kind of comprehensive device test that will help identify many problems. Immediately after launch, we see a lot of tools, divided into several groups: “Device Information”, “Hardware Testing”, “Sensor Testing” and others. Some categories store information about the central processor, internal, external and RAM, data about various hardware, battery and many other important components of the device. Here we can learn more about the mobile phone.
If we need to specifically test something, then go to the “Equipment Testing” section and look for the icon we need. For example, here you can check the operation of the touchscreen, check multi-touch, the functionality of the camera, microphone, NFC, speakers, identify dead pixels on the display, or even check the quality of the fingerprint scanner and GPS.
In a separate section you can test sensors: compass, accelerometer, proximity sensor, pressure sensor, gravity sensor, humidity sensor and more. In general, this is a really powerful program that can help you in many ways, we use it.

Device Test
The second program in line is Devise Test. As the name suggests, this is also a kind of comprehensive test that will help identify various problems on our device. We launch the utility and immediately get access to the main functionality: tracking, test, report.
The real-time tracking feature shows you what's happening with your phone. That is, it shows processor load, memory status (external, internal and RAM), displays battery and network status (data transfer, Wi-Fi). Next comes the “Test” function. Here everything is implemented a little better than in the previous utility, since everything is done automatically. We select the items we need for the test and click “Test phone”.
The third feature of the utility is the provision of a report. In this section you can learn in text and tabular form about almost all the characteristics of your phone (or tablet). All data is structured and presented in a convenient form. Also, for convenience, you can send them to your email.
Fix Dead Pixels
Fix Dead Pixels is a program specialized in treating the display. It only weighs a couple of megabytes, but can be of great use if you have problems with the matrix. Here the functionality is as simple as possible and there are only a few buttons: “Pixel check”, “Pixel treatment”. The first helps to identify dead or “stuck” pixels in manual or automatic mode. The second deals with treatment and a software method for eliminating detected dead pixels.
Of course, in most cases, dead pixels are eliminated by physical intervention (replacing the display), but it won’t take much time to try this treatment program. It takes about ten minutes to run the test and almost the same to try to fix the problem. I recommend it because it can really help.
Google Device Assist
Quite an old diagnostic application from a Google device. In general, this will not help much in conducting any comprehensive testing of the smartphone to identify any problems, but it can help in mastering the new gadget. There are a lot of tips and tricks here regarding the set of functions and even a couple of options for quickly diagnosing your device.
This didn’t help me much, and the program can no longer be found on the official Google Play (it was published back in 2014 and disappeared without a trace), but why not try it.
Phone Doctor Plus
Fifth is a utility called Phone Doctor Plus. Here, too, everything is quite obvious from the name. This is a kind of doctor for a mobile device, which allows you to fully check all components of the device for similarity to the original. To be honest, this test should not be given great importance, since it is not entirely clear how it is carried out. For example, on my ASUS ZenFone ZB602KL, some modules turned out to be only 70-80% original, although the overall result was 100%, and the device was never repaired.
The program has many functions for automatic and manual testing. The automatic one is, apparently, a check against the databases of the developer of various hardware modules in the smartphone, and the manual one allows, for example, to check the same display for dead pixels, camera operation, etc. In general, a good utility.
AIDA64
If hardly anyone has heard of the previous, and indeed all other programs (and I haven’t heard of it myself), then many should know about AIDA64. This is truly a legendary program that appeared once on Windows and allows you to view the characteristics of the device in a beautiful and convenient form.
Experienced users especially love the program, but it will be easy for beginners to understand. Immediately after launch, we see a list of categories: “System”, “CPU”, “Display”, “Network” and so on. In the first tab you can find out all the information about the system, that is, the name of the device, its platform, amount of memory and functions. In “CPU” you can, in turn, learn a lot about the processor. The number of cores, frequency, model of the chip itself, technological process and many other important things will be shown here. We go to any category that interests us and get useful data. Perhaps the best program in my memory that can introduce you to a complete list of device characteristics.
Phone Tester
Another application that offers the functionality of several programs at once. Here you can not only view the characteristics of your mobile phone, but also conduct a test. You can check the sound, display, Wi-Fi, charging, vibration motor, SIM card operation and much more in a couple of clicks. Just click on the “Start” button, then select “Phone Test” and the option we need. The big minus is that everything here is in English, I had to translate it manually.
In the “Phone Info” section you can learn about the main characteristics, processor, video core and memory. But all this is presented in some kind of sloppy form, and there are also many unnecessary points that are incomprehensible even to me. A novice user may encounter information that is incomprehensible to himself, or rather, even unnecessary and useless information. I could only recommend the utility to experienced users, and even then with a stretch. The lack of Russian and sloppy design, along with a not entirely logical interface, spoil everything.
System Repair
We close our list of the best programs for diagnosing a mobile device with a utility called System Repair. Here my English is already enough to understand the whole essence of the title - system repair. Unlike the previous utility, the interface and design are a little better here, the only thing that gets in the way is annoying advertising.
Immediately after installation, the program prompts us to repair the system. It's not entirely clear what she's going to fix without running any tests. During such a repair, we are shown a running list of applications and the repair progress: “Fixing System”, “Remedy Boot”, “Fixing Files System”. The application analyzes all installed software. After completing such a repair, no results are displayed - it is not clear what exactly was “repaired”. OK then. Go ahead.
In addition to “repair”, the program helps clean up debris, speed up the device, or optimize battery consumption. If you are interested, you can try, but it is unlikely to be effective (considering how System Repair “repairs” the device). In the “Device Information” section you can familiarize yourself with the main characteristics of the device. Go to the section and select the element we need. For example, if you want to learn more about memory, open “Memory”.
Sensor Box
Sensor Box is designed to test various smartphone sensors. The program tests the accelerometer, gyroscope, proximity, light, temperature, sound, and pressure sensors. Of course, temperature, pressure and gyroscope sensors will not work if the device does not support them.
The application allows you to find out about the presence of sensors in your smartphone: for example, Poco F1 does not support a temperature and pressure sensor. The built-in Tool Box utility allows you to check information about the status of the memory and flashlight. This is not much, but given the “narrow specialization”, we have included it in this list.
AccuBattery
The AccuBattery app, which monitors and optimizes battery health, has over 1 million downloads on Google Play. This is one of the must-have applications when using an old smartphone that has a reduced battery capacity.
The main functions of AccuBattery are measuring the actual battery capacity for comparison with the nominal one, determining the discharge rate, the level of battery wear during each charge, and monitoring charge consumption with a separate application. There is also a paid version of AccuBattery, which has a little more functionality - dark mode and more detailed battery usage statistics. In addition, there are no advertisements.
Fixing errors on an Android phone
Detected faults can be roughly classified by selecting the most common and frequently recurring ones.
Among the “leaders” in the work of Android, the following positions are distinguished:
- Lack of memory. The easiest way to fix the problem is to regularly clear the cache of downloaded applications.
- Wi-Fi authentication failed. Most often observed when the router is incompatible with your device. It is recommended to configure the network manually, using the instructions for your equipment.
- Loading errors. The problem is almost solved on new devices. For smartphones with an older version of Android, it is recommended to additionally use ES Explorer.
- Syntax error. Occurs when files with an incorrect extension are loaded. It is recommended to manually correct incorrect data.
- The keyboard is not working correctly. The built-in Android AOSP keyboard has many shortcomings and incorrect operation. The best option would be to completely remove it from the phone and download a new program from Google Play. You can select an application by rating or number of downloads.
