How to remove negativity from an iPhone screen?

Now let's see how to get out of the negative on iPhone: Open “Settings” on your phone or tablet, then “General”, then “Universal Access” and “Color Inversion”. Now the screen will change from black and white to color again. As you can see, there is nothing complicated, everything is quite easy and simple.

Adjust brightness to your liking

Without a doubt, brightness level is very important when using an iPhone. It needs to be correct for the different ambient lighting situations you are exposed to. Obviously, when you are in a dark place, high brightness can eventually damage your vision. In the opposite situation, where there is a lot of ambient light, it is important that the brightness is high so that the information on the screen can be seen. These brightness values ​​can be easily adjusted by following these steps:

• On your iPhone, go to Settings.
• Click the "Display and Brightness" section.
• Stay at the top to adjust the brightness.

The first thing you'll see on this configuration screen is a slider that allows you to adjust whether you want to increase or decrease the brightness of the screen. We recommend keeping it right in the middle at all times, although this will depend on the situation you find yourself in, as we've commented previously. If you don't want to make this adjustment all the time, you can always let the operating system determine the amount of brightness by activating the "automatic brightness" option.

If you want to go a little further in this regard, you can activate the True Tone option that also appears in this part of the settings. With this setting, iPhone will instantly change the color of the screen depending on the ambient light. In this way, less degradation of the appearance is achieved, but the fact always remains that the colors that appear on the screen will not be completely real. That's why we suggest you take a test between activation and deactivation to determine which option is best for you.

Customize iPhone X/11/12 Display Settings to Improve Efficiency

iPhone 11/12/10 display settings are divided into two categories:

• affecting image quality and affecting internal functionality;
• increasing the usability of the smartphone and simplifying interaction with it.

The first group includes: auto-rotate, shift and enlarge the display, divide the screen into two independent parts; the second includes adjusting brightness and color reproduction, as well as calibrating a touchscreen with impaired sensitivity.

Let's take a closer look at how to configure the screen on an iPhone 12 series and below so that it can be used with maximum comfort.

iPhone screen doesn't respond to touches

Android screen calibration - ways to adjust sensor sensitivity

If there is no response to touch, you need to find out why the problem occurred. First, you need to carry out an external inspection to identify physical defects: cracks on the display, chips. You should also prevent moisture from getting into the phone case.

Note! In extreme cases, a hard reboot of the device may be required.

To perform a hard reboot, you must adhere to the following algorithm of actions:

1. Press and hold the “Home” button. If it is not available, later models use a volume rocker.
2. The keys are held for 15-20 seconds. The device will analyze the memory and perform a deep system clean.

Reboot iPhone

If the hard reset method did not help, then you can use the following methods to restore the screen to normal operation:

• completely discharge the phone and wait for it to turn off automatically. Then fully charge the iPhone and turn on the device;
• recovery via iTunes. To do this, you need to connect the device to the computer, go to the program in the “Overview” tab and select the “iPhone recovery” option.

Important! If you restore via iTunes, the smartphone will return to factory settings. All files and application settings will be deleted.

On different devices, the reasons for the lack of response to the sensor may be different. On older models, you can use touch adaptation. What is touch adaptation on iPhone? This is an independent adjustment of the display response time.

On models with Face ID

On iPad models with Face ID, you will need to force restart the device if you experience problems with the display:

1. You need to hold down the volume up button and quickly release it.
2. Then repeat the action only with the volume down button.
3. Press volume up again and wait until the device reboots completely.

On iPhone 8 and later

On iPhone 8 and Plus devices, you can force a restart:

1. You need to press and quickly release the volume up key and do the same with the volume down button.
2. Next, you need to hold the side key for a few seconds and wait for the developer logo to appear on the smartphone screen.

On iPhone 7

For a 7th generation smartphone, the reboot process is slightly different from later models. The user needs to press and hold the top side key until the Apple logo appears.

On iPhone 6 and earlier

On 6th generation Apple devices that use the “Home” button, troubleshoot display problems using the following instructions:

1. Required within 15-20 seconds. hold the “Home” button on the front side of the smartphone.
2. Then wait for the developers’ logo to appear and wait until the device turns on. After this, you can check the functionality of the sensor.

Set your favorite email client or browser as default

Some time ago, iPhone and iPad owners were able to choose a third-party application as their default browser and email client. This means that when you click on a link online, it will open in Chrome or DuckDuckGo instead of Safari.

How to change iOS default browser:

1. Open Settings.
2. Select an application that will replace Safari.
3. Click on “Default Browser Application”.
4. Select an alternative browser.

You can do the same with your email client.

Blocking unknown phone numbers

The devices have a new feature that will allow you to get rid of unnecessary phone calls. As the name suggests, it only blocks unknown numbers, but you can actually block all numbers that are not in your contacts list. Or which Siri assistant did not find in mail and messages.

When you enable this option, you can add messages to voicemail for those whose calls have been blocked but you want them to be able to contact you.

iPad Battery Calibration

The calibration procedure involves zeroing the controller, through which the battery is controlled. It determines to what limits the battery can be charged or discharged. Maximum battery capacity is not a constant number. Over time, its quality deteriorates and it can work less, and the controller cannot take these changes into account on its own. Another malfunction of the batteries is observed after flashing the device. This is why calibration is a highly preferred measure to stabilize battery performance.

To calibrate the battery:

1. Reduce iPad battery charge to zero. That is, specifically until the moment when the device can no longer be started. The easiest way to drain your device is by watching videos and playing installed games.
2. After this, you need to fully charge the battery, that is, until the device reports that the battery is fully charged. A wall charger is best for this.
3. The controller may make mistakes, so you should keep the tablet connected to the charger for another hour or two.
4. Now you should discharge the device again under normal operating conditions. In this case, you cannot connect the device to a charger or PC, otherwise the calibration will be disrupted.
5. We repeat points 2 and 3.

After these measures, the tablet's battery will be fully calibrated. As you can see, this does not require programs, special tools or devices. However, the proposed procedure must be followed exactly. As a result, even a well-worn battery will work at all the power available to it and will be able to last longer.

Night shift, what is it?

Blue light is one of the greatest enemies that exists for eye health as well as regulating circadian cycles. There are many studies that suggest screen time should be avoided before bed due to blue light. That's why this type of light can be eliminated thanks to Night Shift, a special mode that can change the screen color to sepia. Obviously, it is recommended to use it at night to avoid eye strain, although it can be used during the day without any problems. To activate it, you just need to follow these steps:

• Go to Settings.
• Scroll down to "Display and Brightness".
• Activate the "Night Shift" option.

You should be aware that at any time you can select a specific schedule for automatic deactivation and activation. This is ideal so that when the sun goes down, the night shift is turned on and deactivated the next morning.

Reduce white point

Among the iPhone options is the ability to reduce the white point by a percentage. It is responsible for adjusting the intensity of bright colors, which can be very bright. This setting can be very interesting, especially at night when bright colors can be distracting to the eyes. This is an option in the Accessibility section that you can activate by following these steps:

• On your iPhone, go to Settings.
• Scroll to the Accessibility section.
• Open Screen & Text Size.
• Activates the "Reduce Brightness Point" function.
• Make adjustments using the slider that appears.

You will see in real time how bright colors begin to decrease in their brightness, so that the equipment becomes much more convenient to use, this setting can be changed at any time.

How to configure manually through Control Center

If a customer wants to make the screen brighter or darker, all they need is Control Center on their smartphone. In this case, there is no need to go to the settings section. But it is also impossible to activate additional services through such a panel. The operation is performed according to the following scheme:

• the control panel opens on the smartphone;
• to open it, you will need to swipe from bottom to top;
• when the control center opens on the phone, the “Sun” icon will be located there;
• The user can now drag the slider higher or lower.

As the slider moves down, the color saturation decreases. After moving the slider up, the display becomes more saturated.
