The phone always flashes back, and it is slow to return to the home screen

Solution: 1. Too much cache garbage.

Usually in the process of using the software, some junk files will be generated, and if you do not clean it up for a long time, the phone will become more and more stuck, and there will also be flashbacks.

Go to Settings Apps - All - Find the app in question and clear the data or cache. (Note: Clearing data will erase the app's personal settings, account information, etc.) )

2. There are too many running programs.

If you don't set it up, a lot of software will run on its own, and too many background programs on your phone will cause you to run out of memory, which will cause the app to crash. If there is a software crash, you can clean up the memory before trying again.

3. Mobile phone antivirus software.

Some mobile phone software is malicious**, will be blocked by anti-virus software and can not enter normally, should be through the green ** platform or use the software store to ** games with a high security factor.

Note: All three of the above causes can now be easily solved by cleaning up with security software. But you need to be careful when deleting some large files. )

4. Application version issues.

If the version of the application is low, the application software will be incompatible and cause a crash. If the version is too old, you can update to the new version.

For example, if there is a flashback in the new version, the application version is still being debugged, so there is no need to worry, and it will be fixed soon.

5. The system is incompatible.

Some software has certain requirements for the version, if the system version is too low, the software cannot be supported, so it will crash.

6. The resolution is not compatible.

Some software has certain requirements for the resolution of the mobile phone, if the resolution of the mobile phone is not compatible, some software is prone to flashbacks or other errors.

If your phone is experiencing a flickering screen, it is recommended that you:

1.Check whether the "Display Screen Update" feature in Developer Options is enabled: Settings - Developer Options - Display Screen Update - Off (some machine developer options are hidden, if not activated, you do not need to check).

2.Observe after shutting down the machine and restarting it.

3.If the mobile phone can be used normally, it is recommended to check whether there is a new version of the machine system and upgrade the system to try.

4.If that doesn't work, back up the data (contacts, text messages, **, etc.) on your phone, and then restore it to factory settings.

If the phone cannot be operated normally or the problem persists after the above operations, it is recommended that you bring the purchase invoice, warranty card and machine to the local Samsung after-sales service center for professional engineers to help you test.

It's already the latest version.

The question is a flashback on the negative screen of the mobile phone.

Reason 1: Too much mobile phone application cache Android phone due to system characteristics, in the case of too much mobile phone cache, it will cause slow operation and flash backlash. Solution: You can use a variety of cleaning software to do a deep scan of your phone, or go directly to [Settings] - [Application Management] - [All] to find the apps that are in trouble and clean up the cache or data. (Note:.)

Clearing data will erase the app's personal settings, account information, etc.).

Reason 2 There are too many programs running in the background of the mobile phoneMany friends often do not really quit an application, but habitually return to the desktop, and the program is actually still running in the background, when there are too many programs running in the background, it is likely to lead to the phenomenon of flashback. Solution: When you don't use a program, you should actually quit instead of returning to the desktop, clean up the software running in the background frequently, prohibit self-starting apps that you don't use often in permission management, and uninstall software that you have barely used. If necessary, you can root your phone and delete some of the built-in apps, or disable some apps from starting in the background.

Reason 3: A small number of third-party applications in mobile phone antivirus software are malicious** and will be intercepted by antivirus software, resulting in flashbacks; In addition, mobile antivirus software can sometimes misjudge the app, causing it to run abnormally; At the same time, if you install several antiviruses, conflicts with each other can also cause crashes.

Reason 4: The application is not compatible with the system, the lower version of the application is not compatible with the mobile phone's system, or the mobile phone system version is too low to meet the requirements of the application, which will lead to a flashback.

Solution: If the application version is too low, uninstall it and reinstall the later version, and if the mobile phone system version is too low, you need to upgrade the system. If you still get a crash after installing the new version, it may be that the version is still being debugged and you need to wait for the system to be repaired. However, because there are many models of Android phones, it is impossible for application developers to take into account every model and every system version, so this situation can only be fed back to the application developer to solve.

Reason 6: Missing Data Packets: When running the game, due to the lack of data packets, it will also cause a crash.

Reason 7 Modify files after rootNow many users choose root (jailbreak) to get more permissions, especially to beautify fonts, at this time, if the font library is not complete, the application will not be able to open the application according to the font used, and there will be a flashback. At the same time, root may also delete some system files that are needed by the program, making the program not work properly.

Solution: If the font is missing, you can restore the phone to factory settings (pay attention to back up important data); Check if you have deleted any files by mistake, or system programs, if you have, you need to go to a repair shop or **flash or root and other software to unroot.

Reason 8: Programs conflict with each other, if the open program conflicts with other running programs, it will also open and close quickly. Workaround: View running apps from the background, close conflicting apps, and restart apps that will be used.

Hello, it may be 1, too much running in the background.

Software requires memory to run, and many people are aware of this. If you run too much software at the same time, and the phone's running memory does not slow down instantly, it may cause the phone software to crash, and in severe cases, it may also directly go black.

You can close some of the software in the background process; Or limit the capacity in advance in the background process limit to avoid flashbacks.

2. The software version is too low.

Every software will be updated and optimized from time to time, and if you don't upgrade the software, your software may not be opened when the developer no longer maintains the version. In order to have a better experience, the software should be upgraded.

3. The system version is too low.

The system also has its own version, and every upgrade has an optimization. Similarly, if the old version has a small user base, the developer may stop maintaining it, and at this time, there will be big problems with the use of your mobile phone. Therefore, the system should also pay attention to upgrading to a newer version.

4. Software conflicts.

Some software is not compatible with each other, just like we can't have two **software at the same time**. In the case of all three reasons, you can consider the case of software conflict. You can choose to close one of them and replace it with a small program or other software.

This is mainly for Android users, some systems are special, and there will be more and more cache data of the app in the mobile phone. When this data is overloaded, there is a chance that the software will crash. For these cached data, it is best to clean it more, and you can use the phone manager that comes with the phone to clean it.

After using the mobile phone for a long time, it is inevitable that there will be various problems, such as the mobile phone screen flickering or blurred screen. So what to do?
