The Samsung S4 phone has just updated the system, and the splash screen appears, how to solve it

I'm the same as you,Upgraded the latest version and there was a flickering screen,Later, I brushed countless ROMs,Now I think it's a hardware problem,Of course, the baseband of the mobile phone also plays a certain role,The main thing is that the design of the SIM card slot of S4 is not good enough,Open the 2G data network is easy to affect the normal operation of the Hall sensor,The solution is the same as the hardware reorganization of the computer,Remove the SIM card slot and reinstall it,It's best to pad what isolation sheet between the SIM card slot and the motherboard,Or replace the SIM card slot, That's how my splash screen was solved. I have been studying it for 2 months.

Here are a few things you can try for this kind of problem:

1.To turn off the brightness auto-adjustment function, you can remove the brightness auto-check by pulling down the top curtain menu.

2.Eliminate splash screens caused by conflicts with third-party applications. Back up your phone's data (**thin, SMS, multi**data, etc.), and try to restore your phone to factory settings (Settings - Account Tab - Reset - Factory Reset).

3.If the problem still exists, due to the limitations of the network, bring the three-pack voucher and send the mobile phone to the nearest Samsung service center for testing.

You go to the settings and find the developer options, go in and find the transition animation scale, and set it to off. Try it, mine will do.

Brother tells you a way to try to turn off the developer options button Mine is good now Telecom version gets s4

Cover the original Holler in the phone with tin foil to solve the problem.

The developer's selection of animation ratios is all turned off, which has been resolved.

We recommend that you perform the following steps:

Reason: When used in a darkly lit place, the brightness of the screen will automatically dim, which may cause the screen to jump and flicker.

Method: [Settings] - Display - Brightness - Remove the check of [Auto Brightness].

Reason: There is an item [background color] in the battery saving mode option, and if this option is turned on, it will also cause the screen to flicker.

Method: [Settings] - Power Saving Mode].

Why: The two options are interpreted by the system as follows: display screen update (flashing the screen when updating) and strict mode (make the screen flash when the program is performing a long operation on the main thread).

Method: [Settings] - Developer Options] - Remove the checks of [Display Screen Update] and [Strict Mode].

Reasons caused by third-party lock screen software: It is found on the Internet that a small number of people have installed third-party lock screen software or themes that cause splash screens, and some are caused by incompatibility with the system.

Method: Uninstall the third-party lock software or third-party theme.

Reason: Some of them appear to be flashing when surfing the Internet, such as turning on [mobile data] and [wifi], after analysis, it is believed that it should be a problem of poor network signal, but there are also places that cannot be explained.

If none of the above methods can be solved, then you can only re-flash the system, which is the best solution, and it should not be after flashing.

Is it flashing as soon as the traffic is turned on? If you don't turn it on, don't flash it, and don't flash it when you use wifi?

In fact, it is the Hall sensor that is out of order because of the magnetic field generated by the traffic generated when surfing the Internet.

Hall Sensor: Automatically recognizes when the (adapted) case is on or off. Typical application: Samsung S View Cover case.

May I ask if you have fixed it, mine also doesn't know what to do.

Settings - Developer Options - Display screen update, there should be that setting, just don't tick it.

Cover the Hall element in the phone with tin foil to solve the problem.
