This hides everything on screen. So for bringing the required page back(on which I’m working)I have to press central button or arrow button (indicating backwards) to bring the said page back or the home page(which displays main apps).What I think is some reason behind it ,is the setting in which some function like some theme or some such wall paper or some function in display or lock screen has been activated..Thinking so i have tried my best to resolve this issue ,therefore i have deactivated all themes, wallpapers etc but the issue is still there so far..Now therefore you are requested that kindly help and resolve this issue of my mobile’s screen being white again and again after every some seconds and hiding main page or any page at any time..I hope for your helpful and timely reply..

Solution: Before performing any troubleshooting steps on this device it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.

There’s a possibility that this problem is caused by a software glitch. What we will be doing right now is to exhaust every software troubleshooting step required for this particular problem. In case the issue does not get resolved after performing the troubleshooting steps then this is most likely caused by a faulty hardware component already.

Perform a soft reset

The first thing you will have to do in this case is a soft reset which is usually done when a phone becomes unresponsive but is also recommended in this particular case.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Once the phone restarts check if the display works properly.

Check if the issue occurs in Safe Mode

An app you downloaded in your phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.

  • Turn the phone off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occurring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key to highlight “wipe cache partition.”
  • Press the Power key to select.
  • Press the Volume down key to highlight “yes” and press the Power key to select.
  • When the wipe cache partition is complete, “Reboot system now” is highlighted.
  • Press the Power key to restart the device.

Perform a factory reset

One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data before doing the reset as it will be deleted in the process.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Do not install any apps in your phone after the reset. Try to check first if the issue still occurs.

In case the issue persists even after performing the troubleshooting steps listed above then this is most likely caused by a faulty display assembly. The best thing to do right now is to have the phone repaired at a service center.
