Galaxy Z Flip 4 don't light up when you open it

[tebanbsc]

Who knows how to fix the typical error of this brand that you open the phone and the screen do not turn on.. 

It is only the magnet problem but it is a nuisance that does not turn on the main screen.

Very bad work by Samsung and they are not responsible for it

Hi tebanbsc,

We understand how frustrating it can be when the main screen doesn't turn on as expected when opening the device. Please try the below troubleshooting steps to help resolve the issue.

Please ensure your device is running the latest version of One UI and firmware: Settings > Software update > Download and install

Reboot in Safe Mode. This helps identify if a third-party app is interfering:

• Press and hold the Power key until the Power off menu appears

• Tap and hold Power off, then tap Safe mode

• Open and close the phone to test the behavior

• If it works in Safe Mode, a third-party app might be causing the issue

Wipe Cache Partition:

• Power off the device

• Hold Volume Up + Power until you see the Samsung logo

• Navigate using volume keys to Wipe Cache Partition, confirm with Power
  (No data will be deleted)

We truly value your feedback and apologize for any inconvenience caused. We are here to assist you every step of the way.

Thank you.

Hello I already did everything you recommend me, even safe mode but it is not software.. it is simply the magnet of the caps that due to the bad validity, ceases to have the same capacity as I have investigated and does not turn it on, since It think it is still closed.. you should fix that in the software that when touching the screen disables that function of the magnet
