Why my Samsung A20 Screen stack?

Hello, this is Bing. I’m sorry to hear that your Samsung A20 screen stacks frequently. It sounds like you have a problem with the screen or the software of your phone. Here are some possible solutions that you can try:

• Force restart your phone. This can help to fix minor glitches and refresh the system. To do this, press and hold the power and the volume down buttons together for 15 seconds or until the Samsung logo appears on the screen¹.
• Run your phone in safe mode. This can help to determine if the problem is caused by a third-party app that you installed. To do this, press and hold the power button until the power menu appears, then tap and hold the Power off option until you see the Safe mode option, then tap it². If your phone works normally in safe mode, then you need to uninstall the app that is causing the problem.
• Reset your phone’s settings. This can help to restore the default settings of your phone without deleting your personal data. To do this, go to Settings > General management > Reset > Reset settings².
• Wipe the cache partition of your phone. This can help to clear the temporary files that might be corrupted or outdated. To do this, turn off your phone, then press and hold the volume up and the power buttons together until you see the Android logo, then release them. Use the volume buttons to navigate to wipe cache partition and press the power button to select it².
• Update your phone’s software. This can help to fix any bugs or issues that might be affecting your phone’s performance. To do this, go to Settings > Software update > Download and install².
