System UI & Apps not responding

[AJ1]

Even after normal use System UI & Apps are not responding. Even if I don't use the phone or apps, attach error is displaying on screen. Firmwater version : latest. 087 A9, no latest update received. What can be done on this. Seems there are bugs in system update due to which this error is getting. Everything tried, but same issue getting.

Hi, we'd request you follow the below steps:
1. Clear system cache.
2. Try the same under safe mode:
Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode
3. If still you face the issue
factory reset your phone after taking a full backup : https://www.asus.com/support/FAQ/1006346/
4. Last option would be to visit the service center to have
a check. Locate here: https://www.asus.com/in/support/Service-Center/India
