XZ2 gets stuck / stalls regularly

Hi there,


my XZ2 (H8266, latest patch level) regularly gets stuck / stalls: After interacting with the phone, the processes suddenly become much slower, the UI almost gets unresponsive, and it seems like the pone takes ages to execute processes. Only a restart helps. I couldn't figure out what triggers this behaviour or if it is caused by an application running in the background.

Any hints how to fix that or how to debug it?

Re: XZ2 gets stuck / stalls regularly


As you thought, it's probably an app misusing the phone's resources. And to pinpoint which app is causing this you may try the following:


- The "Support" app: From Settings -> Support, check "App issues" for some clues.

- Remove or disable antivirus, cleaners, and memory management apps.

- Factory reset or better software repair using Xperia Companion and begin from the scratch. Monitor your phone's performance with every app installed.

Yes my XZ2 does the same after a few days of being on, only a restart will help. Says system UI not responding and Home launcher not responding sometimes. Phone gets laggy and unresponsive
