Since latest update settings won't open at all, just "settings keeps stopping" error message. I have tried the suggestions I have seen on another post (soft restart; remove night mode button from main drop down menu), but all other suggestions I have seen online require accessing settings (not helpful!), e.g. clear cache, force stop.
I am loathe to do a factory reset, but if I need to I can't back up my mob as usual as that requires accessing settings!
(Going to try and backup at least pictures via USB, can I access anything useful via USB to help with this issue?)
Have you tired wiping the cache partition yet? You can do so by following these steps:
After doing this open your settings and see if the symptom still persists.
Let me know if this helped!
Thank you for following up. Do you experience these symptoms if you test your device in safe mode? If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identify and remove the app that may be causing the problem.
