    My BLU vivo5 updated to Android 7.0 near January 19, 2018. Most of my settings were change. Saved user names/passwords were changed. My phone was put in Do Not Disturb mode. My indicator light never tells me when it is charged. My battery is draining quicker. My alarm randomly goes off 4 minutes late. But my vibrate function is now working.

    I have reconfigured all my settings. I think I have successfully re-logged in to apps. I found where some apps had been switched to "not optimized" for battery usage.

    But.... Why is my alarm going off 4 minutes later than it is set for? It is not an everyday occurrence. I have double checked the time I have it set for - which I don't like the way I have to set alarms on this update. Since its unpredictable, I can't just change the time because what if it is suddenly going off 40 minutes late.

    I'm not sure what you mean by that, but once I figure that out, I will try it.

    The system cache partition stores temporary system data, which can sometimes cause issues (especially after a system update). Wiping it can be helpful, and won't erase any personal data.
