Database Info

Android OS used 500+ MB this month.

I'm on the team venom Rom and I checked my data usage, because I got a usage warning, and Android OS is using a lot of data. Last month it was 700+ MB. Anyone know what is going on?

WiFi Barely Functional

So for about three weeks, using this phone has been a hellish nightmare. I can't use WiFI for more than 3 minutes before it stops working. The only way to restore functionality is to reboot it, and I love this phone, but that issue is keeping me from enjoying the phone. Anyone know why it's doing this?

Just curious if anyone else has seen this. It seems to be counting down also since the first time I saw it was 2 days ago and it said "12 days..." instead of 10. However, I couldn't seem to make it pop up yesterday, but today it's back. I hope it's real.

Estimated battery life wrong value

Since a few days I've noticed that the estimated battery time left shows MILLIONS hours. I don't know if this is due to the last security update. Could you give me a clue of why is this happening? Thank you

Mine is estimating only 7hrs, this is disappointing.
