Multiple weird issues.

[trestontape]

I am running Android 7.1.1 Nougat. Anyway, recently, I had a full charge. The percentage would not go down under 99%. I even ran a game that crippled this phone to its knees and it still wouldn't go down. I restarted it and it started going down in blocks very fast around 3% each. Then it stopped around where I think it would go. 2ND issue: sometimes wont charge for some reason. 3rd issue. Sometimes im just playing and my phone shuts off with the not. Light blinking red 3 times. OCCASIONALLY when that happens it will say the phone is dead but it isnt. 3Rd issue. Sometimes the background will put the bottom half of itself where the top would go and causing it where it used to be to be black.

Try pressing the Volume up and power button at the same time for a few seconds until your phone vibrates and reboots, this might clear anomalies in battery percentage. 

You can also try to you perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to backup using Xperia Companion, but preferably without adding apps or settings to the backup.

Follow the steps given in blue links, and keep us updated.

Thanks, but the display still has issues. The first issue was solved, but the 3rd and 4th were from a loose cable.
