Thanks for your comments and suggestions.

I have download logcat and bugreport from my A2107A-F tablet. I am putting some lines of these log files at the end of my message. By my side, after reading the logs I couldn´t find anything that can be considered the cause of the problem. Maybe If somebody of you can take a look at the logs and give me his/her comments, I will be thankful.

But still, I need another help:

I think, if the problem is related to hw it could be due to a faulty temperature sensor inside the mainboard or a battery problem. I have installed "Smart Battery" aplication and noticed that every time the warning message appears the battery temperature is above 50°Celsius and when the charger is connected, battery temperature goes down around 35°- 37°C. In order to discard battery problems it is possible that somebody of you could install the same app in an -F model and do the mesurements in two situations: one with the power adapter connected and the other without it. Also in both cases the tablet should be playing a video. I just want to check if your tablets are showing same °C values or different than mine.

Also I will change the stock ROM and will see if the problem persists. :fingers-crossed:

ssenemosewa:

did you have the same issue in the past?

Issue: Over Battery Temperature warning: Your battery is over temperature, please power down.

Two options: Snooze or Dismiss

Result: whatever option you choose the tablet shuts down.

ssenemosewa . thank you for your comments.

In order to discard if it is a battery problem, may you try to take the measurements that i explained in my prevoius post?

Also I am agree,about the reported temperature, it is unrelated to the actual temperature, also many people commented the same in other forums.

In my case, the tablet is worse than before, every time I turn on the tablet, after boot process is completed, the annoying message appears around the next five minutes and the tablet shuts down. What is curious, it does not happen when I turn on the tablet while it is connected to the usb port of my laptop.

And yeah, the warning appears many times when the battery is low (under 40%).

About Shiloh´s ROM, specifically what ROM did you install?

A2107A-F_S483_121115.zip or BareBones_Alpha_7.zip

I should give it a try !!!
