[Q] Battery gets hot, screen flickers and dies?

[Snowleopard1900]

Hi,

I have a Galaxy Note Pro 12.2 and the battery gets really hot and then the screen starts flickering and eventually goes out. I was wondering if anyone else has had or heard of this issue?

Thank you, Snow

While doing what sort of activity at what brightness level? There is s flickering issue that isn't necessarily related to heat which is why I'm asking. .

These things are rated save to use up to 80ºC, so unless it reaches near-melting temperatures, something else is probably wrong.

There are a couple of threads on screen flickering issues. Primarily concentrated issue on the WiFi and AT&T models.

It has also become a bit of a trend for people to say 'It gets really scalding hot', whilst it turns out to only be around 40ºC. That is not hot. That's normal for a device with a powerhouse CPU and no fans.

Use CPU-Z to get the actual battery temp. 25-45C is perfectly normal, 50-60C in heavy usage is also normal (Games, for instance).

This primarily happens when playing games or watching video's on it. It seems like the processor/battery gets hot and then all of a sudden the screen starts going crazy.

Enable developer options and disable hardware overlays within there. It has been said that this should fix the flickering in video playback.

Be aware that when you reboot the tablet you will have to disable hardware overlays again.

If you're rooted and have TWRP, clearing cache and dalvic will resolve the flickering for a period of time (days) without having to dive into developer options.

Hi IbrahimGla,

Once the hardware overlay issue was mentioned, I looked for instructions on how to turn hardware overlays off on the Galaxy tab (Which where hard to find). Here are the instructions and so far, it looks like it is working for me:

To fix flickering in video:

Enable developer options in settings (go to about device and tap Build Number 7+ times).

In developer options, under hardware-accelerated rendering, check "turn off hardware overlays". You can also check "force GPU rendering", but I've found the former is all that's necessary.

I am having a similar problem with my Note Pro. It ussualy starts when the battery is down to 60%. The screen starts flickering and then I get a message saying the SD card is corrupt or not formatted. Sometimes it locks up as well. Sometimes when I plug the charger in to tells me "charging is suspended due to high battery temp.". The device is warm but not extreamly hot. If I turn the device off and let it charge, once the battery charge comes up to 70% I can turn it back on and everything works fine. As long as I keep it charged to over 60 - 70% I never have a problem. I tried several different SD cards but that doesn't seem to be the problem.

I have contacted Samsung but the only response I have gotten from them is "have you done a factory reset?".


Not sure what to try next. Anyone have any suggestions?

Sorry I missed this, I am not on here very often, I am back because the Note 7 is coming out. I have never replaced the battery on mine, so I am not sure. Apparently replacing the battery has worked for some people. I ended up sending the Note Pro to Samsung 2 times under warranty and the problem was not fixed.

Finally I called their support back a 3rd time near the end of the warranty period and said: Listen, I have send this *** to your repair department 2 times already. I want one that actually works sent back to me. They sent me a Note Pro in an un-marked (maybe a re-furb box?) with some sort of bar code sticker on the back of it.

Since then, this different Note Pro has worked for the most part, but every so often it has minor issues with it getting hot and the battery loosing charge, but it is not as bad as the one I bought. I really think Samsung dropped the ball on that tablet and they are lucky I just got a Tab E.

Definitely not my experience with the Note Pro. Mine has been rock solid for 2 years now, I still rack up a minimum of 2 hours of screen on time per day 7 days a week, and quite often more than that.

Just an FYI that there has been threads posted about screen flickering and battery issues that document issues with the battery connection and how to resolve them (involves opening the back and resoldering the battery terminal). Definitely something that you'd think Samsung would do but doesn't always do it . .

My tablet had the same screen flickering and getting hot problem. I solved the issue by soldering the battery connector in the motherboard. If you look at post #10 of this thread you will see a very good photo posted by Beut of the tiny black connector that seems to be failing. Other users report that the white battery connector also causes problems. In my case it was the black one, I soldered it a month ago and the problem was resolved.
