[Q] Touchscreen Issues, Ghost touches, etc...

Recently my Nexus 5 has been acting weird. the right side of the touchscreen sometimes becomes completely unresponsive and sometimes phantom touches occur. I've tried reinstalling android and the problem is still there. I've noticed its gotten better once i removed my screen protector but from time to time the screen still acts up. I was thinking maybe it has to do with humidity or temperature. Anyway has anyone else had this kind of issue? Any suggestions for a fix other than replacement?

is this happening when plugged in/charging only

No it seems to happen randomly even when not charging, really weird

i asked because thats common behavior for a malfunctioning charger or one with too much voltage.

Yeah I've heard about those issues with charging, but I'm using the charger that came with it, that shouldn't cause any issues right?

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

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.

Thanks for your reply , i did what u have mentioned in the begening of my problem and no thing has changed , now after a month from the first time where my screen starts flickring the device is not turning on it is like a device with no battery it just show me the battery charging when it's off.
do you advise me to buy a new battery and replace my note pro battery??
Thank you & sorry for my bad english

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.

Should I try again?

Hey guys I needed your help with deciding if I want to give the 12.2 another chance. I bought a tab pro 12.2 Wifi, and it worked great for a 8-9 months. While it was working I loved it. Then I had the battery drain issues all the way to the point it wouldn't turn on. Did a factory reset/tried all the tricks to get it to turn back on as well to no avail.To make a long story short I bought a new charging port(wouldnt turn on),then bought a new battery(turned on up to 60% and eventually ran out and died again). Still have the stock charger so thats not the cause either. I wanted to know if this was just a faulty model I purchased and its the exception and not the norm. Any longtime users willing to chime in with their experience and convince me to drop $600+ again.

I've had mine since 9 may 2014. (The P905 LTE). Never had any issues with battery.
Your issue is certainly not the norm, or the model would've been pulled off the market a long time ago.
The only issue mine has is that sometimes the touchscreen driver crashes upon wakeup. It cames back up after a minute or so. But that's fully firmware-based and I'm simply too lazy to reflash. xD

8+ says overheating and not warm

My unlocked s8+ has just started telling me it's overheating when it's not even hot. It's not eve n warm really. Says cpu is 126c I think. Might be degree. I forget.

Hi. I just did. We'll see how it goes. This issue started after the last system update. Grr. Never happened before.

I would check this out, if i was you.!
Reason,
one of my old Samsung phones, infact
a Note 8.0 Tablet, started with this
is same issue...." overheating" noticed
I ignored it for a few months.
as tablet seemed to be working fine.
Eventually, i then, started get to a point
when i get the "message" my tablet
would stop charging.
I had to wait for a while and try charging again.
After, many months (maybe +- 7..8..9 months)
My tablet did not want to charge. anymore.!
I eventually took tablet to a
Samsung Care Centre
It was the USB port/ charging port ... (ok we now have a C port)
Replaced port and all was fine again.
I would say don't ignore this "overheating" message.
Good luck

Thanks.
I'm not ignoring it as that's why I posted.
I don't want the phone if it continues this. So I don't know what to do if it happens again and it's still not hot.

I would take it back to a Samsung service center or call them.
I would also take screenshots of overheating message and if it follows any pattern.?
Use screenshots as you "proof" of the overheating issue.
Otherwise Samsung would just check device and say device is ok.
(You have to be fast as i know the overheating notice
only appears briefly for 3..4 seconds..?)
I personally believe that this "overheating" is a start of hardware issues... not a software issue.
You have factory resetted your phone, so if it
appears again at later stage... hardware issue!
I also factory resetted my old tablet and all was ok for a while... then overheating notices started to appear again.
Good luck
post note
Forgot, yes in beginning my tablet appeared / also did not feel hot. Reason why i ignored it.
Also thought /hoped it was a software issue.

Phone shutting down

Red_shift said:
Hi everyone, my Note 2 shuts down when the temperature is moderately low (under 15 °C / 60 °F)
I thought it were a battery problem, since I still used the 2013 one with which the phone was originally shipped.
But buying a new one didn't solve the problem.
I tried swapping batteries with my girlfriend (who has the same model of phone, without the shut-down problem) but this didn't work too (regardless which battery I use, my phone shuts down, hers not) -- unfortunately I thought of swapping the batteries only after buying the new one...
So I thought it could be some sw problem and flashed a new ROM (crDroid 7.1.2)
I'm very pleased since this is much better than the stock ROM I had before, but the shut-down-in-low-temp problem still rears its ugly head (maybe a bit mitigated).
E.g. today I went skiing and carried the phone in the breast pocket of my jacket. Outside temp was about 2-5 °C, so it wasn't really cold, but the phone shut down.
When I tried to power it on, it wouldn't until I carried it home and put it on recharge.
After a few minutes of recharge, I could power it on and the battery was at 98%...
Any ideas of what the problem could be? Something hw?
If nothing else works, I theoretically could take off the display and digitizer of my phone and connect it to a third Note 2 (which display was broken by my girlfriend some time ago, otherwise it works fine), but I hope there is some simpler solution because I've never done something like that...
Thank you for your help!

No, therefore I was asking.
Did you move my question here?
I posted it in the Note 2 forum, wouldn't it be more IT there?
Thank you!
