Has anyone seen this? On my screen brightness says i cannot go above 75% to avoid overheating I'm livid it just randomly said this! I want my full brightness

Yup I just wrote about this in a separate thread...you have to wait until the phone cools down before you can raise it back up to 100%!!!...Has you phone ever overheated to the point that you can almost burn yourself? I've hit temp as high as 121º!!!

How are you checking your temp? Mine gets pretty hot too, wondering if I got a lemon....

Can I ask what you are doing if anything to cause the temp to get so high? I have to admit I haven't been doing much calling or texting lately but do stream internet radio in the car and its alittle warm but nothing like this.

on the droid charge I believe if it gets too hot you can't charge it either, so I'd expect this to be the same.

As far as I know you have to be rooted but I have both SetCPU and CPUMaster, which is free on the Market

2x it was only charging, but both times i left the display on, but still that should matter, I should be able to leave it on all day and not EVER get past 105º at most!!! and the 3rd time I think I was playing NOVA 2, and when I got out of it, went back to my homescreen, left the phone and after about 2/3minutes it was blazing hot!

system panel displays temp too, probably battery monitor widget as well

[Q] lg g pad over heating

Recently I bought the device ,it worked great at first how ever now it tends to heat up too much and because of that the device writes a message in which registered over heat turning off Because of extreme Temperature the device turns off.
does this problem happens to you too ?

This is the first I've heard of it but you obviously have to return it for abother pad. Even with the aluminum back mine only gets warm at the most

it happens only when i am trying to benchmark it , have u tried it and what version is your device bcz i think its a software problem .

I've only noticed the device getting hot when I benchmarked it over and over again to sort of stress test it. From regular use it does get warm (all devices do, including cell phones) but I've never had overheating problems.

Um, don't do that then?

This just occurred on mine last night
This just happened to me last night. It auto turned down the brightness and said it was overheating. I was not doing that much.....I wonder if the battery is going bad....

LOL yea not sure why he's putting the fault on the tablet. All devices will heat up from excessive benchmarking.
Although, during my stress testing it did get hot but didn't give me any errors or shutdowns.

I was not using it that long. Less than 1 hour, just doing some surfing, a little candy crush. I am in USA. The battery power was less than 25% when this happened.

Mine gets warm after an hour of gameplay and stays warm until i stop lol. I DO NOT get the warning message though. It's normal to get warm but if you get that message constantly then exchange it.

Mine has done this before while playing riptide. I had my brightness at 95% and it turned it down and had a toast warning. I really think it is the design of the tablet and this can happen if you push the tablet hard at full brightness. I haven't seen it since. This was back in December so I wouldn't be too concerned If it doesn't become a normal occurrence. I have owned many android tablets and this one definitely runs the hottest.

I have the same issues guys... this tablet has design issues. If you charge while using WIFI boom u got over heating. also without charging normal usage will trigger overheating i have recorded temp going more than 70 Degrees until it shuts by itself.
I had replaced my tab once but the new unit has the same issue.!
Any fixes so far?

....same to me.
any suggestions?

Screen temporaroly dim on left then slowly brightens from left

Hi has anybody had this issue?
Sometimes the entire screen goes dim (I don't mean normal screen time out where it turns off). My entire screen (often while in middle of playing a game) will go very dim, mainly on the left, then gradually lighten from the left to the right and then go back to normal.
I'm not sure if this happens more or less often when the battery is low, I haven't noticed that yet. I keep it in a gel case and have only ever dropped it from low height onto very squishy carpet...
Also my charging flap is loose and won't stay in and charging port seems a bit finicky >.< I really like this phone, it's a shame.

My charging flaps loose too,vi think its a problem on this model, but no problems with screem brightness. Do u have auto brightness on?

Yeah also I noticed that when I turned the screen off, it was not actually off, it was a dim black (light emitting). I restarted my phone and that particular fault has gone away and now turning off the screen is actual black.
The right-hand side of the screen also felt like it was moving/clicking slightly when I pushed it but I pushed it a bit harder and that stopped. I hope my screen hasn't somehow become loose.
I'll have to check if I'm still in warranty.

[FIX] "screen flicker, screen freezes, and random restarts with low battery" SMT700

[FIX] "screen flicker, screen freezes, and random restarts with low battery" SMT700
When The Crashes happen: Usually the tablet will crash on Google chrome When the Battery is below 60% and around 15% it will simply crash on the lock screen.
People say the fix for this is to Re solder the battery clip or give it to Samsung to fix
Well I did find a fix But you need ROOT Access
How to fix. First you will need to get a app called Kernal Adiutor. (Link https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=en )
Once this is installed You will want to open it and set these values (If you find more stable values tell me and i will edit them here)
Under CPU: (Minimum Frequency: 200MHz) (Maximum Frequency : 1100MHz (Most stable) or 1900MHz (Unstable)) (CPU Governor: Power save) (multi core power saving: Aggressive)
Under I/O Scheduler: (Scheduler: fiops or zen) (Read Ahead : 4096kB)
Under Entropy: (Read: 128) (Write: 512)
Feel free to post better values in the comments
I hope this helps!

boop

I have have the same issue but on the 705 under cpu Governor i have of those settings only ondemand, userspace and interactive...
also on i/o i only have noop, deadline or cfq.... any recomendations as to which i should use would be helpfull

I don't know about this app helping with this problem. But one thing is sure. Taking off the back cover of the tablet(cleaning the antenna contacts) and unplug/replug the battery helps. After this process the battery holds longer.

I had this problems (random reboot, screen freeze and crazy screen flickers with bright flash bars), which occured when it had low battery (below 40%).
I removed the back cover with a guitar pick, unplugged the battery, waited a couple of minutes and put everything back together again.
Until now zero problems, longer battery than ever... So I believe in most cases there's no need to spend any money or send it to RMA.

If you are having these issues, check to see if you have "Turn off hardware overlays" enabled in developer options. If so, disable it. This worked for me and was the only difference between my current Tab S and my old Tab S before it died.

Just have service center change your battery and check its connection.
I have it changed within 3 months after got it bcoz of said problems & everything is fine since till now....
Its been almost a year & the tab's still OK.

Hairline fracture in the display causing the screen to have a permanent green/yellow tint. If I grabbed the top left and bottom right corners and bent the tablet inward at the center of the display, it would go back to normal. Burn in started to become an issue as well due to the damage done. Technically it didn't die. It was just cheaper to buy a new one so I did and gave the old one to a friend.

I also had flickering and restarts. Removing the battery and plugging it back in fixed it for me.

Same here it got so bad I couldn't even use my tablet. I cleaned out the battery connectors with rubbing alcohol and firmly reconnected them. I used not be able to get below 20% battery without the tablet rebooting like crazy and screen getting glitchy. Today I finally was able to completely kill the battery without a single glitch or reboot.

Unplugging and replugging in the battery for permanent fix but requires you to open the case

So just as simple as that? I´ll give it a try.

Exact same problem with my T800. Just straight death the second it hits 58%. however, turning on stock power saving mode (along the same lines as OP) did the trick for me. Not a single crash since then, with both Loli and MM. Also downloaded kernal adiutor and ran it ontop of powersaving mode to overclock\undo the horrendusly slow state. Meh sounds counterintuitive but it worked.

i tried opening the covere method it worked for me but the problem keeps returning after 3-4 months.

OK, I think I'm having a similar problem. I replaced the original battery a couple of months ago and everything was good for a while. For the last 2 weeks, I've started having a problem where the tab works ok when it's fully charged, but when it gets down somewhere below about 65%, the tablet will sometimes just turn off without a warning. When it does turn off, the only way to restart it is to briefly plug it into a power source. You only have to plug it in for a few seconds, but when you do, you can turn it on again. If you don't plug it into a power source briefly it simply won't start at all.
Once you get it started again, it will run for a few more minutes, before it again fails without warning. Once it starts doing this, the time it stays on gets shorter and shorter until you recharge it completely.
Yesterday, I got a second replacement battery to see if that would make a difference, but it behaves just like the first one. I tried unplugging and replugging the battery connector, but it seems to be firmly plugged in and doing that doesn't help.
I'm thinking that it could be firmware corruption problem, so I'm thinking that I will do a factory reset, reformat, reinstall, etc. That's a real pain and I'm not confident that will fix it. Does anybody have any thoughts or suggestions?

The original battery in my Tab S finally died after holding on for 7 years with the annoying green flickering, but fixed it temporarily by unplug and plugging it back in , changing the battery solved it , got replacement battery on February 2021 , 6 months in and the problem is slowly starting to come back , i might consider soldering and strengthening the battery connector like most other forums and answers i found so far after extensive research..

Diagnosing soon-to-be-bootlooped phones

Looks like somebody on Reddit had a talk with one LG representative in which he described a method to diagnose if your 5X is about to get bootlooped.
The procedure as follows:
Turn your phone off, or let the battery discharge completely (which I personally recommend);
With the phone off, plug in the wall charger.
If your phone only displays the battery icon and starts charging, you're good. But, if your phone starts to boots up -- displays the Google logo and starts the boot animation -- expect your phone to brick soon.
Also, the manufacturing date seems to have a role in this case as well, looks like most bootlooped phones have been manufactured in October of 2015. I have a H791 manufactured in November 30th 2015 with no problems so far -- I've dropped the phone a few times (with the case), used the advanced governor tweaks, overclocked, applied thermal tweaks, rooted and restored the phone a dozen without any issues so far.

Mine is october 2015, 791. System modified, rooted, overclocked, a lot of fashing mods. Still works without aby issues.
When I plug device to charger, It show battery icon.

Holysh*t. Mine is 791, manufactured Oct 2015. And I always let my battery discharge to zero before I plug it in. I notice that sometimes it boots up and sometimes it doesn't.

my serial starts with 511 so its Nov 2015.. I was going to root my phone until I read about the boot loop plague think its safe to?

thats bad for the battery mate plug it in around the 30% mark

What if every 5X hardware eventually degrades with time, someone whose phone is not booting today might boot up one day in future while charging, and eventually end up bootlooping.

Lol mine's H791, bought January 2016 and it died 1 week and a half days ago, never tried any other ROMs except being stock itself and occasionally changing kernels and recovery, also I never remember anything it boots up after charging my phone being discharged completely

Unlikely, since not all 5X's are affected by this. Besides any manufacturing issue (the bootloop cause), specific material characteristics (like the normal wear and tear of lithium batteries) or environment, electronics won't degrade up to this level in the medium term.
The charging boot up is only a symptom that something wrong is already going on. LG said that the bootloop is caused by loose components, which can get worse over time by physical stress (see the iPhone 6 touch sickness) or heat.
So, the perfectly assembled 5X's will not get bootlooped and should last a long time.

think it is safe to assume that whatever happens causes the battery to no longer have the ability to charge, on my first 5x the dead one soon as i got it (used) I was iffy about the battery and if it was charging or not I would see charging animation and then other times I wouldn't. I bought a brand new battery off ebay before attempting the FRP removal, just seemed like a smart thing to do, used phone and all, but by the time the phone passed away it managed to fry the new battery as well, I went to use it in the rebuilt from two broken and it would not charge...imagine that

i think there should be something (a tool?) official to diagnose. So anyone can legally ask for a replacement. But i guess that is the same reason we dont have already it
Anyway thanks for the infos, glad to have at least something!

Forget about it, mine bootlooped last week.

For the last 2-3 weeks before my 5x died.. i noticed that restoring a twrp backup was miss and hit, it would(or not) miss some apps or similar..like it didn't restore 100%.
Another thing that i noticed is that when i copy for example some rom.zip or any zip bigger than 400MB on to the internal sd, it would get corrupted, it would change md5sum.
BUT if i reboot the phone and copy the zip on the phone immediately after booting, then it won't get corrupted.
Im not sure if this is directly related to this issue, but it looks like it does.

Guys going to buy two nexus 5x phones , can someone tell me how to accurately check the model number and which model is safe to buy and how to diagnose the phone of boot loop future?
