Weird heat while charging

Hi,
i've been using the GNEX for almost 3 months, it had been rooted and used the AOKP ROM since i have bought my phone. And just last night, while i charge my phone as usual when i got home then i went to a bath, then when i came out and pick up the phone, the back left hand corner is producing a lot of heat!! then i unplug the usb cable immediately and turn off my phone, after around 3 mins, till the phone had cooled down and i thought it was just the cable's problem, so i switch the Nexus S' usb cable instead of the GNEX original one, and it happens again in just 3mins!! so i switched the battery again which both of them are original ones, charge it with my phone on. and it just happens again!!! so i switched off my phone and charge it, and it just charge normally without generating weird heat...! strange!! so do anyone know what's going on with my phone?? should i unroot it and take it back to samsung? please, needed help!! THX!!

weird heat... that doesnt say much since the way you described it might be weird for someone and normal for someone else. whats the battery temperature? whats the cpu temperature?

You've had your phone for nearly 3 months and this is the first time it's getting hot? LOL anyway sounds like something is using the cpu...

hows this for weird heat? but its not really weird, its normal for being at 1689/1689mhz, running a bunch of benchmarks, wirelessly tethering, and being plugged in.. 100C cpu temp and 109.4 battery temp

this was above and beyond normal use, lol. but, for what i was doing to it, it was normal
(i did turn off heat throttling, btw, or the cpu would never get that hot)

nope, i set the cpu at 1Ghz and turned on Airplane mode.

GPU fault after falling

Hello guys. I'm currently trying to fix a friends HOX that fell and now the screen doesn't always display image although we can see it always lighting up (it turns on but stays black) .
If I press hardly the HOX's area in red while turning it ON, it works fine. I'm assuming this could be some broken welding points but would like your opinion.

I'm thinking of heating the area with a heat gun, but I'm afraid I'll kill the rest of the phone... what do you think?
Also, after disassembling the phone, the vibration stopped working and I've checked every flat cable and every connector I could find...no ideas to fix this one since it was working before I cracked the phone open.
Any comments are greatly appreciated.
Tks

Possibly a chip has become partly detached from the solder ball grid array due to the shock of the fall. You will not be able to repair this by heating, even if you could reach the melting point of the solder.
The manufacturer would repair by replacing the circuit board and the existing one would be considered unserviceable.

So in resume, my friend has a HOX for spare parts... damn...

Couldn't you pack the inside of the housing at the point where you need to apply pressure? Using a piece of card or something. Hardly ideal but would make it functional again

That has been my first attempt, and it's better but still, not enough.
I'm going to disassemble it for the tenth time in a final effort...
tks for the tip though!

So, I've just realized the back metal plate comes out nicely and I think I've found the problem for the GPU issue... that small component on the red area has a broken piece lol (WTF!)
I have applied pressure directly on top of it and I think it will be usable like this, but it now needs a bit of daily use to check if I'm right or wrong.
Can anyone identify what component type is that?
Also, unfortunately (and I don't have a clue how this has happened), the vibration stopped working after opening the phone on the first time, any one has any ideas of what to look for? I don't see any flex cable cut or any other damaged parts...
Tks guys.

Problem solved, some back pressure on the broken piece and the hox is good to go.
The only thing still not working is the vibration...

Crash at 80% battery

Hi my tablet is crashing every time the battery is lower than 80% (it turns off immediately) end keeps crashing every time i restart it and begin using it after 2 or 3 seconds and the battery drains every restart .Is it surely a battery problem or it could be caused by anything else?

Probably you have a cracked battery connector, common problem of Samsung tablet. Re solder will fix this problem, you can verify by removing the back cover, apply directly pressure on the black battery connector and turn your tablet on; if it works, problem solved, just find someone or a repair shop to help you to re solder the battery connector.
Don't forget to fix the white battery connector too, it's also the source of problem

thank you for the reply I unplugged the black connector and re-plugged it and the problem seems to be fixed but i didn't find the white battery connector

Unplugged and re-plugged battery helps to solve problem, then you may need to do this little fix of the white battery connector. I had one battery which didn't take charge, after this simple fix , it works normal again.

You need a thin knife and magnified glass to do this fix, push the opening as close as possible.

Anyone else had their display loosen at the top?

I've noticed this on my phone, and my Nan's. Both 3's, not 3T's. Both have loose screens at the top. - I can lift it up a lot. See photos.

Wonder if this is a more widespread problem, I've bought a Tudia case as it wraps over the edges of the display and holds it together, preventing it from worsening and falling apart.

Yep, i have the same issue on the top right side of the phone.

Seems to be a common issue. Wish OnePlus would approach it like apple does their "gates". But that'll never happen.

They can't even push more than one or two updates, let alone make a phone like they did during the days of the op1.

This sucks. I run LineageOS with a Locked BL, my friends and family also do with the 3 & 3T.

That sucks. If spontaneous and not from damage... it's a manufacturing defect.
&
It could be a battery failure although that battery is in the lower quadrant I think.
Especially after a year old keep an eye open for signs of swelling.
Any battery swelling is a battery failure, replace immediately.

No battery swelling on 3 units with this issue.
End of that theory

Been an easy fix... that really sucks☹
On some phones it bulges and/or pushes out the display, on others the rear cover*.
At that point it may have already damaged the display or more.
This type of battery failure is fairly common.
Replace degraded Li's once they reach 80% on their original capacity.
Degraded Li's are more likely to fail.
Failures include thermal runaways...
*I had a failure on my 10+ recently and was luckily it didn't damage the display. The battery wasn't quit 1.5 years old.
Erratic fast charging is another sign of a failed Li.

Correct. I always charge at 2A and use Accubattery for monitoring. Unless I am in a rush, then I fast charge.
And yes, it is an easy fix, when it isn't the battery. But the displays are weak on the OP3 & 3T - and as a result, its easy to fek this up.
I once had a HTC One X bulge so badly it pulled the screen up about 2cm and broke the entire phone. Since then I've always taken care of batteries.

Battery is too cold (preventing charging)

Hello,
Apparently my Samsung Note 10+ battery temperature sensor stopped working and I need to ask you a question.
Whenever I try to charge my Note 10+ I get an error message saying that my battery temperature is too cold, it prevents me from charging the phone.
I downloaded an app that measures the temperature of the battery and it says that the temperature is at -20C.
I've already tried to leave it turned off, on, near a heat source, near the hair dryer and so on, none of that works, the cell phone is too hot, but this warning that the battery is too cold continues...
I also tried to disable fast charging/wireless charging, formatting etc, but nothing had any effect, the only thing I didn't do was unmount the phone.
Anyway, my question is, the message that prevents my phone from charging is probably from the operating system (OneUi or Android 11), my doubt is: if I install another operating system/Custom Rom, there is a possibility of " cheat" this message that prevents the cell phone from charging?
Thanks !

Replace battery. Pretty sure that's where the failed sensor is located. See if you can find a source toverify this.
If so it may indicate a battery failure as well.

Samsung has a thermistor that communicates with the power IC that is probably damaged. Replacing it will help you resolve the problem.

I tried to find the thermistor for the battery temperature with DevChek. All the reported ones didn't correspond to the reported battery temperature. My deduction was it was the battery it's self. Probably more likely for better responsiveness.
An easy fix if so... the C port pcb is also cheap and relatively easy to replace.
Regardless until it's fixed, it won't charge. It's an important safety feature.
You could try a hard reboot in the off chance it's a freak glitch.

In order to overcome the water damage problem, all you have to do is to:​Clean charging dock strip and check.
If the problem persists or if the pins are damaged then you need to replace the entire charging dock strip.
Now check the voltage of the 1st pin (from right) of the charging connector with the help of a Multi-Meter, if there is a problem then re-solder the charging pin.
Now check voltage at the capacitor, if it is zero then check whether it is short or not if it then changes the capacitor. If not then:
Check the connection between the charging pin and Capacitor, if the connection is broken re-solder it or place a jumper.
The charge is provided to the Samsung Galaxy Note10+ board via Capacitor.

That gave me a headache...
This seems more likely.

Great find. I like when people share their take on problem solving. Collective thinking is what helps us all make progress.

Was the phone dropped or exposed to water?
Probably for a device of this value a good repair shop be the best option.
Use DevChek to try to ID the failed thermistor circuit. No circuit schematic makes troubleshooting more difficult...
It could be something other than a failed thermistor. Low temperature thermistors seldom fail; a failed or loose connector, solder crack or mobo trace failure are just as possible.
