[Q] Galaxy Grand I9082 China Telecom Gets Super Heated & Draining Battery

Hi, need some technical advise on this issue. Apparently, I have a set of Galaxy Grand from China Unicom. The thing is that it is on stock. I gets heated up super hot whereby I can feel the blistering heat and when plugged in to charger, it just discharges and not charging. The phone is hot with or without charger plugged in. It has never went to water contact before. I am puzzled, I can't flash it to any other firmware as I've read the I9082_CU phones are sort of like firmware locked. The phone will keep on draining battery until it kills itself off. The only way to charge it back is for me to charge the battery with external charger.
If anyone has any insight of this issue, or have a schematic diagram for any jumpers to the mainboard, please share thanks. I suspect something is drawing power or a blown capacitor or resistor that is causing this. Another thing is that whenever I try to activate the wifi and bluetooth , it just says " Turning Wifi On" or "Turning Bluetooth On" it stays for a couple and reverts back to off position. However I noticed even in the off position, the WIFI or Bluetooth icon is dimly lit.
I thank everyone for any insight on this.
Regards

phone is getting slower
am also facing the same problem... & now a days am not able to open the google play store, when i open it, my phone hangs & after some times error message wil popup on my screen like "unfortunately google play store stopped", please help me with a solution for this.....

I never knew Grand has a carrier-locked variant... Given its target market in developing countries, not US.
Your best bet is to complain to your carrier and claim your warranty, because it seems like they have done lousy modifications to the phone...

The thing is these phone was purchased from China, didn't know it too that they locked the firmware but after reading from a couple of guys here, it seems it's locked. Battery is draining like crazy , 1% every 20-30 secs. I think it could be firmware but maybe it could be hardware as well

This could be a faulty app/firmware---which can be detected by some system monitoring apps on Play Store---a bad kernel or some faulty hardware...
There's no solution for faulty hardware... just dump it if you can't bring it to a service center
Can you root and install a custom ROM on a locked firmware? (sorry I've never used a locked phone before) This could be a fix if it's a faulty app/firmware/kernel.

UCH12

Hello,
Couple of months ago I bought a UCH12 charger and it was working fine with my Z5 Dual Premium.
But since the update to Android 7.0, it stopped working.
I'd plug the charger to the phone and it would vibrate as if it recognized that something was connected but the phone does not show the icon of being in charge and even when I go check the battery usage it says that the phone is not charging.
My phone is not routed. I tried getting help from Sony support, but all of the action tried (reset, long reset, turning on and off, repair, etc...) did not get any results.
Anyone has the same issue ?

have you tried charging ANYTHING else from this charger?
looks like it's dead.

Yep, a Galaxy S7, works like a charm, just hates my cellphone or my cellphone hates it, either way.

try the same chargers while
1. device switched off
2. charging optimization is off
i suspect that charging optimization causing trouble...

1. Same thing
2. I am not sure where to do that, I have check battery optimization but iit only optimize the charge in respect of the apps used. and it did not do anything.
I admit that this is a strange one, has anybody witness the same thing ?
I can always send it for repair (I am still under warranty) but I'd like to use this as last resort (takes some time and forces me to use a crappy phone).

Settings > About Phone > Status

Tried it, no change...
EDIT:
I wonder if this article isn't saying that Google might be messing with Quick Chargers...

Anyone else on this issue ?

Let me know hoe it goes, because Im having the exact issue. I tried the steps from sukhwant717, but getting stopped at the step when it goes to the OS. Will keep my phone to charge for a few hours. I observe, that there is no heating up (battery), but will keep it for charging anyways.
Cheers

Thanks man....I did actually fix the phone...your awesome.....
It went something like this...
First phone refused to turn on....no charging light notification..it keeps vibrating.
Even @sukhwant717 method stopped at "os" thing.
After exhausting all option taken to a local service person who did something and told phones dead.
After coming home I have checked He RIPPED /SNAPPED ANTENNA cable.
I didn't bother much as phone was prononced dead!
After 30 to 40 days was casually reading @sukhwant717 thread and thought of trying again. I coonected charger and SUDDENLY I SAW ASUS BOOT SCREEN and phone was showing BATTERY WITH QUESTION MARK. I let it charge for sometime suddenly bootloader screen appeared but was not entering into recovery.(perhaps damaged bootloader , recovery).
Then I followed sukhwant717 method flashed bootloader and RAW image using ADB.
and phone RESURRECTED but with very low siganl.
It's due to RIPPED antenna cable.
And was getting good reception on 2nd SIM (perhaps uses different antenna/cable)
So I decided to order new Antenna Flex Cable but it's not available in India. So I went to ASUS SERVICE CENTER (near Brandfactory) in Hyderabad
and asked them the cost of Flex Cable, they said they won't sell spares...I have to RMA.
So I did and after two days I have received a call from them that "ITS FAULTY MOTHERBOARD" and will cost 11000 INR (USD 170, seriously ASUS),I said I rather want my phone in previous condition. I even told them to fix antenna cable ...I will manage.
They said their "TESTING SOFTWARE " failing device test even after connecting antenna cable.so they can't sell a part for a TEST FAILED device.
I told them it's because I had unlocked bootloader..the test is failing.they didn't have a clue abt bootloader unlcoking.
So again went to local market for the cable found A cable (though lil longer) and got it fixed for about 300INR ($5).
and got back the reception and typing with LTE connection on ZF2.
Thanks again @sukhwant717 ...
My observations: the issue could be due to
1) it's battery related issue (completely drained bir failed battery)
2) damaged bootloader
The people who have similar problem should leave the phone uncharged for 30 to 40 days even more and connect the charger and see if u see battery with ? Mark.
Or if new battery is available change battery and check....

if you need antenna cable i can send you. but before that. send me pics of motherboard where antenna connector sits. don't ever believe local and service center guys. they are dumb enough to ruin things.

I had a similar problem, phone suddenly powered itself off and started vibrating. With the phone off and connecting the charger it started to charge, but after a while it started vibrating and overheating. I did a factory reset but the problem persisted. I flashed the raw firmware and it behaved properly for a while, but a few days ago the phone died. It does not turn on, does not charge, screen never turns on, no notification light, no vibration. But if connected to the charger it gets hot.

Left the mobile alone and tried to plug in after 35 days, IT WORKED. At first nothing happened but left it in charge for few hours. Later the mobile came back to life when I tried to turn it on..... 3 days in and still working just like it used to.... will have to take care not to let the battery drain below 20%

I am having same issue .. did you get it resolved ? Any luck ?

hello i'm having the same problem
will this method ensure that my data won't be lost?

A5 2017 don't charge!!

Hi.
This error shown when charger connected :
moisture being detected on the charging port
And phone don't charge.
I have tested this methods :
1:USB port dried by Hairdryer
2:charger and USB cable changed with new one
3:USB settings app that shown the error cleared data.
Also phone booted on safe mode and didn't charge
Phone can't be charge in power off mode too.
Phone Haven't any hardware problem. My friend have this problem on s7 too.
This problem occurred 2 days ago and still now phone can't charge . I'm sure phone isn't wet.
Any idea you have ? Help please

maybe clean your usb port with water and let the phone to dry off . or ask samsung

Tnx for help
I have tested with 2 USB cables and both are clean and dry.
Samsung support fixed that once with reset factory and delete all data.
But again I have this problem. It's not good to reset factory your phone when you want charge that

I had it happen, too. I cleared the USB cache nd rebooted and it's been fine ever since. This was also 2 days ago.

I'm having the same issue with the moisture notification, however, after rebooting the phone and plugging the cable in before the notification would appear, I can charge the phone without any problems. In my case, either corrosion or the moisture sensor's fault is the problem. Should I send it in for a repair? Is this covered by the warranty?

The moisture detected issue

So I am also facing this,
I searched the whole internet (including everything on xda obv) for a solution and nothing worked.
I had this problem that come and go from time to time, but I thought it is because I live in a humide city. I just wait for like 30 minutes and it is gone.
But this time it is different, It occurred after I put the original headset in my phone two days ago. Waited around 2 hours for the error to go. Yesterday, I noticed that I no longer have the fast charging capabilities, only charging (double of the required time to fully charge).
Today the error does not disappear, I cannot plug the headset or connect my phone to my computer, nor charging it via usb cable. This error is annoying and I cannot contact the samsung store due to lockdown. Is there someone who managed to solve the issue without losing the warranty ?
I have other original usb type-c cables at home, none of them is working and all of them are working in my wife's s8+, so definitely it is not a cable problem (and there is no moisture also, my phone had never been in water).
Thanks in advance.

You can try a can of compressed air and blow it into the port to see if that helps. Other things you can try is a factory data reset, put the phone into a zip lock bag with some white rice (leave it in there for a few hours cuz the rice will help pull moisture from the phone) or just waiting to see if it clears up on it's own.
You might also have a USB port on the phone that has failed, which means you will need to have the port replaced.

Thanks for your answer. I am really clueless about what to do to my phone :/
The message can arbitrary disappear after several but once I plug my headset that is working normally in my laptop or in the s8+, I get the message back and it won't disappear. It has been 2 days in a row now while it is on my phone and can't plug anything in the usb-c.

I did everything except the factory data reset, because I find it is meaningless to remove all my data because some port is not going well.
The problem is that the issue may go arbitrary but two things to note:
1. If I plug my headset I get it again (the headset is working normally in all other devices).
2. It won't super fast charge (only fast charge, which get 2 hours to fully charge rather than the usual one hour).

A software setting (database, config file, etc) that goes bad or gets corrupted can effect the charging functionality. In one case before when I ran into similar issues the solution was a factory data reset.
Also you might have a failing USB port on the phone, since you mentioned the issue happens when you plug your headset in and your charging speed has been impacted. You could try different charging cable and/or headphone to see if the issue(s) persist.

I was ready to cremate the thing to get rid of the water issue.
I have remedied it ( I think )
This is the Logical remedy.
Since it has nothing to do with usb cables.
Look at the phone ports..all along the bottom and a couple on top.
TAPE THEM OVER...!!!
So NO moisture can get thru.
So when the moisture warning has gone away..Plug in your charging cable...And tape all along the bottom cut the tape nice so it allows room for the cable .
I have not had an issue..Since
And why should I, ?
Logic says ...there is nowhere for moisture to be detected if all ports are Covered
LOGIC WINS
And Samsung should dial down the sensitivity!!
People will die or have died / Because they could NOT charge their phone to call emergency Services
