How many have sent N4 in for repair?

Title pretty much says it all. Also, could you state what you sent it in for? I currently am having issues with it thinking it's charging when it's actually not, and am considering calling LG to send it in for repairs.

what do you mean by charging when its actually not? is it charging USB when its plugged into the wall?
plug it in the wall and then check about phone -> status.... does it say charging (USB) instead of charging (AC)?

nah, when it's unplugged the phone thinks it's charging. battery icon has the lightning symbol, lockscreen says charging

sounds like a software problem. flash a custom rom and kernel (optional)
not worth RMAing it just for that. if it still does it, then flash it back to stock and u may RMA if all else fails.

I read that you have one year of waranty.
My N4 have the same problem, but I dont know if Google accept it with the bootloader unlocked however I think my phone is fried, so, how can they know if phone even turn on..>>?

i sent mine in, dropped it and got a crack in the screen and the touch stopped working. Hopefully I'll have it repaired soon. Not covered under warranty because it was physical damage.

PROBLEM after 4.3 upgrade

I have galaxy s4 i9500 model, after 4.3 official update, everything isn't working correctly
My phone keeps repoting it self and when it starts after that rebooting it goes in infinite loop showing samsung logo and rebooting.
I remove the battery and put it againg then start the phone, it starts but shows that the battery is low eventhough It was over 50% before rebooting, when I checked the battery somehow it feels like it became bigger pregnant ! !
Can anyone help me on how can I downgrade from 4.3 to 4.2.2 before I lose my battery.

Well it's better to loose your battery then your phone,
officially samsung confirmed that they have shipped a large quantity of S4 with a bad battery you can reconize these battery because their serial is starting with BD
battery is slightly swelling up or is already bigger.
I was in the same situation as you,
the phone kept rebooting and stuck at the samsung logo the only way to get through is to plug in the power supply.
you have a use battery drain before rebooting about 87% after just 1 %. once you are booted the phone will reboot during an incomming call or simply when you try to sent an sms
this behaviour has NOTHING to do with any custom ROM available here at XDA
my advice is change the battery asap because the longer you wait the more the risk of a battery exploding,
exchanging battery is still under waranty
I hope for your sake it's not going to explode when it's in one of your pockets of your pants, at that moment you damage even more then just your phone :angel:...... and we don't want that to happen.
good luck

mmmmm
My battery starts with BD
so this means that I have one of the phones with the problem ?!
so changing the battery will solve my problem and this has nothing to do with my s4 hardware or ROM
another question
does changing this battery goes under the warranty or should I buy it on my own ?!!
thanks a lot for your reply

most likely yes
and yes again changing the battery will solve your problems (I know so because I had the same experience)
and no it has nothing to do with the firmware/hardware/rom on your phone
since Samsung confirmed that there is a problem with a serie of batteries it will be replaced under warranty
glad that I could be of assistance

Thanks again, I will go replace the battery ASAP.

S4 Green Led always on

Hello everybody,
Yesterday I had a new issure with my i9500. The green led stays always on, even if the phone is turned off, the only way to disable it is pulling out the battery. Now, I know I have a faulty battery, I was at a Samsung Service Center and they ordered a new on for me under warranty, which should arrive in the next few days.
Do you think it is possible that the battery is causing it?
thank you very much!

Is the phone plugged in when it happens?
If so, it is just a notification indicating that you have a fully charged battery

It happened to my i9505. Took it to service center and they ended up replacing the whole mainboard.

Galaxy S5 not powering up after the "Samsung Galaxy s5" screen appears

My perfectly working Galaxy S5 was put for charging at night and the phone wouldn't turn on in the morning. I tried restarting it and at times the "Samsung Galaxy S5 - powered by Android" flashes for a second or so and then the phone dies again.
I tried rebooting it, unplugged/replugged the battery, removed SIM and SD Card and tried to start the phone but nothing happens. On charging the phone, the screen does come up to show that the phone is being charged and as of now it is 100% but still won't power up.
I must add that the phone has had its share of falls during the 2 year usage and there is a small discoloration / crack like effect on the top left hand corner of the screen which however cannot be felt by hand by rolling my finger on the screen.
Samsung guys claim it a screen problem that needs to be replaced however an independent repairer is confident that screen is OK and it has something to do with some other hardware of the phone. He even removed the battery and connected a multi meter to the point on the phone which connects to the battery, tried starting the phone and the meter would show some current getting drawn and then come back to zero. He claims phone is not able to draw current from the battery.
Any clues what could be the problem and how to rectify it. I have loads of data I don't want to lose on the phone.

Can you boot into recovery? Have you tried flashing a new firmware on the phone?

Phone isn't responding at all. No matter what I do, at the most the Samsung screen flashes for like 30 seconds and then the phone dies again.
On connecting with a computer the computer begins to recognise the phone and starts installing drivers for the same however it never completes the job.
So not sure how to flash a new firmware if the phone isn't responding at all.

Bumping the thread.

Another reason for this behavior is that the battery has no charge. Battery can be damage and no have charge at all
I would in this order
do you have another S5 available?
exchange batteries and see behavior
do not have another S5 available?
try to charge with a universal wall charger.
or it seems you have a tester. Make sure your battery have charge

Checked battery too but that doesn't seem to have a problem. Tried with other batteries also.
A local repair shop told me there's a problem with the boot IC.
My follow up question is can I replace the mother board with another Galaxy S5 motherboard? Are all the motherboards of Galaxy S5 compatible with each other?

I'd be careful when changing the motherboard. You *DO* need to find a compatible board...In other words which ever variant you have should be the variant you look for to source the donor board.
Also, you say you have data you want to recover? Swapping out the motherboard will remove every possibility of recovering that data; as all the flash storage is contained on the motherboard.

How to locate a compatible motherboard? In other words how does one identify the variant of the phone?

All the information you need is on the sticker underneath the battery.
Sent from my SM-G900F

Interesting piece of information.
I took the phone out almost after 8-9 months today. Tried to power it on by pressing the ON/OFF button and the phone came back to life without a glitch. There was almost 52% charge, date and time were spot on. I couldn't recall the pattern, as a result I couldn't unlock the phone.
I decided to wait for a while for my partner to come back and put in the correct pattern password and left the phone unattended for a while. In between I kept checking and the phone remained ON all the time.
Unfortunately, I decided to charge the phone while my partner returned. After half an hour or so I pulled out the charging cable and checked the phone for 1 last time. Phone was still ON. I left it untouched for a few more minutes.
As soon as my partner came back I told her about the phone coming back to life. She pressed the ON/OFF button to bring up the screen and key in the pattern but the screen just didn't come up. I have tried number of times since then but nothing.
Phone is dead again atleast as of now. Thinking of keeping it back for few more months and will try again.
In the meantime any sort of help will be highly appreciated.
Please note more than the phone I am keen on the data inside it. Need to recover it.

Galaxy S10+ shuts down randomly, does not turn back on.

Hello
So, I've got Samsung Galaxy S10+ AT&T model with a very very weird issue.
The phone has so far died 4 times already. After each time I take it to local Samsung Service center (I'm in Europe) and the technicians turn the phone back on after plugging it to a device which directly sends the power to motherboard, excluding the battery. But the thing is that solution is temporary, the phone developed this issue on January 10th this year and since then I'm kind regular visitor to the local Service center.
They can't determine what's causing the issue. If anyone here has experienced the same issue and found a solution for it I would be more than grateful if you could share it with me.
European authorized service center can't do anything with US models, basically Samsung's warranty works only regionally and not worldwide, well, shame on them for that. Will think twice before buying next Samsung phone.
Couple facts:
1. The phone does not force restart when dead.
2. The phone takes minimal charge when the issue shows up, the technicians at local service center said it takes about 200mAh when dead while it should be doing around 2000mAh normally.
3. Windows 10 PC does recognize (plays sound) that some kind of device is connected when hooking up the dead phone to it, but the phone does not show up in device manager. Also Odin or any other software can't detect it.
4. The only temporary solution so far is to hook the phone up to a Samsung device which sends the power directly to the motherboard, so the power does not go through the battery, but the battery health is excellent.
If additional details are needed I would be happy to provide them, let me know!

I have my old Note 3 (T-Mobile branded) that does that i could never figure out what causes it even after going back to stock original (unroot). Only difference is mine does take a charge and charges fine in your case either
1. You charging port is damaged in some way causing not to charge properly
2. (Unlikely) but battery is defective somehow and won't hold a charge
3. Your cpu is overheating causing a shut down

Thanks for the reply.
Well I think mine is quite a different of a scenario
1. The phone charges fine until it's working, it functions like a normal phone before that random shutdown occurs.
2. I too had that doubt, but it lasts very well so not sure about that.
3. The phone gives no signs of overheating ever. Not even while charging. The random "death" scenario occurs randomly when not on a charger. The phone is sitting in perfectly functioning state and the next moment you take it to unlock and suprize, surprize... it's dead. So far only temporary remedy is to take it to the service center and plug it to the special Samsung gadget to directly send the power to motherboard.

If your phone is still under warranty i would ask them to replace the motherboard, it sounds like it's defective in some way.
