[Q] Did my device had sudden death? - Galaxy Tab 4 Q&A, Help & Troubleshooting

Few days ago I left my tablet to go to some place and when I returned the device suddenly "died" - it will not start until I connected my brother's phone USB cable to charge it the next day. When I powered it up, it appeared that the battery suddenly dropped to 0%.
It happened again - I used it tonight, read some articles (had around 30%-60% charge), shut down the screen once, and when I tried to turn it on again, it happened again.
Did my phone suffer from sudden death or what? This is the same guy who tried to change the CSC from France to Singapore (so that's the modification I did so far, everything's the same, including stock unrooted Android 4.4.2).

There are many unknowns: charger, USB cable. or USB charging port. Nobody can give a specific answer except yourself .
This tool will help you to figure out which one is at fault. Step by step should be done : swap charger, USB cable, USB port until problem found
http://www.ebay.com/sch/i.html?_fro...&_nkw=usb+current+and+voltage+tester&_sacat=0
Voltage should be 5-->5.2 Volts, current should be 1.5-->1.7 Amps for working charger, USB cable, and USB charging port.
Search Ebay for USB charging port for your model if you need one. I don't know which size of your tablet but most of them are not expensive, under $10 for USB flex FPCB.

[Q] Charging is only possible through USB

Hi
I have the Galaxy S5 for about 1 month now and I like it very much. But two days before, I noticed issues with charging the phone through the AC Adapter (Samsung original USB Charger) - the phone did not charge during the night. So the phone stopped charging with the wall charger. I tried out many other USB chargers and also USB 3.0 cable. Without success!
It charges just fine when it's plugged into my laptop or desktop PC.
When the phone is turned on and I plug the charger in, nothing happens. The battery condition in android is still "discharging". But when the phones is turned off and plugged into the wall charger, it vibrates in intervals and the screen stays blank (the little battery animation doesn't appear). Removing the battery and replacing it does not help. I tried almost everything...
Has anybody an idea? Otherwise it seems to be a hardware problem. Same issue also here: Androidforums
I'm on OMEGA 5 ROM now with OMEGA Kernel. I cannot believe that the OMEGA Kernel has something to do with this issue.
Thanks for any help

It seems that it was a hardware problem, probably because of some water inside the USB connector. After some days I blow out the socket with a spray duster and since this time, the issue never happened again. :good:
I think, I will never test the water resistance again...
Did water enter the usb port and was the flap closed or not?

The flap was closed of course. I don't know if water has entered into the socket, but I think not.
One day after my post, the issue happened again. Now, I have updated to OMEGA 5.1 and flashed the Samsung stock kernel instead of the Omega Kernel. Now, the issue never occured again.
I cannot believe that this is because of the kernel, because the issue was also when the phone was turned off.
Now for 1 week, I never encountered the problem again

Galaxy s5 won't charge, please help urgent!

Phone had been acting up since Monday night . At first it wouldn't charge with the original charger on the wall outlet so I plugged in the USB to my PC and it was charging perfectly fine. Then all was good until yesterday night when it stopped charging on the wall. It started giving me some error about using a sharing cable (wtf?!) Then I figured OK maybe I should connect it to my PC. So I connect it and it wouldn't charge at first but then it did. Then I started looking up for a solution because I need my phone to work ASAP and it charges way to slowly on my laptop. Everyone was saying do a factory reset, remove the battery put bit back in, maybe charging port is faulty . Then I tried using another cable , I used my sisters s4 USB 2.0, connected it to the wall and it sort of gave it power for like 50 seconds then stopped. Now I'm losing patience here, I go back and forth between cables and wall to PC etc I gave up and turned my.phone off for the night. Wake up , plugged in the wire to my PC and the charging icon with the bolt in it comes on for 5 seconds then turns back off and comes back on . This repeats itself and doesn't stop. This happens when the phone is off and is connected to either the wall or my laptop.

Tldr: phone doesn't charge at all. But when turned off, charging logo appears for 5 seconds then comes off and back on and repeats this cycle over and over. Still not gaining charge

It's your phone indeed, Is your lollipop rom modified in any way or rooted?
It actually WAS rooted before the update! I had it rooted through towelrooot but i unrooted it via supersu so i could install the 5.0 update
So your counter is still 0x0, if so I say take it back to t-mobile or whatever company you bought or you can try buying a wireless charger

SO i have to take it back to my carrier? What if my usb charger COVER fell off? you know the thing that you have to open to plug your usb in and you close when youre done, yeah well that thing fell off the other day and i didnt bring it in contact with water or anything so idk what to do right now
You can find those on amazon for pennies on the dollar
Try cleaning the battery pins on the back of your phone or the battery itself... I experienced the same thing... All I did was file the pins 1 or 2 times and it got fixed. Or maybe try cleaning the USB port of your phone... Base on what you're saying I can say it's just a connection issue that needs cleaning.

Yeah do what @Riyal said I should have thought of that myself
@GuyananV Hey haven't from you what's the situation with your s5?

[Q] Charging Issues after trying every option I can think of

Back in Feb I started having an issue with charging up my phone, went through several cables and adapters. Eventually using a cable was out of the question as the phone wouldn't recognize that a cable was even plugged in. Initially, I would have to fiddle with the plug some to get it work, then that stopped. Eventually I took the route of buying a wireless charger instead of waiting for parts from China. That worked for a little over a month and a half. Then it would stop charging and give me the red light of death. I would eventually be able to get it charge, but at a slow pace. I first tried with the battery, replaced it and of course it would only recharge via wireless. That worked for about 3 weeks and the problems started happening all over again. I finally got my charging board and a new battery (again just to be sure) in from China. Installed both and made sure all connections were good. In the beginning it would take a charge from a usb cable, if the phone was flat and then that stopped. If you tried to connect it to a computer, it would read "Device is requesting too much power." Wireless worked again so I went with that. Now, the phone is going back to having issues with charging in general. I refuse to give up on the phone, but I feel like I'm running out of options here. I'm running the latest PA 4.4.4 build.
Any suggestions?

USB Charging issues / Computer does not recognize while on

So this issue happened out of no where after my phone died to zero last night. I tried charging it back up but all I could get out of it was the grey charging battery but it would only stay on for 1-2 seconds shut down and reboot. Let it charging for an hour and got to about 1-2% and it would die as soon as it booted up. Factory restored to OA6 and still see the same issue. This is also the odd thing... I was able to connect it to my computer and use Oden to do the restore! After lots of troubleshooting, trying 4 chargers, I realized wireless charging still works fine. Charged it up 100% over night and wireless charging is still working fine and phone is working fine. Still cannot get USB to be recognized while on either by computer or from USB charger. With a full battery, phone off, and USB plugged in phone still flashes the grey battery icon and reboots constantly.
Only thing I can think of is I had it in my pocket after spin class for a little and moisture might have gotten in the port?
Any ideas what happened here?
Update: I ended up just buying the Nexus 6P since I'm about due for a new phone anyways.
Well just figured I would pass this along. Was bored before and looked at diagrams to fix the USB board and saw this little port in the back you can access really easy. Decided to open that up and press the connection down a little tighter (the USB board is separate from the main board). USB didn't work before doing this, then pressed it tighter plugged USB in again and it worked.

[HELP] Charging problems

In a beautiful day, when I forget my charger at school, I used my PC to charge my cellphone ( just 2 days like that) and the cellphone was detecting like usual: If connected to pc it shows charging over USB, If connected to AC it shows AC. Ok then, so What is the problem? After One week, when I was travelling using the phone as usual the battey ended and cellphone turned off at 0% (perfectly normal), as soon as I was travelling I used car charger to charge my Zenfone (It is an 2A car adapter). When I connected the cellphone (I was on Stock ROM) it take more time to detect charger than usually (like when you connect it the phone instantly shows the battery icon when off) it takes over 20s connected to charger to show the battery logo, the phone was saying that 1/4 of battery has been charged (WTF it was totally discharged from 100% to 0% and when I put 20s it charge that much? This is not possible I tought). When I turn the phone on it was showing 30% OF BATTERY, I wondered how that could happen. (I alreay saw this bug on my friend's cellphones from other brands like Samsung & Motorola). Anyway, when I saw those 30% I saw the battery graph (wich shows if is on AC or USB) and it was showing charging over USB. BUT HOW THAT COULD BE USB, ITS A FRRAKING 2A CHARGER WTF ZENFONE. I tested on my sister's phone with same cable and same charger, it was showing charging over AC as well. When I finally get home I let it charging, after 1h30m it just charged 15% with Asus AC charger & at the battery graph still showing charging over USB, when I tried to connect it to computer the phone was showing charging over USB (btw it was ok because it was on PC) but windows doesn't said nothing was connected, no USB mismatch, NOTHING. I was on panic. WTF HAPPENED TO MY CELLPHONE. This day I decided to go to Marshmallow, soon as I have root and TWRP pre-installed (when I still have usb connection {3 months ago when I made root}) So I downloade RR zips, upgraded, everythig was ok, Marshmallow Running successfully. But one thing wasn't ok, the freaking charger detect. It was still saying "over USB" but it was on AC. Tried to go o bootloader, no answers from the phone either from windows. I bought an USB-OTG adapter, not working too. I bought an new microusb sub board, replaced it to the new one. No success, still saying charging over USB, no pc connection. Just one thing chaned: OTG before SubBoard change it doesn't even gave energy to "feed" the pen drive, mouse doesn't work too. This night was when I became freaking mad, I let it charging, when I turn the phone on it has just 25%. 6h Charging and 25%. I said to myself, this couldn't be possible, no way dude. I don't know what to do anymore, I'm desperate, is the only android phone that I have, already tried many chargers, many cables, many different computers, no clue of what happened with this cellphone. So is not an hardware issue (as soon I already had this issue, but it get back to normal by itself last time, I didn't do anything) but now it has been 1 month charging "over USB with short battery life. What am I suposed to do now? I tried repair battery life PRO, app from an XDA member. It says everything OK with battery, screenshot below: (translate: No problems founded). And another screnshot of the USB problem. As you guys can see my battery graph is sh*tty, never get to 100% in one day because of this issue.
@gadmei.tw @TecnoTailsPlays (New thread that I was saying).
Please anyone help me, I don't know what to do anymore . I always helped guys with other issues on RR and other rom's issues, now please I need you guys to help me.
Sorry for my bad english, I'm from Brazil and I'm nervous now.
Thanks XDA :crying:
I half read your story .I think your battery is miscalibrated.You need root and a app to calibrate it.
Say thanks if it helped.
