Phone power downs randomly, then...

So i've recently come back again with an issue i had before with my S2 where i had an issue of it randomly shutting off then vibrate. Back then i just restock to ATT and made sure the power button wasn't stuck. It wasn't happening for a while until just yesterday. [ I did go back to Jellybean after the problem stopped happening as well]
Now currently i've restock back to ATT 2.3 /
So now im almost positive it isn't my battery because once that problem started happening [still stocked] again. Also it would randomly shut off when im and listening to music with headphones and emit a high freq. pitch and the LED camera was flashing when it vibrated as well. Its also very hard to get it back to recovery/download mode but i can and also just starting it up again with the power button and i have to also take out the battery as well .
So so far i've gone back ATT with Odin, and was wondering if someone could help me.

You restored to stock 2.3? Gingerbread? I've only experienced this when uninstalling apps on jellybean, particularly apps with root access. Will do a hot boot. Likely because the system is not mounting or unmounting properly during process. I assume. Never once have I experienced this on any ICS Rom. Try Sky ICS or Embryo 5.x.x Rom. They're both pretty stable.

Can you get me a copy of the info tag under the battery please? There was a series (which I had 3 of) that had the same hardware issue that you are experiencing. I'm not near my SR of the series, but will look when I get home and post. It is however an issue that AT&T and Samsung are aware of. AT&T gave me a GS III due to the issue.

Well that looks like it was from a different batch. Same factory but different batch. Most likely you have the same hardware issue I had. My recommendation is to contact AT&T via PHONE, not the international line. You don't want warranty dept. Tell them that you are on a Sky Rocket, and that this is your "x" one that was under warranty, and that all "x" of them have failed under the same known hardware issue. The options you will have are either get a replacement, file under any extended warranty you purchased, OR you can tell them that it is unacceptable, and you would like a different device. They cannot offer you a note, note 2 or any of the iphones. I opted for the S III, and have been happy ever since.

Just so you know it is not the best idea to post you're IMEI publicly.

man now i cant even remove it from the other users qoute, but i think i found out it is the powerbutton because when i eventual am able to boot up my phone, if i press the powerbutton to wake up it , it then a few seconds later will shut down randomly and start vibrating with either the flash or no flash at all [camera LED] also it seems like my phone was wet and the power button is not stuck because i opened up the entire phone and its still clickable with no problems.

Done did, well get a dental pick (not a tooth pick) and gently clean around the edges of the power button. When you do get it powered back up, make a backup to your sd card, JUST IN CASE you need to send it back to sammy.

I dunno if I'm having something similar happen. My phone was working completely normally (CM 10). Working this AM ok, I pull up an email, and then it shuts off, tries rebooting, the Samsung logo comes up, I get a brief flash on the screen (sometimes just a single line that varies in position on the screen) and then it keeps vibrating. Never had this happen before....and of course it happens as I am at the airport without my laptop to try and put it into download mode...I can't even get it into recovery. Ugh!
Any thoughts?

sticky power button, 1stop sticky has a few links for that problem

Or take the phone apart and clean it. Its not hard like 6 00 screws and a box cutter then its really easy to clean.

Thx. I did take it apart. Luckily I had a micro screwdriver for glasses with me, since I am out of town. Took the board off, blew into it, pressed the button a bunch, etc. Seems to be working now.
Sounds like this is not an uncommon problem though. Makes me wonder about the quality of the parts... This phone is just over a year old, and has always had a case on it (though I do keep it in a pocket so there could be some lint working its way in).
I am a novice at taking this phone apart, and I managed to do it with the following:
An old laminated Blockbuster video card
A hotel door key
A glasses flathead screwdriver.
So if you are nervous about taking it apart, don't worry... It's not hard.

[Q] Help. My tf300 is dead

1. I dropped the tablet from approximately 50cm above a hard surface.
2. Initially, I thought it was no big deal, so I proceed to try turning it on.
3. Something was odd; the tablet did not boot at all. It's NOT stuck on Asus logo. All I can see was black screen, completely unresponsive.
4. So I tried to hold power for 30sec, reset, hold reset for 30sec... nothing worked. :crying:
5. I figured, 'something must have gone wrong with the hardware when it dropped'.
6. Thus, I opened the tablet & carefully tried to find out what went wrong. (And I really hope I didn't break it even more in the process...)
7. And here I am stuck with no more idea.
WHAT I FOUND OUT:
LED indicator flashes twice when I press power or when I connect charger. Edit: It only flashes twice if I have charger connected. Nothing happens if it's disconnected from charger.
PC does not recognize tf300.
I have no warranty.
Please help me. Thank you!

Thank you. I thought about that, too. But I cannot do anything because I have no idea which connector is which...
Can you anybody tell me where the disconnection might be? (location of battery related port?)

Here is a couple of things you can do, it already does not work so what the hell, it can't get any worse. Drink two shots of Grey Goose and check out these links.

Hi guys, I am having a similar problem. My device won't turn on unless the charger is connected. The battery display says 94% but if I unplug it, it immediately shuts off. It is like using a laptop with no battery connected, being powered by the charger only. I think it might be the same case as the OP here?
Well, looking at the photo tutorial and the video, I am still unsure about the exact location of the battery connector. Could you point it out more clearly for me? My tablet is out of warranty and I'd like to give it a shot at DIY, but taking the least possible risks.
Thanks!!

It's located underneath the copper shield. You need to lift it off to see. The connector is visible in plain sight. Just follow the wires coming out of the battery. But if you're still under warranty and don't want to break the seal, you can resort to Asus customer service.

Thanks, I will take a look at it tonight as it is just outside the warranty period
Hopefully this will solve the problem. I will post back when I try.

Well I tried disconnecting and re-connecting the battery connector, but it didn't work. To make things worth, the touch screen is no longer working. I am getting desperate... Can you point me in the right direction for, at least, getting the screen to work again?

Well, don't panic just yet. Try to remember if you'd done anything (flashing, loading or playing around with software) or anything had happened (tab drop etc...) before the tab started acting up. AFAIK, the TS board doesn't fail that often, but is fragile and thus prone to physical damage, especially the connectors and cables. The least movement in the wrong direction would wreck it. Pushing the cables in at the wrong angle would bend the pins beyond repair, to give you an idea. And you should've disconnected the battery or turned the service mode switch off before even touching anything.
At this point, my guess is either the battery is dead (not charging)*, or some weird software is screwing up the reading. Apparently, the main circuitry is intact since you can turn the tab on with the charger attached. If you can access recovery, and assuming you have CWM (TWRP requires touch), you can try wiping the battery stats.
Regarding the touch screen, there are a few possibilities. Check the surface of the mainboard if there's anything that's burned. Check the cables to make sure you did not displace any of them while pulling or pushing the battery connector. If you reconnect the cable or boards make they are seated correctly. Don't pull on the amber ribbons coming out of the digitizer. Last time I checked, the green part pasted to the face of the touchscreen can detach with the force you use to peel a protective screen off your tab. I kid you not. Above all, do not force a cable in, do not snap them in. They should slide in easy if you do it at the right angle. If nothing is damaged, I wouldn't worry too much about it now.
If you have access to a keyboard, you can go into the /etc/firmware/touch/ folder to see what's in there. This only shows the correct info if you're on stock rom. Then note the model of the touchscreen printed on the white sticker on the ribbons.
Again, turn the service switch off first.
* not charging could be caused by the battery itself or the chip controlling it on the mainboard. But we want to examine the obvious first.

wow this trend really old.
...just rediscovered my old asus transformer n upgraded it android 7 and gave it to my niece...
lonq story short she dropped it. and now the device dead. I opened it and reconnected the battery and still the screen looks dead.
when I connect it to the laptop, windows detects it and even shows it's charging
... did I miss something or? everything looked connected when I opened it

Interesting problems - no wifi card detected, battery lasts 2-3 hours

Model: SM-P900
OS: 5.0.2
This is an interesting one I think...
Summary
On my Note Pro 12.2, wifi cannot be enabled - it says 'turning on... ' but never actually turns on. Also, battery life (2 different batteries now) is about 2-3 hours with no apps installed or used, even if the device is on standby or totally powered off.
Background
I bought a used SM-P900 from a local guy who gave it to me for a good price because he said the devices wireless stopped being able to connect to his wifi network at home.
I took it back to my place, did a factory reset, and lo and behold everything came up fine. I could connect to my wifi network, the device was very quick and nice to use, and the battery seemed to last a good long time. I used it for a couple of weeks without any problems at all, and then one day it started having problems with the wifi connection.
Wifi issue
The unit would connect to my wireless router, but it wouldn't actually transfer data. The download arrow would flicker, but the upload arrow would not. Every so often the device would drop connection entirely, then automatically reconnect after a few seconds. Reconnection would still have the same problems - the device appeared connected, but would not actually transfer data.
After poking around the forums I decided to do another factory reset (also tried deleting cache as well). This didn't fix the issue, though it did cause a new symptom - the wifi card could no longer be found at all.
Wifi Issue #2 - wifi stuck at 'enabling'
Factory reset number 2 resulted in the device being unable to turn on wifi at all. Going through the initial setup after the factory reset, the screen where you connect to your wifi network just showed 'Turning on... ' (I think that's the text. Device isn't in front of me at the moment).
After this, regardless of any steps I take, I cannot enable wireless (or bluetooth) at all. I move the sliders and the 'turning on...' message shows for a few minutes, then the slider automatically moves back to the grey off position.
And now the battery...
After this, I noticed the battery seemed to be discharging at an alarming rate. The top back of the device would also get unpleasantly hot, and the battery would discharge at around 30% per hour - even though I'd not installed any applications at all on it, let alone run anything. This was also after I'd put it into power saving mode.
Figuring I'd come back to it the next day, I charged it up until bedtime (charge around 95%), did a complete power off of the device, and then went to bed. 5 hours later I work up and... the device was totally dead. Could not power it on regardless of anything I tried.
Flat battery, no power on... so I replaced the battery.
I bought a new battery and installed it, and now the device powers on again. Battery discharge rate is fearsome - if I power it off completely, it loses about 25% per hour. Oddly enough, if I just have it on standby it loses slightly less - around 20% per hour. This is with no applications installed (default after reset).
Tinkering with it, installing battery / CPU / process explorer apps I cannot see anything that is using much in the way of system resources. Battery capacity doesn't seem to be being reported correctly (around 3800mah) and discharge rate seems to be between -1000 and -1200
Apps I used:
CPU-Z
CPU Monitor
GSam Battery Monitor
System Panel Lite
Note: I bought a wired USB network adapter so that I could install apps on the device, since wifi is totally broken.
Troubleshooting steps tried:
Clear Cache + factory reset = cannot enable wifi (cannot find card?). Battery run flat and died.
Factory reset (x 4 or 5) with new battery installed = no effect - battery life only 2-3 hours with no use. slightly worse when device is powered off completely.
re-install OS ( Used 5.0.2 Netherlands ROM from Sammobile + ODIN) = no change
re-install OS (Used 5.0.2 Switzerland + ODIN) = no change
downgrade OS (Used 4.4.2 United Kingdom + ODIN) = no change
upgraded OS (Used 5.0.2 Netherlands + ODIN) = no change
I cannot get the wifi to enable regardless of what I do (bluetooth is the same).
I cannot get the battery to stop discharging at a very high rate, regardless of what I do (disable all non-core processes, try and track down anything using significant system resources, etc)
I've got a bunch of replacement parts on the way from China (LCD cable, charging cable, sensor cable, etc) just on the off chance it's a hardware fault with something other then a motherboard component... but does anyone have any ideas? Anyone seen this type of thing before? Wifi cannot be enabled, very high power use even after factory reset and nothing installed?
Any help at all would be very much appreciated.
Donovan.

Just a follow up - I figure I might as well keep my troubleshooting notes here, in case they end up being useful to anyone else in the future.
I've been suspicious that the issue with the battery life is caused by the wifi card problem, rather then being a separate issue. I've tried to disable anything even vaguely related to the network in the OS, just to see if it was something constantly trying to connect or sync even though I had the wireless and bluetooth disabled, as well as airplane mode on.
Not much seemed to be having an effect, but I did notice a setting last night called 'sync'. Yes, I'm new to android...
anyway, disabling sync seemed to have a dramatic effect on the battery life. It's still discharging much faster then I'd expect, but now it looks like the battery will last around 7-8 hours instead of 2-3 hours that I'd been seeing. Also, the unit doesn't get as hot around the camera as it was before.
Note, this is with the device on standby OR powered off entirely, and no applications running and power saving mode enabled.
So back to the wireless problem.
Does anyone know where the wifi chip is on these things? It doesn't look like it's a socketed component, so I'm assuming it's soldered onto the motherboard... but I can't seem to find it.

All Samsung tablets, wifi is built on board. A factory reset won't solve the problem, you have to change main board. A used one may be around $90 on Ebay.
Quick discharge in Galaxy Note Pro and others, mostly caused by cracked battery connector. A re solder this connector will fix the problem and it takes only under 5 minutes.

Definitely sounds like a hardware issue, particularly if both batteries experienced significant drain when in full power off state. There should be practically no drain when fully powered off and even standby drain on a fresh factory reset with sync off should be minimal.

I looked over you post on this issue in another thread (http://forum.xda-developers.com/galaxy-note-pro-12/help/unstability-caused-hardware-software-t3142081) and I'll pull out my inspection and soldering gear and take a good long look tonight. I'll update this thread once I've done so. Thanks for the tip!

This is what a Samsung Repair Center will do to fix this problem:

It Works. Battery connector replaced. Smoooooth
After 2 visits to Samsung , my unit finally works fine.
Motherboard and LCD were changed first time. But issue persisted.
Second time, battery connector was replaced. Since then it has worked very very smoothly.
I doubt they actually replaced the battery connector as it takes a lot of works than just re solder the connector. Replace the connector requires the main board has to be completely removed .Re solder is simple as they only need to disconnect the battery cable and do the rework from the top of the connector.

Just a quick update. I've not had a chance to pick up some small soldering iron tips to do the resolder job, but I did take a very close look at them with a magnifying glass and they seemed fine.
Then I remembered I had a 20x loup and took another look - looked a little less fine, but reasonable. I did notice that one of the pins seemed to have a break in the solder though... which is rather odd, considering how solder flows. So I bought one of those little USB microscopes that Beut mentioned in one of his other threads and took another look. I'm still tinkering with the thing to figure out how best to use it, but I got a few pics.
The solder doesn't look all that bad... but it's definitely not perfect.
Hmm... it seems I can't post links to the pictures yet as I don't have enough posts to my name.

Trust me it looks fine but the trouble is from there, not just this tablet but others all have the same problem.
Look at the white female connector, it's also the source of problem if positive cables ( red ) and negative cables ( black ) don't make good contact
with six pins of black male connector. I see the trick of disconnect and reconnect battery cable many people do to fix intermittent power or battery quick
discharge, the problem is from loose female white battery connector.
You know how to solder so the fix is easy: put a little solder over red and black cables where they make contact with male connector.
You need a knife to cut these small plastic on the white female connector like this one:

This is an example of bad contact, the pin of male connector is between the opening of the tip of battery cable.
Look at two on the right side, two pins sit in the middle of the opening:

I'll give that a try as soon as I can get some wee little soldering iron tips. My local electronics store (Maplin) seems to be out at the moment. Hopefully I can figure something out this weekend and at least try your fixes!
Thanks again for your help!

Just exactly the same problem I have with my gtalaxy note pro 12.2 and I am looking for the solution.

I had exactly the same problem.
In the beginning, it was just a periodic disconnect.
After I have tried everything else: Factory Reset, USSD-Codes, other ROMs, Battery exchange, it got worse, so that no WiFi/BT enable was possible anymore.
When I read this thread, I started to examine the connector, I figured out, it was loose.
Then I re-soldered all the pins. But the problem got even worse. With a microscope I found out that the solder pad of PIN 3 was broken - unrepairable (because underneath the connector).
With a little speculation and a bit of courage, I guessed where this pin should continue.
I have drawn a wire between and started the pad. It had WiFi/BT from beginning and kept it stable !
I did the soldering using magnifying glasses, a 0.4 mm soldering point. But the heat is melting the plastic connector very quickly. And even very little shaking hands are too much for precise working. This is a job I cannot recommend to anyone. Will end up in more damage than repair.
The wiring was too strong and broke the part where I soldered it onto after a little bending.
I wonder, why it happens quite often, people have this problem. Maybe its a weak design which lets pin 3 broke after touching the battery connector.
Now, knowing the root cause, let me think, it was a raising connection resistance in the beginning.
(I would like to post a picture, but its not allowed to new users)

My tablet has all the exact issues. Just looking for an update from dkaaradal. Were you able to fix it??
Thanks!

White horizontal lines across the screen?

Hello,
Lately I've been noticing that after some usage my phone starts showing white horizontal lines across the screen. This happens when I touch the screen a lot in a short period of time. So for example when I swipe across the screen as fast as I can for a good 30 seconds. The picture shown doesn't really represent how well you can see it with the naked eye. It's much more noticeable in real life.
What could cause this issue? And is it a software issue or could this lead to a permanent hardware issue that needs to be fixed?
Thanks in advance!

Thanks in advance!

I suffer from the same flaw (and many others). It's more noticeable with some colors and also against darker backgrounds. Unfortunately it's a hardware problem that needs to be replaced. I guess that glass is not enough separated from the screen itself.

Hello,
Lately I've been noticing that after some usage my phone starts showing white horizontal lines across the screen. This happens when I touch the screen a lot in a short period of time. So for example when I swipe across the screen as fast as I can for a good 30 seconds. The picture shown doesn't really represent how well you can see it with the naked eye. It's much more noticeable in real life.

Nothing. It seems to be a hardware issue.
I'm now trying to send my phone back for warranty, but it seems like there's a shortage of new screens at the repair centre in The Netherlands.

I have had same problem but right now I cannot see these lines. They dissapeared, for now.

Same problem here, sometimes i can see horizontal lines on darker colors. After a lock/unlock the lines are gone.

Anybody figured out for sure what causes this or had contact with HTC repair center and got a replacement or an answer as to what's going on ?

mine has the same problem after 4 months of use - will probably call the support
did you get yours fixed?

same problem here but doesnt bother me , strange to see

here is a pic of mine - today after 4 months of use it started appearing!

Hi, I have the same issue, three days after bought the smartphone. It shows this lines 8 times for two weeks ...
Anybody sent it to support warranty?

Same issue here, just started a couple weeks ago and hasn't gone away, even after a factory reset (to get that out of the way for when I take it in to my Sprint store.) Guess I'll see what Sprint says on Tuesday °¬°

Its a weird one. I got mine a couple days ago. I saw this for a couple mins when i first played with it. Bur havent seen it aftee using for hours since. Not sure if it is completely hardware. Weird how it can come and go

O just started getting this along with my ghost touch issues. This phone is a pos. My bootloader is unlocked as well. Anyone know HTC warranty coverage after that?

when i clean my phone with a microfiber cloth and i turn on the screen, i see the lines sometimes! maybe some pressure on some site and thats because the lines appears?

It seems to be a software issue.
The lines appear sometimes without any touching of the LCD and they also go away without any touching or pressure on the LCD ( thus we can conclude that it's not the digitizer ).

I dont think so, my wife has the same phone and hers phone doesnt make it.

Mine does it too!
I made a post about it weeks ago because I had the same issue and was actually in here looking for it.
If I turn the phone upside down and wipe the whole phone I have white lines across my display.

Seems like my educated guess on it being a software issue ( bug ) and not a hardware issue ( bad application/mount of the digitizer ) was right.
Can't get these horizontal lines to appear again no matter what I do since the Oreo update on my u11.

Hi mates,
After my device have received the last update (Android Oreo 8.0) this problem disappeared. The same was happening with you?

Random shutdowns to 0% battery

Hello all
I have a G-930F running stock 7.0 Nougat and am not rooted. Recently my phone randomly shuts down and when restarted manually says the phone as 0% battery, despite the phone being on 60% before turning off. I got a 64gb micro SD card for Christmas which is the only major change I have made to my phone. Does anyone know what could be causing this/do I need to fit a new battery?
Please find attached a screenshot of my battery usage.

Could be the battery has failed, not uncommon amongst the S7's from the number of people I see complaining about the same thing
Could try clearing cache from recovery, and even a factory reset just to be sure it's not firmware related
Maybe even flash stock again with ODIN

Thanks for your response
Ive wiped the cache, if it continues will factory reset/flash stock
Might just be easier to get a new battery tbh

Probably, but would suck if you went through the whole process of heatgun removing the back of the phone, killing the IP68 waterproofing, warranty etc, just to find it still did it because of firmware
Probably is the battery though

Where are you (and your phone) when this happens?
It might be related to cold temperatures.
I had a similar issue anytime I use my phone out in the cold, the battery drops almost instantly.

I'm in London and it is quite cold, I'll take note of the temperature when/if it happens again, maybe even turn up the heating hahah
It happened today afternoon and it was very cold, and this morning where it also was quite cold so this could play a part, weird tho as I'm also in Sheffield where it is also quite cold and this problem didn't occur

I'm right on the coast of the North East UK and it's snowing and icy outside, very cold in the mornings in the house before heating comes on, and no issue with the S7 battery (My iPad screen is so cold it needs wiping before I can use it, like condensation over the screen)
Although if the battery was on it's last legs anyway, it's possible the cold could affect it in ways it wouldn't to a healthy battery

I don't know how accurate AccuBattery is in telling the health of the battery, but it is in very poor condition, I've also reformatted my sd card, and the phone has not yet restarted (fingers crossed), will probably replace the battery in the new year

I've been getting the same experience .. I live in NL and it's not that cold .. the last time it happen was just now, and it's 12 degree outside ..
I think it got something to do with the last update (that was the last major change I had) ..

So yesterday it happened again so I removed the SD card however about 2 minutes ago it happened again, so I think it is due to the battery itself, will have to replace in the new year since I made my warranty invalid by getting my screen replaced and they removed the gold sticker on the inside

I have now replaced the battery, turns out the original had swollen quite considerably, as you can hopefully see in the pictures. The battery should be as thick as the black section and the grey part entirely on the bottom face.
Will report back if random restarts/switching off still occurs

Yea that's when it starts filling with gas, the plastic casing is airtight, but the gas is flammable if it leaked, I've had an MP3 player do that and the battery swole up so much it popped the front off the MP3 player, it was almost rounded
Hopefully your problems are solved

been two days no issues so the new battery seems to have done the trick
i did tweet samsung about the swollen battery, they gave me a call but since i did the repair myself they obviously won't look into it, but didnt answer my question about whether or not this was a known issue/could it happen to other people etc

You solved it allready. ...

yesterday I received a software update for the phone ... so last night I let my phone run through the battery ... this morning I woke up and it still on with batt level around 39 percent ... before, I could never reach 50 percent .. It would go from 60 something percent than suddenly died ..
