[Q] HELP!!!!! TMobile No Help

Basically whats happening. Me and my wife have exchanged both of our Vibrants through T-Mobile 3 times due to overheating and the proximity sensor acting up. My wife literally burned her hand this morning when she grabbed her vibrant off of the charger. We only replaced the phones yesterday and are already getting the same issue. I called T-Mobile and they said they can either give me another Vibrant or exchange my phone for the original Motorola Cliq or the Blackberry 9700. When I was with AT&T they gave us the option to select another phone within the same price bracket of what our phones were worth. I paid full price for both vibrants. Do I have any options or should I work through the BBB to solve this?

Tell t-mobile that you are ready to file with the BBB, see what they do, if it comes to the worst, actually file a claim or complaint and hope for the best. Good luck mate !

you need to get out of 1st line support. You can easily get the email address to the executives of Tmobile easily. And write them a professional email stating your case and you will be taken care of.
My brother did this a few times to get out of contracts, to get a free phone and to get out of a ETF. It is effective.

So you're saying that all SIX of the Vibrants you've owned have had the same issues? Either you are the unluckiest people to walk the Earth, or your expectations are beyond reason.

I mean, LITERALLY burnt her hand? That's lawsuit worthy if you have hospital bills bud. I think you're overreacting, get a battery app and see how hot its getting. It should only get abnormally hot under heavy use while charging, like tethering or something. I mean, 6 vibrants? You expect them to keep sending them to you on demand? Obviously they're trying to stop you having to exchange your phone so often, not screw you over. But yes, use one of the above methods.

Crazy thought, but maybe it is the batteries and not the phones?? How about Tmobile replaces both batteries?

My thoughts exactly, especially since this is not a known problem with the phones. In fact this is the first time I think I've ever heard of it happening with the galaxy S line in general.

Actually it takes a fair amount of heat to damage tissue. I expect that plastic would be melting around that point.

Have you talked to tech support or just customer service?

the only time ive heard of anything like this is with cheap chinese knock off batteries. did you buy a pair of high cap batteries and a charging station on ebay or something? If so consider putting stock batteries back in cause every replacement you get is a manufacturer refurb meaning they have been fixed and tesed to be running. I have 4 Vibrants on my T-Mo plan and none have had any issues, minus the first set being hardware locked but that was a long time ago.

Lol six phones.... only in America

Now this is interesting. I actually had this happen Saturday, my story is that the wife was doing the updates and things, it froze as usual so instead of messing with it then, I told her to put it on charge and let it go (We didnt have time to screw with it then). Later on, she took it off charge, it burned her hand and she dropped the phone (Not really burned, but more of a shock it was so hot). The screen cracked, I called tmo and was told in a rude way that it was samsung's problem, not theirs and that they didn't care. I had to do a warranty exchange on it due to it being damaged at that point.. I told them it wouldn't have been damaged had it not been so hot.. blah blah, again, it was like talking to the wall.

I like to trust people on here, but when i hear SIX phones have the same problem.... I know it is NOT the phone.
same battery in each phone?
what apps are running?

A friend of mine experienced this but it was not due to the phone but the fact he was using some non-OEM extended batteries that were overheating instead. Once he went back to using OEM battery, it's been fine ever since.
The only reason he went with the extended battery is because of the unsatisfactory battery life. After getting him setup on Bionix and reconditioning his battery, he's no longer complaining about battery life.
If this is case with the OP, I actually feel sorry for TMO / Samsung. So much waste in hardware, time, etc.

Are you using a crappy ebay charger?

That's reminds me...
I've seen "crappy" chargers that don't seem to stop charging after the phone is at 100%. So, it just keeps charging until unplugged. That can't be good...
I've also seen so-called generic micro-usb "quick chargers" that claim to charge the battery up to 50% faster. Even if it's not a "crappy" charger I imagine doing so might make the battery unnecessarily hot as result of the increased speed of the charge.

The fact is that it wasnt abnormally hot. it just surprised his wife. I've touched cold things and twitched because I thought they were hot.

Yes the battery/charger may be the problem
I have had this problem on my HD2 But..... it was a result of an aftermarket battery. The probability of 6 phones having the same internal problem....is like winning the lottery, so I'd be looking to the charger and battery as the issue.
FYI, for temperature reference hot water in commercial building is usually set @ 112-120 f unless it is a building for kids then set @ 108 max. At 120 to get a real 2nd degree burn you would need your hand in it for 15-30 sec. depending on the person.
Most plastics we use in building phones, electronics and consumer goods range resisting deformation until 150-180 degrees but with a protracted long heat source can become malleable 125degree depending on the plastic.
Anyway some trivia for reference. I'd would look to the battery

My first phone died due to overheating. But this was from using a car charger that was not meant for the exact phone model.
I picked up a $0.98 charger from amazon and no more overheating issues when charging in my car. When you charge with the wrong charger it will heat near 120 degrees.

[Q] Samsung Galaxy S Vibrant Dies.....Overheated...

I am new here but just wanted to know if anyone else has had issues with their Samsung Vibrant overheating???? I have had this phone for less than 2 months from my carrier and now it is dead and in for repair!! I went to go grab the phone and the screen did not come on; however, the buttons at the bottom were lit up so i tried the buttons on the side of the phone (on/off switch) still nothing. The top half of my phone (not where the battery is) got so hot that it burnt my hand. Then I noticed blue, red, green pixel stars on the screen (which by the way burnt the screen). I don't know if it is a faulty battery/charger? Or what. When I spoke to my carrier, they told me that this is the first they have heard about anything like my case. It has been in the shop for more than 1 month now and I am getting very annoyed..as they gave me a loaner Galaxy to use and I HATE IT!!! Anyone have any suggestions??? I did not game on this phone or anything...
Thanks so much,
Pam

Happened to an HTC Aria I had, and had to get a new replacement to AT&T. The digitizer went (burnt?) out, and since it's a touchscreen only phone it became unusable because I couldn't really do anything on it.
What kind of charger did you use? Especially car charger...

I have never had it on with a car charger. I have heard that one should put the phone on plane mode as the green charge battery light will not come on. From what I hear they are replacing the screen (which they have no choice as it is burnt) as well as the board. Why is it taking soooooooooooo long? I usually have it on WiFi all the time; however, this should not do anything. It makes me mad....I have waited for this phone to come out and when I got it, I thought there was no other...until this happened. I did notice it acting kinda slow and I realize some phones do get warm...but should NEVER get hot enough to burn one's hand!!!!

I'm guessing you didn't OC the phone or anything.
Yea, I keep mine on WiFi basically 80% of the time, but the phone (in stock form) turns that off when the phone sleeps. I have brightness set to auto.
I notice my phone gets very hot when I have it on a car charger, and I'm using a charger from T-Mobile. It doesn't happen when I have it charging from an outlet in the wall through a USB Extended cable.
That's the only time I notice my phone getting hot.
Also, using the phone on WiFi tends to keep the phone cooler than using it on a data connection - I've noticed that for a few phones I've owned.
The overheating issue was also a big problem with HTC HD2s (except those phones would just go into a reboot loop/lock up, instead of burning up ).

No I did not overcharge the phone; however, I do notice that the battery life is almost nil on this phone. Full charge does not last 2 long on the phone and I only use it basically to text my daughters...and a little texam holden lol. But I have noticed with this galaxy (the loaner phone) the battery stays good for 2 - 3 days! Although I really hate this phone so I do not use that much! How would they be able to tell if it is the battery?? From what they have told me, they are only replacing the screen and the board....Well something made it go hot!! Battery or charger...When I took the phone back to Aliant I was going to give them everything including the charger, but they just sent it away with the battery. How do they know it was not the charger?? Getting very frustrated....I have always owned a Samsung phone and have never had any issues until this phone....makes me want to go back....but I do like the Vibrant when it was working....esp the screen.....

Only things I've ever come across that have made a Vibrant overheat is using cheap non-oem extended batteries, overclocking the CPU / GPU or leaving it a car in a 120+ climate then expecting to make heavy of use it without allowing it to cool down first.

I have never replaced the battery...it is brand new (less than 2 months old)....Thank god I had insurance on it... One would think that it would not take this long to come back from being fixed!!! Have never left in car....don't have to worry about the 120 degrees we are INTO snow now!! LOL... I am disappointed with Samsung. How can they tell what made it go that way?? Battery? Home Charger? They should replace the battery in my opinion as well!!

How often does the Vibrant overheat? Is this a common issue?

not sure.....it only took one time for me that fried the phone...Now they are supposedly replacing the screenh (they have to it burnt an image on it) as well as the board.

I have never heard of this happening with the vibrant. They claim they have not heard of this issue??!! I cannot believe this. I would like to know what caused this. I thought perhaps it was the WiFi being on all the time, but I do not think this is why. I do not game on it....I do not overcharge it (only charge it via home charger when it shows battery getting low - which might i add says it is almost drained at mid day??!)

Seriously, I have never heard of a phone overheating. I mean, sure they get hot when talking on it, but never overheat.

my phone has gotten really hot gaming on it while charging (stock charger and moto cliq charger), but it's never died or even decreased performance from it. even when oc'd.

Mine has gotten warm twice: once, I left Google Maps w/ GPS open when I put the phone in my pocket, and didn't realize it until I felt the heat in my pocket; the other time, I left ScummVM running (which apparently doesn't suspend properly), draining my battery over about two hours, again in my pocket.
Both times the phone was only warm to the touch. Nothing like you've described.

So do you have T-Mobile or Bell? If you have Bell (sounds like you do, I'm 99% positive) this is limited to the Bell i9000m Vibrant and not the T-Mobile T959 Vibrant.

There are threas on T-Mobile's official Vibrant forum about this issue.

My vibrant gets very very hot from time to time. I keep it on a usb hooked up to my computer at work with wifi on all day. Sometimes it will get super hot and not want to charge. I restart the phone and it usually fixes the problem. But its not the battery that gets hot, its for sure the yup part of the phone.

Sounds to me like you had a bad battery...this can cause the battery to overheat while charging. I work in construction and when the batteries on my power tools fail you can cook an egg on them when they are charging.

Did u happen to have anytype of case on your vibrant. I notuced when I charge my phone with the case on it got prety hot. Not to where it would burn my hand, but hotter than I really thought my phone should be while charging. So I take the case off when I put it on the charger.

Focus over heating

No one has brought this issue up as far as I know but I am on my 2nd Focus and 2nd battery and having what i believe to be heat related lock ups.
I reformatted tried with fresh phone not even signed into a Live ID and I can duplicate this issue about 90% of the time. I make a phone call and stuff it in my shirt pocket with a jacket on. It will lock up with the Samsung Logo and be hot to the touch. A battery pull is needed to reset and the battery is extremely hot. When I reboot the battery life is drastically diminished.
I am not using an SD card and replicated the issue with or without apps. The only way I can keep it from locking up is on my hip in a case. I can only imagine how the summer will be if I am having the problems now in the winter.
ps I kept my Touch Pro 2 and currently My Moto Droid in my pocket without issue.

Bizarre. I've never experienced that issue before. My Focus usually stays pretty cold actually.
Maybe yours is defective? It's possible.

No issues with the phone getting hot, or even warm, for me.

2 phones and batteries. I thought I would just put it out there to see if others were having issues.

I've noticed my phone getting a little warm while playing Crackdown but it never got slow or locked up ever.

When I download many songs from Zune or play a long game it gets pretty warm but it has never been "to hot" to hold and never crashed.

I also had this problem, i just had this happen for the first time today. I was using my phone earlier in the day, all of a sudden I felt it getting warm in my pocket. After I pulled it out, it was stuck on the samsung logo and warm to the touch. Pulling the battery and resetting does nothing. I keeps booting to the Samsung logo and never proceeds further. I have even left it off for a few hours and attempted to power it up again: still no luck.
I am unable to hard reset the phone.
I called my local AT&T store before they closed, they agreed to replace it tomorrow :-\

I am having so much buyers remorse. I would have returned it but it happened on my 31st day. I went through 2 phones and batteries and I still get the problem. If I talk on the phone or surf the net and stick it in my pocket the phone is toast until I realize it and do a battery pull. If I wait too long the battery is pretty much drained.
I don't ever think I will buy a Samsung again. WM7 is lacking but I knew what I was getting into but from the memory card debacle and the Samsung Boot menu the phone is crap. Hell we can't even set it down flat on a surface and use the tough screen properly. Beautiful screen but all other hardware is crap.

I also noticed a pretty hot Samsung Focus in my pocket today. After turning off wireless search it got cold again.

I have experinced the heating up issue. It happens a few times a week. I kind of think it could potentially be dangerous because of the battery. Samsung should have a recall or fix for free.

If they start blowing up they might issue a recall, but until bodily injury (and getting sued for real bucks) is on the table it is probably cheaper for them to replace or fix them.
Samsung got a ton of bad press for the GPS woes in the Galaxy S line of phones and didn't do a thing about it.
The SD card thing is weird. MS could have revoked their Windows Phone 7 compatible seal of approval but didn't probably bc it was a launch device and didn't want to piss off Samsung. Rediculous.
MS and Intel went through the same thing with the 'Vista Certified' thing. They let big names do what they want because either way they are getting paid for the licences.

my focus got warm when playing Need 4 Speed Undercover from start to finish in 1 sitting lol but my Nexus One,Palm Pre,and iphone would get hot after playing for that amount of time too. It just depends on what u are doing and how long u are doing it imo.

I did make 1 hour call on my Focus and it doesnot seem overheating...
Alson runed the Harvest for harvest and it was fine...

Random shutdowns and reboots- who has had them?

I have bought two used G3's now and both had to be returned due to the same problem: fairly frequent random shutdowns and reboots.
I have rad that this is quite a common problem and may be due to tbe battery, however no solution seems to be a 100% fix.
I'm now considering whether to bother trying to get a third replacement: perhaps all G3s will suffer from this major problem. Aside frkm this major issue the phone is awesome and perfectly priced.
So, how common actually is this problem? Who else has had it?
Could you all perhaps post the date of manufacturing of your battery, and anything you have found that solves / helps the issue.

My old(stock) battery was made in 2014 (i don't remember the date).I couldn't use the device without the charger because it would go on bootloop.
Bought a new battery(made on 2016) and everything got solved.

I purchased an extra battery and a cradle in Aug2014 and had no issues until this summer when my phone would bootloop ocassionally with one of the batteries, and then eventually it wouldn't boot at all and just bootlooped. So I bought another from LG for $15( http://www.lg.com/us/cell-phone-batteries ) and all is well. The date code on the working old one is 6/9/2014 and the new one is 8/22/2016; the one that died & I replaced was also 6/9/2014. LG batteries die a strange, and sometimes sudden death that can make it look like the phone is messed up. Most phones give you a warning - faster dissipation, faster charge time - but not so much on the G3...just random death at random battery %, bootloop, and all kinds of weirdness.

I bought a new battery (made in 2016, old one was from 2014) and i havent seen any random restarts when the phone is bellow 15%. Also noticed that my battery lasts alot more.

Mine is definitely battery related. I bought 2 spare batteries (LG branded one, but from ebay) and one causes my G3 to reboot often. The other one doesn't at all.

I'm getting this a lot lately, have never replaced the battery since getting the phone roughly two years ago. Good to know that others have replaced the battery and it has resolved the problem.

The OEM batteries last about 1-2 years for us before they start causing reboots. But that was easy to diagnose.
The real reboot/shutdown culprit for us was overheating. The heat dissipation is poor in the G3's design. Using a thermal pad on the SoC was a 100% fix for our 2 G3's. It dropped the SoC temp 10-15 C, and we haven't had a prob since. Easy and cheap.

There is actually a thread on using thermal paste for this, but I strongly recommend using a pad, due to the expansion of paste after it heats. I'll give you a quick guide here and for others in this thread.
To start you will need a kit like this if you don't have one already. They are handy to have anyways because a kit like that can open most modern small gadgets.
Then you'll need the thermal pad. For a perfect fit, I would use a 15x15x0.5mm non-metallic pad like this. You don't have to get that one, it's just an example. You could also get a larger one with the same 0.5mm thickness, and just cut it down to 15x15mm.
Use this video to disassemble the G3. It's the best one I have found so far. Of course, you don't have to disassemble it all the way like in the video. Just enough to expose the SoC chip (the biggest and most obvious chip on the board, you can't miss it).
Things I recommend when applying the pad, but not required:
- Perform the install in a clean, static-free environment.
- Be delicate when removing the ribbon cables. The tool kit mentioned above makes this 100% easier.
- Before applying, clean both the surface of the SoC and the surface of the metal phone frame indent where the other side of the pad will make contact with alcohol or something similar.
- When reassembling, tighten all screws as much as you can without stripping them. This ensures the gps/wifi/radio contacts are good.
My GF and I have been using this thermal pad mod for over 2 years now on our LS990s with no problems. I used 6wmk pads on both. Others have reported wifi/gps reception problems, but I found this resulted from using too thick of a thermal pad (1mm thick or more), or using paste.
Hope that helps! Good luck!

Had them when I got my (used) LGG3 in 8/15..
Replaced the SD card and retflashed to stock.
No problems since.
Most stable phone I've ever owned by far (JB'd iPhone 5 rebooted waayy too many times f.e.)

Either a dying battery or the infamous connectors issue with LG manufactured phones.
If the latter, please refer to @AlwaysLucky guide or something similar.

Solution on Overheat and Reboots
Hey everyone!!!
My Device (An T-Mobile D851) has Rebooting issues and Screen Dying before (Even with a pair on new batterys)... So, I made an Guide to resolve this problem, related on overheat in the SoC.
Here´s the link:
https://forum.xda-developers.com/lg-g3/general/guide-fix-display-flickering-overheat-t3563068

I bought a new battery which claimed to be new and genuine, but when I tried it in my phone I straight away got the instant shut downs. At first I thought that It must be the phone and not the battery, but today I tested it by having my old battery in which was currently causing no shutdowns, then i put the 'new' battery in and I got the shut downs again, then I put my old battery in and the shut downs stopped.
The issue seems to relate to how long the battery has been without mains charge, rather than the level of the battery.
e.g. If the battery has been off charge for 11+ hours but is on 70% I might still get the shutdowns, or if it's been off charge for -5 hours but is 20% battery I won't get them.
My big problem right now is finding a place in the UK to buy a genuine new LG battery, or possibly an Anker one.
Any ideas anyone? LG UK doesn't seem to stock them like they do in the US. Amazon sellers are a lottery, and eBay is like the wild west!

Sorry, it's a mystery to me. This is why I'm rather dubious of claims that this is solely a battery problem.

I bought another brand new battery and I still get the problem.
I have tried multiple things:
- Safe mode
- Deactivating battery optimization
- turning off background sync and backup
- turning off wifi and data
- rooting
- uninstalling apps
This seems to be related to how long the phone has been off charge for, but it definitely ISN'T a battery problem: I've tried 3 different phones and 6 different batteries and they have all had the same problem.
The only thing I can think it must be is either a problem with the charger giving incorrect voltage /current or some kind of circuitry or module that degrades/ corrupts between charges.
I don't have an original LG G3 charger of 1.8A, so I'm using a 2.0A one. Perhaps that's the problem.
Having never had a phone that has once rebooted previous to the several G3s I've now had I'm at the point where I'll get rid of this manufactured broken phone and never buy LG again.
Anyone have any good suggestions for a similar spec / priced phone (used). I've already tried a Xperia Z2 but the camera was absolutely dreadful!

I had this problem recently in which I had to change the battery and all is well but sadly, my phone's bezel got cracked spontaneously, but this time. It is at the IR sensor, so LG DO have quality control issues, but first things first - buy an OEM battery - they can be had for £5 at least on eBay.
Speaking of chargers, I had an LG charger that came with the LG G3 I bought, but that died. Fu©king Korean piece of $hit.

Horribly Overheating S4 - Over 80'oC Celsius !! (I9505)

Hey guys,
I have a first gen S4 that i purchaesed 3 days after realese.
Ever since I've had my screen and charge port replaced on my S4 it is having a horrible overheating problem with minium use. So replaced it with another new screen again, thinking it was faulty.
That did nothing so I purchased a new battry as it was getting old but nope still nothing.
I ran a full restore and update to 5.0.1 (Final OTA?) And made sure all software is upto date but it keeps on overheating and shutting down all apps.
Today is a cold cluoudy day with the outside temp being 16oC Celsius and fairly chilli and running SatNav/GPS only with no background apps still overheat's the phone.
The only way to make sure it don't happen is buy putting the aircon on to full blast !!! Which is driving me crazy as it's freezing outside.
I've read now that the first gen S4''s had a possible defect that causes this. Any sugesstons?
Thanks

Hi,
Only thing i can think of is disabling NFC and removing your phone from the charger when it is fully charged. Only had problems with overheating while doing the opposite from what i mentioned. Replacing the battery recently (It was 5 years old) solved the overheating issue for me, since i do not have to charge it all the time anymore.
You could install a new mainboard, but i reckon it would be cheaper to just upgrade to a new model.

SOLVED!
Just an update regarding this. I have solved the problem.
It was the screen replacement after all! It was a FAKE! A poorly made one at that. I got lucky a few months back trawling through hundreds of posts from years ago when someone mentioned right after he replaced his screen with a cheap one off ebay, the phone went crazy hot and would shutdown.
Hoping this was the problem I purchased an OEM screen from a distributor, I got lucky as they where getting rid of old stock and I got it for cheaper then the fake stuff on ebay, and what do you know, it worked!
So guys, if you replace your screen and your phone starts overheating like crazy, then you definitely have a low quality fake thats causing it, that is 100% confirmed!
Hope this helps!
