Phone Keeps Switching Off, Samsung Galaxy W I8150

Hi,
I have a strange problem with this phone..I've had it for more than a month but recently it randomly shutdowns itself when inside my pocket or out, even it its fully charged and on standby... it doesnt reboot so i have to manually turn it on..
It happens once or twice a day?? Does anyone else have this problem?
If so how do I cure it?
P.s. My phone is not flashed or rooted,
Thanks

FW Version ? Best to update OTA...

You can soft reset you phone, any application might be conflicting ,,, if it doesn't resolve your problem then take care about the POWER button , it might be pressed when its in your pocket and the long press will result in Shutdown and Restart of phone.
Also check your battery terminals, they should not be loose.

My damn Galaxy W was doing that too. Sent it away twice and have a replacement. Guess what? its still doing it!

Its most likely a battery issue, make sure your battery isn't fat. If it is it might be the culprit.
Or else some application inside is conflicting, like the developer did not test the app good enough then released it.

Have had 2 W's in the family doing this ,as above one went back to Samsung under warranty and that stll did it . I have just updated to CM9 - I am hoping this will cure - early signs are good

It should be, no offence to any JB fans out there, but CM9 is certainly winning in terms of stability. Do give me feedback.

This is usually the problem most of the time, check your battery, replace as necessary..

Help!

Hey, My phone is having the same problem, except that it never shuts down when i'm not using it. If it's plugged in, it's fine. If it's running an application (while not charging), it shuts off. I've had this phone for around 2 and a half years and this problem is just starting now.

Screen fades to black/Flickering (Issue)

Sorry if this has been posted somewhere but i haven't found it. Has anyone had this issue where your phone turns on and it just fades to black? I've found a few people online have this problem. I had to send my phone back and just got a replacement yesterday. It seemed to work fine for a few hours. Then i went ahead and rooted it and the problem came back to this new model they sent me. I wonder if it's a DPI or motherboard issue when you root. I have read that it is a batter issue. Another person says it's the motherboard. And another even says it's the screen that need replacing.
Here are a few videos:

Mothernoard and LCD. I'm guarantee this for You. I had the same problem with lcd, but it was broken. But i had almost the same symptoms mate. So, probably you'd buy a secondhand G3. Maybe ... I dunno right now how much will cost you a new mother board with the LCD. I'm really sorry mate ? ? Take care ??

Thanks but I'm still under warranty for 2 years with my company so they will just send me a new one. Hope the third one won't have the same problem

i hope so too

Hey, I had a similar issue then I disassembled the device and checked the connectors, board and other components, then I procceded to only reassemble the device and it now works perfectly! I believe it was bad connection maybe caused by dropping (guilty lol)

Hi
finally I found the perfect solution for this issue,
No need to call LG company
No need to replace any part of your smartphone
No need to pay for anything
this is a software issue believe me or Not !! it's not about any piece of hardware ........... yeh it's look like a hardware issue but it's not
I have an LG G3 and I was have Exactly the same problem .
All what you have to do is :
* 1 Root your phone [ be careful in this step ] .
* 2 Install TWRP recovery mode
* 3 use TWRP recovery mode to install CloudyG3 2.5.
That's all and your smart phone will be look like LG G4 , fast,smooth, and New

I find this implausible. It is most certainly a hardware issue. Software cannot fix a physical hardware (overheating) problem, although it can manage power more efficiently.
What tests did you perform before and after in order to fix the problem on the device to which you refer?

If it's not software related then it is probably a ribbon cable/connector issue...which would help explain why people are seeing recurring failures after replacing LCD's and motherboards.
I followed this youtube video and it fixed my friend's flickering LCD...it took about 15 minutes total and cost $0... http://forum.xda-developers.com/verizon-lg-g3/help/lg-g3-screen-fading-flickering-fix-t3326092
If it doesn't work the 1st time you may have to add some thickness to whatever you put on top of the camera connector. I just used a rolled up label from work and stuck it on top of the camera connector, reassembled the phone, and it's been working fine for about 3 weeks now.
Good luck

Solution for fading and flickering
I found a Solution for the flickerinv issue, you don't have to put something between the cam connector and the case.
1. Open the phone
2. Remove Motherboard
3. Search for a hairdryer
4. Blow hot air on the whole Motherboard until it heats up and you can't touch it.
5. There's a chip which doesn't sit on the Motherboard correctly, heating up fix this.
I don't take any response for demaged Motherbard or so on.
Sry for grammatical mistakes, I'm a german guy. :*

I spent days of googling and there are only temporary solutions for this problem.
After testing my phone for 2 days in different conditions I realised that the screen is going crazy when the light is changing too much.
If you do a sensor calibration everything will go back to normal:
-enter in Hidden Menu (model dependent)
-select Device Test
-select MT
-OK to restart the device
-OK and do not touch the screen for few seconds
-go to Individual Items+Power (you must push power button when you select this item)
-select Sensor Test and take care to not block the proximity sensor when you make the selection
-you will be instructed to cover the sensor (usuallyy twice)
-go down to Backto the Main List
-select Normal Boot+power (again you must push the power button to make the selection)
The phone will be restarted and you will have a working phone (I have 8 days without any screen issue)

So, let me get this straight,
The problem with the G3's screen fading is a hardware issue related to the CPU/GPU. The fact that someone puts a paper on the camera connector and it works is due to the fact that the tension applied to the motherboard flexes it and it makes the BGA balls re-connect. The only way to fix it is to heat it up gradually ( I've used a professional Bosch Hot Air gun and some special paste ) and before reassebly, to put a metal plate with some thermal paste between the CPU and the metal case. This way the CPU won't overheat that bad, and it will be pressed into the motherboard, minimising the risk of this to reappear.
For any other questions contact me anytime.

Thank you for your instructions - surprisingly it worked. You missed a step - the menu should be ELT test after getting into hidden menu.

Did this and now have an insecure boot error, going to give a fresh kdz install a go

I followed the baking instructions and the phone seems to be working again. At 375F (solder melting point) for 7 minutes. Then I let it cool in the oven for 30 minutes before reassembling the phone. Seems to be working.

Maybe, Maybe not
I started messing around with the settings, and since my phone, right now, doesn't have service, I turned data off. Where the screen would eventually fade to black, and became unresponsive, It would darken a little bit, then snap back. I said hey, why don't I get a cpu app(I used setcpu). I lowered the speed to a little over 1900, made sure it was using ondemand(using noop), turned off automatic brightness(set it to 61%), and rebooted. So far no flickering, fade to black, unresponsive touchscreen, with no touch, installed greenify. I'm gonna let it charge, and see about the battery life(thank goodness I installed greenify). Yes the phone's rooted, and twrp is installed, and xposed is in, but never changed roms, just stock. When I get a carrier for it, and it does it again, then there maybe something there.

Hi all,
I had issues after I acedentilly fried mine using maps, spotify and wireless charging when driving with it in direct sunlight. I didn't realise until I nearly burnt myself picking it up. A few hours later it started flickering and fading off suggesting to is an issue either caused or effected by overheating.
Anyway i took it apart and baked the motherboard at 175C for 8 minutesminutes and it worked flawlessly for 3 weeks until it overheated agian. Did it at 200C for 9 minutes this time and its fine, see how it lasts and maybe get some thermal paste and make some adjustments to keep it cool

Getting trolled by screen

2 days ago I woke up to this seemingly broken screen (pic attached), it was responsive but the colors and line are all over the place!...
I kept the phone untouched until I find out what is going on and get a screen replacement, today I just opened the phone and everything is back to normal like it never happened!, what is this and is there a risk of it happening again?

I have the same problem and it's insane.
Do you do a reset or something?. I'm think its a sw related issue with gpu processing but im just guessing.
Thx!

It feels like a refresh rate problem, yet it doesn't feel like a software made one...
I don't know, it seems hardware

Yes! that's what i discovered now, i went to recovery mode (Power Button+Vol down button) and i was so suprised that it lasted 2 hours now without shutting down or fading to darkness
Now i'm confused, if it was a hardware problem then we will face the same problem but i'm not sure if it's the motherboard

You have to stress the phone to see if it is stable. Recovery is a low resource environment, boot into Android and then see it is not working. Trust me, i have a device with the same symptoms and fixed it by baking the motherboard in an oven.

Half the Screen Freezes

Last night I got a weird problem, half of the screen stops. Hard to explain but made a video.
Rebooting doesn't help, even the razer boot screen does it too during boot up.
Any help would be appreciated.

Thank you. I had trouble finding the page cos half the screen had frozen again.
Looks like I might be in luck as I went into 3 store and they will exchange it tomorrow when they get more in stock.
Is there anything that triggers this issue or is it just random?

Not really sure. Someone said that if you press on each end of the screen it fixes it for a couple seconds or triggers it. seems to be a hardware defect.

Yeah, just get it swapped out.
