Random Black Screen

Recently my S710 developed an annoying habit of having its screen randomly go black. It's not that the screen actually goes off, since there is still a back light and you can still see very faint image of what should be on screen if you look at it from a certain angle, but not enough for it to be useable.
It started happening after I flashed my rom to Gonzo's Mona Lisa, but I think that's more coincidence than anything else, since it happens with all the ROMs I've tried.
It's not a constant thing, either. It doesn't happen when I do anything in particular. I have noticed, weirdly, that when it does happen while I'm trying to write a text message, turning on caps makes the screen visible. As soon as I press anything else, it goes blank again. I usually just have to wait for it to return by itself. This is, as you can imagine, pretty annoying when you're trying to write messages.
I hate to think this, but reckon it's a hardware problem? I am really loathe to send it in for repair, I'm sure it will cost a fortune.

Hi i got the same trouble,
it became too anoying to use the phone
but the only solution is to bring it back to repair center because they have to change the mainboard and then you get an new IMEI number too.
hope you still have a warranty of the cellphone on it because it's almost the price of the phone if you wanna to be fixed the problem.

Have you installed Mesh?
I have noticed that this only happens when the Mesh client is running.

No dont know even "Mesh" so i m sure it was because the hardware, so decided after 2 month of having the problem to bring it back to the store and there they send it to a repair services after 4 weeks i got it back with a new front cover and new lcd module but the problem was still there and i had to wait another 4 weeks to get it back from the repair service and then like i said in my first post i got a new mainboard with a fresh new IMEI Now i m back with a new phone but i waited 8 weeks
so i dont think it's because a software . Because i tested 2 month before sending it to fix the problem (with warranty )

Hm, How long is warranty? A year? In that case, I do have a warranty. Sounds like this is gonna be a rollercoaster ride, especially considering how reluctant people in my country are to do anything without trying to make it seem like it was your fault.

If you want to take advantage of the warranty, you will have to flash back the original ROM of course.

Yes you have to restaure the original flash, and the warranty is 2 year because mine it had 1 year and 3 month old when i to it to the repair service
for the problem they can not fix it in another way i m sure of that so i guess it's not your fault at all or you have to ask a new one
hope you will go ASAP to the repair service

Oh, I have flashed back to an original HTC rom just out of curiousity that it might fix it . Thanks, I'm sure I'm on a pretty big mission here.

Slide issue & AT&T Warranty Replacement?

It seems that sometimes when I slide my Fuze back in, it'll turn off the phone and I'll need to turn it back on.
I've had the phone for under a year and to that end it's still got the AT&T warranty on it, but since I bought a Tilt 2 a week ago I'm not sure if AT&T will still accept it.
Does anyone know if they will? It'd be nice to keep the Fuze as a backup phone and I don't want it to magically get worse right as I'm out of the warranty period.
Thanks in advance!

thats wierd? they should take it back since it's under a year old. But as soon as you bought the tilt2 the insurance was transferred to it.

I don't have insurance, just a straight warranty, and I haven't called them yet so I'm not sure if it's just me being stupid or if they'd actually shoot me down.
I don't think AT&T's call center is open on Saturday which is why I haven't called them yet.

im pretty sure its open on saturdays, but thats one weird thing, sliding it back turns off the phone? thats really weird haha

I've had the same problem with two previous devices, and It's really annoying. Certain times I can slide it in and out all day long and it's fine. But when ever I'm using it for something important, like navigation it turns off when I slide out, or slide it closed.

yes if its still under warranty they will fix it

My phone is going home. :(

The power button decided it doesn't want to work anymore. Since its been rooted, and I don't trust the shops in town, it's going back to HTC for repairs. They told me it will get wiped during the service (and I will do a factory reset before it leaves), what are the chances of it coming back locked with the factory ROM installed?
Any other things, besides the S3, I should watch for when it comes back? I'm not worried about losing LeeDroid, it's all backed up, and can be restored as soon as it comes home.

Well the power button is a part of the removable SIM cover so unless it's the button in turn being pressed by that that's causing your problem then it's a very easy repair... All bets are of as to whether they'll also RUU your phone for you.

The switch itself is on the phone. Only the physically pressable part is on the SIM cover.

I don't think you will get a s3 version back given the fact that you sent out s4 version and this repair should not be so difficult that they have to give you a replacement.
But, they will very likely factory reset your phone and put everything back to "out of box status". So you will have stock Rom, locked bootloader. I learned this from other threads where people saying it is part of HTC's repair process to flash everything to factory state no matter it's hardware or software repair.

Got the quote back on the repair today.
In order to properly repair your device, the following action(s) will need to be taken which will require payment due to the out of warranty diagnosis:
• Replace Device Main Board

So, when it comes back, it will probably be locked and untampered. It's bad that the guys at T-mobile were telling me to lose it, but I wanted to take the high road and do it right. A main board is $240, btw.

So not worth it...It will be $240 + tax.
You can buy a new one locally for ~$350...Probably could sell the other sucker to some idiot desperate for a deal for $200 as well...

Did they give you any reason why exchanging the mobo is out of warranty? You should ask so if not.
I mean, you sent it in because of a defective power-on button...

They'll just say the reason why is because the HBOOT displays "unlocked".
Honestly if you want to get warranty coverage on an unlocked phone in Europe your best bet is to brick it to QHUSB_DLOAD mode and then send it in.

That was exactly the reason I got. Oh well, it's on it's way back, I can finally put the Nokia 7510 I have been using out of its misery (and mine), and have my One back. There is at least a thread now, in case someone else runs into this problem, they will know what to expect.

I took my tmobile one s back with me to taiwan and got the screen fixed there (HTC has repair/service centers there, it's kinda like an apple store without the products, all they do is help you with your phone)
Anyways, they called me and said, literally, "the mainboad is unstable and needs to be changed" (i sent it in for a cracked lcd) I declined and said just fix the screen....they ended up sending me a brand new/refurb device..

Bad Vibrate Motor?

I think my vibrate motor is either going bad or has a short, the phone will vibrate sometimes and not others, i thought it was a software problem but after a wipe and it still happening i realised if i hit the phone on its side that the vibrate will come back.
I cant find in the teardown threads where the motor is for if I took it apart. I dont have a waranty anymore cuz of my unlocked bootloader and dont wana risk getting a locked down one by the phone insurance.

I have the same issue. A quick shake and it works again. What's weird for me is it's only an issue with haptic feedback. Notification vibration always works for me.

Hey fellas. Unfortunately, it's a hardware problem. Go ahead and take it to VZW to get a replacement.
My story: the vibrate went bad on my first Razr, and they just shipped a new one to my house. I spent a good majority of my five-day time limit to return the defective one trying to remove all trace of rooting/unlocking/etc...
You may know that once you unlock the bootloader, you can never relock it. You can't unblow the fuse - believe me, I researched. I factory reset my phone, nervously gave up on the bootloader, and shipped it back. I was nervous due to not knowing how thoroughly they check for unlocked bootloaders.
It's been about a month and I haven't heard anything. No guarantee that you'll have the same luck, but there's not much you can do if you have unlocked your bootloader.
One more downside, one I didn't think of until I had already placed the order: They WILL ship you phone with software passed 9.20, meaning you cannot unlock your bootloader on your replacement Razr.
Does't matter much since you can still root it. And we're getting 4.4 sometime in the future.

Screen Failure

Wow it has been a long time XDA, how is everyone?!
Anyways...last night as I was reading a text message my screen suddenly turned off and won't turn back on. Before this the screen showed no signs of damage, no artifacts and no tinting issues. The phone has never been wet and never been dropped. It is an unlocked Snapdragon model purchased directly from Samsung the day it was released.
The screen seems to still respond to certain things:
-Battery charge sound plays when plugging the phone in
-Holding power down seems to lightly vibrate the phone
-Putting S pen back into place vibrates the phone
-Calling my phone works (ringtone plays) but nothing appears on the screen
-Randomly tapping the screen like a mad man will make the texting noise
I've tried every button combo (felt like I was playing a **** flute) and I have tried plugging it into my PC but it does not recognize it.
Anyone else hear of issues like this?
Any recommendations before it goes back to Samsung?
Thank you for your time

Try a hard reboot with the control keys.

Unfortunately nothing seems to work

Sounds DOA, sorry to hear that
Try a full charge. Pull the SD and Sim cards too.
Don't think it will help but nothing to lose.
Probably a failed soldier joint, connector or a solid state component that wasn't that solid.

I tried that as well but nothing helped. Thanks for your suggestions, I understand these things happen but I really need my phone for work.
Any idea if they will repair it or replace it?

Send it back to Samsung they'll either fully replace it or just replace the screen, one or the other but it won't make any difference the phone will still be fine after it's fixed. As long as you didn't do anything to cause it then it'll be taken care of free of charge.

You're welcome, wish I could of helped. Sounds like you tried all that could be done.
If you're stateside see if you can get it done here.
Talk to Samsung US tech support. Philippines and SK tech support suck so keep trying until you get US if stateside.
No idea what they will do... lean on them if need be.
They'll first want to inspect it most likely.
Maybe they own up to it... that's the right thing to do.
If not, teach them some lessons. The screechy wheel gets the grease. Don't settle for anything less than that phone repaired or a new one.
Let us know what happens...

Quick update
Sending the phone in was not too bad, just log in to Samsung and go to your list of products and select warranty (My 2 factor authentication was enabled and it was texting the code to my broken phone, Luckily I had a backup phone)
It will give you the option of scheduling a timeslot with a Samsung Experience store if you have one near you or mailing it in (I'm in Hawaii and there are no Samsung Experience stores here so I had to mail it)
They pay for postage just make sure to follow the instructions (They ask you to disable some sort of Google security thing before sending it in and to include the power cable and charging brick)
Print out the label they provide to you then pack up your items nicely and drop it off to UPS
I'll continue to update for those who may have the same issue or for those who need to send their phone in.

Yea. But what do you do when they claim your service has been received in destroyed condition and such. I've dealt with Samsung here in the US several times and honestly scared to ever send them anything again. The stress. The chats. The whole ordeal was nearly life changing

Just my experience. But it happened. It sucks majorly.

Just a quick update.
I sent the phone out on the 16th, it took 3 days to get from Hawaii to Texas.
On the 20th it was inspected and repaired (LCD issue) I am expecting the phone to be back in my hands on Friday the 23rd.
Samsung didn't ask me anything nor did they give me any issues.
When the phone returns I will take a closer look and let you guys know.

I'm sorry that happened to you.
I just received my phone in the mail. Everything seems to be working fine.
Apparently they had to switch out the screen and the bottom firing speaker.
I'll post some pictures the next chance I get, now I just need to reapply a screen protector and I'll be good to go.

Yay

Awesome mate
