please help. white screen problem!

hey all i am currently having a problem with me htc s621.
when my phone is on it randomly turns to a white screen after a 2 day period or so. and after a while of turning off phone/taking out battery/taking out sim card and doing this a lot it goes back to normal. im getting pretty mad and was wondering if i need to get my phone replaced or what.
any advice is helpfull. and the phone is not updated to 6.1 or anything like that. btw it all started to happen after i dropped my phone one time. i am not sure if that helps or not.
thanks in advance

The phone may be damaged. Is it a stock phone or has it be flashed with a rom?

it is purely stock no upgrades at all. today it did something new, it was white then 20 min later wen back to normal without me turning it off or anything. should i bring it in into warintee or anything i can do to help it?

I have seen simular situations before. It is possible that when you dropped it, the ribbon cable connecting the LCD to the board became dislodged and is only making a partial connection. Or the LCD is just plain broken and needs to be replaced. You can get a new LCD on ebay for around $30 USD and do it yourself or take it to a repair shop and have then look at it for you.

i believe i will take it into the store tommorow. get a professional statement and opinion to see what i should do. thanks alot guys

I recall reading some time back concering the cause of the white screen had something to do with the backlight time, try making some adjustments with the backlight. Also do a serious search for that old thread dealing with this problem..............!

You would probably need a new screen and the best option would be to replace it yourself because you could find a cheap one off ebay and then just youtube and you could find on how to install the new screen.

[Q] My glide is screwed after wifi download overnight

Hola, noob here with a problem.
My rogers captivate glide was behaving perfectly fine one night when I decided to download some large files over wifi. It was also plugged in for charging and I was using some app (forgot the name) to prevent my screen from turning off so I won't lose my wifi connection. I left it like that and went to sleep. Upon waking up, my phone was hotttt , the screen still on but it has faded into a greenish color with scan lines. It was unresponsive and I had to pull the battery. Ever since then, my phone would last no more than a few minutes before freezing and fading into scan lines. I thought it was a battery issue, so I got new batteries but that didn't help one bit. I even flashed the kernel and still no help. I did resets, recovery, wiped caches, took out sd card and sims, stock builts. Nothing worked. I can't connect the phone to the computer or wall charger either. The screen would instantly freeze and fades out upon plugging in the micro usb cord.
Have anyone had similar problems? Did I fried the soc? I don't think it's a problem with the screen since it was perfectly responsive the few minutes it worked. This noob needs helppp.
I've posted a video on youtube but I couldn't link to it, but if you search "captivate glide problem" you'll see a video showing the freezing problem I have. I'm from the US also, so I don't know if I could get samsung to fix it through warranty since the phone is Canadian.

Well I downloaded Modern Combat 3 and that was like about 1Gb and the screen turn off because I didn't touch it while it downloaded, and wifi kept going so I'm not sure why it didn't stay on for you

Idk about the phone so much , but i am computer technician and it sounds like you overheated it, what we might call "burned it up".
The screen symptoms you have described are a dead giveaway, especially the lines
If this was a laptop, I would be sending it off for a reflow .
Typically, the circuit board gets so hot, the solder on the ships melts enough for a tiny bit of separation. This requires a "reflow ", where specialized equipment is used to repair the solder connections.
First, you should to a factory reset , then try to do a warranty claim. (unless u have insurance from your cellular provider, then u might check with that)
*edit, sorry, I missed the warranty part the first time I read ur post*
The next option would be to check with the guys at www.mylaptopisbroke.com
Email them, ask if they concur with my diagnosis and if they can help.
I have been dealing with them for about two years and always been highly satisfied. (They are in NY, I am in TN. I have sent literally dozens of devices to them)
If none of those 3 options work out for you, start looking for a new phone.
Sorry :-/

Sorry, but I agree with the previous poster, sounds like a hardware issue. Start the warranty process, can't know if it's gonna work til you try it.
Not to try to close the barn door after the horses have bolted, but in case you get into a similar situation with your new phone, there's an easier and safer way. When you're in the WiFi screen hit the menu button and under advanced settings there is the option to keep WiFi on during sleep. Also, as you have found out, be careful with any apps that directly control the hardware.

Had a very similar scenario as the OP described. Went to bed with it plugged in and streaming DI FM in high quality, woke up in the middle of the night by burning myself on the metal back plate. Unplugged it and pulled the battery, when I woke up in the morning after a rather worrisome night sleep I discovered my WIFI would not work unless I was within a foot of the router otherwise it wouldn't get any signal. I assumed the devices internals were damaged and that is what caused the problem, glad to know someone else aside from me has had a similar issue. Best bet would be trying to get a replacement through the warranty unless you have some type of protection plan through your carrier.

I see, thanks guys for the inputs. I had a feeling it's a goner. I can't do the warranty since it's rogers and I'm from the U.S.; bought it off Newegg unlocked without a warranty. So I guess I'm screwed.

Had the same thing happened to me. Had to send it to sammy to get fixed the had to replace the whole board

I've contacted mylaptopisbroke and they told me that phone repairs have been discontinued until midwinter 2013.
Is there anywhere I could buy a new soc??

Try mobiletechvideos.com or phonedoctors.com

I've heard of reflowing oneself by putting it in the oven at 550 degrees for 10 minutes or something. FWIW.
Not sure I'd want to do it myself, not having better information, but perhaps there's something out there some googling will reveal.

I've look at the sites, no captivate glide stuff. Guess captivate glide is not that popular a model. I've read about reflowing, but too chicken to try. I did took took the phone apart but saw that the LED is on the board itself and couldn't be detached; it's housed in some soft rubber feely box. I had a feeling it would melt in the oven.

in the options you can change it to keep wifi on all the time.. i keep mine on all day.

Yeah... I know that now... too late though.. ahah

What have you done with this?
Have you turned it on recently and found it still works?
I have a similar problem and other threads have suggested it's a software problem that might be fixed by installing a new ROM via odin

Screen Flickering Problem at bottom right corner only in Nexus 7 2nd Gen

I have searched the entire forum for the similar problem i am facing but couldn't find any and had to write to you in private.
I have bought my device 3-4 months ago from Bangladesh and cant claim any warranty or replacement. My device screen is flickering more often day by day at the bottom right corner. Its like a screen shot of the top or any other portion of the tab that is flickering at the bottom right corner. I tried the brightness issue, didn't work. Then I factory reset my device thought might be a bug but still no luck. Now i am worried whether this is a hardware problem or not. But i never dropped the device. So shouldn't be one.
I recorded the problem with my mobile to be more precise. Video attached herewith in zip file.
I would be really grateful if anyone can help me out with a solution.
Thanks.

It seems like your CPU/GPU is burning out... I had the same problem when over clocking my old Galaxy Ace..
The problem may not be the same, but its all I can think of.
EDIT: it could possibly be because the ribbon cable that connects the Screen to the MoBo is loose?

Ribbon cable...i thought of that too...hope that is the prob..it shouldn't be a great problem then. What if CPU/GPU is burning out...what will be the solution then? Thanks for your reply though.:good:

If the ribbon cable is loose, power off you device and pull the back cover off and have a look.
If the CPU/GPU is burning out, the only thing I would suggest would be a moderate under clock of both units and pray that your device will last, alternatively, throw your device at a wall to preemptively break it before they do die and your device becomes a really crappy decorative ornament.
Seeing as you cannot get a replacement, your only option is to try and keep it from happening by any means.. It is only a matter of time.
OR,
I'm wrong.

Last night i showed my device to a professional and as this device is not much available in Bangladesh, they are not expert enough. Though he suspected it might be the cable issue but he cant be sure. He might get it right if he gets another same device to test. So m left with very few options :crying:. I got to wait for the parts to be available or i got to contact the Asus product importers but fingers crossed. Disappointing...its just a couple of months and lot of money for me.
Anyway...thanks for all the help and support. Appreciate it.

am experiencing the same issue, plz notify me if any updates, thx

I face the same issue on my nexus 7(2013). Is there any solution to this?
Sent from my Xperia Sola using Tapatalk

I have this issue as well. Got a 16GB 2013 model free that had a shattered digitizer. Replaced the screen and for about 24 hours it seemed fine (only a little use). As I began to check it out and use it I started getting this odd flicking glitch on the bottom right of the screen, right edge to about 3/4 or 4/5 to the left. over time the amount of time the glitching occurs has gotten longer, and after re-seating all of the cables (they're in good and straight) it's pretty much constant now.

same here. i haven't even overclocked my tablet i might have to open my device up some time...

D855 OEM screen replaced but touch not working

Hello all
I dropped my G3 a few months ago and cracked the screen. Recently got it replaced with a brand new OEM screen.
When I boot the phone, the touch works properly, can navigate the menus, everything. As soon as I turn the screen off, only knock on works but the touch doesn't work. I can't unlock the phone unless I remove the battery and boot again. There's no touch available in TWRP as well.
I'm currently flashing a stock ROM, Android L, hoping that it will solve the problem. If it doesn't, I fear I may have to resort to other methods. If any of you have experienced this, please let me know as to what steps you've taken to remedy it.
Thank you in advance.

Did you do it yourself or did you send it in or take it to a repair shop? If you didn't do it yourself, I would take it back and demand they fix it at no extra cost.
If you did it yourself, did you get the screen with the digitizer along with it? Just replacing the screen, on most phones, without getting a digitizer already fused to it means trouble.
Also, if you did it yourself, check all connections. I know with my daughters iPod, I had to replace the screen and it wasn't easy and the first time, all the touch areas didn't work correctly. You also have to be careful that you don't ruin the digitizer when installing the screen.
Also, you have to be real careful of all the connectors and the board. One wrong move and you could tear a cable, crack the main board, etc. I refuse to do any more self maintenance on devices like this. Best to either shell out the cash to have it fixed, or just get a new one. That, or also get extended warranties to cover damage to the device.
Also, did you have it in a case protector? If not, you might want to go get one. Otterbox's are worth the money. Yes, it makes the phone bulkier, but I'd rather pay $40 or so for their protector which really helps.

A friend who's an LG technician did it for me. Replaced the screen and digitizer I believe. He tested it on another G3 and the screen works perfectly. Given that the screen works on another G3, do you think it is likely that this is a software issue and not hardware?
I have a case that came with the phone but I've never used it, however, that's definitely going to change from now on.

I can't even pretend to know what might be the issue. I would take it back to your friend and ask him to look at it, if not replace it again.

Yeah, he asked me to return it to stock and then test it seeing as his internet speed sucks, and if it still sin't working then he'll take it back to work on it.
Will report back if the software update works or not.

Just an update, flashing to stock didn't work. Only way I can use the phone now is to set the screen to never turn off

I've tried everything, finally figured out that it only works with the quick circle case. If I close the case and wait for the circle to show up then open it, touch works. It's probably something internal that's messed up but I've since given the phone to LG themselves for a quote and possible repair.

Help!!

Hey.. I flashed cm12 unofficial ROM 2-3 months ago on my lg d855.. There weren't any major bugs.. But recently I noticed that sometimes when I press the power button to unlock it .. The touch screen seems to stop working.. This happens only on the lock screen... I Also tried holding the power button and try to tap the "power off / reboot" buttons.. It doesn't work too.. But.. The weird part is..when I sort of slap the screen it starts to work again .. My question is .. Is it a ROM bug? Or is it a hardware issue.. If its a software issue.. Then why does it start working when I slap it.. And if its a hardware issue.. Why does it only occur on the lock screen? Please help.. Thanks

I haven't had this problem on the D851, but I would try updating your device to the newest version of Cyanogenmod.
Also, back when I had the G2 I went through this problem a lot and actually had about five of them because they were under warranty. The problem was that the seal for the screen would come undone, and it's hard to notice since the screen is literally the entire front of the phone. When this seal broke, water would seep in and cause chaos with the screen. Wouldn't work in certain parts and so much more. I haven't had this happen on the G3, but my seal has broken and I can see it, so it's only a matter of time before water gets in there (or until I get the screen replaced). I've always had this problem with LGs they're just so damn good that I live with it. I'd bet this is what's going on if it's not the hardware.

Absolutely... I can see... Whenever I press on the edges on any of the sides.. It sort of gets pushed in.. It looks like its not glued properly.. Its a bummer as the "screen" is the reason y I bought this.. From ur experience , does it stop working completely at some point?

If you can push it in then the seal is definitely broken.
On my G2, when in a moist and humid environment condensation would form on the inside of the device, but it was nothing too big and went away after a while. However, when too much fluid built up in the inside it began typing on its own. Furthermore, it got to the point where certain parts of the screen were unresponsive. This is why I had about five of them because over time it did get bad.
Although if there is water in the device rice usually absorbs it. Get a ziplock bag and fill it with rice. Take your battery, sim card, and sd card out, then place the phone in the bag full of rice. Seal it and shake it up a bit and let it sit over night. Keep the back cover off as well. If this is an option. I understand you might need your phone, but if you get a time where about eight hours are free I would highly recommend this. I have no idea how it works, but it takes the moisture out of the phone. I've done this with waterlogged phones, my G2, etc.
When I did that on the G2 it fixed my problems until moisture got back in there. I don't take care of my phones too well, so moisture got back in fast. Try this out and if it works just avoid keeping your phone in moist places (like playing music in shower, being on it while raining, etc.). If this fixes the problem it should hold you off until you can get the screen resealed or a new screen.
If it is with the hardware and its still under warranty I would get a replacement. I would revert to the stock ROM (if you made a backup) or find one and make sure it's updated. I would then do a full unroot, and attempt to make it so they cannot tell it was rooted. I would then attempt to get the replacement. Rooting voids the warranty, but if you unrooted I doubt they could tell. Furthermore, if you have insurance on the phone this could also work.
Edit: If you try the rice then try to replace the screen I would ensure that the current screen works properly after the rice. Make sure all the moisture is out before you replace the screen that way no moisture is trapped in there.

First of all.. Thank you soo much.. Thank you for the time.u put into these posts.. It has really helped me.out a lot.. I can totally see how the rice method could work.. But it has not got to the point where its un-usable.. As I said, its only in the lock screen.. It has never ever occurred during actually using it.. I haven't found any dead spots.. Nothing.. If I use the rice trick to take out the moisture,, and if I can use the same screen (which should still work) can I just take it out and glue it in to place? What type of adhesive should be good... I'm asking this because I got this from abroad.. And it's not an international warranty. So there's no way I'm getting a warranty replacement .. So ive gotta make with what I have.. But this is very sad though, specially from such a big company.. I mean gluing a screen is not that hard.. I played loads.. Lol.. I really hope hot glue works lol..

Well then I'd try to fix it before it does get unstable! Thing with the lock screen is you're swiping and the moisture defuses the area you're touching which could cause problems. Definitely try the rice! However, I wouldn't recommend gluing it yourself. I imagine it requires some sort of water and heat resistant glue to be effective, and on top of that a professional application. Hot glue definitely won't work! I imagine you want something that looks nice and I can only seeing that being messy and leaving residue. Furthermore, I'm not entirely sure on what lies beneath the screen and if disturbing that could cause further problems. However, I understand you're probably planning on it so please watch a guide such as: https://www.youtube.com/watch?v=PcoEQVtUwYQ to see how it's done and what you need. There seems to be a lot more to it than just placing some glue on the screen and pressing it back down.
I'm sure you can get a replacement kit with instructions and all the required tools to do it properly for not too steep of a price. Check this out: http://www.ebay.com/itm/Replacement...46?pt=LH_DefaultDomain_15&hash=item54198f441a
Or you could take it to a professional like those at Broke Ass Phone: http://www.brokeassphone.com/smartphone-repair-selection/lg-smartphone-repair/lg-g3/ The price is steep, but it's professionally done and comes with a warranty.
Good luck to you!

I haven't had this problem on the D851, but I would try updating your device to the newest version of Cyanogenmod.
Also, back when I had the G2 I went through this problem a lot and actually had about five of them because they were under warranty. The problem was that the seal for the screen would come undone, and it's hard to notice since the screen is literally the entire front of the phone. When this seal broke, water would seep in and cause chaos with the screen. Wouldn't work in certain parts and so much more. I haven't had this happen on the G3, but my seal has broken and I can see it, so it's only a matter of time before water gets in there (or until I get the screen replaced). I've always had this problem with LGs they're just so damn good that I live with it. I'd bet this is what's going on if it's not the hardware.

Hi, ItsJacobee,
Sorry for breaking in, I have the same issue with 2000ftt, and I did tried "rice trick" but no luck. I think the screen is perfectly fitted in the case, when I press the edges, the feel is solid and no room for further pressing in.
My device is D855, I flashed many custom roms (resurrectionremix, CM12, Nameless ROM, CloudyG3 2.1), the mentioned issue happens to many of them but never happened in CloudyG3 & stock rom.
Any idea?
Best regards.

Is it under warranty or do you have insurance on the phone?

Yes, it is under warranty, I am going to restore stock ROM and take it to service center. But I don't know how to trigger the issue (touch screen no response at lock screen while using power button to wake up), in stock rom and cloudyG3, this problem never happen.
Best regards,

Restore Stock ROM AND do a full unroot beforehand.

Thanks for reminding. I restored the phone to stock with the downloaded .TOT file, then go to service center.
I can't trigger the problem in front of the service guy, however, they ask me to left the phone for checking, one day later, they confirmed that my phone is working fine no need to do anything, nothing to be replaced.
CM12 is already good enough, its speed and battery friendly....
I wish developers of CM12 would somehow fix the problem in future updates, as I knew some D855 user (but not much) also having the same issue.
Best regards,
