[Q] Screen flickering/blue pixels?! - Galaxy S II Q&A, Help & Troubleshooting

The problem with my S2 is that when the phone gets cold the screen starts flickering then the screen it's all "blueish" and the text becomes unreadable like the resolution is very low. It started doing this thing rarely and now it appears frequently. I am not able to post the video link here because I am a new user.Please search "Galaxy S2 Screen problem". I will post a picture also (sorry for the bad quality).

These are the picutres, first one at full brightness and the second at the lowest brightness.

Hardware issue.
If the phone is under warrenty, return it and insist to get a new one. If possible, reproduce this issue at the store/service center.
If the warrenty is over, use nuke scripts (both ROM and kernel scripts), reflash the device to perfectly stock condition and see if there's an improvement. I, personally, doubt it but it's worth a shot. If still the problem persists, take it to repair.

It's the same as I og into recolvery, so the ROM/kernel is not the problem, I don't heve waranty because I had dropped the phone and smashed the screen 6 months ago, do you think that the GPU can cause this problem?

So....you replaced the screen...?

Yes, I did replaced the screen with a genuine one at a service. The problem started 3 weeks ago.

[Q] Display screen full of "snow" for NO apparant reason!

Out of the blue, for NO apparant reason, my display screen is suddenly full of "snow". The phone itself is working properly because I have the HDMI out cable and I can see everything working properly when I use my TV as an external display. While using the HDMI/external display, the touch-responsiveness is normal.
I did do one hard/factory reset, that did't fix anything. I get a similar screen when the phone is in the OFF position and charging (when you should normally just see the picture of a green charging battery icon.
I know this looks like the symptom of an impact or some other physical damage, but I take SUPER good care of all of my devices and there is no way that I caused any damage to it. Earlier today, I was using the phone and all was well then I put the phone in my pocket. About 3 mintues later, I pull it out of my pocket and this is what I see!
Has anyone seen anything like this? I bought this phone about 6 months ago from expansys-usa, so I assume it's under warranty, but if there's ANYTHING I can do here myself, I'd rather take care of it here.
I'm a fairly advanced ROM flasher and am pretty comfortable taking phones apart and getting them back together, but I don't want to open this one up if it will void my warranty with expansys/Samsung.
I welcome help/advice/thoughts.

Best thing for you to do if you've got warranty is flash a stock from specific to your product code like you got it. delete everything on your SD card related to Modding and get a replacement for your warranty. Looks like hardware problems

Problem with Xperia U ST25i Screen

I have a problem with SXU screen. First I have some kind of "bleeding screen" on the left edge of screen. In my country (Serbia) in Sony service center (ComTrade) told me that is a normal and that my complaint not justified. I also have one green stuck pixel in lower right angle of screen. I noticed it 6 days after purchase. But Sony service center and retailer didn't want to acknowledge the complaint. They told me that one or two defective pixels is acceptable. What's worse this is the third Xperia U phone that I have a problem with him. The first one I returned because of 4-5 defective pixels. The second one I returned because it was totally dead. And now one stuck pixel. It amazes me the Sony quality control check and after-sales service, at least in my country. I know that first problem I can't solve but what about stuck pixel. Any solution? Phone is old 3 weeks. Please help!!!
Some kind of "bleeding screen", is it normal?

I've got the same "bleeding screen" issue, but i really don't mind it, i think it's normal.
And I think that stuck pixels are kinda normal thing, you can try "waking" them up by some LCD checking apps, which display RGB colors on your screen fastly - i had frozen pixel issue on my psp and it worked. To sum up - sony don't have to take that under warranty.

"bleeding screen" is not an issue, that's the way LCD's are glued...that's ok.
I have one dead pixel and Sony say the warranty covers only up to 4 dead pixels...well, screw them
Akso my screen is bleeding

[Q] Screen Broken - Advice

Good Day All,
I am in a bit of a predicament. On Saturday, I had my phone in hand and heard a *crack* (I can only suppose my subconscious telekinetic powers were left on), looked down and noticed that there was a somewhat small crack about 1.5 inches up from the back capacitive button all the way across to the home cap button. Basically making any key presses in that lower region of my screen and cap buttons unusable.
I just watched the YouTube tear down video and I'm curious as to if I purchase the Touch Digitizer Screen Assembly(See pics below) will this cover everything that I need for the replacement?

I found a US supplier on eBay with it for $170.99 with a decent ship time (4 business days).
--I have noticed that Most of the non-ebay suppliers are out of stock on the digitizer all together.
Any suggestions/advice is much appreciated.
can't u just take it to a fixer it's the safest way if ur nervous

Click to expand...
Click to collapse
Because the local "fixers" are gonna want to charge a markup on the actual screen/assembly while still adding on for repairing the damage. Versus actually buying the part myself and giving it to them to fix(Which is also a probably option).
Have you contacted LG. I heard they do the repairs too. It's obviously much safer and I think cheaper.

Camera focus not working at all (stuck)

My phone's focus won't work at all, even when I tap an object in the background. The focus is permanently set for objects 2-3 feet away.
I'm using stock ROM (5.9.020S) on an X820. Previously the focus worked but it seemed to make a lot of noise, and it would sometimes randomly cycle through different focuses even when nothing changed (I'm assuming this is the autofocus bug that other people have had).
Anything I can try? I've wiped the phone and the same bug persists with factory settings. I get the same issue in multiple camera apps (including the stock app). I had a lens protector covering the camera, but removing that didn't make a difference.
I saw this thread with possibly the same issue, and I notice that when I shake the phone, the focus seems to come unstuck and work partially. But it's a nightmare getting a sharp focus long enough to take a picture. Anything else I can try (besides the freezer trick or sending it back)?
Have you tried going in the settings and toggle the tap to focus? Try that, hope this helps

Did you tried replacing the camera module?? I'm thinking to replace it with the one available on AliExpress.
*The Leeco should support this phone for atleast an year but seems like they will not. Helpline no. Dead, Service center closed or they make excuses. They just ate our precious money*

General Oppo Find N screen already broken

Very unfortunate, the main screen of my brand new Oppo Find N is already broken. I haven't dropped it or covered it with dust or sand, just had it in my pocket for 5 days. When I opened it today there was this white line. With the finger i felt a piece of dust beneath the screen - the hinge seems not very safe against dust from the pocket. It reminds me of the first Galaxy Fold which was very sensitive. Very unfortunate. I hope no one else has a similiar issue, I'll send it back for warranty coverage...

Wooooow
Thats a bit concerning…
That is very concerning for sure. I spent a lot of money for the phone and question the type of warranty I will get from the seller I purchased from. I had not even thought about this outcome before and has me very concerned for sure.
Wooh this is not good... Hope you can get some help with the seller or through de warranty....
Cheers
Did you resolve the issue via seller or source a repair (presumably screen replacement?) - I'm looking at a phone with a similar issue - did it need to go back to china to be repaired & did that happen okay?
I'd be interested in your outcome
OP no longer posts in XDA forums hence no matter whether his phone was repaired or not, it seems he moved to iOS.
Device was replaced.
where did you get your device replaced? I have the exact same thing happened to my phone!
Same question. I have a black dot (diameter 0,4 cm ) on the unfolded screen
