[Q] S2 Flickering display, back cover stuck - Galaxy S II Q&A, Help & Troubleshooting

Hi I am mostly satisfied with my G2 so far, but have two concerns:
- The display is flickering. It is especially noticeable in applications with large white areas, such as Remember The Milk.
- The back cover sits on really hard. I broke my nail in two places when trying to open it, and my attempt with a screwdriver had to stop because it seemed to be able to crack the cover...
Is my unit a faulty one, or is this usual?

Are you using the slot in the back cover to open it .

I had the same issue with the flickering screen, was so annoying especially on low brightness. I had a thread about it as well.
I thought maybe I can live with it but I couldn't so went to o2 and replaced it.
Go and exchange it!

Thanks for your input. Was your device faulty, and did the new one work better?

Well yea o2 swapped it for a new one and this one doesn't flicker at all so the previous one must have had a defect some sort of.

Dust Under Screen?!

I dont know why it is with these newer model phones, but just from the suggestion posts that came up when i entered the title of this thread, but My LGOT and i guess even the G2 have an issue where dusts starts to build up under the sceen....
Ive only had my phone for a little over 2 weeks, but even after the first couple days, i noticed that there were already a few trickles of dirt right around the middle of my screen.
I guess my main question is, is there anything i can do about this, has anyone had the same troubles, and what can we do to prevent this from happening?
In Thailand this is general problem of LG Optimus One
you should contact LG Customer support
they'll open your phone and blow dust out
if dust cause touchscreen malfunction they'll change new one for you
some people guess that dust already in the phone due to assembly process from factory
some guess maybe dust go through usb port
I have my phone since 2 days and i already have a dust spot in the lower right corner. This is annoying! If this spot is growing i will contact the costumer support.

I am working on dusty area, but no dust under screen. Phone is 1 month old.
Me I have not this problem, but remains me the same issue with the iPhone 2/3 (google iphone dust screen).
I think it's a common problem with capacitive screen, but no "easy" solutions to fix it...
poor construction quality, imho.

this is one of those instances where a really cheap phone shows its faults. the phone is free on contract and little of $200 without. with it being so incredibly cheap, there is going to be something wrong that causes concern.
Im okay with it happening as long as it gets fixed and the problem is acknowledged by both LG and the phone carriers. it seems like many people are having this problem at the moment and T-Mobile is willing to exchange it in store, so good on them for being considerate.
i have the same issue. Don't know how to prevent that

No dust here either. I have a silicon case, I don't think it helps very much.
just disassemble it. There is no warranty seal. You'll find the dust inbetween the lcd screen and the capacitive overlay.

Hi! please tell us how to do it!
I too have this problem Can any one please let us know how to get rid of it.
I have the same problem with my Optimus One, dust is starting to gather on the right bottom corner and it seems to have increased since the first time I saw it. I've thought about buying a can of compressed air and trying to blow it near the edge of the screen but maybe that will just make it spread even further.
I've also thought about unscrewing the screws on the back panel of the phone and clean it but I'm afraid that it will affect the capacitive screen in some way making it less responsive and that after I assemble it back together it'll become even less air tight and thus accumulate even more dust.
Maybe I'll reclaim my warranty but I'll have to un-root my phone and wipe it clean before leaving it at the store and it's going to be a pain in the ass to reinstall everything when it returns.
Will they replace the mobile for this problem?
You can back up everything by titanium backup and copy the titanium backup folder from sd to your pc or pen drive. In your newly replaced phone you can copy back this folder to sd card and after installing titanium backup application you can restore everything.

[Q] Strange screen problem

Hello everyone!
I'm new here, and don't normally post on forums about technical issues (too nervous!) but something very odd came up on my Galaxy s2 today and my google-fu has failed me so far in finding anything similar.
I got it at the beginning of September this year, keep it in one of those leather wallet cases to protect it (and a screen protector), and during the day it mainly just sits on my desk at work. For some reason however, today, this just appeared (see attachments).
It's a small, lilac-purple smudge in the lower right hand corner. It doesn't move when the screen moves, and the touchscreen still works just fine. You can also still see images below it, it just tints them purple. It's less visible when the screen is brighter, but still kind of there.
I have turned it off an on again, turned it off and removed the battery, and left it off for a while to cool down. It was still there when I turned the phone back on.
As far as I know there is no water damage, and I don't believe it has been in contact with any magnets (apart from the mini one that clasps the case shut). I'm completely baffled! Is it a defect, or something I've somehow managed to cause? I've tried to be very careful, as I know what a klutz I am! The phone is also not rooted or hacked in any way.
If anyone has any thoughts or advice, I would greatly appreciate it!
Thank you very much
I think is magnet

I wondered the same thing, but I left it on a table next to my bed overnight and it seems to have gotten worse - the purple has spread further on to the screen.

to which is why never used a case with magnet.
OP:
It will get progressively worse even if magnet is no where near now.
The purple tint on the entire screen is definitely a defect... get it changed from the Samsung Service Centre! Even I had this problem and my phone atm is at the Service Centre...
There are lot of quality control issues with the SGS2 display...
Never a Samsung again!

The back snaps

My wife got the DNA yesterday and she is very excited about the new phone (coming from four years on the iPhone). However, the phone makes a fairly loud snapping sound if you press and then release the back cover. It does the same when you squeeze from side to side. Not too hard, it happens even with a normal amount of pressure necessarily if to pick it up. It appears the back cover may not be attached or glued property.
Do you think I should replace it?

Nexus 10 back loose/ creaky?

Hi guys,
My Nexus 10's back, on the left side when facing the screen, has a slight creak to it when pressed. Does anybody else's have this (it can be slightly hard to find at first)? I'm curious, as I'm not sure if there is a DIY way to fix it, and whether or not it is a common occurrence.
I get a click or two from the removable strip but I assume that is just it moving in its seating. Very minor and not a problem. I ignore it.
Yeah, I have that, too. Nothing seems to indicate that the cover is loose somehow, though. Seems to me that it's just the rubber. I wouldn't worry about it. Of course, I wouldn't go choking it there, either.
Sent from my Nexus 10 using XDA Premium HD app
I too get a "Crack Sound" or creak when I grab my tablet from the left side.
Mine is same although my removable strip actually has a probg yhat won't go it so it juts out... Very annoying but I have a case.
So, besides the creaking sound (which doesn't bother me too much), my back actually has two "bubbles" where the back material meets the dimpled strip, and when you look at the tablet top-down, you can actually see the two gaps where the rubbery material is lifted up higher than the dimpled strip. The "bubbles" are basically directly above the "N" and "S"...
I'm assuming this isn't normal and should probably go get an exchange at the store, right?

My left rear has a little more give than the right. Otherwise, the build is clean and sturdy. Did hear a noise once when i was gripping it at a funny angle. Of course if I grip my Vivid wrong the rear plate falls off and the battery even drops out at times. Overall I am very happy with the construction of my nexus10.
like this?

I got my N10 yesterday and I found two problems.
1. The back is really loos. If I press in the middle of the back cover it wobbles and make click sound.
2. There is some light bleeding at the bottom right corner of the screen.
Are these things normal? Or should I exchange it.

The back is fine. As far as light bleed, it's a common problem. How bad it is depends on how much it bothers you.

i get some slight play in the back but compared to the note 10.1, this thing is build like a rock
I received my Nexus 10 at the end of January and have just ordered a replacement...
The creaking and cracking from both sides of the back (directly behind the speakers) is horrendous when I gently squeeze the nexus, for example to lift it - I can usually just ignore these little things, but this is just too bad!
I have a Galaxy Nexus and I love it...the build quality is superb and the fact the Nexus 10 isn't up to the same standard is disappointing.
I will upload a YouTube video to demonstrate it...as I've not seen or heard anyone having creaking this bad...
When I receive my replacement, I'll update this topic. The only saving grace was the Google RMA process was flawless IMO.
CASES
I used to get it too but i figured out a way to fix it. Wanna know how? lol Get a nice smart case by Poetic or another brand you prefer. I know theres a thread designated for all the accessories for nexus 10.

Check your Lumia 920 for unibody defect

Hi all, I found a defect on my Lumia 920's unibody casing. the top bezel is somewhat loose and it squeaks when the phone is cold and clicks when the phone is warm. I find it very annoying because I like to grab the phone from the top and bottom. here's a video of what I'm talking about:
http://www.youtube.com/watch?v=Vevk0LIlLPo
I already replaced my phone at my Rogers store... you might want to check yours and replace if necessary. I feel the clicking will get ALOT worse in the summer when the weather is hot.

funny you mentioned this, i only just noticed the exact same thing about a week ago....
I had a similar issue with the unibody also.
It make noises when I press between the power and camera button.
I took the phone back to the Nokia Care and after more than a week I went there to have him back but it had the same issue. So I give it back one more time and I'm still waiting....

do you guys all have the black version? I've heard that apparently different colored unibodies also have different stiffness...
also when did you guys buy your phones? build week?
I'm planning on getting a yellow unibody to switch out my black one.. but first I have to guarantee the yellow shell won't make those noises...
thanks for the replies!
I have a very slight click near the top of the phone (but not constantly) and that's it. I have the white version. I won't bother changing it because until I read this thread I can't say I even noticed it.
I got a black one on launch and its quiet. No creaks, squeaks or clicks.

I have this effect at right side at the middle and at the top. Won't bother with replacements until it will be getting worse/other defects will appear.
To me it is a minor thing. Also no warranty that new one won't start to click after time.
If you put it in a protector like one should with a 600 dollar phone you won't ever even notice this issue. Plus other than an annoyance it has no affect on the phones function.
mine too
I have a black hong kong version. There's a creak/squeak at the middle left (no button) side. which is little disappointing to me when it's the most expensive phone I bought and build quality was very well reviewed.
Mine does this if I press in the middle of the bottom half of the back. Strange thing is it doesn't always do it, seems a fairly random issue.

Hello,
I have the yellow version from November last year and I didn't encountered any problem with my phone; I saw a lot of users that have problems and some strange of them but I haven't.

I have a red Lumia 920 and I am on my 4th unit because each previous phone has had creaking issues on the body. Now, these haven't been the only issues I have suffered but the others are irrelevant to this thread. It does annoy me. I cringe whenever I picked up the previous phones because of the creaking it would make. It makes the phone feel cheap, and quite frankly it shouldn't and thankfully Nokia agree.
I have had my current phone for a day now and so far no problems have developed so I am hoping for the best.
mine was fine until I dropped it twice in the same day (within about 10 minutes of each other) once on concrete, then for some reason decided to drop it again and it bounced off 3 different objects, since then you can hear a 'click' if I press down on the top of the phone in the centre near the front.
bit miffed as I have a scuffed corner now on an otherwise mint phone, have had it for a good few months tho so the novelty of how shiny and nice it looks has almost worn off
I have the white one, a friend of mine has the black one and has no issues with creaking/clicking on the case, but then he has had a silicon case for it since the day he had it, maybe that's helped?
Well, I have had the phone for 5 days and the squeaking/clicking appeared yesterday. I realized that a part of the body feels "hollow" inside so I proceed to disassembly the unit.
When I take out the cover noticed that in fact there was empty space between the case and the board. I put in some supplement (I had to try with several ones until I found the piece that let me close the phone with no extra effort or excessive pressure). Once I get it right, put the parts toghether again and the squeaking/clicking was gone. Also it doesn't feel hollow like before.
I think is a problem with the material expanding and contracting under different temperatures and because it doesn't have a true anchor to the sides (it goes in and out very easy, no extra seals on the sides). Pretty nasty thing for a High-End device.
PS: My carrier (where I bought the phone) said that it was "normal" and refused to replace the unit. Normal my ass!
Aside from that I'm very much inlove with the 920 and WP8.

I hope your supplement is a material that does not generate static electricity. Otherwise your fix may damage the phone beyond repair. Things like paper, cardboard, plastics like bag material that is not treated, cloth, and many others all generate static when in contact with other non conductors like the inside of the phone body. Just a warning from an RMA tech who has seen ESD damage from bad fixes and the customer stuck with a voided warranty.

Yeah, it was non-conductive material. I sort of a tech guy so I know a little about that. I used something that I commonly use as aislant and vibration cancelling in my PC mods. But thanks very much for the warning anyway. :good:
Following the case, after keep ranting about that flaw with my carrier (and phone vendor) I'm with my second unit now, also yellow. I noticed that the power/lock button is lower that the volume and camera buttons but its not a problem (it is lower compared with the firt unit, if this one was my first surely I was going to think that this was the original design).
I've been looking like a paranoid squizo for other defects but so far, so good.
Pretty lame for a high-end phone and a WP8 flagship. Even if its just a batch. Still,, I freaking love the OS.
