[Q] Odd camera problem

I can't find this anywhere so far, so I thought I'd ask you guys.
I recently updated the ROM to thr newer Tmobile one on HTCs website. First the camera stopped working, hard reset solved that one. Now it's doing something else.
If I take a landscape shot I get a small set of interference lines across the top of the image, if I take a portrait shot the interference lines become a large wedge down one side of the image. These lines are not there when the phone shows a preview image, but when I look at the saved image the interference is there. Presumably that makes it a software issue.
Is there a way to reinstall the camera?
I attached a portrait image to show the effect.
Cheers for any help,
Tony.

reflash/update the rom again. then when started up, reset by switching off your mobile. Once started up, now try the camera. If you stiil have the same problem, then flash back to the original rom, before the update. See if its ok on that one.

who can said how i can remove this words. i already changed firmware and the problem is still present =(
It is called screen burn in. you can only fix it with a new LCD software won't help.
Edit: Actually I remember hearing about a white screen fix, where you keep it on a white image for an extended period of time. I'm not sure how long you need to do it for or if it even works.
thank you.
i will try it.. i also bought app from market for 3$ to fix stuck pixels but it wont help =(

[Q] Screen/Software Issue S3 - Need People To Test PLEASE!

Hi Everyone,
So I have noticed with my new S3 that when I do certain things my screen colours are change. For instance if I am watching a movie using there new picture on the home screen thing and then I set it back to full screen and rotate the screen and then put it back on the home screen the text in my text messages is all screwed up and has a white border around all the text. As soon as I close the video this issue resolves it self.
Would this be a hardware or software issue and can any of you please try this for your self.
Thanks in advance.
EDIT: Can some of you S3 owners please do the following.
1: Load up a video with the default player.
2: Use the picture and picture feature.
3: Then return the video to full screen by tapping on the small video.
4: Then rotate the screen with the video playing to full screen.
5: Then return the video to the PnP mode and load up your text messages.
You should see your text has a white haze around all of the text.
Can someone please confirm.

Your phone comes with an LCD test menu. You could use that to check for any issues on that front.
Following instructions from The SGS3 Indian FAQ and Discussion Thread could help you out. Thanks to Bala_gamer
* Enter the dialer and input the following code "*#0*#, it will give you a set of options to test the mobile.
* The same lcd test menu can be used for testing the tint issues, the main menu of the lcd test should look white rather than pinkish white or warmer white. you can either decide it yourself by your eyes or compare it with another AMOLED screen.
* Black dots are present on almost all AMOLED panels with varying intensity. Its not an issue. But if you still want to check for lesser dots take your mobile to pitch dark environment and load a complete black wallpaper, once your eyes get setlled to the environment look over the scrren. you will notice those spots.
I hope this tells you where the problem is. Lemme know if it works.
Hi,
Thanks for the information I tried it and everything looks good. I went down to my local Optus dealer today and I could replicate the same issues with the pebble blue handset they had on display. It seems to me it's a software issue.
EDIT: Can some of you S3 owners please do the following.

Well, what do you know. You were right!..Never would've even thought of that, come to tell you the truth. I'm afraid I'm completely out of my depth here. I've faced the same issue. Try posting the question in the forum I posted in my previous reply. The admin should be able to figure it out. I'll second your post.

I have same problem. But no solution.

Screen overlay on Samsung Galaxy Note 8.

For the last two days I noticed that I have another screen under my main screen. I dont know how to explain, but its almost like my main screen is see through and I see another layer under it. Everytime I browse or open anything with white screen you can clearly see another layer. Its appears to be large bar on the left side of the screen and 3 buttons on the bottom of the screen (mic, record and idk the third one) I dont know how to post screenshots here, I took couple and would like to post them along with my post, but Im newbie here and cant seem to find attach button anywhere
My phone is Unlocked Galaxy note 8 SM-N950U1
Solution. Update! Found problem
It turns out its my google navigation burned into the screen. I downloaded Burn Test app and looked at icons closer and realized its from Google Maps wilhich I use all day as I am a truck driver. Image of the map just burnt in. Looks like there is no fix for that other than replacing device
