[Q] Can you fix a stuck pixel on AMOLED screen?

Just noticed on my phone earlier when i unlocked it that i hat a red dot near the bottom. Ran a pixel test i found on the market and it shows up on any background and my brightness setting doesn't affect it. Is there any way i can fix this?

Press hard on the screen where the stuck pixel is so the screen distorts in that area and hold for 10 or so seconds. Thats how ive done it for my lcd monitors and its worked.

That wouldn't work anyways cause the screen it under a hard glass cover. Also its not a true lcd screen its an oled screen

Maybe an app could be developed that uses the device gpu/cpu to mimic the effects of Pixel Tuneup?
I can't link because i'm new, but it's pixeltuneup[dot]com.
Just a thought. If this turns out to be a widespread issue, a simple app might be something people would pay a buck or two for. From what I understand, PT just puts out a calibrated video signal that is good at fixing pixel issues.

Ill have to give that a look and maybe contact the developer. Its not that bad of a problem but i always find myself staring at it lol

So does anyone else have a possible idea? I've looked all over Google recently and can't find much about fixing oled screens.

I supposed you've tried the screen calibrators that flash a whole bunch of colors. Thats would really be my only advice. If it doesn't work out a warranty replacement would be my last resort

Yea I've tried a few if those already and left each one run for about an hour. As for a replacement i wouldn't be able to do since i just got this one after my last one broke. Also I've have this phone for a little over one month or so :/

So why can't you get a replacement ? The phone is to be free of defects for a year, even if you already replaced it. Stuck pixels are a manufacturing defect which is covered under the warranty. If you got it in store, go back to the store. If you got it from 611 or online call the 1800 number and tell them.

Ah ok i see what you mean now. My next issue would be to find a stock 2.3.6 Rom

S pen issue

So whenever I try and use the s pen it sucks. If I hover over anything it acts like i selected it. I just want to know is there a way to disable this. I don't want the s pen to do anything unless I actually touch the screen with it.

My phone also does this. I'm waiting to see how bad of a problem this is before I make my decision.

I believe that's the Airview feature of the S-Pen which you can disable from the S-Pen option settings.

It's a known problem.
Some people have taken the pen apart. Rather, i just slammed the pen on a hard surface a few times.
Fixed. I'm not joking. Try it. I promise you it will work

What, like throw it down flat, or stab the point onto a hard surface?

Had the same problem, returned the phone and got a new one.

maybe they should put that in the user manual!!
Glad it's working for you. Cant wait to get mine on the 29th

Holy ****, it fixed mine. I dropped it with a little bit of force, and sure enough it quit messing up. I appreciate it. I was also about to return mine.

I ended up swapping my pen for a returned pen. Tapping the pen mostly fixed it but it still had a problem on a the right side of the screen where I would have to tap really hard to activate a button press.

Best troubleshooting for your S Pen
Thanks this method worked for me too!!! Gave it two gentle slams on the table and was good to go. LMAO!! I called samsung to report the issue and they had no way of helping me out, I will call them back and have them implement this technique into their troubleshooting steps.

S Pen Issue
Having a problem, wondering if its just me.. When i go to use S Note, the pen is automatically set to the eraser, and if i select the brush mode, its still using the eraser. I can only write if i press and hold the button on the s pen, then bring it close to the screen.. and then its like an etch a sketch where my lines would all be connected.. As soon as I take the s pen away from the screen and go to write again, its back on the eraser! any help would be greatly appreciated..- Matt

That's not how it's supposed to work. Maybe you have a defective device? Either way I would bring it back to T-Mobile to get it checked out. Are you running a custom rom?
Sent from my SGH-T889 using xda premium

Mine was hover selecting too but updated to the latest OTA, still had the issue. So I disabled and re-abled Air View and my problems were fixed. All has been good for a few days.

Yeah, it was working before but now its just all screwy, im waiting for my buddy who also has the Note 2 for tmo to come by im going to try his pen. This way I can figure out if its the pen or the phone. Thank you for letting me know that this isnt how its supposed to work!

Installed it straight out of the box... turned it on minutes after installing it. I would give it at least an 8.

I've only had the device about a week... And no, it's not noticeably thick. You can tell it's there, but it's very smooth; I personally almost prefer using my screen with this rather than with just the bare glass.

I have the invisi-shield extreme and I like it... it's not really thick or anything and it's like a insurance in protecting your phone... the only thing I had a problem with is... there is this spot on the phone that arches over the home button and there is a small space between the button and the shield.... well it just so happened I was getting out the car heading in to work was getting all my stuff together and I dropped my keys which had a small lock on it for my backpack... and it hit perfectly on that spot and shattered my screen from that point and cracking lines went up the screen... I was irritated at first.... but got my replacement with my insurance policy and got my extreme shield transferred over to that one... but other than that little weak spot it's a really good protector and doesn't affect the screen touch at all... hope this helps your decision

Messed up screen

My wife let out 2 year old play with her phone. He threw it on the ground and now the screen looks like this. Any ideas?

Damaged digitizer. Not cheap to fix.

It may not be the Digitizer. This phone has had a lot of abuse hurled at it by various members of Toddler class. It has time and again proved to be solid.
Just to rule on hardware or software issue, can you comment on if there are any other issues except display ? Also did the 2 year old threw on hard concrete or carpet ?

Haven't noticed any problems but the screen and he threw it on tile floor

Well just about 25% of the status bar is black as well as part of the screen. I'm sure rebooting the device or doing a factory reset isn't going to fix it.
But hey let's see. Supamike88 boot into recovery and see if the issue with the display is present there. To get into recovery press and hold volume up, home button and the power button and release them when the phone vibrates and you see blue text in the upper left corner of the screen (which in this case you might not see because of the screen). Is the issue still present?
You could do a factory reset to see if it fixes the screen, just back up everything before doing so.

If the screen is black but the phone still works, then its most likely the digitizer like I pointed out earlier.
You can buy a new digitizer and replace it, but its not really recommended. You might as well get another S3.
You could also just sell it for parts and try to get another S3. (I wouldn't recommend this unless you can do a factory reset).

Good for you. Please note, when you get the new device back, carefully read the label behind the battery. You may get SGH-T999L instead of existing SGH-T999. The L stands for LTE. If that happens, you will be in luck. But need to understand its not the same device but rather newer version.

Permanent screen smudge

Hi, I was planning to sell my n2 to get the 3,it's in perfect condition with every accessory still in its packaging, however i think i won't get much on it since i have huge smudge on the top left of the screen. I dunno what caused it but I'm thinking it's due to playing tennis game on it a bit. Has anyone else experienced this?
Any solution?

Those are finger marks, you're right that it's caused by games. Notice there's 3 areas affected, where the directional pad is and where I'd assume there's buttons A and B in that game. And that's why I use a screen protector. If you don't then you can get the glass replaced, not recommended as it's not 100% safe.

It's probably the oleo phobic coating rubbed out in those areas. They do sell oleophobic replacement kits online. Try it out.

come now, it's a phone and not a suite of armour. anything subjected to daily rubbing in 1 certain spot will show wear and tear. Your logic is disappointing
