Green/purple bleed on edges - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hi everyone, I made the mistake and wiped the screen of my mi9t with alcohol. The screen works fine as before but now the curved edges of it are a little jagged and a bit green, one is a bit pink/purple. The olephobic layer is still one the screen, I checked.
The bleed is small.
What should I do? I'm scared that something will go wrong... Those colors weren't there before, and they are visible only when their part of the screen is white. Should I maybe put it in rice to soak the alcohol (if that's it)? Or is it harmless? Please help. Thanks in advance!

That could be light refraction from grease or alcohol residue. Try to gently clean it off with a microfiber cloth.

Screen Protector Bubbles & Dust: normal?!

Although I paid the outmost attention while I was installing it, my Boxwave Crystal got some dust and bubbles (especially in the edges). I noticed that these imperfections cannot be seen when the screen is on, but for the heck of it, I want to ask: is it normal or am I simply incompetent?! :?
After getting a fine scratch on my (then) new 3970 I put on a PPC Techs protector and had the same trouble as you.
When I replaced the 3970 with a 4700 earlier this year, I had the screen protector waiting before I unpacked the iPAQ... Same tiny fluff and bubbles.
Now, after putting them on the two 9100's we have, I still can't get them perfect
Guess that just means we're both hopeless

I don't think anyone can get them perfect.
put mine on today. thought it was perfect but still bloody dust under it. sigh.

It's a pain to do I must admit but I've managed to get mine almost "perfect" over about 99% of the screen. It's just around the extreme edges that I've got some bubbles and issues where I'd forced it to go down onto the screen but the rim of the case was just in the way.
If you find that you can't do it first time, then get some sticky tape and put that on the side that sticks to the screen. make sure the tape on one of the edges is right up to the end of the screen protector and the other end of the tape folded over so you've got something to pull the tape off of the screen with when applying.
The tape magically takes off the dust so that when you're applying it to the screenal you need to do is try to make sure no dust particles exist.
You could always try hiring out a chip fabrication unit where they're hermatically sealed too...
I've done a few Ultraclear versions and got it down to a fine art.
1. Be calm. Allow youself plenty of time. If you make a mistake, take a deep breath and start again. Don't rush or you'll end up ruining the film. Even though I've done this several times, I still allow myself half an hour.
2. Trim the narrow edge off an old credit card so it has a straight edge with sharp corners, and get some screenwipes or lint free cloth.
3. Do the fitting in a steamy room. I use the bathroom with the hot shower going. This drops all the dust particles in the air and elimates static which attracts dust/fluff to the protector.
4. Wash and rinse your hands thoroughly to remove all grease and soap.
5. Clean the PPC screen with a screenwipe then barely damp cloth. The humidity from the steam will help you to get a mirror finish.
6. Wash the protector under a warm running tap until thoroughly clean. Hold by the edges to avoid fingerprints and flick several times to remove excess water. You will end up with a few tiny droplets of water left that you can't shift. Don't worry as these help the sealing process. Don't wipe them off as this will just load it up with fibres!
7. Apply to PPC screen middle first. Immediatley wipe out bubbles by sweeping you finger from the middle to the edges. Smooth out firmly but lightly with the credit card using the sharp corners to expel air and water from the extreme edges.
8. If the protector is not straight, so the screen surround is fouling the edges, DON'T force them down - you'll just permanently distort the film so the edges will never lie flat on the screen. The tiny water droplets trapped under the protector may allow you to slide the film slightly so it pops in place - if not, peel off gently taking care not to bend the film, and start from scratch again - that means right back to the cleaning stage.
9. Once you've got it lying flat, smooth any small bubbles out with the credit card. Don't apply too much pressure as this could scratch or cause the film to move. Instead, use light, repeated strokes.
10. Wipe gently round the edges with the cloth to remove any excess expelled water so it doesn't find it's way into the device.
10. The little bit of moisture under the card will dry out within 24 hours. Resmooth the film regularly in that period with the credit card, to eliminate any small bubbles, or lifting of the edges, that appear as it dries. If you have to use the device, carry the credit card with you for the first couple of days so you can smooth it immediatley before any dust gets under the edges.
11. Keep the backing films in a safe place. You'll need these to gently slide under the protector shoud you ever need to remove it and re-apply.
Result - perfectly clear protector that is virtually invisible.

I also use the bathroom but hadn't thought of the steam - nice idea.
I find it easier to handle the protector by creating a 'T' of adhesive tape which I place on the centre of the protector before removing the backing, that way I can hold it without touching the edges - the opaque scotch tape is the best and can be used to remove the protector too.
Great ideas everyone. Thank you for your feedback!
After trying some more times I got it right with slight dust, hair, bubbles. I'm pleased.
thanx
thank you guys for cool advice, i'll try it soon ..

I can confirm after numerous efforts to get rid of the dust, this is by far the best and most crucial solution-step! I managed a 90-95% success with the protector leaving some openings only at the edges, but in the middle nothing. Thanks for the info!!!

urgent-dead pixels how to fix

hey guys
well i did a mistake by removing the original screen protector. When I removed it, it left alot of residue, so i had to clean it with alot rubbing alcohol.
When i turned the device on i found 2 big illuminating spots on the left and right corners. Does that mean dead pixels or something else?
Is there a way to fix it. Please advice. I tried to rub the areas gently did not work.
Sounds like the symptoms of pressure damage on the screen.
Can you post a picture?

oleophobic coating rubbed off

So I was rubbed the screen with toothpaste to rid of some very light scratches, it worked but the oleophobic coating also rubbed off. I can tell because that are (top) gathers fingerprints very easily compared to the other areas of the screen. Any ideas on how to restore it, or should I just rub the rest of the screen with toothpaste.
WAT?
Do NOT use further chemicals on the screen...you might just have to live with the blemished screen (or replace it). The coating was there to protect, and you have taken it off.
IMHO, just deal.
lolwhat??? toothpaste on a Super AMOLED screen???? thats royally ****ed...you could've got a soft wipe cloth and wiped out the scratches...thats what i do...no chemicals, no toothpaste, no worry
I removed some scratches from my screen using a very very light automotive polish. Worked pretty good for knocking the edges off the screen but I noticed my finger would no longer glide very easily across the screen. It also showed alot of finger prints. I installed a real look screen protector and solved both of those problems. Might want to look into it.

Go into the bathroom,close the door and turn on a hot shower. once the room gets nice and steamy (give it some time) clean your screen with your micro fiber cloth. When you take the protective coating off of the back keep it as face down as possible so any remaining particles in the air do not stick to it ( the steam from the shower clears the dust from the air). Apply to your tab, work out the bubbles, ENJOY!

Put some tape around your finger (sticky side facing outwards). Lift up the screen protector carefully (perhaps in the washroom with hot water running, or another dustfree environment) and use your taped finger to tap the sticky side of the protector where the hairs/dust particles are (sort of like removing lint from clothing). I don't have long nor thin nails, so I used a razor blade to lift up my screen protector. Very carefully, though.
I would advise rolling up your sleeves, washing your hands, etc. so that the chance of dust re-entering the bottom side is minimized. I've done this many times and I just do it normally in my room without any special preparation, but it takes a very long time because every time I use the tape to remove a few dust particles, new ones get trapped under. Eventually, it's just a game of chance to see if I can remove all the dust particles without having any new ones >_>
Thanks

Thanks, hope it works , tried the tape but there are some that just won't budge, oh well $20 down the drain. hope it works, it not , read above.
edit : removed the already applied protector with steamy shower running and used sticky tape to remove dust, went well, no dust particles under screen it now several areas sseem folded, as in that there's no way to use tape or pressure to get rid of it, too saccades to try to bend back, any ideas?

Sealant or adhesive to fix light bleed after screen replacement?

Not sure if I should post this here or someplace like XDA->General, but here goes.....I replaced the glass and digitizer on my G2 and while it works great and looks just fine, in the dark last night I can see clear light bleed from the very edges of the glass and case. I'm more worried about dust getting in than moisture or the light, but it would be great to fix regardless. Is there any kind of opaque sealant or adhesive such as a rubber one could heat and then rub along the edges and wipe off to help seal this area? Thanks!

this may be hard to explain lol, I have a roll of very thin double side tape I bought from ebay. I stick a strip on the outside of the phone, over where I see the light bleed. let half of the tape sticks to the outer edge or the display , and then the other half sticks to the bezel. I then use my finger nail, to work it down into the assembly by tucking it between the screen and the bezel. you'll eventually get it all down in there. then I just take a hair dryer and heat it up slightly. then use even/firm pressure and to hold it down for about 60 seconds. works great! light bleed has been a huge pet peeve of mine since I started replacing screens, the g2 by far is the worse, bc of the almost non existant side bezel (no where to adhere)
That's a great idea, actually. Thank you so much for sharing. I ordered some tape today and I'm going to give it a whirl!
