Blurry screen after replacing lcd - Xperia Z2 Q&A, Help & Troubleshooting

Repaired my cracked lcd on Xperia z2. Worked perfectly at first but the more I use it the screen becomes more blurry (guessing this is something to do with heat) Starting with pictures but then starting with text.
I bought the screen from China (cud be my mistake)
Anyway to sort this or am I missing something.
If it is the quality of screen is there anyway to lower my resolution so I can use it till I get a replacement.
Thanks for any help

It's probably LCD fault. I don't know how would lower resolution help you, if the screen get blurry. You can try with changing DPI in build.prop file.

Ah rite. Thank you. I think it is the lcd itself.
U say change the DPI
What is this and what would I be changing. I.e (numerical value lowered). Not as clued up on system files I'm afraid but I am learning.

Found out the screen is 380x640 instead of 1080x1980. Really annoyed but hey my fault entirely.
Anybody reading this have a reliable source for buying lcd screens

[Q] AMOLED screen of galaxy s for xperia

Is it possible to put the AMOLED screen of galxy s onto xperia x10 as both have the same screen size?
No because the G S screen is wider than the x 10
Sent from my X10a using XDA App
THen how come both the screen sizes are 4 inch?
4 inches long. Has nothing to do with width

Screens are measured corner to corner. Even if they have the same screen size (4"), unless the aspect ratio is the same the actual length and width are different.

Then which amoled screen suits the x10? wat about nokia e7?
I never got these kinds of ideas... It would be more trouble than it would be worth. Also, you would have to change more than just the screen. Drivers, kernel tweaks, etc.... would all be necessary for you to actually take advantage of it

I'm thinking bootloader access may even be necessary...

Lol yeah they really aren't the same size, plus it would take too much work. Would be pretty awesome though.

Screen Resolution has dropped down!

I don't know why but all of a sudden my screen resolution has gone down.
Everything have a lesser quality to it.
I've read in a topic that you need to Reflash or so a Hard reset... I've change a ROM and it look the same.
Did you installed a screen protector? lol i know this sounds dumb but anyways needed to be asked
I've ZAGG InvisibleShield, but I've placed him before this problem has happened.
The most notable thing I've notice about the screen quality dropping was me being able to see those Transverse lines across me screen when ever I look in black things and in some other colors and parts of my phone.
someone told me something about being able to up grading the screen to 24bit
By any chance can you take an actual photo AND a screen shot of the display ?

That's not resolution, that's colour depth where you end up with banding. Have you installed a new rom, or an update for a rom lately?
Read this and you'll have some more knowledge on the situation:

Sorry for the double post but can someone tell my how can I chane my screen from 16 to 24 bits.
Nothing help with this problem and this is the only think I didn't try doing.
Maybe you can't see a different from an ordinary SGS2 screen, but when I look at the alarm clock notes and a lot of other screen I can clearly see vertical lines when going from one color tune to a more darker one.
Hahahahaha. Dude, everyone with an SGS2 hates the fact that everything is 16 bit. The whole firmware needs to have rewritten drivers for us to get more than 16 bits! It's impossible as of yet.

Vibrant home button leakage

I've been searching on google and on here and can't seem to find a thread on it.
My home button led seems to leak half way into my display when i'm viewing a black screen.
The screen would display a black image and having the buttons on makes the home button leak on the screen
It is really annoying... Anyone else have this issue? it looks like a lightsaber on my phone...

Given where you sent this message from, I think you may be in the wrong forum.
If not, I can't say I've had such an issue, but apart from using a mod to turn off the LEDs for good, there's probably not much you can do.
i'm using my hd2 because I just got my vibrant from Samsung for a screen replacement....
No one has a problem if the led from home leaking?

Exact same problem with the home key, gradually learnt to live with it
How bad is yours? I just need to feel better about it lol
My gf is not as bad as mine

In complete darkness it gets to about half of the screen. In normal light its not as bad.

Yea I have the same problem, My gfs doesnt. I think its a factory defect when they are putting it together. One little pinhole in the paint that seperates the softkeys from the rest of the screen and boom, you have led glare half way up the screen.
I had 3 vibrants replaced an they all had same problem but I dont care buttons are off most of the time
Sent from my SGH-T959 using XDA App
I have this problem but it's very minor. I barely see it when dark. Do they just give you a new vibrant for replacement? Were you able to force them to let you do like an upgrade to a better phone or something?
no they replaced the chrome bezel and the housing + the display and glass...
It's practically new now..

Same exact thing here. The home button leakage is on most(if not all) vibrants. But it's only noticable in near or in pitch dark really. Using 2.2.1 roms turn off the lights while not being used but for some reason, that particular build on whatever rom always decreases sensitivity to the point where going back to used applications(holding home) doesn't work while the processor is being used extensively(800-1ghz) which is REALLY annoying. Anyone else by chance?

Since doing the work it too much, Ilm sure they instead give you a refurbished vibrant and used your old one for parts. In other words, Samsung didn't repair anything for yours but gave you another vibrant(which could be using parts from various sources).
It's the same imei and the same way the home button leaks... I also have a minor scratch on the camera which mine still has

Hardware Display issues are usualy easily seen on a dark background and you have mentoned you see it when its dark

You seem to have a Nexus 4. If you look hard enough, you can see the same lines on that phone too. It's just the screen technology those phones use, it's completely normal.
I understand that but with the Z2 i dont even have to make a effort to see it...
Does it happen to you?

I have a defective unit and no i dont see any lines hence why i said a replacement is needed
The display should be stronger than the avarage human eyes which is 430ppi
Z2 Screen is 442ppi, any lines if existant shouldent be easily seen at all and if any are then there is a problem
I havent seen any at on my phone so id recomend sending yours back for a replacement if posible

I had a nexus 4 and own the Z2 as well. It is perfectly normal. It is the digitiser which is built into the glass screen that you see. If I'm not mistaken, it appears under certain lighting conditions and you can see it at times and cannot at others? It is perfectly normal so don't worry! My N4/Z2 digitiser lines are not extremely visible unless held in certain ways for light to reflect off but my brother's N4 has extremely visible lines for the digitiser! Hope this helps! :highfive:
I've just been to two stores to compare my phone with other Z2's and yes the lines are more pronounced than the others... The funny thing is that my blacks are darker and my whites are whiter... It looks that the screens are different...

Yeah some just happen to have a more defined digitiser but by no means is it something to worry about! That said, you can always return it if it is bothering you though!

Your unit is fine, im 90% sure its just the backlight (its strobes so looks like white lines on a dark background.)

It's not like that. The LCD it self is good and i don't even have dead pixels.
What i see is this:
"Polarizer lines"
I think i'm going to return it. With low light it's ok but during the day i can see it very well.
This is the second Z2 that i return. The first one had a tinted red display.
I bought it on a Uk online store that i'm beginning to suspect that is selling second quality items...
Yeah you might have a more visible polarizer on your unit which magus alot of sense

Actually funny you mention the polarizer.
I noticed these odd dotted lines on my screen and freaked out....
Polarized glasses.... turn my head 90 degrees and all was well... haha
Those dotted lines are normal. If you've seen mine you would freak out believe me... Lol

I would replace the screen cause your example of a phone is one of the worst you could of picked......which has bad malware issues along with lag (due to screen resolution) and overheating issues (due to screen resolution again) and max brightness is terrible
