Hello everybody
I bought a le x820 a month ago and it worked fine for a couple of weeks, but then the screen got crazy and stop working so i got a replacement. The display works but doesn't recognize touch, i tried with another replacemet from other seller and i have the same problem, I thought it was because of a incompatibility from a rom i installed but i got back to a stock developer room and the touch still doesn't work.
Do you have any ideas of what the problem might be?
Heyyo, Hmm that doesn't sound to good! Did your replacement screen come also with new capacitive buttons? Or was it just the glass and no touch digitizer?

Hi,
i bought a used mda via ebay and got it yesterday.
First thing i noticed was that the touchscreen didnt work right... i somhow managed to get through the calibration tool that poops up if i turn the device on. After that the touchscreen worked really good for 1 day and then suddenly it stopped working completely...
Anyone had this problem before and can give me some advice ?? I already got a 20e refund but i want to try to repair the device instead of selling it as broken.
And another question i have: Can i use the wm 2003se on a german device ??
Thank you
Seraptin
Edit: got it repaired myself... I opened the device and cleaned everything... there is still some dirt between the glass and the screen.. if anyone knows how to remove the glass to clean that, im listening But i dont think thats possible anyway.
my screen is broken
Hi,
Glad to read that you have repaired it yourself. I just dropped mine on the floor yesterday and the screen is broken. Touch screen still works but the screen is cracked and I can see a black spot. I wish someone can help me purchase a new screen. I would try to install it myself.

I had rooted the phone and was working all fine. I took it to a store to get the scratch protector installed on my screen and since then it stopped working. The hardware buttons at the bottom are all working fine. I can power up the device. I can reinstall roms but cannot do anything beyond that. anyone have solution for this. I read somewhere that there is some sensor for touch screen enable/disable. Please help. i tried almost everything
So isn't the "scratch protector" the culprit?

I removed the scratch protector screen. still the same problem.
Probably worth going back to the shop you went to? It would be my first port of call...
it happens to me too! the touch screen sensor is broke so you have to go to samsung service to fix it
My phone's LCD was broken, and I wanted to change it. I ordered a new LCD with assembly and connected phone to this one (changed old front with this one). First of them worked well, but was broken after one month, I was my fault. But it already works, touch works very good. In second and third one, after installing touch not worked. But I put it some minutes, then it started recognizing touches. Worked for more than a week, and yesterday night my phone turned off because of battery. Today I charged it, turned on and now touch not works again. When I press to screen hardly or press in somewhere from the back it recognizes touches. What can be problem? I searched about it but all results were about problems with broken glass, but my problem is different.
Thanks...
A few weeks ago i, accidently, dropped my Z2. As a result of this my touchscreen was broken :crying:
My reseller told me that he could sent it to sony but that the costs would be high. App. 200 € ! He advised me to go to a tird party phone repair centre.
So i did. They placed a new touchscreen for 150 €. At first sight the screen works perfect and the colors are perfect. But.... sometimes when i'm typing a message
the screen does not capture my touch? Then i need to touch the screen multiple times to get a reaction. But it's a bit strange. When i'm in my bed with the lights out
the screen captures perfect?? When i use antutu Multi-touch test the screen works perfect! In light and dark conditions!! Is it a hardware issue? A sofware issue.
I tried multiple roms. I tried stock rom. But the problme remains. Anyone who has an idea?
ps Sorry for my bad English!

I work at a third party phone repair center in Lebanon, and from my experience external sources screens aren't as good as the producers screens, 30%+ of the screens we replace got issues.

From your tests you can say its a hardware problem, you can't always expect perfect results from external sources.
I know But it's a bit strange that sometimes it works perfect.
And i just figured out why the screen works perfect at night. When i'm in bed i use the app twilight.
This app filters some light frequencies and dimms the screen. When this app is active the screen works normal!
It seems that it's a brightness issue?
I believe some faulty ICs in the screen are being overheated as high light frequencies are being used so causing the touch layer to stop working.
Sry, for my bad English. But you should check again the store that replaced your screen. :/
hi everyone,
I replaced a new LCD for my Z5 Compact... when I turned on the phone, the LCD lit up and work fine but the Touchscreen isn't working!

Hi Nidhal
I have replaced whole screen with frame, but it seems to be used one (ordered from Aliexpress). It might be the case, I have two complete screens with same issue on my desk, but I dont know how to test them

you have to test each of them separately
take out the mainboard from the old chasis (frame) to test on the new lcd you bought (carefully unplug all the connectors)
then, connect the lcd and digitizer connectors to the mainboard, connect the battery too, and of course the power flex cable should be connected.. power on the phone, and see if the display lit up, then if the touchscreen works... and do the same with the second one you have and i hope you will have a working one al least
watch this video tutorial to avoid any damage

and BTW, never buy these type of parts from aliexpress! would've been better from ebay or amazon because you'll be covered with warranty in case the part you buy is defected, and for that, you'll get a full refund or ebay will refund you if the seller won't
good luck
