[Q] Screen Issues - Xperia Z1 Compact Q&A, Help & Troubleshooting

So a little while ago a friend of mine broke his z1's screen. We went and got a new one but because we wanted to save a bit of money we went and got one from a chinese site. Now I have just installed the screen and it works pretty damn well but there is a bit of a problem. The phone isn't showing the touches where they should be. they're accurate on the left side but as you go to the right the touch location lags behind your finger. This is probably just the digitizer being a bit cheap and crap but seeing as I just installed the screen with adhesive and all is there a way that we could modify the touch calibration to get it in line? Note here that the phone ISN'T rooted although if the solution needs it we certainly can root it.

[Q] Xperia arc screen too sensitive?

Hi all,
I simply love this phone, but I'm facing a situation that my screen is too sensitive. The home screens were so sensitive a few programs were started without my knowledge. It got better after I switched to Launcher Pro.
However, it is still too sensitive in other areas. When I'm scrolling down, say, the apps in Market, I'll always end up selecting a few items accidentally before I reach the end of the list.
I've used HTC Desire in the past and I'm quite sure the problem is not due to me.
Does anyone else face the same problem, or I have a hardware problem? Or software problem? Can I be tweaked by any means?
Any feedback would be useful! Thanks!!!

I faced this problem before... while swiping, apps accidentally open. But instead of "too sensitive" i thought it's insensitive... because a short swipe was sometimes interpreted as a tap (maybe because the swipe was not fully detected?).
Anyway, I had 2 layers on my device... the pre-applied sheet and another screen protector that came with the box.
I removed the second layer, leaving only the pre-applied sheet, and all is well again... no more accidental "taps"

Dude, you mean the cause was the screen protector that came with the phone???

For my case, maybe 2 layers is just too thick
I'm having the same problem. And that solution seems to make sense. I would give it a try, but if the problem still occurs, I'd be wasting one screen protector..

That was how I solved my problem. I actually put on the spare screen protector because when I got the set I didn't realize there was already a pre-applied layer.
Don't blame me if it doesn't work for you
perhaps some of you guys just have the shakes?! ;-p
I guess the screen is never to perfect for everyone.
kargtan, I've noticed the same about the tap sensitivity - I often accidentally "tap" when I mean to swipe. Came from an iPhone 3g and didn't notice this on that device. Might be a matter of getting used to it, not sure. Have you gotten any feedback from others in other forums?
I've noticed this too, and put it down to the screen protector. It's not android OS causing it, never had the problem on my htc hero...
However, now that i've gotten used to the phone it doesnt do it any more - guess my brain has automatically trained itself to drag the screen a little bit more firmly or something.
One thing i have noticed about the arc is: because the bezel around the screen is so thin, i often accidentally launch apps just by holding it. My fingers wrap around slightly & touch the edges of the screen.
Does any of you have problems while trying to swap a screen from another and instead of swapping you get like a "bounce" and stay on the same screen? because that happens to me all the time, I came from an htc Legend and this is making me crazy !
btw, this happens to me if I hold the phone with my right hand and try to do the swapping with my thumb, the only way to get it right is to hold the phone with my left hand and use the index of my right hand
Screen too/not sensitive
Hi guys,
I think the problem arises from the slowness of the phone, not "too sensitive". I used to use the HTC Desire in the past and I was very used to the screen scrolling very quickly. In contrast, the arc is slower and hence the screens don't scroll as fast and hence my way of handling the Desire would cause the problems stated.
I did a few things since my last posting and it seems better now:
Replace the SE Home with Launcher Pro - this seems to have improved on the speed of the phone, and hence better responsiveness to the touch.
Rooted the phone and uninstalled some stock programs.
Removed useless widgets on the desktops.
Adjusted my way of scrolling as someone has suggested.
This is quite frustrating at times, especially so because other than this problem, this phone is a gem, especially its form factor, the sound quality and most importantly, the quality of the camera.
I might sell the phone once the company issues me with a Blackberry (DANG!), but I am kinda unwilling because I have been taking lots of photos with my Android phones and these photos are generally well-liked by my Facebook friends.
agree with bezel thing and hard to use thumb.
noticed arc screen (the screen guard perhaps ) easily get oily and slippery.
had to wipe phone and wash hand so often that make me like some sort of disorder.
Don't know why you guys seem to be having problems... I don't have any issues with my screen swipes at all... smooth and fast.. both on stock and Launcher Pro..
Same deal here. But that's because the screen is sensitive beyond the display area including the black border, and the edge is too narrow. When I use one hand swiping or tapping, the palm of my hand touches the black border. The screen registers two touches in quick succession and thus jumps.
In Phone keypad, enter *#*#7378423#*#* (the numbers mean SERVICE word in keypad), you can go into test mode. Select [Service test]->[Touch Screen] to test the badly touch screen of SE Phones.
You will discover when you swipe the edge of touch screen, the touched result is very not satisfied. The lines you swiped will not accurate and appear like jags, or stick on the edge of the screen.
The touch panel made in China...? ;-)
Me too!
Hey!
i also have a xperia tipo....and i too have the sensitive problem
Could also be a kernel problem?
I remember I installed a kernel a while back that would make my screen hypersensitive; just hovering over the screen would already activate it!
I don't remember which one, it was back in the GB days. But I'm pretty sure it can be changed in the kernel.

Digitizer Problem

My touch screen recently stopped working on the right hand side of the screen maybe about 1/4 of an inch of it. I purchased a new digitizer installed it and now I have the same problem but on the left hand side of the screen (yes i installed it right side up you can only instal it one way). Is it possible the replacement also has a problem or is there something wrong with the digitizer processor(not sure if there is such a thing). I also took it apart and cleaned the jaw bone connector but I still have the same problem.
Thanks
Im sure you tried this but try reinstalling the stock rom, not just format, it could always be a software problem depending on whats broken.
Ive had colored bars across my screen from buggy roms thinking my screen cracked/broke.
Not saying this is the exact issue you're having, but I did encounter a similar problem with my OG Droid. I bought a cheap replacement digitizer off eBay for an issue exactly like yours. When I installed it, the problem was actually worse than before the replacement. I bought one from a better reviewed manufacturer on Amazon and it worked like a charm. So I would say there's definitely a chance that you just got a bad replacement. They do seem to be somewhat fragile by nature.

[Q] Did I get a defective replacement screen? T217S

My wife got a new phone 3 weeks ago (Samsung S5) and in the process was given a "free" Samsung Tab3. Last week the tablet fell of a table and the screen cracked so I decided to play Mr.Wizard and replace the screen. Got the replacement screen, saw the video online and all went pretty smooth. Turn the tablet on and all is still well. Then am trying to set up her e-mail and notice that the 1 on the keyboard does not work. I downloaded an app called Simple Touch Screen Tester and come to find out that the part of the screen where the 1 would be (in portrait mode) is not responding to any touches. If I press down hard on the screen some areas do respond but not all.
Is it possible I got a defective screen? Would spending another $ 20 be worth it?
Or should I return the tablet to Sprint (I assume it is still under the 30 day warranty) and not mention the fact the screen cracked and I replaced it? Can Sprint tell I replaced the screen?
Thanks for any help.

Since you already replaced the dig, you know what's involved. If you're good at what you do, then Sprint can't tell. I've had a Samsung tab with a dead band within which no touch would register. Sent it to Samsung and all they did was update the firmware. But it can be hardware-related. If you bought a replacement lined with tape, it's possible the back of the digitizer didn't stick evenly to the frame 'cause you did not clean all the glue residue before. That certainly can cause problems. Then you may want to check the connection to the motherboard. It should click when you snap it on correctly. The way Samsung digitizer are built, it doesn't feel like yours is defective. I've had one that literally was smashed to pieces yet persisted.

Cracked screen

Hello!
Today dropped my phone and screen got covered in spider web. The display itself looks fine, but its covered it spiderweb. The touchscreen doesnt respond at all.
What do i need to do now? I looked at local repair shops, they ask atleast 100 euros. But on ebay i can find lcd display+screen digitizer for 55 euros shipped, or screen digitizer starting from 10 dollars!
Can i buy only screen digitizer (as i understand that top layer of glass thats cracked is screen digitizer?) and replace it? Or changing LCD display along with screen digitizer is a must?
http://www.ebay.com/itm/NOIR-VITRE-...Pièces_de_rechange_outils&hash=item27f98e5d31
So this should fit..right? And are all 3 models LS970, E975 and e973 really same size? Cuz i`ve read people have got smaller screens than original from some sellers on amazon.
Replacing a digitizer is pretty hard and time consuming, that's why people usually replace the whole lcd+digitizer+glass assembly. You will also need adhesive and a heater/appropriate tools. It can be a great learning experience if you don't mind potentially busting your phone. There are no shortage of instructionnal videos on youtube on the subject.
Also, a new G2 is only 190$US .... Just saying ...

As i have two other phones. The g2 mini with Tegra and a razrHD. I'll give a try, thanks for the tip.
Well, i ended up ordering that LCD+Digitzer from ebay. Everything was fine for 2 months, now i have quite large spot that doesnt respond to touches. (See attachment) i already tried disconecting the lcd and digitizer..still same. Is it worth trying to flash another rom? I already flashed stock kdz (had stock before too..)
This happened just today, right after ghost touches went crazy and rondomly oppening everything.
EDIT: That spot is changing sizes..form remains, but it got a bit smaller now. Its truly weird. I put the phone outside for few minutes (its +9C outside) and touchscreen works fine now! What is going on?
EDIT 2: After few minutes of usage, the spot is coming back

I had dropped my LG (more than a couple of times) on its face and it seemed to suffer stroke-like symptoms: one side of the screen was completely dead to touch, and the rest of the screen would occasionally act as though I was touching everywhere which opened programs and messed with the keyboard. I was stubborn and just lived with it and over time, it stopped trying open programs and whatnot. Recently, dropped it again, this time it was a bit more serious. Still no visible damage to the screen, but the "dead spot" moved to the centre of the screen, and again, occasionally tries to open programs and add words to my messages.
At first I thought it all could be related to a software issue. Unfortunately, after installing new ROMS, it never fixed the problem. I bought a digitaliser screen from Ebay as well. I'm waiting on the adhesive tape still so I can't say if this will fix anything. I kind of have a suspicion that its a loose connector (the top middle part of the screen gets super hot only after a couple of minutes of being left on).
I'm just wondering if you have tried taking it apart again to recheck the wiring? I think we may have similar problems (your situation is the first I've come by on the internet that is anywhere close to what's happening to my screen). Thanks so much!

Screen peeling off beneath the glass...

Guys I need help with this.
On may I sent my phone to warranty due to the faulty motherboard that killed my phone. The second day I got it back I noticed a small golden spot in the screen but I didnt really pay attention. I got used to it and I really didn't notice the spot going bigger. I quit my job so I kinda stopped using my phone like I used to, now I just load WhatsApp from the browser and thats it.
During july I noticed that the spot became even bigger and just the day I lost my 1 year warranty the spot became even bigger and there was a second one. Today I noticed a new one. The thing just happens overnight... WTH??
It's like the screen is peeling off beneath the screen, if I push it down it kind goes away while keeping it pressed but if I remove the pressure the spot comes back again.
Why is this happening? I don't want to replace the screen just to have it happen to me again specially since the screen will cost me a lot to replace here in Mexico. Even if I buy the screen myself from Repair Universe (is it safe?).
Is this humidity?
Yes it is humidity my friend. Friend's G4 has the same problem after he droped it in water, just his marks are REALLY BIGG
Dang it!
The replacement is $85USD but Im not sure if I should change it right now, wait or probably get a new phone
Thanks!
