Bad ghosting after screen replacement - Huawei P9 Questions & Answers

Hi all. Hoping someone can help or she'd some.ideas to me.Nottingham
I replaced the screen on my eva-l09 and had issues with it ghost pressing and then the front glass lifted off. So brought another screen (and frame) and again getting really bad ghost pressing and generally going mental.
Both screens were ebay so appreciate may not be best but for it to happen to two screens sseems odd.
Problems I have are random mental press in and scrolling. Phone is seen my finger press as got cursor showing but not actually pressing app icons or scrolling.
Of I hover finger close to screen it sees it despite not touching it.
If I press at very bottom the cursor shows at the very top.
I also only seems to do it in a few certain apps.
I've turned brightness down, cleaned it and made sure no processes are being closed by battery management.
Am I missing something really oblivious or is there an issue with the main board?
Any help or advice greatly appreciated
Cheers

Touch screen issues...

So I am wondering if any of the wonderful people here at XDA are experiencing screen issues with the nook color. I have had my unit about a week, and have had numerous episodes of the screen registering touches randomly. This issue is apparently not isolated as there are youtube videos and a B&N support forum thread discussing the matter.
So is anyone out there having any touchscreen craziness? If so are you doing anything about it? Not sure if I should return my unit and get another or wait for some possible firmware update...
As always any wisdom is appreciated!

Says at the top recalibrating will fixes "phantom touches" or inaccurate touches, or not respond to reasonable touches.
Mine was doing the same. I bought a screen protector and so far it hasn't happened.
My screen wasn't having "phantom touches," but at times I would press near the top and bottom edges, it seems to not be very responsive there. For example, pressing the search button in the marketplace that's at the very top right. Or pressing one of the buttons at the bottom menu.
I wiped my device back to factory and then did the latest Auto-Nooter, and started using Go Launcher. Things are much better now it seems. I think it may still happen occasionally though.

Not just the phantom but inaccurate touches which sounds like yours, atm thats all ive seen about fixing screen stuff.
But other threads have been started where others have the same problem on the outer parts of the screen so it could be a Firmware/Hardware problem.

works for me, in that the process completes, but the touchscreen is the same. The sensitivity issue at the edges is universal and very frustrating.

[Q] Top of screen very unresponsive on new NC

Hey
Just got my brand new NC and for some reason the top part of the sceen just won't easily accept input.
It took me almost 100 tries to activate the slider in setcpu.
Any ideas. ?
Thanks Pavlos
You can try this:
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen
Did this work?
Yep tried that to no success.
Anything else?
Also just noticed in Market that I cannot see any payied apps.
I too have had a lot of trouble with the top edge of the touchscreen, luckily I don't use it too much so it doesn't bother me.
All 4 corners of the screen are very unresponsive for me.
For example, on the new Market, I can pretty much NEVER hit the search button in the top right corner of the screen. I have grown accustomed to pressing Menu then Search instead of using that on-screen button.
Is this not how everyone's NC is?
Mine is not as responsive, but I do not have that bad of a problem with it.

You suggest thats unfixable....

in my case the newer market search button works a lot better than the previous one. still, far from great
Ive had the same exact issue. And can be replicated if you turn the device upside down, all 4 corners have to be touched multiple times in-order for it to register.
best way to test is in portrait mode and trying to hit the search button, tap once a second, unresponsive.....4 times in a sec and it will highlight once.
download the lcddensity app in the market place and change it to 180 that worked for me
Not exactly sure how changing the lcd density would fix this....downloaded anyway...applied...still doesn't work
What is funny though is that TouchTest the screen is insanely responsive on all areas on the screen from edges to multitouch. So im not entirely sure what the deal is.
Sometime I have to apply a little pressure to the back of the nook to get those parts of the screen to work. Pressing the bezel a little also helps. The larger density will make buttons easier to press because they are bigger. Small buttons/icons at the corners/edges of a screen are a pain. I bumped mine up to 240. Nice big juicy buttons.

I have the same here. Corners not responsive.
Not a big issue for me.
I also have the screen protector on.
Corners here also. Irritates me every time I try to search market.
Both NC I have used have the exact same sensitivity issue. It may just be part of the stock NC Kernel that is causing it for some odd reason. It is not completely impossible to work with but it is a bit of a hassle. It is really apparent in the Astro app manager/backup. When you go to check an app to uninstall, it takes like 20 taps to try and check the box to uninstall an app. Odd how it gives me trouble there but in other apps it has no problem whatsoever. Software based issue it feels.
The response from edges of screen is my biggest irritant when using the NC. It did get a LITTLE better for me when I did the recalibration linked to in 2nd post with my NC laying flat on a table with the lcd facing down.

HAHAHAHAH me too!!! I just figured maybe soft keys rendered the actual market search button unusable or something. Wow....well, hopefully it won't start to annoy me now that I know it's supposed to work

Touch Screen Sensitivity...

Anyone else having problems with the sensitivity on fast scrolling? Seems to not be as smooth or compared to the iPhone 6 and HTC One M8 I have been playing with...It's almost too sensitive or something, I can't quite put my finger on it.
Do you mean the effect where things sometimes bounce back while scrolling?

There is an earlier topic about it here: http://forum.xda-developers.com/z3-compact/help/swipe-issues-t2888154
The phone has an extra-sensitive touch screen because it has a "glove mode", and I'm thinking the effect of the technology for that glove mode isn't completely suppressed when the glove mode is disabled, so the touch screen would still be slightly more sensitive than those of other phones, even when glove mode is disabled.
If glove mode is enabled, the touch screen is so incredibly sensitive that without gloves, it will register a touch when you hover your finger about a millimetre above the touch screen.
I found that for me it helps to use "lighter" and shorter swipes. Also after a swipe lifting my finger a bit higher off the screen than I was used to.
Some people might always have been doing shorter and lighter swipes, hence not everyone is experiencing the problem. It's also been said on the Xperia support forum that not all units use the same glass for the front; some use "gorilla glass", others use "dragontrail" glass. That could also be influencing the touch screen sensitivity/behaviour.
I've adjusted my swiping habits relatively quickly and now I get the bounce back effect only once in a while.
I do hope that Sony comes with a firmware fix to compensate for the over-sensitivity though.

hi, is it normal? happen to my unit also.. quite annoying i can tell.. different with my TX..
Go into developer options and enable "Show touches", perhaps touch the screen a few times then turn off show touches.
Sorts it out for me! I was having a nightmare swiping down to select words in Fleksy.
This workaround will do for me until Sony fix it properly!

I really wish there was a way to turn down the sensitivity. During typing, I frequently have screen presses register as very short swipes, which is incredibly irritating, as I then have to backspace and delete two words.
Not really helping you, but this shows how sensitive the z3c display is:

Touch screens usually respond to metal. The screen of my Z2 tablet does.
My screen is so sensitive I can operate it using my leg... through the pocket. I saw in Z1 and Z2 threads that there is a config file that can be adjusted, however I'd have to root in order to do that, and I don't want to risk losing my warranty (esp. not when reading about glass breaking by itself).
It's not a massive problem -- all it takes is switching off "double tap to wake" and camera launch button. But those are features that are useful. On the other hand, having my phone suddenly switch Torch on, call a random person in my phonebook or reorder icons on the launcher desktop isn't all that exciting either -- not a fan of surprises.
Has anyone else found the Z3 Compact screen too sensitive? (Glove mode is off, obviously.)

On my previous phone (xperia acro s) it often happened that my leg messed with the phone when the screen went on for the alarm going off in my pocket. It was really annoying. I was always afraid that some important settings changed without knowing it.
My screen is so sensitive that I the last couple of weeks only have managed to send a few sms without having to delete several words that are written wrong...!
The speeddialer is also terrible and often leads to wrong contacts...
This phone is by far the worst phone I have ever had regarding these issues!
Is this a sign of a faulty phone or can you relate to these problems as well?
Is there a solution???
My speed dial wasn't working out of the box. Had to make a factory reset, that fixed it. Sensitivity isn't interfering with my writing though. My previous phone was a bit bigger so I had to get used to writing on a smaller keyboard. But why would touchscreen sensitivity be an issue when writing anyway? Are you using a swipe keyboard?
No I'm just using it out of the box settings...? I can see swipe is enabeled but I text normal... I have had to disable autocorrecting words when I write... It is really strange... I have had many different smartphones over the last 15 years and this is by far the most responsive ever tending to be useless because of the many mistakes I make during calls and sms...
I never had any issues what so ever with my M7...?
I have just disabled "motioninput" (roughly translated from danish...) under Xperia-texting and this seems to have helped alot!!!
I'm on the same boat - it's too sensitive compared to my m8. Hoping for update to fix it
You really should try to do what I did and disable motioninput! It really helps ??
I'm on the same boat - it's too sensitive compared to my nexus 4. Hoping for update to fix it
I go into running apps and force stop com.sonymobile.touchscreen.touchfilter.tfpss and it seems to be a little better, still sensitive but at least no bouceback. I should try pm blocking it.

I've tried this as well, but unfortunately no change, I still get bounce-backs when I don't use particularly light and short swipes.

Does anyone else have an unresponsive touch screen?

I first noticed this on a running game where you have to hold down either the left or right side of the screen to move in that direction. It would usually register the first press, but not that I had held my finger down so I wasnt moving properly. I thought this was due to the game it's self rather than my phone.
I've just downloaded Naugh where you have to rotate the screen by touching either side of the phone, and again the same issue. It's really unresponsive - It will recognise the tap but not that i've held it, it will stop working. Occasionaly this will also happen when scrolling a page.
I did a quick google search and found that the Z1 had this issue, but havent found a fix.
Has anyone else experienced this? Or if not, any suggestions on figuring out whats wrong?
Edit: I recorded a video of exactly what I mean: https://www.youtube.com/watch?v=UW2gCWpThWc
I don't know if my problem with my screen is related to yours, but i'm experiencing some problems as well.
On the picture i attached in this post is a picture taken of my screen with a black background.
In the middle of the screen there is a slight discolouring, and in this particular spot the touch screen is very unresponsive, i'm especially noticing this when playing candy crush, making it almost impossible to swap the two candies in this particular spot
Both of these sound a bit like my problem was at first, but mine quickly got worse (in hours) and then I found the hairline crack in the screen.
Bottom corner and not in a part of the screen that displays anything - just the 'glass' front at the bottom - but a third of the screen near the middle doesn't respond to touch.
It gradually got worse over a couple of hours until it stopped responding altogether.

[Q] Hyper sensitive power/lock-button

Hey, recently I bought a Sony Xperia Z (C6603) off ebay. The phone is working fine so far, except for one thing:
The power button is VERY sensitive. If I only swipe over it with my finger, it treats this already like a press.
Comparing it to my other C6603 (I want to give on of them to my parents) with a working power button,
I can see that the working button sticks a tiny bit more far out than the overly-sensitive one. Also, the sensitive one doesn't give that typical "click"-feedback when pressing it.
Not only do I fear that this would accidentially turn on the screen whilst being in my pocket, but also it's a bit irritating while actually using the phone (initially I thought that the LCD was defect until I realized that it's only flickering because my finger touched the button lightly).
Has anyone else experienced this and/or knows a solution? I guess since the device is waterproof opening it (and closing it after) is bit more of an effort and is thus not too advisable. But who knows.
With the case on it's a bit better but still an issue.
tl;dr: Power button is VERY sensitive, is there any easy fix?
Also, is there any app that could tell me how often the screen got turned on during the phone was in my pocket? Just to know how much this is an issue.
Thanks in advance!
