[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.

Turn down touch screen sensitivity?

Hi All,
Is it possible to turn down the touch screen sensitivity on the M8? I am finding that I do not even have to touch the screen in many cases and as a result the phone is doing a lot of unintentional things. Its especially annoying when texting as the phone registers a press as soon as the surface of my thumb comes near the screen, which might not be the area where i'm actually pressing. I had the same issue on my M7 too but didn't keep the phone for very long.

I'll bump this, interested myself.

I'd try using a screen protector. The M8 screen is propably more sensitive in order to work with the flip cover, which adds a quite thick layer to the digitizer. In order to actually decrease the sensitivity, you'd propably have to modify the touchscreen driver.

I have an otter case which has a screen protector, and the sensitivity is still outrageous.

This annoys the hell out of me too. Such a shame as I've just come from an iPhone 5S and prefer almost everything about the M8. It's only this and the slightly underwhelming camera that annoy. I'm still happy I switched.

Also have a screen protector - a glass one, 0.3 mm. I barley have to touch the screen, what's more, could have sworn a couple of times I haven't actually touched it. Ha, a microfiber screen wipe is enough to unlock the phone but since I turned off motion launch gestures I can live with it .
edit - maybe the "gloves mode" that's available in other brand android phones is on by default?

[Q] Touch sensitivity / registration issue !

Hello everybody, I just received my g4 yesterday so I had it now for 24hrs and sometimes soft /light touches does not register and I find myself touching the same icon again to make it work .
Coming from Galaxy S6 it seems the G4 sometimes skip a touch or two.
Is that normal? Did anyone else noticed the same ?
Can this be corrected by software updates or is it something wrong with my G4?

Press harder?

Obviously this is the solution but comparing to GS6 and HTC m8 this was never an issue so I am sharing my experience with LG G4 to compare and to find out if this is isolated case or mass issue !

The G4 does not run on super amoled, obviously. The review units seem to have the same 'issue' when compared with other phones. It's the type of screen.

Appreciate your feedback

I just picked up my G4 today and am noticing the same thing. My Note 4 had a setting where you could turn up sensitivity, I have yet to find it on this phone

Give this app a try https://play.google.com/store/apps/details?id=br.shop4apps.touchscreenbooster.com&hl=en I installed it and set it to Super Optimized and it seems to be making the sensitivity a little better. I am coming from the S6 so it was driving me crazy with all the missed registrations.

I'm finding it to be the opposite. While scrolling through my app drawer I end up starting up an app

I'm having the same issue, however I am running a Mime tempered glass screen protector. My cousin has also reported the same issue where it is missing taps, he's running a Zagg tempered glass screen protector.
To those with the issue are you also running a tempered glass protector?

I have a tempered glass screen protector. I did use the phone for a day or so before I started using the protector. The outcome has been the same for me either way. 90~95 out of 100 taps and swipes are registered properly but the 5 to 10% missed taps are starting to get really annoying for me. Most of the time I won't notice or care in a non gaming scenario though.
I have used the app posted above and it doesn't seem to really make a difference for me. Very frustrating because everything else about the phone has been great (battery, camera, screen, sound, etc). Debating if it's worth rolling the dice on a new phone.. We are in 2015 and this shouldn't be happening, last time I had a phone that missed taps was like 2011.

I was having a similar touch issue. But I fixed mine--or resolved it. I discovered it while scrolling through the reddit Sync app. I would have to press links twice because it wouldn't register the first time. Then for some reason, I discovered the issue:
IF the screen is moving (as in still scrolling from a swipe) ANY AMOUNT at all, the first touch does not open the intended link/target. Even if the screen scroll has slowed to an absolute crawl, but isn't COMPLETELY stopped, the first touch only 'stops' the screen. If I wait to touch until the screen has come to a complete stop, it works every time. Maybe my previous phones didn't have as tight of a tolerance on how much the screen can be moving before registering touches.
Other than that, the screen may be slightly less sensitive than other phones.
Not sure if this is the same touch issue you're having, but I hope this helps someone.

I came from a Galaxy S3 and have the same issue. It's driving me crazy!

Just to add to the topic I've come from a Nexus 6 and I'm experiencing the same issue. Definitely missed taps.

I am assuming the N6 does not have touch issues like this... I am going to be jumping to it from the G4, I think this is just an unacceptable phone. How is the size / handling of the N6 compared to the G4? That's my only concern...

Honestly I've had every Nexus device and the Nexus 6 I wasn't the biggest fan. It had none of the touch screen issues but the camera was not on the same level and in my experience neither was the battery life.
I also much prefer the size of the G4 and I'm not a fan of AMOLED screens I can't stand the black ghosting that occurs on them.
I've already contacted the Three store here in the UK where I got my G4 and they are happy to exchange but honestly I won't be switching from the G4. We just need more people like on here to make themselves heard and hopefully LG come up with a fix or it comes down to a bad batch.
That's not to say the Nexus 6 is a bad phone but if they can fix the touch screen issues on the G4 there really is no comparison in my opinion.

This was brought up by someone else, but for those that feel the touch sensitivity / registration is not workigng so well, do any of you have a screen protector? Whether it is Tempered Glass or a Protective Film it could be inteffiring with the display?
Also, if you are having problems and have something on your screen for protection, what type of protection is it and what brand? Just figure it is worth a shot asking and seeing if there is a pattern.

I'm using a CaseBase Tempered Glass Protector but my other half is rocking a naked G4 and the issues are still present. I actually already have another Protector on the way from a different manufacture because I initially thought that it could be the problem.
Then I began reading on here and Reddit and discovered we are not the only ones with the issue.

No screen protector for me.

No screen protector here either... it's just super frustrating to have a flagship phone perform this poorly.

I'm actually experiencing both the issue in the OP and the issue you're having where I try to swipe to scroll but it ends up tapping instead, though they happen at different times. There seems to be something wrong with these touchscreens since it seems to be a common problem.

Touch too sensitive! issue?

I've tried to change the touch feedback setting to long/medium/short but nothing changed.
I attach a video that show what is the problem with the screen/digitizer - when tapping and keep touching (holding) the screen look at the X axis - its not constant as it should be.
The finger hold stable and not moving, but at the screen the dot moving.
I've checked 3 other G4 devices, all of them don't have this issue.
There is no screen protector (neither the one that comes with the device)
Most of the problem is at the top left of the screen, the bottom right is pretty stable.
Its very annoying while use brush/paint, zoom pictures, playing horizontal mode the left side (top of the screen) dosn't work because of this on some games.
Anyone else had this issue?
What is that problem and how do I fix it?

Is it a software / hardware problem?
There is something to make it better? anyone notice this issue?

My g3 was real bad like this it was software changed from kernal to kernal. not really rom to rom. And g4 is horribly over sensative

I have the same problem, for me it's probably hardware and software, because it was better before V20D, but I still had the problem, now it's worst. LG tried to hide this ****ty screen with software. But I repeat it's first an hardware problem... All my left screen is bad and not stable, more than yours.
Try the app "Ghost Touch Tester" and in developer mode activate "Show Touches"

This is very disappointing, reminds me the first android devices at 2010 with the bad touch screen.
Its not that worst, but you expect a smoother and better quality for device on this level.
I guess its a hardware issue, 2 other devices that I've checked dosn't have this issue (of too sensitive touch) even with tempered glass screen protectors.
The left and the top sides are most sensitive then right buttom.
Maybe kernel would fix it, anyway same story with ver. 5 and with the new 6.
Any ideas if there is something to do?
Have a 2 years warranty but I believe they "won't find any problem".

My g4 is pretty bad when trying to type i mispell all kinds of crap and i got the glass on too

My G4 is very difficult to scroll with. It constantly opens links, instead of scrolling. Tried changing the Acessibility settings for response time to slow, and also the pointer speed, but it didn't work. Very frustrating. I almost wonder if someone paid LG to make sure more links get opened. Seems kind of convenient that the end result is you click on almost every single link.

active stylus partially functioning.

So i bought the a50 cause i wanted a bigger phone like the note at a cheap price. Loving the phone, so i decided to spring for an active stylus, the stylus actually works very well on my g6 and dell touchscreen but for some reason the upper half of my a50 isnt very responsive, and where it does respond is only on the edges. If i start a stroke from the bottom of the scren it will follow through to the top, most of the time. But if i start at the top and move down, it only appear towards the bottom off the screen. Tapping is even worse, almost no response on upper half.
I have no magnetic cases, ive tried two a50s, with and without screen protectors. Always the same result. Heres some pictures to help visualize, does anyone have a fix for this?

Scribles represent dragging, dots represent taps.

You could try increasing the touch sensitivity.

Thank you for your response. I should have mentioned, the problem is identicle, with or without touch sensitivity increased. The stylus work on a note 9 perfect as well. Starting to suspect its a software problem with the a50.
