KF Touchscreen Sensitivity Issues

Hello everyone,
I have been playing with my Kindle Fire, since I got it, and I am about ready to chuck it out the window, or just call Amazon for a new one, but I first wanted to see if you guys had any suggestions. My touchscreen is oversensitive. WAY oversensitive. Oversensitive to the point that if I have to type anything into the keybaord, I will be three letters in, the keyboard will close, and I will have to start over. So sensitive/messed up that when scrolling an article in landscape mode, using only my left hand to scroll, random links will click on the right side of the page. The opposite happens if I do it with my right hand. I like the device, and look forward to rooting it, and ICS goodness eventually, but I wanted to know I have a dud and need to return it, or if there is some hidden setting somewhere or what. I am open to trying anything. Side note: I also own a thunderbolt, and find its touchscreen too sensitive, but nowhere NEAR the KF. I am making sure to make deliberate presses and swypes, and trying to make sure no extraneous part of my hand interferes at all. (sometimes even using one hand to poke at the keyboard with the device sitting on the table will still produce the problems.)
Thanks for the help!

Hey Brock!
I've noticed that my screen is a little more sensitive than my epic 4g but not to the extreme you are talking about.
Perhaps your screen is bugged or something try calling amazon and see what they say.
Also as a side note try rubbing your hands over the screen smudge it up pretty good. Does that make a difference? I know it will look ugly but maybe there was a film or something on the screen. Just to test
*forgive any grammar or spelling mistakes I injured my right hand and it is hard to type with bandages *

Hi
I have a bunch of problems too. Mine is sensitive, and its sometimes a problem not overscroll, but yours seem to be extreme.
As a way out, if you have time drop by a BestB** and try it there, if yours is the same, not to much left to do....

I've been using mine all day and I don't even need to touch the screen. If I get my finger really close to the screen it reads as a touch. I'd say that's a tad too sensitive.

They are all like that. Its because the touch screen is capacitive. My Screen at work does that.

I'm having the opposite problem...I'm finding the touchscreen not sensitive enough....

Same here, I feel like I have to push the screen really hard to get it to register. I hit the screen lightly and it does not register my touch. I'm used to my EVO 4g, maybe it is just a lot more sensitive than the fire.

Same here, but it's not as simple as it not registering the touch. Most times the button will animate to show I've touched it but nothing happens. It happens most often with the back button, but happens in the browser and some other apps occasionally. I've had some luck with slower more deliberate taps, but it seems like a software bug to me.

I was using my mom's so I could teach her how to use it, and see if I wanted one. Her was also not sensitive enough many times. It wasn't just that I am used to my Droid 2 because my mom who never used a touch screen before had the same issues. Sometimes it would take 3 or 4 taps to make it work. I just thought it was a bug that would be fixed. It was minor. I ordered my one, so on Tuesday I will see how mine is.
OP I say contact tech support immediately.

My screen is fine, the only problem I'm having is the menu gets pressed, it shows that it was pressed but nothing happens

The two kindle fires I've used have the same touchscreen issue: there is a jerk (along the longest direction of the screen) on touch down. Once the finger is down the reported position is fairly stable, but the initial touch down needs to be smoothed out (or the first few samples from the touch screen should be thrown out).
This causes most of the issues I've seen on mine, where pressing buttons is either inaccurate or they go down and come up without activating (because the touchscreen reported a touch down inside the button and then jerked out of the button area and reported a touch up).
I've spent way too much time on touchscreen drivers (way too much!) and this is a fairly common electrical issue, and the software workaround is fairly straightforward to implement in the kernel. It's surprising that Amazon shipped the device like this (as well as various SGX drivers issues on some apps), especially as every review mentioned it as an issue!
Anyway, once we can build and flash kernels reliably I'm sure we can fix most of the touchscreen issues.

My kindle too !!!
Because of this, I'm getting very stressed ㅠㅠ
It's a matter of the touch panel... would be fixed by software?
If this is not possible... Then I'll be selling the Kindle

I downloaded an app called ILITEK Touch Utility which appears to have made my touchscreen work better. It is in the Google Market.

I'll have to try that out, would be nice to tweak it some Thanks!

mine is not too sensitive, sometimes i have to press multiple times for it to register

Bumping this thread, because this issue is annoying the hell out of me. Those having the touchscreen not being sensitive enough, it's the same issue as those finding it too sensitive. The problem in reality is that it's ridiculously sensitive, and as your finger presses down on the screen, it's sometimes reading that as an attempt to swipe/scroll rather than a tap/press, which is why you see things light up still, but not launch.
This is frustrating me more and more as time goes on. I've tried this, which I can tell adjusts some of these settings but doesn't really make much difference for the problem. I've also tried this, which didn't help any after calibration.
Some people have speculated (or confirmed, for all I know) that this can be adjusted via the kernel. Does anybody know of anything that might help with this? It's so sensitive it's making me want to avoid the damned thing. I'm about ready to restore the stock ROM and give it to my sister as an early Christmas present.

The awesomeness that is Hashcode is working on 3.0 kernel over in the dev section. The kernel is still a work in progress and has come a long way. At the end he is apparantly going to update the touchscreen driver. I hope that will fix any said issues.

Perfecting the One - progress of fixes

Initial releases almost ALWAYS flesh out some build issues that quickly get fixed (even Apples, but not so often), so hopefully the title says it all. Since we already have seen a few issues with the initial builds, such as camera sensor quality, case gaps, dead pixels, etc., maybe this thread will be a good place to keep watch on the progress of the HTC One issues being remedied, as many of us wait for HTC to perfect the One before we make our order. We don't want to get stuck with hardware issues that may be quickly remedied after initial release.
So you early adopters can help the lurking masses who are anxiously waiting for the right time to buy. Once we have a lot of people reporting what is or isn't good, we can then get an idea of when issues are not really issues anymore.
Please list any hardware issues you have noticed (software too, but no so important since software can be fixed after purchase), and/or list any fixes to these issues or opinions on whether these have become non-issues, so that many of us who are waiting can check the problems off our lists. If there are ways of identifying which hardware versions have the problems vs. which ones do not, that would be great info for this thread as well so that we can check a device in the store or quickly return a device before committing to a purchase.
Hardware issues:
-- Camera sensor yielding image issues such as mis-focus and/or color banding in a small percentage of units, partly due to a HUGE number of image sensor being rejected and causing initial release delays.
-- Gaps is the seams of the case materials such that the unibody design doesn't seem so smooth and seamless.
-- Stuck display pixels or observable differences in displays on a small percentage of sold units, possibly due to HTC using more than a single screen manufacturer.
-- Is black anodize hard enough that resistance to scratching and chipping is on par with other brands out there?
-- Signal reception issues
Software/driver issues:
-- GPU tests not scoring as expected, in comparison to similar phones currently coming out.
-- Volume level adjustability more granular in the low volume end.
-- Capacitive buttons not responding when they should.
-- Battery Drain issues
-- Acceptable menu button solution / HTC logo touch digitizer mapped to become a button (not necessary, but would love to see developers make this happen!)

The sometimes-not responding capacitive buttons which are most likely a software issue.

Also:
-Fix the color temperature of the screen, it's too much on the cooler side
-Fix the audio hissing in some 1080p videos made in a quiet environment
-Sense drains too much battery in stand-by
-Improve 4G/LTE signal reception
-'msm_hsic_host' wake lock keeps the phone awake on stand-by and drains battery

If it is you touching it with your ear, then that is still a problem, as the proximity sensor should sense that the phone is close to your head and then shutdown the screen and touch sensor input so that touching the screen does nothing.

Maybe u could add links for each of the problems to related threads so users can get more info?

I just checked out the one at a nearby at&t store. I had such a hard time with the capacitve buttons that I am reconsidering the phone. Not once did I get them to work on my first touch. Extremely disappointed. Hoping it was that one model in that store. Will check out another store. Also looking at xperia zl as an alternative now. So disappointed though as it was pretty awesome looking and extremely light.

My biggest issue with the lack of menu button is that I've always used it to quickly pull up the address bar on my browser. If you gently scroll up or down on the browser it will pull it up, but it doesn't always work very well. That is what I would like to see a solution to, first and foremost.

The home and back buttons are not very sensitive and don't always react on my first attempt. Also the battery is draining extremely quick. I'm losing 12% per hour.

Care to share the light on this? A link or instructions?

I don't quite remember where I read it... I've been stalking these forums for a while because I really want the phone... If you play around in your settings, somewhere there's an option to adjust/calibrate the sensitivity. Then, if you just very lightly touch the buttons, it will calibrate to that sensitivity and then fixed!

So I went and checked it out at another store and there was no problem with sensitivity. It had a weird problem where home would just bring up whatever screen you are on. Must be particular to that phone. Either way the sensitivity of the buttons was totally fine which was the main issue.
Also liked at xperia zl which is a fine phone in its own right but it just does not compare to the one. Although it does have one advantage which is that it is much easier to hack and get aosp and also get klp when it comes out.

Solution to irresponsive back/home key

Case pitted
Got my 64bg on the 19th via mail direct order ATT. Top of aluminum case near power button front side chamfered edge had 2 pitted dents. Put back in box and immediately went to ATT store to return for new order replacement. I also noticed some rough finish in edges of aluminum casing where it meets plastic fill. Not at the level of my Iphone 5 fit and finish. Will see what replacement looks like in the next few days once received.

I'm glad I'm not the only one who feels the need to stab the hell out of the capacitive buttons when it comes time to go "home" or "back."
One of the few things that has agitated me about this phone is the effort required to press the back and home buttons. I actually began wondering if they were pressure-sensitive or something. After all, my Note 2 would often register inadvertent presses of the back and menu capacitive buttons because they were so sensitive. With the Nexus 4, the buttons are responsive, if not hypersensitive.

I have just set my calibration and the home /back buttons are immediately more sensitive.

Consensus is: yes, the hardware might support it, while software currently does not.
The sensor array likely completely covers a rectangular area but the coded area does not include the logo area. This might be hackable at the kernel layer.

Swipes register as taps

I recently got the Verizon lg g4 and applied a tempered glass screen protector right out of the box. A lot of the time when I am just browsing reddit or xda my swipes register as taps and result in unintended and undesired actions. This is becoming super annoying and is definitely spoiling my impressions of the phone. Does anybody else face similar behavior? How do you deal with it? Do you think the glass screen protector has something to do with it? Thanks

Same issue with no protector... Browsing 9gag is a chore when swipes becomes taps

Same without a screen protector. Doesn't happen often enough to be an issue, but it's certainly happening.

Same here.

We are all dealing with it. Sucks beyond belief. I even swapped my phone out ad still the same crap.

I had the issue on my first one returned it and bought a second and it's fine.

I disabled dual window on my G4 not sure if its a placebo or I just got use to using the phone because it does seem alot better now.

I had dual window disabled from the get go and I still have this nagging problem ?

I have had this too whilst swiping through nova drawer

I have a VZW G4, which is notorious with being late for updates. I wonder if those other carriers that forced updates may be the culprit here. I have no tap, touch, swipe, etc issues. And if that's not the issue, maybe the first batches that came out have defects.

I've had this since I got the phone more than a week ago, disabled Smart settings and dual screen but it still registers taps when I'm scrolling and is annoying. I've adapted my scrolling techniques and although it's not 100% perfect it's way better. After coming from a nexus 5 though, it's a disappointment. Hopefully an update will cure things as I think the screen is too sensitive

i've also been facing this issue "swipe register as tap" on notifciation, status bar, app drawer on stock launcher and Nova, with or without scratch guard.

I don't see how some people are not noticing this.. My past phones include N6, S6, G2, G3, S5, even as far back as the S4 I have never really experienced this kind of touch screen issue.. I guess the worst part is its very sporadic.. I can't reproduce it consistently but it is a problem. I have no issues trying to get a replacement device but not if its going to act the same.. I really hope LG admits there is an issue an addressees it in an update. I still have my G2 and I use the same swiping "technique" with no issues on that phone..

Can someone on tmobile or another Cartier who recently got an update chime in if the update fixed some of your Touchscreen issues?

For me, this happens if I swipe very softly. It seems like my G4 is just less sensitive to swipes compared to my old S3.
But I will admit, it is kind of annoying when I inadvertently swipe too softly and click on a link/ad/post/etc.

I have the latest update and it does it on my T-Mobile g4. With or without a protector. It didn't do it before the update though.

I'm on AT&T. I exchanged it yesterday because the issue was absolutely maddening. I tried every fix I saw in these and other forums. Nothing worked. So far I have had no issues with the replacement.

Strange S7 Edge screen sensitivity issue

The strange issue is when I'm not holding the phone (in it's cradle or sitting on my desk), the touch screen is almost dead. It takes 5-6 touches or a long press to register the touch. The strange part is when I hold the phone in my hand the sensitivity is normal (not all that sensitive but at least you can use it).
I do notice when it's out of my hands that if I touch the screen and hold anywhere with one finger and use another, It responds like normal. This makes it unbearable in the car.
I've tried the the pointer speed increase and the TSP firmware update also. But no luck.
I'm running the latest G935U rom PI3.
I've searched a lot and can't find anyone else with this same problem. Any help would be greatly appreciated.

Just tried it on my S7 Edge and touch works well.
There's a sensor called "grip sensor/detector" in our devices. It knows when You hold Your phone and when You don't. Maybe some app on Your phone is using it and somehow messes up Your screen?
If it gets too annoying then take it back to Samsung and show them the issue. They should fix it.

Thanks for your response. That makes sense. I can't seem to find anyway to turn it off or at least modify the settings.
The only apps are the ones that come with the "U" firmware.

This might sound stupid, and if it doesn't apply to you I apologise.
But are you using a screen protector? Maybe this is inhibiting the sensitivity?
Just an idea

I have the exact opposite problem. My screen is so sensitive that every time I pick up my phone an app on the edge of the screen opens. While holding the phone, if my palm just barely touch the screen, apps will open. I've had this phone since the first day it was released and had planned to buy a Note 7 because of my overly sensitive screen. I really like this phone, best I have ever owned but I'm really getting tired of this screen issue.

I think I remember trying that TSP thing a few months ago. I believe it doesn't work with the Verizon S7's. Changing pointer speed doesn't help. I do have a plastic film screen protector. It's hard to find a reliable glass protector which I prefer. Thanks for the suggestions anyway.

LG G2(D802) Touch issues

Hi guys i have just got the LG G2 from ebay and i have serious touch issues, sometimes when i swipe left or right it takes a few tries but scrolling up and down is fine, typing on the keyboard sometimes presses random leters or numbers, playing pokemon go is useless u can't do curve balls because the balls just drop because of the screen issue..
I have upgraded it to 5.0.1 and the issue still persists .
Is there any fix for this, i don't mind rooting and flashing etc, thanks in advance.

Can't say for sure, but could be your digitizer in your screen.
If it persisted through software change, most likely hardware based.
I just bought a new LCD/digitizer for my wife's G2 from Fixez.com for like $50. If you know someone or feel confident in your abilities, the swap isn't that hard. Videos on YouTube help.

Thanks for the help, i only just got it today secondhand and it was on 4.4.2 factory reset and its been doing it since i turned it on, i upgraded to 5.0.1 and it still persists, i noticed on the top left hand corner that the glass or whatever is slightly lifted and the selfie cam is not centered, could this be maybe a factor?.
A quick edit, on Pokemon Go when i move my finger around the screen see around me and behind me the game zooms in and out, so im thinking it might be the digitizer.

I have an update guys, this might be a bit more help, i have figured something out by normal touching the screen as you would do thats when the screen becomes useless but if slightly touch the screen like with just skin then the screens flick through normally and i can actually throw curveballs so the screen acts normally.
