Touchscreen Unresponsiveness? - HTC Radar

So I made the jump from Android (Nexus One) to the Radar and I really like it so far!
I do, however, have an issue with the phone that I am wondering if anyone else has noticed.
I have noticed that sometimes when I go to touch a tile(or other UI object)...if I quickly touch it, it seems that the screen doesn't always detect my touch. Sometimes I'll even hit it a couple of times before it responds.
The behavior is inconsistent though. After it smartens up and responds to my touch, then it seems to detect it fine. It's squirrelly and a little disconcerting.
I also think that the region of the screen might have something to do with it. The tile 2nd from the top on the home screen ("messaging" in my case) seems particularly susceptible to this problem.
Has anyone else noticed this? I'm a little paranoid because I bought this phone "new" from someone on CL and when I took it home I realized it was a refurbished model.

I had this problem when I had my 7 Pro. After a while it got worse, as I had to put the phone on standby and then turn it on again to be able to use the screen. I sent it in to HTC for repair, and they swapped the entire front panel with a new one.

Im having the same problem with my sprint arrive I think the problem is related to what is in this thread:

but I still cant seem to get it to work

[Q] Screen flicker/dims/blacks out issue

Any help much appreciated....I have an issue with my screen flickering, dimming very faint and going black when i touch my screen. sometimes my screen will go black for long periods of time and phone is practically useless. This is not an issue of just a slight flicker on light colored screens that I have read other people describe. The screen does not always do this but is definitely getting more frequent. The flickering/dimming happens when I touch screen and especially when I touch it with more pressure. It also seems to be more sensitive on the bottom half of the screen.
I consider myself as the "scientific type" and have been testing many different scenarios trying to find a rhyme or reason to this happening. The only thing I have found is that if I keep my phone out of my pocket the problem seem to not happen. Then I can put my phone in my pocket for as little as 5 minutes and my screen could be messed up for hours. Everything else about phone seems to work great.
At first I was thinking this was a software issue but now I am leaning towards hardware? I am rooted, unlocked with s-on and cannot send back for warranty. I was running mean Rom for many versions and have also gone back to stock rom and stock kernel and experience same problem. Many reboots and clean installs too. I have also taken phone apart and reconnected all ribbon cables hoping there was a bad connection.
My Evo lte is only 4 months old and has never been dropped nor has it ever been wet. There are no scratches on screen and has been in otter box since the phone was brand new. I am running out of ideas and am I dire need for advice.
Thanks,
Mike

[Q] My HTC One's touch is acting weird...

So, this thing drives me crazy...I've tried everything I knew and still nothing solved this problem.
I'm using HTC One. About 10 days ago weird things with touch started to happen. It seems that touch is partly unavailable/unresponsible on touch in one or two small areas. It seems to me like theres an empty place on my touch. Visualy is everything fine. Screen is crystal clear and has no damages or scratches. But I can't slide icons without troubles. Somwhere on 1/4 of screen, touch brakes briefly and I need another try to slide the icon. The same thing happens with status bar on the top of screen - I can slide it until that 1/4 part and it stops there and goes back. If I slide it quick with short move, it works fine, just slide alone over problematic area.
Also, few times I had that problem where screen works things on itself will. Makes pictures, or adds filters on Instagram, or, I don't know, just jumps around for few secons. Then, I lock the screen, then unlock it and usually that calm down the screen.
Also weird thing is that, when I want to send message, I can't reach "send" button in first try. I have to drop down writing sheet, than to touch the letters to put it in writing mode again, and then I can click the "send" button. On the same place where it was previously!
At first, I thought that plastic case or PVC protection is the problem, so I took off the protector from the screen. That solved problem for a bit. Then, I put back screen guard, and problem came back. After I totally rejected screen guard, problem is still here. I've tried to reset phone on factory, but that wasn't helpfull...
I forgot to state that I'm using Android 4.2.2 and this started to happen after that version update. I had no problem before.
So, now I'm here, as I don't know what else to do before I take this beauty to service. I just hope that this happens because of software bugs :crying:
Is there anyone who could help me? Have similar problem or know how to fix this?
In the meantime, I'll just hope that 4.3 will fix it themself... :fingers-crossed:

[Q] [Xperia U] My touchscreen seems broken / acts very strange

I have got a (most likely) hardware related issue with the touchscreen of my Xperia U.
Some parts of the screen are not or barely responsive, which is very annoying when typing. I have to tap some letters twice before they actually work. (It's especially around the 'i', 'n' and 'e' when I have my keyboard open by the way.)
I was running stock Android GB and I'm now running stock Android ICS, after I updated my phone the problem was still there which is why I assume it's hardware related. There does seem to be a slight improvement though, but that's probably because ICS feels a bit faster (so far).
Like five minutes ago I noticed something very strange, when I put my finger near the 'N' on the keyboard, but not touching the screen itself, it kept touching it like 10 times a second, sometimes holding the touch so it would result in a ';', but that's not really relevant I guess. It stopped doing that after I turned the screen off and on again by the way.
Now I've downloaded a drawing app on my phone, to see if the phone would skip the parts that were responding bad, but that wasn't the case.
(I would send a picture, but I'm not allowed to send outside links as I'm a new user, sorry. )
There is a chance that this problem is caused by a kind of overpowered charger I had been using last summer, because when I plugged that in, the phone started doing the same, only waay worse. I haven't used it for almost 3 months though, and the problem occurred just a few days ago, which is pretty weird.
I can probably get a replacement touch screen for free because my brother had this phone too and he bought a new phone because the glass of his screen broke.
But I hope I don't have to use that, haha :angel:
Is there any solution to this without taking it to a service center or replacing it?
Thanks!

Lots of touchsscreen thread in the forum, search and see what they did

[Q] Touch issues even though i have the latest FW?

Hi, i have had my tablet for about 1 week, straight after starting it up i had a fw update which is 17.1.1.A.0.402 which i am assuming is the latest?
anyway i have read a lot about the new fw was supposed to fix the touch issues?
I also have the z1 which i still have and is perfect. ive recently updated to 4.4.2 on that and all my issues are fine on there.
my z2 is acting very strange, if i leave it alone for a while sometimes i will go on it and everything on the screen will be frozen, i can't tap anything, i have to press the power button and then swipe to open it again, it is then fine after that.
also i have noticed, and i think its happening a lot when my tablet is a little angled using the case, the screen will be a bit jittery, where as my z1 is really smooth, and i also sometimes have to really tap icons a few times before they register.
i play clash of clans a lot and its been a bit difficult to play as troops aren't selecting as i am tapping on them.
has anyone got any advice?
I have done a factory reset to see if that would fix any issues from the fw update but its still exactly the same.
Thanks
James
anyone?

I installed the new firmware yesterday. While I notice an improvement with the touch problem it's still present. Just install an multitouch app (like this one: https://play.google.com/store/apps/details?id=com.easylabs.multitouch), let your finger trail on the screen and it's definitely obvious (the number on the top right should be the number of fingers touching the screen and it's often not). I tried the same thing on my old Iconia A500 and that's the one thing where it's WAY better than the Z2.
I don't experience anything as strange as you do though, it's mostly usable and I hardly notice it with the new firmware.
I did experience something very strange just BEFORE updating with one specific charger and one specific USB cable , the tablet wouldn't register any touch at all while it's was plugged in. As soon as I unplugged it it would work. The cable was fine with another charger and vice versa;
Weirdest of it all:
This happened while I was testing the output current for each combination of cable/charger and this particular couple was the one giving the "best" results; consistently between 1.1A and 1.2A
I can't reproduce this behaviour with the new firmware. All in all, it's usable for me. Biggest bug would be it not charging while playing power consuming games.
I have found mine goes more weird when it goes to sleep and i then wake it up, the screens sensitivity seems to be terrible, i have topress the off button and then start it again then its fine.
it will then mostly stay fine until the screen times out again then the same thing will happen when i wake it.
James: Same with my 521...
Touchscreen response was REAL BAD after updating to .402, then it went better and better day by day; strange phenomenon.
I also occasionally experience some touchscreen "numbness" after waking up the table with a double-tap, sometimes touch sensitivity suddenly becomes quite low just without any reason; touchscreen has problems detecting touches near the screen corners or doesn't react to touches at all. Solution: Switch to standby, and back on.
At the same time, the Android symbols (Back, Home, last apps) again become difficult to hit.
You can test this by slowly swiping your finger up from the lower bezel towards one of the symbols: If the touchscreen is ok, symbols get highlighted right after your finger reaches the lower edge of the symbol. If the touchscreen malfunctions, you need to move your finger up to the center of the symbols to get them highlighted.
So it smells like a software issue.
Touchscreen problems usually occur two to three times a day of normal use; so I regard it as acceptable - but the problem still isn't fully solved.
I would say it's a hardware issue which Sony attempts to counterbalance with software patches.
Just like on the Nexus7 (2013). There sfhub released a touchscreen fix which made the problem bearable for most users (with some experimenting with different versions of the fix, because each device is different).
I wrote a PM to sfhub asking him whether he could disclose how his fix works so that Z2 Tablet users perhaps could apply a similar, variable, tailor-made fix to their individual device.
No response, unfortunately.
Perhaps some of you could send the same request to him, and perhaps then he reacts?
every now and then, after double tap to wake, the tablet is extremely unresponsive.
I also just sleep/wake up again via power button and it's fine after that.
So my but feeling it's a software issue, not hardware issue.

I never had touch problems but after updating to the latest firmware, the tablet is unusable from time to time
what's annoying me is that Sony wont seem to admit that there is an issue, i was talking on their live chat to support and they said that's the first time anyone's mentioned that and isn't on any list of any known issues
Which doesn't fill me with confidence on how quick this may get fixed.
The speed in which is gets fixed may determine if i just send the tablet back to Amazon for a full refund, unfortunately i have bought the Sony case and magnetic charger now as well
I'm just really puzzled what to do, what can i do apart from sent it back if Sony wont even acknowledge they are aware of the problem and will release a fix soon
The only thing is because i have now bought the charger and case, i kinda want to keep it.
It was a direct replacement for my Z1 which i still have, and that is also updated to 4.4.2 now, but that shows no touch issues at all.
What's very interesting and revealing:
When Sony was addressed a few days ago regarding battery problems on Tablet Z and a few phones after the Kitkat update, they immediately reacted!
They readily explained that it is a problem with the Google Play Services running amok and that a fix will come.
But it seems that just because this here is a Sony problem (and not one for which another company can be blamed like in the above one), Sony simply doesn't react at all and obviously orders the service employees to lie and say that they haven't heard at all of a touch problem.
Boooo, Sony, shame on you!

HAHA ! Exactly the same in Germany. Even after talking about that issue with the SAME person three days in a row, I still was told the problem was totally unknown.
Later, I had a more private talk with one of the support guys. He revealed to me there was an order from Sony to tell callers exactly that.
Ah, as I thought.
This is abysmal behavior by Sony, period.
Also on the Sony support forum, none of the official support staff has replied to any of the topics about touch screen issues. It seems they are just completely burying their heads in the sand...
FW .402 didnt fix the touch screen issue. It is noticeably better than any FW from before.
Gosh, the touchscreen keep going back to home when i'm in a middle of fb conversatuion.
I was testing with chromecast +youtube: those swibe action to enlarge or fade out afe 99% imprecise...
Really wondering if I can return the item to amazon to fix this problem...

Are you sure you're not just accidentally touching the home button while typing? That happens to me from time to time, which is a downside of having the navigation buttons centered compared to having them in the corner like on pre-4.4 Android tablets. I actually think Google should add a setting to choose if the navigation buttons on tablets are in the left corner, centered, or in the right corner. Having them centered also makes it awkward to reach these buttons when holding the tablet with two hands.

Problem with touch screen or software bug?

I bought a Mate 20 Pro on preorder and noticed within a few days a seemingly non-responsive part of the screen that was an intermittent issue.
Basically every now and again (often enough it’s annoying but not every time) after I unlock the display I am unable to select any app icons in the lower half of the touchscreen. The top half is fine - the home buttons are fine but everywhere from the middle down is non responsive.
I assumed a hardware fault so amazon replaced it for me - and the new device is exactly the same!
Am I just super unlucky and have managed to get two faulty devices a month apart from Amazon or is something else causing the issue?
Thanks.
Think you've just been unlucky,nothing like that on mine
Fine here too. I assume you tested this as soon as you got the phone before installing any app / custom launcher?
Have you tried running smart diagnostic tests manual mode in hicare, there's a touchscreen display test.
Sent from my HUAWEI LYA-L09 using XDA Labs
I only noticed it in use after I used a custom launcher however I tried multiple launchers and saw the same behaviour.
I just did the HiCare test and it says normal. I did hard reset it the other day and it hasn’t happened since so I will see if anything else happens. I can’t say I am thrilled by the thought of another swap from amazon if it does happen. That’s super bad luck.
Hi how did it go after the hard reset?
I got the same issue myself but instead of being the lower half, my entire screen does not respond to touch. I've done a hard reset my self and i do run the stock launcher. Even though my screen still doesn't respond to touch now and then after unlocking the screen or receiving a phone call.
Touchscreen issue
Yup I get it annoyingly so as well! Often takes a "double tap". Pain in the ace!
