Touchscreen functions without touching it directly - Sprint HTC EVO 4G LTE

My evo 4g lte has been wonderful with MeanROM. I have noticed one peculiar thing with the capacitive touch screen. When I brush my finger slightly above the panel and not touching it, functions activate. Or sometimes when I'm entering data I'll make a motion toward the screen but not touch it and it triggers. This is disconcerting because I'm afraid that I'll dial out inadvertently or save any entry when I'm not intending to. Have any of you noticed this same behavior? Is there something wrong with my touch screen? Also, this behavior exhibited itself even when the ROM was stock.
I tried doing the recalibration on the keyboard but that didn't help.
Thanks,
Jon

its normal. happens on mine and my original evo. these screens are crazy sensitive. just gotta get used to it

You obviously have some psychic powers!!

It's because the screen and most touchscreen these days are capacitive. They rely on electrical impulses that the body naturally gives out therefore you can be close to the screen and without touching it, it'll register the touch

Unresponsive touchscreen

I don't know if you guys have noticed but I am on my second atrix already and both have suffered from unresponsive touchscreens. I find myself having to tap things multiple times before it actually registers. I never had to deal with that on the Evo. Is there any settings I have to change to increase sensitivity or screen calibration. Tell me I'm not the only one noticing this.

Does it happen when you charge the phone? The area around the capacitative buttons is very sensity to touch. If you by accident touch that area with your palm the screen doesn't respond.
I've noticed the opposite, sometimes when typing I hit buttons just by being close/hovering just above them.
I did have a problem with my screen going nuts after I deodexed but I just odexed and redeodexed and it fixed it.

[Q] 3VO Durability

Hello
I'm wondering just how durable an E3D is, namely the touch sensors inside it.
Recently I dropped the phone twice on a hard surface, and started noticing strange behaviours, firstly with the touch functions and secondly with the phone always freezing up.
Not always, but sometimes when typeing, it's just a mess, the capitalizer writes a letter, multi letter feature is inaccessible, basically none of the characters work like they were ment to. The only solution thus far is to lock and unlock the phone, which fixes the keyboard and the touch functionality.
Sometimes I can't unlock the phone because the ring moves 3 times shorter of a distance, opposed to when its working properly, and if so you can forget about dragging icons into the circle to answer a call, it just won't go in all the way.
Oh and the freezes, completely, none of the touch sensitive buttons or the screen responds, sometimes the screen is the only responsive part while the buttons are completely dead, a lock/unlock is needed to fix it short term, also the buttons led go out, becoming none responsive, sometimes the led is off, yet I still get a vibrational feedback (Have it enabled) So all these irregularities are new, it never happened before dropping the phone! The only touch sensitive related issue I had before, from time to time, was the unlock pattern gesture not tracing, instead of sticking to the first circle I begin at, it moves to the next I drag my finger over. (also fixable by relock/unlocking)
During this post the keyboard wasn't acting up thankfully, but its getting more and more irritating to lock and unlock the phone while typing a message to someone.
First I was suspecting a virus, or low memory causing this behaviour, but after thoroughly cleaning the phone and acquiring more memory (by closing apps) I was still having the problem.
Any idea how sensitive the components are if subject to repeated shock from a distance of 1.5m or 5ft?
What are my options here if the irregularities persist?

Don't know how durable it is...but I too face the unlock pattern issue sometimes, IMO it is a software issue .. Also if you take too much time to draw the pattern the screen goes off (even if you keep your fingers touched)......

If a reboot fixes the problem, then it's not hardware, its a software problem. Do a factory reset.

Dropping your phone will usually cause hardware problems. Get a case or don't drop the phone anymore.

DON'T use task killers or force close apps, that only makes things worse, and is probably what is causing your problem.

Well when app's foreclose there isn't much to do but close them ?
The task killer, well, I don't really use it much, I just have it, its called eRay..

Here's an update on this issue...
I've noticed that the upper left corner is the cause. How?
Well, in landscape mode on my homescreen, trying to pull the notification bar down (then from, the bottom left since were in landscape) will instead (without any animation) try to go to full homescreen view where I see all my 7 homescreen, but it does it in a zoom like feature, where the more I pull it to the side the more it will zoom in until final animation frame is reached LMAO.. I'm actually crying...
The sensor might be off, in that corner of the screen as dropped phone tend to land/hit the corners first...
I should ask an xda dev. to cook me up a "sensor status check" app to check if any of them are functioning incorrectly..
I don't know what more then that I could do?!..

Hey guys, thought I drop my final verdict on this issue.
As you all (who read this thread) knows, I was having an irritating problem with my E3D, namely the touch functionality of the screen was messed up, but only in a certain area, where I thought the sensors got discalibrated from the drops the Phone went through on hard surfaces.. I have used an app called "Check My Android" and the feature "MultiTouch" to identify the spot on the screen, where if I touched, a daemon took over my phone and started all kinds of wired behaviour such as item triggers on the other side of the screen and freezing, even slow mo zooming of the homescreen, one touch passive zooming of webpages and so forth..
Now with that app, I was certain that everything with it is not in order, but I didn't have the slightest clue on what to do about it. I ran across a comment about the built in utility diagnostics tool code for the Phone while browsing on U2B (YouTube), so by typing "*#*#3424#*#*" (which starts as you enter the lasts star) will basically allow you to test every aspect of functionality of your phone, where i also went for the screen draw test, and found myself strengthening what I already thought was the problem "an area on the screen messing everything else up" as I pressed within this area I found a straight line jump, from the "dead zone" to the bottom middle of the screen, as I was drawing circles, it drew a straight line there as i went over it with my finger every time. Than browsing on after that code's discovery, for "EVO 3D touchscreen problems" I ended up on a video offering similar problems..
Now the breakthrough or rather yet the solution came from that videos second and only comments, saying how "Disabling the ScreenLock of the Phone would fix that problem" and so it did!!! I'm not having any disturbance while typing, flipping pages touching that area or anything out of the ordinary, otherwise the Phone was almost unusable. It let's me to believe its a software miscoading flaw, but it wasn't always like that even though I used the screenlock since day one, so I'm not entirely sure what's up? other than its fixed...
I hope this fix can relieve others just as it did me
And the diagnostics code is also useful.. should be stickyd :]

Never mind that, it was only a temporary fix, as it started doing it again after a while...
Try calibrating your screen via display settings if you haven't already. Also are you having just touch screen issues or are reboots part of the issue as well ??

It's screen issues only, no reboot problems yet..
I have calibrated the G-Sensor several times...
In another post someone replied, that its a grounding issue, and trying that once it did give a result, but then again, I'm not having that, unusable level of the issue I was having, after a hard reset.. so I'm not really sure weather this is a grounding problem, an app caused problem, all I know is that I still get an extra touch input on the screen, when I approach the upper left corner.. with every multi touch app I test..
Have you tried that app called touch screen booster ??? If not give it a shot. Set the multi touch point settings to two. Then apply then start the service and select run at boot. Then reboot and see if it helps any. Also a way of trouble shooting to find out if it is a rogue app is to Uninstall all of your apps. Then see if you still have the issue.

Yes i have, thanks to you, but it was futile. Had no impact what so ever...
It's handed in for repairs, so I'll know what it was soon..

No i have not rooted, i was waiting for the official ICS before i root.
So I'm on the Stock... everything lol
This is my second 3D. The first one stopped responding to touches. Sprint replaced it for $30 even though I bought it from wirefly.
In my own experience, I had the exact same symptoms. Only difference is I didn't even drop my phone. After a few months of owning the phone it started to show the aforementioned symptoms occasionally. Eventually, it just got worse. After a lot of forum searching, google searching, etc, it turned out to be the digitizer that was faulty. I had tried everything from flashing different ROMs, Kernels etc before I was finally able to narrow it down to a hardware issue. The digitizer seems to be an issue for a lot of 3VOs from what I understand.
Luckily I had a friend who replaced the entire front housing of my phone so I wouldn't have to exchange it since I was unlocked on HBOOT 1.40. At the time I was afraid that, had I gotten it replaced, I'd have to deal with Hboot 1.50 and HTC's half ass unlock method. Either way, after that it was like a brand new phone but better cuz I didn't have to redownload apps, etc since the motherboard and software weren't touched at all.
Hope it all works out for ya... G'luck, brothah!

Shame I hadn't seen this thread sooner, I could have saved you a lot of time. I am on my 3rd 3d. Basically any fall which lands on the touchscreen will cause this problem.
What makes it worse, I was rooted with my last phone, and when it happened, I had to unroot before I could take it in for repairs. The touchscreen was so badly damaged with this problem, I could hardly do anything.
TL;DR get a case that will cover the screen and protect it from flat on touchscreen falls.

Portions of touch screen unresponsive

Hey guys,
My fascinate has this issue of parts of the screen usually the middle not being responsive to touch. For example if I was doing the pattern lock, when I go to the middle, it would say that I did the pattern wrong like if I took off my finger mid way doing the pattern. If I was say browsing the settings, it wouldn't respond to my swipes in the middle to scroll. Or my favorite when texting. The keys in the middle of the keyboard would not respond to my touch only the sides. If I press enough times, it will register my press. The only thing that would fix this unresponsiveness is to turn the screen on and off. From what I've seen this doesn't happen with the stock roms just with anything else that I flash. I've been flashing since the early gingerbread leaks and with every single rom, I had this problem. Do you guys think its a digitizer problem? I am using currently AOKP milestone 5 glitched.

Calibration issues

Hi,
I just got an EVO 3D today as a replacement for my old phone that broke. I noticed that the touch screen records some of my touch inputs a bit to the left. So when I touch backspace, it actually types 'm' and when I try to touch p it registers as o. I don't want to go to the trouble of going back to the sprint store, so would calibration.ini work still on ics?
Yeah, you should be able to go into settings under display and recaliberate your screen
Mine does the EXACT same thing. I rarely can type a p to save my life (although it is more tolerable using Swype). It seems like the right 5% of my screen is unresponsive.
I couldn't find any calibration under Display in settings (I'm running a sense 3.6 custom Rom). Where exactly is it?
I'm afraid my digitizer is messed up, but I don't get the craziness of ghost presses and such. But this issue happens for me on every Rom so I'm leaning toward a hardware issue.
Any help would be appreciated. :thumbup:

ICS and JB touch screen issues?

I thought it was only me upgrading P920 from GB to ICS and JB and got touch problems, but a quick google with "ics touch screen issues" reveals a lot. This problem seems well-spread across devices, ROMs, kernels,...
Basically the main problem is that it's harder to get the phone to register/recognize a touch/swipe. I sometimes have to touch/swipe multiple times for the action to happen. Sensitivity doesn't seem like a problem here, because a very light/soft touch can still be recognized. It's just that the screen often doesn't recognize the touch. Turning on pointer location in development options is the best proof. Try tapping the same spot on the screen lightly (as normal use) and some times it will register the touch, sometimes not. At first it seems like no problem but gradually becomes very itchy for everyday use. It's like using a defective product. But it is definitely NOT a hardware issue, because every time I revert back to good old GB (any version, any kernel) the touch screen just comes back alive. Every slightest touch and swipe registers beautifully, never misses.
So if your device does not suffer from this problem, lucky you. Us who are suffering from this, would like to have some cues on how to solve it.
NOTE: SGS touchscreen booster DOES NOT solve this issue. It's a great tool, though, to increase the touch sensitivity. But as this is not about sensitivity, it's useless for me.
So anyone have a solution? Thanks in advance!!!
