Touchscreen not responsive unless left softkey is constantly pressed

Hey guys!
I've seen people complain about broken Wizard LCD/touchscreen around here but none of them said anything about partially functioning touchscreen. So here it goes:
A few days ago my phone stopped responding to taps. Just like that! I updated the phone with the latest ROM from HTC (official) and no change. Since then I've been lurking this forum trying to find something similar ...
I've flashed it with custom roms, now I'm trying the WM6 with the hope that maybe the touchscreen will respond to taps by itself, without me having to keep the left softkey pressed while tapping. I can't decide if this is a hardware or a software issue.
If anyone should have any idea about this, please advise. I'm not afraid to open it up or anything like that...
ps: waiting on a replacement touchscreen I ordered off of eBay. ($12)
Thanks a bunch,
kevin

Same Problem
My touchscreen has been acting up lately and today it just stopped working. Tried many things like you with no luck. However I followed your advice on pressing the left soft key and the touch screen started working.
Does anyone have any clues?

touch screen prob.
if your touch screen is not responding then you have to chang the touch screen if it responce some where in time then you open you device and just resolder the touch screen film connector (back side of screen)its just get drysoldered thats why these things happen like you press rite side of screen and it geting work again if relese its stop working................
you have to do only re sloder the connector of touchscreen

Different Problem
Like the post originator said, the screen does work, you just have to hold the left soft key down while tapping. Also did take it apart and didn't see any problems.

Mine just developed this issue, anyone have a fix? I've got a digitizer (Touch panel) on order from ebay as a 1st step. Anyone have any other ideas?
Thanks!

Ok this is odd, but I'm suddenly having the same issue. Touchscreen doesn't work unless I'm holding the left soft key as well... This has to be software right? Anyone have any ideas yet?

I dont have this problem.. but this is 'interesting' I'm wondering, if it is hardware or software problem. For hardware problem, you can try pressing on the area around the left softkey rather than the left softkey. For hardware, you can check to see if it is working after a hardreset?

This issue has to be related to corrupted software that was installed, I mean how can this many people have the same exact problem around the same time if it's hardware related. Compare notes: All those having this issue,submit the most recent software that was installed, and if everyone installed the same thing, then that's the culprit!

Keyboard light never, ever, works.

Got my Sprint Mogul a couple of days ago and having a tough time with the keyboard backlight not working.
I've done my searching and found that some people got their keyboard backlight to work by unchecking the option in Settings->Buttons->Backlight.
This didn't work for me.
Some people recommended just hitting a few keys and the backlight should work.
This didn't work for me either.
I'm looking at what just may be bad hardware and will have to replace the phone. That keyboard is damn hard to see in even the best low-light conditions. Forget about typing in the dark.
Does anyone know of methods that will force the keyboard to turn on so that I can test it?

unchecking the auto sensor option like you did should force it to come on whenever the keyboard is out, if it doesnt come on within a few seconds of sliding out id say get a replacement phone

I agree with defaultdotxbe...if unchecking the autosensor box isn't forcing it to be always on, I'd be worried.
I've left the autosensor activated, and my keyboard light works, but I must admit that it sometimes doesn't go on when I think it should. The sensor seems to be calibrated so that it has got to be pretty dark for the silly thing to decide to light up!
Having said that, someone on one of these forums came up with a pretty neat trick. If know I want to force the keyboard to be lit, I just slide it out about a quarter of an inch. The sensor is still hidden under the body of the phone at this point, and it thinks it's completely in the dark. The keyboard always lights up at that point. Once it's lit, then I slide the keyboard out the rest of the way. Brilliant, huh? You might wanna try that just to see if it makes any difference.
Good luck!

Thanks, peeps. I had the same problem with the keyboard light and was getting extremely frustrated. I tried the sensor trick (opening the keyboard 1/4) and, viola, it worked!

I also had the problem and after lots of searching I found out it was because I had the screen backlight turned all the way down. I moved it up to the first notch and now it works just fine even with the sensor.

This trick also fixes the orientation issues when turning on and it is in landscape rather than portrait.

Touchscreen unresponsive in Landscape mode

Ok so i bought a brand new Nexus S two days ago, the problem is in landscape mode the touchsreen randomly becomes unresponsive for a few seconds or until i change position or turn screen off and then on again or rotate the phone and back.
The wierd thing is it only happens in landscape mode when holding it so the buttons are to the right but if i flip the phone so that its still in landscape but the buttons are to the left it doesn't happen and works flawlessly.
I searched the net and found various touchscreen problems with nexus s, but didnt really find the exact problem. Can anyone tell if its a software issue or a hardware issue?
Also this Nexus S is with Super LCD and not AMOLED
Thanks
NeM

I had a similar problem. Happened to me a few times on different custom roms. However, my screen is Super AMOLED. I'm just scared it might be a hardware issue so I'm always ready to unroot my phone and get it back to stock so I can return it for repair.
Butt.... I think that it might be a sofware issue since the touchscreen is only unresponsive until you lock and unlock your device. I'm keeping my fingers crossed that it doesn't happen again for a while. Always gives me a scare :O

Is it running a custom ROM?

[HELP] Unresponsive band of screen on D800 stock Lollipop.

Hi guys, I have experienced a number of screen relates issues on my D800 since the Lollipop upgrade. I am pure stock, took the upgrade OTA from ATT.
1. Knock on stopped working. Knock off works OK. I tried all of the suggestions online, update touch firmware, etc. but still no help. This is no big deal since I can use the back button to wake up the phone.
2. I noticed scrolling was unresponsive in Chrome but ignored it because I thought it might be me.
3. I was out and on the phone and I noticed I could not hear her well all of a sudden and then the call got disconnected. I tried to put my PIN in to unlock the phone but that area of the screen was totally unresponsive to touch. I could enter the numbers in the second row of the grid but there is a 1 in my pin and that would not register. I restarted a bunch of times which I had to do only with buttons because I could not click 'OK' on the screen to confirm the restart. I got a screen on the phone saying my screen was unresponsive and this is how to answer calls only with the buttons etc.
I got home and used by OTG mouse connection to enter my pin and navigate the phone. I did a factory reset which I had never done before. The responsiveness seems better now. There seems to be one section of the screen that is unresponsive, right near the middle. I can't click on any of the icons in the second row from the bottom. I can get to the notification shade which I don't think I could do before.
I am attaching an image of a memo where I just ran my finger up and down the screen without lifting it. You can see the dead area.
Has anyone had this problem or knows of any solution? Thanks very much.

I just RMA'd it. It probably is the same problem you had but I am pretty sure I am still under warranty so I just sent it in.

Touch Screen Unresponsive

I don't expect there's much that can be done if the hardware is to blame. This reminds me of my Galaxy S3 -- so it's a problem that everyone else fixed ages ago. When I touch the touchscreen, very very often, it doesn't register that touch at all. Sometimes you get a delayed response. This leads to all kinds of fun where you tap the screen again at the same moment that PH-1 responds to your first touch, so it applies your second tap to whatever is going to come up on the screen a half second later.
Does anyone know if this can be fixed by firmware updates or is this a hardware issue?

same here! my huawei honor 8 is much faster

Touch Screen unresponsive is a hardware issue. I had the same problem with my HTC U11 until it was replaced. Essential phone does not have this issue assuming screen is working properly.
Sent from my Pixel XL using XDA-Developers Legacy app

Touchscreen responsiveness, having to tap more than once for the screen to register a touch and awful light bleed caused me to send it back. But it was from the first batch that were manufactured. No issues on my U11, but I bought it in early August.

Confirming u installed the most recent OTA (NMI64C)? Because that fixed my touch issues.

Yep that's what I currently have. I think the phone found that update on its own a few days ago. Touch issues seem to be hit or miss and maybe less frequent since that update. We'll see how it goes from here.

touch unresposive is due too thermal trottling or like me the launcher stock.
Solved with Evie launcher

Using a different launcher and such didn't help me out, unfortunately. Besides the tap issues, scrolling through a web page in any browser or with apps was extremely slow and laggy. My PH-1 was already being returned, so I couldn't test the latest software update they pushed out. But my device also had some horrible light bleed all along the left and right edges.

No light bleed here. But [email protected], the responsiveness of this touch screen is worse than any other phone I've had. And the new software update hasn't helped at all!...

Same issue!
I too am having touch screen issues. Today, I was on the phone and went to go back to the screen and the screen stays black. I tried everything including pressing the power button and I got no response from the phone whatsoever. The only thing that finally worked was to press the power button and the volume down button and hold them at the same time to shut my phone off after the call already ended. In addition to that issue , I also use Swipe to type and when I do so it often skips over letters and types words that I am not even trying to type . It should be mentioned that I'm a very experienced swipe user and I have not had this problem with my S7 Edge or my Wellington . Also, I should mention that I have the most recent OTA. Also, has anyone else noticed that the camera shutter has a serious delay in it even with the Google camera mod?

I've noticed my touch screen freaking out sometimes. It has more to do with the screen having too many prints on it. Guess it's a bit too sensitive. I wipe the phone screen off and it's fine. Doesn't happen very often. I have one of the latest batches, pure white.

Already looked into this?
Sensitivity:
1. Tap on the "Settings" icon on the home screen.
2. Tap "Language and Input".
3. Scroll to the very bottom of these settings and tap "Pointer Speed".
4. Increase the slider to make the touch screen more sensitive and easier to tap. Decrease the slider to make your touch screen less sensitive and more difficult to tap.
5. Tap "OK" and then experiment with the results.
Essential Support still working on that and they send me this instructions for now.
I think it makes the user experience better.

Same.
Hope it will have a fix soon.

Early on I got the black screen that required a power hold reboot, since moving to Oreo I've not seen that

This I have experienced too

edit : solved with oreo beta

basongwe said:
When I touch some letters on my keyboard, it's unresponsive. Same with some apps. I don't know why this phone is so frustrating to use even if it's a very good smartphone.
EDIT : I'm on Nougat's lastest version, not on Oreo beta.

Had it on both versions to be honest, but hoping it's getting resolved as time goes on!

Just got mine..same thing but...
My screen was doing fine until i installed "All in one gestures". I was messing around with side gestures and this caused the screen to be non-responsive. I un-installed the app, reinstalled it and set it up differently and now it is fine.
I hope this helps.

This helped me. I have mine set at approximately 3/4 and I'm happy one day in. Seems to work great now. I would still like smoother scrolling though. Thanks a million.
I was also having trouble with Android Pay and then found a post about the NFC being located near the bottom of the phone as opposed to the top as on my Nexus 6p.
With these problems fixed I'm completely pleased with this phone.

ugh! Flashed back to stock on 7.1.1/NMJ32F/436 as that is how my phone came, and now I have no touchscreen after re-boot?!?!?! any advice? Please?
Thanks,
DJ
