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!

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

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?

[Q] in call bug, help needed

I have a really annoying bug in my WP7 HD2. When i make a call, the screen goes black and i cannot access anything. The call connects fine but the whole phone locks up. I can't access the dial pad for using automated services, nor can i hang up. Hardware buttons do not work either, but light up briefly if i push one. I think its something to do with the light sensor, sometimes if i cover it and uncover, the screen quickly comes on then goes off again. Any ideas? I am using the latest radio from the stock HTC WM 6.5 ROM, and the newer (51t?) radio for WP7. I have tried older versions of both, and a few different WP7 roms all with the same problems.
WP7 Mango (xboxmod/yuki)
UK HTC HD2
This problem also happens on android.

Uhh, sounds awful 'cause you experience also on different Android...
Do you experience this also on a Stock WM 6.5 Rom (of course with the original radio and without hpsl)? If not, you can be relaxed cause it's no hardware fault then. If it's also present on WM 6.5, then it's very likely to be an hardware error.

a little update on my problem. it appears that if i tilt the phone at a 30 degree angle downwards, while in a call, the light sensor functions normally. so at least navigating those phone menues can be done! i think this is a hardware problem, my HD2 did suffer a pretty nasty fall (which resulted in a new screen!) so maybe there was some other damage beside the screen.

there are two sensors together to the left of the earphone at the top of the screen, one is a light sensor, the other a proximity sensor. It seems to be the proximity sensor that is at fault. When you put your ear to phone it switches screen off so you dont push buttons.
I have read that the prox sensor can become misaligned when replacing screen. Did it occur after this? warranty?

as soon as i make a call the screen switches off. also the auto brightness doesnt seem to be very responsive. the issue had happened before but it was more of a driver issue than a hardware fault. i noticed it more after the repair, but it was not instant. maybe one of the sensors was lose and after a few months of use it is now misaligned? the phone is out of warrenty, and the 3 month warrenty on the repair is also up, and i have no insurance anymore i am holding out for a new phone. just started a new job so hopefully i can get something outright without being tied to a contract

Same problem
I'm having the same problem I think I noticed it when it was running windows 6.5 but I really noticed it after 7 upgrade. as soon as I make a call I cant access anything. THe bad thing about it is this phone is a replacement. I just got it. Maybe they sent me a badly refurbished one. Has anyone found a solution to this. If i'm smart I know this is not as simple as changing a setting sound like re flash, erasing, re installing, etc.

did you try tilting the phone downwards towards you? when i do this the menu appears and i can access everything. normally i put it on speaker then the screen stays lit then i cna use it as normal

Screen going off during call or when call is over on G2 VS980

Hello, I have a problem with my LG G2 VS980 by verizon.
There are two problems depending on preloaded rom
1 The display shuts down immediately when call to someone. (after the conversation has will not turn on)
or
2 When someone call to me, after a conversation I can not unlock the screen (either the knock on, or by power button - appears on the screen and immediately turns off).
I've tested all the roms that are available. The one who runs without problem with the display there is a rom by HeatshiverSX - 4.3.1. The problem is that this rom has problem with the rotation of the screen.
Are you able to tell what's going on? Could someone help / advise? Thanks!

Anyone ?

LG G2 proximity sensor causes screen and touch problems during conversations

Did you manage to solve it by now?
If not, it seems that @Bam9 manged to solve it by a firmware update as he reported here.
It seems that there are two similar issues in LG G2 which are both caused by the proximity sensor which causes screen and touch problems during conversations:
The screen stays on and the touch buttons in the dialer (speaker, add call, mute, etc...) aren't responsive.
(This issue was already reported by @athorax here)
The screen turn off and goes blank while in conversation.
(This issue was already reported by @madafis here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.

Question regarding Ghost Touch and other screen issue

So my LG G2 D802 is using a stock Lollipop (5.0.2) ROM from Singapore that I flashed recently, lately my phone sometimes get ghost touches and sometimes the screen stops functioning. So my question is, can it be a software problem rather than hardware? When the screen is unusable, I can swipe to unlock like normal but when unlocked whatever I press doesn't do anything. The vibrate on touch is there but no action.

I am having the same issue. Have you got the solution yet?
