[HTC U11  Questions & Answers] Doughnut:
Would you mind doing the screen test in HTC help and see if your screen behaves the same when touching two points in succession?

---------- Post added at 10:03 PM ---------- Previous post was at 09:57 PM ----------

Guys, I'm wrong - my brother's One Plus 3 behaves the same in a screen test app. Touches in succession leads to a straight line being drawn. So this is not the issue.
[HTC U11  Questions & Answers] EtherealRemnant:
I've got it.

FA=Taiwan

7=2017

6=June

1=1st

Not just the lines... the keyboard closing, SwiftKey deleting words and replacing them (which is exactly what the gestures do when a line is made)... Its incredibly aggravating and has considerably slowed my typing speed to compensate for the mistakes.
[HTC U11  Questions & Answers] Doughnut:
FA

7

6

8

Taiwan, 8th June 2017
[HTC U11  Questions & Answers] scotia_rfc:
I can replicate this on my device, but i'm not 100% sure that is the issue. I can get it to draw the line between the 2 points about 95% of the time. I think it might be a line drawing test issue rather than evidence of the issue we are all having. Who knows? I may be wrong!

My device details are :

FA : Taiwan

7 : 2017

5 : May

T : 26

P.S.

I am using Function Test v71.90.05g to do the line draw test
[HTC U11  Questions & Answers] Doughnut:
I made another post saying I was wrong. My brothers One Plus 3 behaves the same. I think that's intended behaviour, doing this may he more fruitful:

[HTC U11  Questions & Answers] scotia_rfc:
My apologies. I seen that after I had posted. I suppose I should have read the full thread first before posting.

So you are sending it for repair still on Friday? I'm tempted to send my unit for repair too, but the 10 day or so wait is putting me off.
[HTC U11  Questions & Answers] EtherealRemnant:
I wouldn't send it in for repair. Its likely fixable with a firmware update and if HTC says they can't reproduce the issue, you're out of a phone for 2 weeks.
[HTC U11  Questions & Answers] Doughnut:
He, don't be silly, no need to apologise or read a whole thread. So I've cleared my cache and I'm using the HTC keyboard and since I've not really had a crazy issue like the whole darting across the screen.

I'm suspecting that sales in the UK haven't been awesome with this device, so I'm going to wait a little longer see how the phone behaves and if it's still playing up I'll just go for a repair down the line. I have the box for my first device and manufacturing date is the same so I don't want a third device with the same potential problem.
[HTC U11  Questions & Answers] djbutter:
I would say that my touch screen experience is slightly different.

I've attached two screenshots of me using the drawing line test. In both tests, I never lifted my finger off the screen while drawing, but you can clearly see the line breaks.

It doesn't happen all the time though.
[HTC U11  Questions & Answers] WRXinNoCo:
[MENTION=3528351]djbutter[/MENTION]

Yep had that as well, there would be dead spots...and it would be random, one time there would be a dead spot in an area the next time not. Also the dead spot would be in different locations. Of course there were also time that the screen was just fine, and everything drew as expected. It is very strange how it moves around and randomly happens. What is the build date of your phone?

I will be sending my in on Monday, and maybe by mid September it will be back.
[HTC U11  Questions & Answers] WRXinNoCo:
Well guys I have some good news and bad news ...

the good news is that my son wanted a U11 so we order him one and he got it last week, we have been testing the line draw both via the help app and the phone dialer; and we have not had any problems. The lines are continuous and none of them went in crazy directions. Yes I know it is still early but I am hopeful that HTC has gotten this under control. Being they were so quick to suggestion my had a hardware defect, I am wondering if they are not aware of the issue.

For reference here is the GOOD date break down, it was assembled about 4 weeks ago.

FA = Taiwan

7 = 2017

8 = August

3 = third day

And now for the Bad news.... The repair facility where we need to send our Phones in for repair is in Houston, TX. From the reports of hurricane Harvey, I think I am going to be holding on to mine for another week before sending it in. I will check with their support team mid week to see what they suggest, but I bet it will be an extra month before it will get repaired now.
[HTC U11  Questions & Answers] themuffinman:
Downloading the latest update on the sprint model, hopefully there is a fix somewhere in this update. Will report back later with my findings.
[HTC U11  Questions & Answers] themuffinman:
After 24 hours of use, my touch screen issues are still there. Its annoying when it occurs but it doesn't happen enough for me to lose my mind. So I think I will deal with it for the time being.
[HTC U11  Questions & Answers] Doughnut:
Ok I'm in contact with HTC over this, so far they've suggested touchpal as the issue, which it's clearly not, as both gkeyboard and touchpal behave the same.

I've sent them a link to this thread.

---------- Post added at 12:08 PM ---------- Previous post was at 11:54 AM ----------

Well it didn't get anywhere, just told as I'm within 28 days to return/exchange.
[HTC U11  Questions & Answers] jopomopo:
I had to do factory reset because of this problem. It's much better now, although not perfect, I'm still on 1.13.401.1 firmware.
[HTC U11  Questions & Answers] Doughnut:
Clearing the cache partition helped me but the problem is still there. The demo unit in the store was doing the same thing on almost every touch, so the assistant manager decided it's normal. Though it was running the earlier build to the evidence is stacking up that this is improving via firmware updates - not that I doubt what's been said in this thread, more evidence is helpful.

HTC have confirmed by Twitter it's not normal and if it persists to go for a repair.

I'm going to wait until the next firmware release which will probably take me beyond the 28 days, but given both my units, plus two store units are doing the same, it's more and supporting that it's a software issue.
[HTC U11  Questions & Answers] djbutter:
Anybody know when the latest update arrives for the unlocked US U11?
[HTC U11  Questions & Answers] jalomas7:
Hey guys, I too have had this issue and thought I was alone. I had believed this to be a software issue as well, and being a software engineer, wanted to get to the bottom of it. it may be too early to tell, but if you have Nova launcher on your phone, I may have a fix for you. Go to settings > accessibility > Nova launcher, and turn it on. The problem has immediately stopped and it's been a full hour since I've had the issue, even when trying to intentionally trigger it using the above mentioned methods. I'll try to come back in a day or so to see if anything changes
[HTC U11  Questions & Answers] killa_byte:
Hi, My software number is 1.13.401.1
[HTC U11  Questions & Answers] jalomas7:
Well, it's been 24 hours since the last time it's happened, so maybe that fixed it
[HTC U11  Questions & Answers] Doughnut:
Hey, would you mind doing the HTC line draw test and see if two points in succession draws a straight line?

I tried your method, and I found the lines join up more frequently but didn't give it enough time to test the actual typing performance.
[HTC U11  Questions & Answers] Doughnut:
So I'm on 1.27 now, and I've done the line test again and less lines are registering on touches in succession and typing performance is a lot better. I've typed this message super quickly and have had no sensitivity or ghost touches.

It turns out it was a software issue :) happy days.
[HTC U11  Questions & Answers] victornrey:
Try this

Go to settings> accessibility>touch & hold delay = medium. It will help.
[HTC U11  Questions & Answers] ibolito:
Still having this issue and it started to happen more often every day. It drive me nuts. I live in France and this country's HTC repair service is one of the most horrible in the world... Don't know what to do, I tried everything you suggested in this thread...
[HTC U11  Questions & Answers] 0x6e697247:
Updated to 1.27 today (UK) the issue seems to be fixed! Hopefully it stays that way :)
[HTC U11  Questions & Answers] TailsNeon556:
I hope this update comes quick in the US and fixes this. This issue is starting to get quite annoying.
[HTC U11  Questions & Answers] ibolito:
Well guys I might have found something. I just flashed a custom kernel (ElementalX-U11) and the issue it's gone for now. It's the first time since the problem appeared that I run that long without having it. It might help you.
[HTC U11  Questions & Answers] djbutter:
So i didn't have the problem for quite some time after i removed my plastic screen protector (previously i used a tempted glass one). I decided to put another back on (micro scratches!), And almost immediately the problem started to happen again!

I just removed the screen protector again, and the problem has all but disappeared immediately.

I guess I'll have to settle with micro scratches, and live life without a screen protector.
[HTC U11  Questions & Answers] Doughnut:
Have you tried a film type protector, e.g. ultimate shield clear guard? I'm using one and it doesn't cause any issues.

But I had the issues no matter which screen protector or a naked screen.

Have you got the 1.27 update? That's done away with the problem for me and others have reported the same.
[HTC U11  Questions & Answers] djbutter:
I don't have the 1.27 update yet (has anybody, with the unlocked US variant?).

I do love the feel of the phone without a screen protector tho. Makes me wonder if i should put one back on....
[HTC U11  Questions & Answers] scotia_rfc:
After update to 1.27 i haven't had the issue of the notification bar dropping down, but i still have the problem of the keyboard collapsing while i am typing. I'm using SwiftKey tho not TouchPal.

Might do a Clear Cache/Clear Data on SwiftKey and see how that goes.
[HTC U11  Questions & Answers] pccma:
Let me share my experience on my 2 months old U11, which has been pretty terrible. Firstly, some details of my phone which may be related:

1) Rooted with Magisk from day one

2) Using Spigen Glass Protector

3) Software number : 1.27.400.9

4) Build number : 1.27.400.9 9.0_g CL952087

5) Using the stock launcher

6) Tried both Short & Medium in Accessibility - Touch & hold delay : didn't help

7) No background task killer

About 2-3 weeks ago, I started having all the problems which are reported in this thread 1) keyboard collapsing - I'm using Swiftkey, 2) notification panel suddenly coming down for no reason. Then, there was an OTA firmware upgrade which I tried and failed (presumably because of the Magisk root, I'm used to the Chainfire rooting method so I'm not sure exactly what I have to do). Anyway, I gave that up and every now and then, the new firmware update message would pop-up which I simply ignored. About a week (or may be 10 days ago), there was a Magisk upgrade which I did and was successful. Since it completed pretty smoothly so I though maybe I'll try the firmware upgrade again and somehow, it said there is no current update available for my phone so I guess the "half-done" firmware upgrade may have went through together with the Magisk upgrade.

Then a week ago, the problem started to get *REALLY* worse. In addition to the problem reported in this thread, it would now sporadically act like a "ghost" phone. Even when I'm not touching the screen at all, the notification panel will keep coming down and options from there would be chosen randomly (as if someone is clicking on them). In order to see what's really happening, I turned on the "Glove mode" (note that I did this after the new problems popped up) as that sort of gives you a cursor when your finger touches the screen. When the problem is happening, I can see the cursor just keeps flashing randomly towards the top of the phone (i.e. repeated clicks). Note that this happens even when I'm not holding the phone (and of course, not touching the display).

Rebooting also doesn't help at all and this problem now happens around 50% of the time I'm using the phone. However, sometimes it would stay normal for a whole night. But overall speaking, it seems to be getting worse. And, the line test will totally fail when the problem happens (i.e. whatever I draw, it just keeps drawing by itself in the top region of the display).

Really not sure if I should get back to a Samsung instead...

Regards,

Paul.
[HTC U11  Questions & Answers] aristidis_halk:
when you say collapsing you mean lag? if yew i have the same problem...when i'm typing lots of words after a while it just lags for 2-3 secs...i use g board... updated to 1.27 and the problem is still there..i hope it is software problem because htc doesnt have official service here in Greece...
[HTC U11  Questions & Answers] scotia_rfc:
No I have no lag. The issue is when I am typing the keyboard will randomly disappear, collapsing down. I then have to tap the text area again for it to appear.
[HTC U11  Questions & Answers] aristidis_halk:
i dont have this but something else..anyway its not so serious and i hope it stays that way...
[HTC U11  Questions & Answers] AarSyl:
Do you have the Flow Typing enabled? If not, then SwiftKey defaults to gestures; swipe back to delete, swipe up for upper case, and swipe down to dismiss the keyboard.

Not sure if that's your issue (or if you knew that), but just maybe....
[HTC U11  Questions & Answers] scotia_rfc:
Well that looks to be my keyboard collapsing issue sorted!

I have been in SwiftKey options about 1 million times and I have never noticed the option to change between Flow or Gestures! How I have missed this I have no idea. I don't use flow to type so I'm guessing I have just ignored these options when in came across them.

Thanks for the info. Very appreciated.

No more issues for me now. Happy days!
[HTC U11  Questions & Answers] AarSyl:
No problem. You're welcome.
[HTC U11  Questions & Answers] mcwups1:
Does anyone have problems with tracers on the display? Or horizontal lines?

It seems like if I turn my phone upside down and wipe the screen off I have horizontal lines on my display.
[HTC U11  Questions & Answers] Philster2017:
U11 fix

Hi guys, I've managed to find a fix for this issue which seems to work, so far anyway.

Finally got talking to a guy in HTC who seems to know his stuff...

There are two important steps here it seems. Step one relates to the pre-installed message service via TouchPal. Step two below relates to calibration on your handset and charging system...

All are related (for some reason) to this problem.

Step One:

Settings > Apps> TouchPal > Storage > Clear Data

Step Two:

From the main home screen (normal boot up screen) of your phone, insert your ORIGINAL HTC phone charger. Press and hold the POWER button and both the UP and DOWN volume keys simultaneously until the two buttons on the bottom of the handset start to blink and the phone powers off... Release after this and allow handset to restart.

Mine seems to be fine now, although, the problem does happen every so often, however, hardly anywhere as much as before after I did the above...

Hope this helps, I'll update if the problem reappears.
[HTC U11  Questions & Answers] AarSyl:
What software version are you on? The newest firmware got rid of ALL of those issues for me, and I had it bad...
[HTC U11  Questions & Answers] Philster2017:
U11

I'm on 7.1.1 now, but since I did the above steps, the issue has occurred only 3 or 4 times, and hasn't happened at all in the last 7 hours :)
[HTC U11  Questions & Answers] AarSyl:
Sorry, I meant build number. I'm on 1.28.651.3. All software versions released for this phone are 7.1.1.
[HTC U11  Questions & Answers] Philster2017:
No hassle :) I'm on 1.27.773.7 just got confirmation that the above is the fix that HTC will do if the phones are sent back to them with the issue, so hopefully it will save anyone the hardship of having to send it back :)

I haven't had any issues within the last 12hours or more since doing it.

The problem is a link error between the charger, TouchPal and the screen..

I've gotten "off the record" confirmation about it.. I just hope it helps!

Incidentally, the typing screen area on TouchPal will change to black background once the above is actioned, you can change it back to white afterwards if you like, but apparently that's how you know the issue is resolved...

Hope all that helps!
[HTC U11  Questions & Answers] AarSyl:
That's very strange, because some of us (probably most of us) were not using the TouchPal keyboard when these issues occurred. For that matter, my phone was rooted, and I completely removed the TouchPal keyboard, and the issues would still occur. But that was all before I updated to the last firmware.

I honestly don't see why HTC can't simply burn the TouchPal keyboard and replace with GBoard. They have been in such close cohorts with Google for some time, and it would have been nice to see them at least put that.
[HTC U11  Questions & Answers] Philster2017:
totally agree! I really dislike TouchPal also, you've hit the nail on the head!

Not sure, maybe it had something to do with calibration on the screen? I didn't really ask as I was desperate to fix the issue without the need to send the handset off for god knows how long!

But yes! Definitely need to move away from TouchPal!!
[HTC U11  Questions & Answers] Doughnut:
So after my update to 1.27 all was fine for a week or so, and slowly the problem started to come back. Although this time it's a lot more around inaccurate touch registrations.

I don't use touchpal, but cleared the data anyway, and used the reset method as posted above.

It's sounding like a digitiser calibration issue...

Will update with my findings.
[HTC U11  Questions & Answers] tal_sarid:
I did have some problems with fast typing on 1.13 (caused a swipe here and then, very annoying) but after updating to 1.27 everthing works fine. (for almost 3 weeks)

I'm still getting this problem, and it's really irritating! It is the ONLY problem I have with the phone, but it happens really frequently.

I've tried all the suggestions on this thread, but no luck.

I am still on 1.16. When will the US unlocked variant get 1.27??
[HTC U11  Questions & Answers] jimwhoisfat:
same issue

I have had these same symptoms, notification shade coming down when hitting certain areas of the keyboard and keyboard disappearing randomly. Additionally, I've noticed that sometimes when long-pressing on letters to get symbols, particularly '?', I instead get multiple short presses i.e. 'nnnnnn' instead. Using Touchpal. Very irritating!

What rom are you using? Are you sure that it is based on the latest firmware? If so, you might hav a problem with our device itself.
[HTC U11  Questions & Answers] djbutter:
I'm using the unlocked stock version.

I had a chat with HTC's support. It turns out that, for me, it was a software issue. As soon as I booted into safe mode (without any third party apps), as suggested by the rep, the problem magically disappeared. I was pretty surprised. I tried everything that was mentioned on this thread, except for that (and a factory reset).

That was a few days ago. My phone has been working flawlessly since.

Hi

Anyone still having the issue ?
[HTC U11  Questions & Answers] ChickenDancer:
Yup, on 1.28.617.6 on a Canadian 6GB model. Seems to be most easily reproduced when pressing the left shift key.
[HTC U11  Questions & Answers] ChickenDancer:
So, I spoke to HTC and they suggested flashing using a RUU from their website. Seemed to work at first but within 12 hours it's back to being problematic.

For me there is two issues:

1) touching the bottom left of the screen results in another touch appearing on screen underneath the earpiece, it's always in the same place.

2) touching the bottom left of the screen but about an inch inside in both directions (as if you were hitting around 'f' on the keyboard) sometimes results in no touches at all being detected.

Not sure if it's hardware or software, but thought I'd post in case it helps someone.

[HTC U11  Questions & Answers] Toyeboy:
Chatted with HTC. He thinks it's hardware in my case. There's a spot on right side of screen near bottom that if touched will trigger the middle of the top of the touchscreen a ghost touch, which pulls down the notification bar. Which obviously makes the phone unusable. 4-6 weeks for the repair in the USA from the day they receive it. Crappy.
