Digitizer Input Without Touch

[dt.white 62]

OK, so not sure if this is actually a bug or not, but need to see if anybody else is experiencing this issue.

Note: my device has never been dropped, and this behaviour started yesterday evening. Multiple reboots have not resolved the issue.

Essentially, whenever I'm using my device, it intermittently registers multiple touches along a single line of the digitizer, causing completely unanticipated behaviour which as you can imagine, is very frustrating and makes the device very difficult to use - I even had difficulty recording it! (but I managed). Please see the linked video file, which I recorded. Note I've turned on both the options for seeing touch input (user and developer) to give as much detail as possible.

If anybody else is experiencing this or has any ideas as to what is happening, please let me know.

Thanks

Thanks @david

@michal@hanu.la did you get your issue resolved?

[silversolver 849]

This sounds like a physical glitch in the digitizer. I get this from time to time with my Droid 4 as well, and turning off the screen and wiping it on my pants has so far resolved it every time. If it is persistent and/or stubborn, I'd definitely see about getting it warranty replaced once things get back to normal in China. If you don't wait until then, you'll likely be without it for some time.

It is definitely persistent so I've contacted support, they will be sending out a replacement screen with instructions on how to replace it.

I had the option of sending it the phone off to a centre in London but decided I'd give it a go myself instead (I like a little tinkering).

Will update this post when it's replaced to advise on the outcome.

Thanks for any details you can give us on the process of what it took to replace it and how it works afterward.

My phone has developed the same problem 😞
Was it easy to replace the screen?

 

[dt.white 62]

@hka I'm still waiting for delivery of the screen replacement, I've just chased this up with support.

I am no longer experiencing the original issue of multiple registered touches - it has now evolved into simply being a dead part of the screen, approximately 8mm in height, so I am just working around that (useful to have a keyboard!)

Ah I see, yeah I am in contact with support, will have to see were that leads. Temporary solution is to use an app I found called "Partial screen" it supports putting touch masks over the screen, but they are not transparent so now I have an 8 mm high ribbon over the screen where I cant see, would be better if it was just dead and not phantom touches.

Just to update everyone - I have received a new screen through the post this morning. When I get a chance I will attempt to replace it and video it for reference.

i just replaced my screen a few days ago - wasn't hard at all, see here. i followed for that TeZdevice's advice here.  you can do it in less tan half an hour.  my screen & digitizer worked thereafter flawlessly. 

the reboot also brought back some sound effects such as the glang when charging - which implies that Android isn't as stable as a full-fledged unix box.  my linux-based Nokia N900 was rock-stable and robust with uptimes up to a year or so...

OK so I've replaced the screen - thanks @pistikem for the references. I did film it but not sure it's worth uploading as the guides above are of much better quality.

Unfortunately, it appears the screen I've been sent has problems. While it's solved my initial issue, I've now got two "dead" zones running down each edge of the display, left and right. The reason I use the quotations is that it registers touch if I drag out from the middle of the display, but doesn't register a direct touch or dragging in from the edge of the display, which is most peculiar.

I replaced it again with the original just to make sure that I hadn't done something wrong, got the same original issue. Then replaced again with the new screen, and got this edge touch issue again - so nothing to do with the way I'm installing it I believe.

I think I'm going to have to request another screen, which is very frustrating given the length of time to receive this one..

[dt.white 62]

Just to add as well - I've also got light bleed around all four edges which I noticed last night once it was dark. Definitely going to be requesting another replacement, and going to put the original back on for now as it's more useable..

See attached video for a demonstration of the "dead" zones with new display.

Doesn't look like right. Maybe have been damaged in transit. We'll send another one. Will discuss with you over email.

So I've now had an email from support which is basically insinuating that the engineers don't believe the video and that some software has been applied to cause the touches from the edge to not respond. This is pretty insulting and not a good look.

I will be refitting the replacement display and taking a video of the device to show the light bleed too as that is apparently what is required to convince F(x)tec that the display is faulty.

@Erik @Waxberry As a backer for your IndieGoGo campaign and therefore a loyal follower of your company up to this point, I think you need to address this. Frankly, it stinks.

[Slion 1,201]

@dt.white Sorry you are having so much problem with your hardware. You are not the only one unfortunately. Hope you get this sorted soon though to be honest considering FxTec current work load I doubt it.

I know there are a lot of hardware issues @Slion and it's not that which is the problem - it's the insinuation that I'm essentially lying in order to get another display..

[dt.white 62]

OK, so I received my third display recently after a reversing of the decision by support to only send out a display after me taking a video of the second display with the light bleed.

I am happy to say that this display is much better performing than the first two, however it still appears there are some, albeit small, dead zones at each side of the display. It does mean though that it is usable and I think that's the best I can hope for - would be interesting to see if other people who don't have a problem with their display notice any kind of dead zone on theirs?

For reference, I've uploaded the videos for each of the displays (1,2,3) based on the order in which I received them, 1 being the one originally shipped on the phone, which you can find at https://1drv.ms/u/s!AvH5kRgzlbHGh90jura1HONnjRAIcA?e=Kd0eJT

What program do you use for testing?

I don't see any problems with my display at all.

You're just rubbing it in now! 😒😂

I got a replacment screen from fxtec and it also has small deadzones at the edges of the screen. Maybe 5 mm wide. But they aren't really dead because they register swipes when I move from the middle of the screen towards the edge. But doesn't register if I swipe from outside an in, or try to press buttons close to the edge.
