Last time I got a new screen from fxtec and replaced it myself. Sent a mail to support again and asked if they could send another one (and if they have checked with their supplier about fixing the root cause). 4 Quote Link to post Share on other sites
Hook 2,821 Posted January 10, 2021 Share Posted January 10, 2021 They turned me down for sending a display after first considering it. They indicated that they are no longer confident that just replacing the screen addresses the underlying issue. Hence, my Pro 1 is now at their offices. With a number of these issues popping up, they may want to do a more thorough investigation. Doesn't mean it won't turn out to be the display, but I think they want to look more deeply into it. Hope you do get the new display, however. 3 Quote Link to post Share on other sites

When I have replaced my screen with one bought at Aliexpress, I have noticed some dust at one of the shorter sides. I think it may be in connection with the problem... or may not. However, that time official support did not seem to be interested... Anyway, if I will have a similar issue with my current display, I may try to replace it with my original one first... 3 Quote Link to post Share on other sites

It's possible, but I would expect the effect of that would be more along the lines of causing touches to be inaccurate. That used to happen a lot with Palm PDA digitizers and the cure most times was to run the corner of an index card carefully around under the bezel. But, as I say, the effect was to make the digitizer inaccurate (you would tap one place but it would be interpreted as tapping at a different location). Not clear why crud would trigger an avalanche of touches across the screen on it's own, while just sitting on a desk. Not saying you are wrong. Just raising a question. I'm certainly not an expert on any of this. Edited January 10, 2021 by Hook 2 Quote Link to post Share on other sites

I am also unsure and that is also a reason why I have not disassembled my phone again for testing - that is my daily driver... However, the dirt ("pocket dirt") seemed to be relatively high amount and I am also unsure which short end was it. However, the problem was closer to the bottom end and when I have pressed the lower left corner, ghost touches have disappeared or improved for me for a while. So I am also just guessing but as more people having the same issue, it would be more important to know the valid reason... I still think it is most likely a display issue, but if the assembly process is similar, a similar gap may exists of different phones and dust may cause jokes... so it simply may worth a try. 2 Quote Link to post Share on other sites
Hook 2,821 Posted February 5, 2021 Share Posted February 5, 2021 Just to tie my story up, just got an email from FX that they have replaced my display and are shipping it back to me (FedEx to US). Only a month, I'm very happy! 😄 I was worried with lockdown it would take longer. Thank you, FxTec. 5 1 Quote Link to post Share on other sites
altwouss 22 Posted February 9, 2021 Share Posted February 9, 2021 (edited) So unfortunately, the same ghost touches started happening to me yesterday. I was hoping it would be related to the cold after I had been outside. (Currently everything is covered in snow here). But after using the factory kit I have noticed that I am having the dead touch row in the same position as well. Got mine in February last year.

Now that Fxtec has repaired a few devices with this problem, do we know more about the cause? Is it just a failure of the display or is it some failure caused by the proximity with other components (design failure)? Edited February 10, 2021 by OKSun 1 Quote Link to post Share on other sites

We don't know what they have found, but it is clearly display-related problem - most probably a display fault, but I may think also a small possibility which may be fixing related... ...but it is clearly not related to other components and I don't think it is a design failure. 1 1 Quote Link to post Share on other sites
ToniCipriani 194 Posted March 30, 2021 Share Posted March 30, 2021 Looks like mine started doing this. Playing Mario Kart on landscape mode with slider open, finger is nowhere near the top (right edge in landscape), the notification shade would just randomly open. 2 Quote Link to post Share on other sites

May take a while before it goes crazy. I could trigger it by pinching the top right (in landscape--bottom right in portrait), somewhere to the left of the camera button. At first, pinching would just fire the phantom touches once. Then, as time went by, it would trigger a phone possessed. If you get that, capture it on video to include with your warranty repair request. 1 1 Quote Link to post Share on other sites

OK I think I managed to reproduce it. - (Optional) open slide and set phone on table (had to do this, only got 2 hands to hold camera and trigger problem, lol) - Open Calculator - Slide finger alongside the bottom of the screen (right edge when phone is open), outside of the actual touch area - Watch the Calculator go crazy It's actually along the whole edge, not just the corner. When in portrait mode, it randomly triggers the "7 8 9 Divide Backspace" row. Edited March 30, 2021 by ToniCipriani 2 1 Quote Link to post Share on other sites

ToniCipriani 194 Posted April 3, 2021 Share Posted April 3, 2021 (edited) Just a small update... The ghost touching got to a point where the phone was unusable and I couldn't even enter my pattern at boot without a lot of retries. Also got a bit dangerous yesterday when I was using my phone as GPS and it kept randomly switching out of Waze. @Hook posted some troubleshooting steps done with F(x)tec so I thought I give it a try (specifically checking if any flex cables were loose), and it SEEMED to have helped. I followed gelraen's teardown instructions and took the screen apart. Cables seemed tight, but I went ahead and reseated both the LCD/Camera to mainboard as well as the LCD to adapter cables. Specifically this one: I will need to do more further testing but it seemed to have passed the calculator test above, and I was able to enter my pattern unlock fine. Going to keep my ticket open with F(x)tec for now, don't think they are responding till Tuesday very least anyways since it's Easter Monday in UK likely. If this fixes it permanently, maybe adding some foam tape to avoid that connector from moving/coming loose might be an idea as a preventive.

Please also post your later foundings about this issue. It has not helped in my case, but it may happen you only had this connection issue. It may also happen it will start the same problem again. That is the connector of the screen itself anyway. 1 Quote Link to post Share on other sites

I reseated all 3. Thing is though, none of them felt loose or anything. I'm actually kinda surprised it worked. 2 Quote Link to post Share on other sites
ToniCipriani 194 Posted April 5, 2021 Share Posted April 5, 2021 ...and the problem came back. Although it's not as serious as it was before the attempted repair. Maybe just 1 false tap in a short while. Still usable at the moment. 1 Quote Link to post Share on other sites

I even got fooled by the coincidence of installing AICP and the demons, as I called them, went away, I think it was for a couple of weeks, but then they came back full force, like they had gone off to training camp and my Pro1 was unusable again. 1 Quote Link to post Share on other sites

I've seen some earlier posts suggesting it might be due to static charge. I wonder me reconnecting it would have discharged some of it, thus making it work properly for a few days. However it is odd that it's only along the bottom though. Top end seems perfectly fine. 1 Quote Link to post Share on other sites

Foop 5 Posted April 9, 2021 Share Posted April 9, 2021 Hey folks, I'm dealing with the same thing, maybe? I've always had phantom touches when charging from an AC adapter, but about a week ago, I got a 10mm wide band right about where the number row in the on-screen keyboard is, that doesn't respond to touches. FxTec told me to send the phone to them, and that they would turn it in at least a month, or maybe longer... So, 2 weeks shipping over, minimum 4 weeks in UK, 2 weeks back, and my 6 month old phone is out of my hands for 2 months? That won't work for me. Where can I buy a replacement screen? (Also my microphone just took a crap. Any idea where I can get a new microphone module as well?) 1 Quote Link to post Share on other sites
