Ghost inputs on FP4

Hello, Fairphoners :wave:

I have had the ‘Ghost Input’ issue for several months now. Fairphone initially offered to have it looked at and repaired - but have since offered a replacement phone.

(I don’t have much to add to this conversation - but felt I should add myself to the list of people affected by this issue.)

Hopefully, the problem is sourced and Fairphone can amend these issues going forward. I don’t like the idea of receiving a second handset when I am trying to be more ‘environmentally friendly’ and conscious about electronic waste and fairer practices.

Has anyone found what is causing this?

I am still watching this tread

My FP4 is affected too.
I have already tightened the display screws, this seems to have reduced the occurrence of ghost input, but this is just a feeling, not a measurement…
I did create a support ticket and had to answer a few questions and to perform the display hardware test. Let’s see what the support suggests next.

Starting to wonder…how many fp4 out there have this problem…and is it the only problem.

Perhaps we can find out if multiple problems are related?

Was in contact with someone from Fairphone (that is not in customer service)
He said he knew about it…but thought it was uncommon.

My FP4 in affected for some months (2 or 3 times a day can usually stop it by turning screen off & on) but been too busy to try any of the proposed fixes, My Nephew got one a few months after me & his is also affected but to a lesser extent, few times a week.

I tried to count that :slight_smile: Ghost inputs on FP4 - #286 by peci1 . If there are any newcomers to this thread, please consider voting in the poll. So far, it seems there’s like 50 phones affected that are reported here.

But for example, my vote for rare occasions is kind of on the edge with no ghost touches. The only time I had them was when charging the phone from a gigantic ungrounded battery-powered inverter. I’m not really surprised weird things happened. And yes, yesterday when I was cooking on inductive cooker and laid the phone onto an (unused) induction coil. But the parasitic magnetism from the used one did also cause ghost touches (I rather removed the phone when I noticed). But I think this is the basic physics that can’t be circumvented with this touch layer technology.

oke, I experienced the ghost touches again, so the problem is not fixed after repair. And now i also saw screen dimming in full sunlight, pfff… FP4 :disappointed_relieved: Someone wanna buy it ?

Are you still using the original screen, or the replacement?

I now have the original first screen installed that had ghost touches, but that Fairphone is unwilling to refund/replace because they say the screen is not the issue.

I also have the ghost Touches and the dimming in Sunlight. After this Vacation i decided to bui a regular Samsung Phone because i can’t read at the Beach, no Chance. The Light is dimming ~80% but showing in Menu 100%

I have the “ghost touches” too. Is there a solution yet?

Just make sure to report the problem…the more people do…the more urgent it gets

sorry to hear that. Fairphone claims to have found a solution now. In case sending in your phone for repair is not acceptable for you I would bother them until they send you a replacement phone. I a testing a replacement phone now since several days and hope the issue is really gone…

Mine was replaced…tested the replacement for a few Days… working just fine…send the original back.

Few weeks later…,…the problems were back, now with Fairphone 5 round the corner I worry that the effort will not be 100% to fix the 4…

The FP5 roll out will have nothing to do with the FP4 resouces in my opinion. They just dropped the FP2 most likely to free resouces, so I would not worry that it detoriates further and ask overall to not start this discussion here again, as this already has its topic.

lets hope you are right, @yvmuell . I share @DJA concerns.

Received the foam stickers from Amazon mentioned in this thread and applied one full layer (4 side-by-side) to cover the original foam, then 2 more stickers.

For now the ghost touches are gone and more importantly, I don’t see the bluish imprints on the screen anymore caused by the electrical insulation tape (too thin has no effect, too thick causes stress on the screen).

We’ll see if the the effect wears out (when the foam doesn’t deliver enough pressure anymore).

I also filed the issue with the helpdesk, and they offered to send in the phone for a fix. So if the touches come back, that’s what I’ll do.

I just experienced ghost touches too. It happened twice in a matter of seconds, then nothing for a while, then again and it was quite severe. Damn. :scream:

Welcome to the club :unamused:

To stop it instantly…for a short time you can try pressing on your screen.
For me it’s just some (nothing crazy) pressure on the top half that does it…for a while

I was planning on adding padding as suggested, but as others have also experienced some of the screws were a bit loose. I tightened them instead and the problem seems to have disappeared (at least been fine for a couple of days now, used to have ghost touches daily or more often). So that’s a very simple thing to try as a first remedy.
