I have my Fairphone4 now for more then 6 months. and after about 3 month the ghost touches began and got worse quickly. i bought a new screen (from my own money)
But now my new screen also start to have ghost touches.
I read the hack with the cardboard on the connector. but i really would like a response from Fairphone themself what they think of this hack before i am gone apply it, did they ever react to it ?
FP4: Same problem here. Started 11 month after purchasing. Random touches, not related to charging.
I opened a case with Support, and also ordered a new FP4. I need this for work, so there is no other option for me, I can not risk this getting worse while on a trip.
Hi Warzel, yes, they are reacting. But with same useless answers since at least half a year now. They are analysing it, working with the phone manufacturer, yada yada.
I meanwhile believe there will be no official solution anymore. I am Sure they meanwhile understood whats going on, ridiculous to believe they still didnt. However the solution might be not feasible for reasons which they keep internal.

My ghost touches are back after reseating and adding tape. I am betting that this is an issue with the touch screen mapping and the camera cut out. It may be a firmware issue with touch area mapping in that area. Does popping the battery for a while fix it the same as the connector reseat? Wonder if it’s an accumulative problem or error state in the touch screen controller.
Edit: I have sent in a support request documenting my problem and letting them know I cannot recommend their product with this problem. Please contact support even if you cannot request warranty or aren’t interested in a repair. I would like to see some communication about the issue.
Surely we could fix this in software by detecting and ignoring spurious input

The pressure has to be high.
No ghosttouches for over one month weeks. Conclusion: The pressure should be quite high, otherwise it does not work.

Indeed, I applied my foam sticker 5 months ago? Never had ghost inputs again. Have a nice day my friends!

Just switched from 0,6 mm insulation tape (4 layers) to 0,9 mm card board. let’s see.
And wrote another message to the support asking for an update.

I asked support about the connector pressure hack, they replied: “We don’t advise the repairs that were mentioned on the forum” instead i was asked to sent in the phone for diagnose and repair, i will do that.
yeah, sent in my phone for “diagnosis and repair” in December. Received a replacement phone which started ghost touching in February or so. Means still in December they didnt understand whats going on. Also Never heard anything on what they diagnosed on my initial phone. I would strongly recommend them to tell us what solves the problem rather then what in their mind does not work. Yesterday another idea came up how to increase pressure in this case (not on the connector but on Fairphone).
Update: In the answer to my recent request fairphone now stated that meanwhile they found a method to repair the ghost touch issue. Dont know since when they offer this, they didnt inform me despite my open ticket…
@Warzel and anybody else: did you sent in your FP4? did anybody already get it back and has experience with the results?

I did not yet sent it in. the phone has to be downgraded to stock ROM before i can sent it in as otherwise they may mark it as out of warranty. Customer support also implies the the issue might be related to me running a custom ROM. But i did a flashback to stock ROM before and that did not solve it.
I am also afraid that as the issue is not always there that i get the phone back with remark, nothing found.
I slowly start to regret that i bought this thing, even thinking of selling it as broken, cut the losses and move on.
I did not send my phone in. After my post in this thread the problem has only showed up around three more times. And only one time the last 10 days or so.
It’s very curious, but not a big problem for me currently.
So I’m basically only logging data about the glitch when it occurs for me, and if it starts increasing in frequency again I’ll disassemble the phone and take a look at the connector.
After very regular ghost touches progressively getting worse I added several layers of tape, there is pressure noticeable on the screen.
The ghost touches stopped for about 7 weeks, they have now gradually returned, only once though have I seen the blue touch line down the lower center.
It’s looking like a repair job.
I too have this issue. I traveled to Germany on vacation and ordered a replacement screen while I was there. I replaced the screen around April 10th and the glitching started again with the new screen about three weeks later. I thought it was just me.
I have my Phone back and they appearently replaced the entire screen. Lets see how long that will last.
At least this issue gave me the opportunity to run iode OS on the thing now.

Hii all,
So my fairphone 4 seems to have problems with the software. The phone is suddenly pushing buttons itself and the screen is moving without me doing anything. I tried reinstalling the whole phone since I suspected that is was a virus, but the same problem is back. Have you had this problem?
All the best,
Sofie
Known issue, see here:

@Sofie_Meyer @KurtF I’ve moved your posts here to a thread about ghost inputs.
Looks like it might be an idea to check the screen connector, see above.

Hi, Han, could you pls share what the result after you add extra form on the pad? I wanna know if that can work. thanks.
I haven’t had ghost inputs since I applied the foam sticker 5 months ago.
It’s important that the pressure is high enough.
Kind regards
