Software update: FP4.SP2J.B.086.20230807

Yes, but I noticed that when I try to use the rotation with 2 fingers in Google map is not moving properly. I got hard time to understand the system. I also try my my pockets paint app is not moving as any average smartphone with 2 fingers movement.


I have moved your post here as there was a fix done for ghost touches. So are you saying you have not have ghost touches before the update and now have them or is it more about the screen sensitivity as described above?

This fix really makes the touchscreen harder to control for me. Not when I’m in my (home) office, but after cooking, cycling, working out and things like that. Almost as if the sensitivity is perfectly calibrated for an office environment (probably where the devs live too :nerd_face:). But if you have some kind of temperature, moisture or dirt on your fingers, the screen becomes unresponsive. Am I the only one that has this?


I can confirm that after this update, the screen of my FP4 is much less responsive than before. I never had any issues with the sensitivity of the screen or ghost touches before the update, so it definetely made things worse for me.

Interestingly, when I hold the phone in portrait mode in an upright position (the usual case for me) the screen seems to work just fine like before. However, as soon as I place the phone on a table or any other flat surface, the screen becomes very unresponsive and barely recognices my finger movement anymore. Scrolling or zooming (e.g. Google Maps) becomes a pain, but also simple tapping e.g. to launch an app only works occasionally. As soon as I take the phone into an upright position into my hand, the screen seems to work fine again.

Can anybody reproduce this behavior?

I am on CalyxOS and Calyx devs shipped this update yesterday evening with no other changes to the OS.


Perfect update!
I had huge problems with ghost inputs!

So much so that the phone became unusable.

That is fixed with this update, thanks for that! :slight_smile:

There seems to be a broad range of experiences with the latest change as illustrated by the quotes above as the latest examples. What I gather from all those responses is that people who had no issues before now have a screen that is not sensitive enough and people who actually had problems are happy about the change.
For me this looks like a significant variation in the hardware (quality?) of the devices. If this is indeed true, then no static change to the way touch is handled will not work for everybody and a more fine-tuned solution would be required.

Personally, I had no touch issues so far and also did not receive the update, yet. My device also does not seem to suffer from the dimming issue, further illustrating the point that there seem to be very different qualities around.


Noted that as well, however I know this from the FP3 already, and at the end I dont care as long as the Ghost Touches are gone for others (I never had any), as I think those are more severe compared to this.


Update went well. For the record, I didn’t experience ghost touches before, and after an extensive 5-seconds test (!) I do not think my touchscreen sensitivity has been affected by this update. :sweat_smile:

My, Fairphone updates are bad for my aging heart… :laughing:


I guess we’ll hear from you in a few days about this issue :nerd_face: It doesn’t happen often. As mentioned, in a perfect office-like environment things work well.


12 posts were split to a new topic: Another random discussion about FP

To balance the discussion a little bit, so far I haven’t noticed any issues with scrolling, zooming or touch sensitivity in general. Even yesterday on a pretty hot day when my hands were really sweaty. Everything was as responsive as I would expect.


I do have ghost touch before. After the lastest update of ghosts touch is hard to enlarge the image and using the Google map rotation with 2 fingers.


I tried this, and there is definitely a difference between holding the phone and having it lying on a table. But for me, this has nothing to do with orientation.

If I hold the phone in my hands, the touchscreen works without any issues. If I lay it down, I can barely get the 2-finger zoom to work, like 1 out of 10 times. Interestingly, as soon as I touch the phone lying on the desk with my other hand, it works well again.

It seems like I am grounding it through the housing with my other hand or something.


I have just tested this with myself.
It works exactly as it should for me. It’s strange that it’s so different. It would have been great if the user could set the sensitivity himself, e.g. in 3 steps, for such different scenarios. Of course, I don’t know how to do this and it’s easier said than done.

I haven’t found a way to reliably reproduce the issue. My assumption is that it has to do with sensitivity, but maybe something else is at play.

Wow, this topic is convoluted with discussions that have nothing to do with the recent software update and its effects, both positive and negative.

Makes it hard to spot information about those.

Seems to be exactly like that for me, in all orientations.

Same for me, but only when the phone is placed on the table with no contact of my hands, just the fingers on the touch screen.

I agree, it is less problematic than ghost touches I assume, however it is also something that hinders the use of the phone. For example, when I place the phone in the car holder, I cannot control it by just touching the screen, I need to grab it with my full hand as if I was holding it to get my touch inputs recognized. Same when I place it on a table to show something to someone. I never had this before this update.


Indeed, while the phone is laying on the table, it is a bit harder to navigate it. I don’t mind it that much because 99% of the time I just pick up the phone. But it’s true that I used to not have to put as much pressure on the display when it was on the table. It seems to me that there is also a significantly reduced sensitivity in the middle of the display (where the ghost touches used to appear). But then again, when I hold the phone in my hand, everything seems perfectly fine.

It’s weird. I’m using the official protective case which should insulate the phone from my hand. There shouldn’t be that much of a difference. :smiley:


Okay, I was able to reproduce it by laying the phone on the table and removing the official cover. With the cover, the problem is much less frequent.


That depends on your local phone operator who has to approve the rollout for their network. Occasionally, updates are not rolled out on certain networks because of known issues that have to be fixed first. But give it a little more time, sometimes it’s surprisingly slow with some operators.
I have not received the update either so far (Congstar :de:/Proximus :belgium:).

I am using the official cover as well, but I don’t see any difference if I take it off. I assume this varies greatly with the conductivity of your desk, mine is a painted wooden surface.
