You can see an example in the undermentioned – at first, I demonstrate it unplugged, then plugged, the unplugged again. The difference should be evidently shark:
I post this here to acquire corroborations. Does anyone notice this occurring on their device? Considering that my fp4 used to ghost too, before the firmware update remediated that, I shan’t be surprised.
That doesnt look like Ghost touches? While charging the screen def is less responsive. Preety sure this was mentioned somewhere, should I find it will link or merge.
Ah, damn. Perhaps it’s because my charger might be ungrounded:
@yvmuell, it is occasionally less responsive, in that inputs don’t go through. However, more so, it merely loses input almost immediately. Thanks though.
Certainly, the smartphone does not become slower.
Are you noticing a difference – while charging – between having the FP5 lie flat (e.g. on a desk) and holding it in your hand? Having the phone lying on a flat surface is typically known to deteriorate touch sensitivity.
I was running two SATECHI USB-C PSUs, connected via IEC 60320 cables to BS 1363 (EU designation “G-Type”) plugs. One contains 6 USB ports, and is connected to the mains via C5, the other contains 4 USB ports, and is connected via C8.
Somehow, resetting the power output configuration by connecting a new cable into the 4-port (C8) brick seemed to fix this issue, despite me being connected to the C5 one. I’ve tested it for 5 solid mins to ensure that it’s not placebo, but you can see for yourselves:
I have no idea how this is possible.
@urs_lesse, thanks for the advice. I noticed it in my hands. Though, why would it being horizontal (or on a table, whichever you mean) cause that?
The unresponsiveness whilst lying flat on a hard surface is something users have kept reporting over the years. I notice it myself from time to time (on my FP3 though).
Not anymore. Consequently, I’ve been reading about grounding, and it appears that even if something somehow fails in the grounding process, the device should be protected against this if it’s properly insulated. Evidently, the fp5 isn’t Class II, despite its bulk.
Considering that all BS1363 sockets are 3-pin grounded, and all C5 connectors are too, does anyone have any ideas whether the grounding really could have failed (versus this being a fault of my device)?
I live somewhere rural, with (consequently) potentially unstable mains voltage:
Consequently, I’m wondering whether I need to hark back to the time of 90s PC PSUs, when an (EMC?) filter was necessary to ensure that it wouldn’t explode. I’ll attempt to measure whether this applies. [1]
I believe that this must be the cause, for as suddenly as it appeared, it disappeared. The reconfiguration earlier appearing to remediate it was a coincidence.
Fascinating. I’ve never managed to screen record it happening so clearly.
But I’m still strongly convinced that this is a software issue, not a hardware one.
As I’ve previously encountered a bug, where the phone keeps showing it’s charging, while it’s actually not plugged in.
And I spotted that behaviour because I noticed those same touch inconsistencies like if I was charging.
So it can’t be any sort of grounding. It happened even when away from the wall.
@Nabalazs, good point. I saw the same on the same charger setup:
Thanks. Filed at FP’s ZenDesk: support.fairphone.com/hc/en-us/requests/1250205.
Thus far, I’ve seen deviations from ≈ 245 to 252V:
[1]…which is the upper bounds of expected (<253V). [2] It reproduces at both, and never when not charging.
I can reproduce on my brother’s fp5, too:
It took me a moment to realise that it reproduces better when I move slower, and I apologise for the vertical upload orientation. Blame iPhoneOS.
This so perfectly shows the experience I’m having. But for me it’s maybe less egregious. It only happens with some touches, and I’m gaslit into thinking I’m just touching my phone wrong.
@Nabalazs, I’ve reason to believe that it might be due to my charger, since although it reproduces on my brother’s device when it’s connected to my charger during the random periods when this applies, it doesn’t ever appear to occur when connected to his.
Consequently, are you able to test whether it reproduces on another of yours? A different model, ideally. Additionally, does it solely occur at random times of day for you, too?
Now that you bring this up, it happens way more when I use an older charger with an A-C cable. (The C port on this charger was always acting weird, that’s why I only ever use it’s A port)
And happens waaaay less, or almost never when I use a fast charger with a C-C cable. I always plug into port 1.
As of random time of day… Not really? Happens any time I plug in, as far as I can tell. But I never really paid attention to it, to be honest.
@Nabalazs, thank you! That’s really helped. I’ve sent the undermentioned to Support:
This is surely not happening to your phone only, but this is not a widespread issue. I can say this confidently as I also use this phone and I have no problem.
Per more specific corroboration from other users at
forum.fairphone.com/t/115559/17and further testing of both my and my brother’s devices, we’ve established that this solely occurs on certain charging bricks. That would explain why you and many others do not experience this.I can bring this to our tech team, but the reply will be the same.
Consequently, even if tentatively, please ask your technical team to investigate this. They should be able to reproduce it with the undermentioned:
amazon.co.uk/dp/B0BXFFYHG7: 1 × EU-designation G-plug (BS 1363) version of SATECHI’s 6-Port GaN AC IEC 60320 C8 to DC USB-C PD charging brick (aST-C200GM-UK).
amazon.co.uk/dp/B092DP63ZF: 1 × CLEEFUN’s 3M 60W USB-C PD to USB-C PD cable.I ask because if this isn’t merely an issue with specific devices (it not being so is how this appears to me), then my smartphone shall sit in your warehouse whilst they test it, unable to ascertain what to fix because their charging equipment doesn’t induce the problem (else it would have been discovered during QA).
To demonstrate, this doesn’t occur using the same cable on the 4-port version (a
ST-UC165GM-UK) fromamazon.co.uk/dp/B09QRN64HB.You can see this reproduced perfectly at
youtu.be/ylwYYrjzGmU. It includes a continuous demonstration of the problematic and operative PSUs.Please note that I continue to maintain that this is a problem with the FP5, because it doesn’t reproduce with my iPhone 11. I can test this on an FP4 too, though, if of use.
I even managed to demonstrate, in one video, the difference between the PSUs:
…and yes, that second room is my brother’s. Tidying is not a competency of his.
Support purports that they’ve evaluated my combination and can reproduce the problem, but have informed me that they are certain the fault is with the charger (even though it solely affects my FP). It’s a very unsatisfactory response, but when I’ve purchased and been refunded for the equipment they intend to send me in order to confirm it’s not my device, I can at least take this to SATECHI.
Not sure if it helps. But I have recently had issues with my phone charging and display. I was not even able to unlock a phone as the display did not record my touch properly.
It’s a new office charger and it seems it never happened before to my phone with any other chargers.
