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: [+2025-01-27T21:49:20+00:00[Europe/London][ca-iso8601]] I post this here to acquire corroborations. Does anyone notice this …

[image] rokejulianlockhart: Considering I live somewhere rural, with (consequently) potentially unstable mains voltage, 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 believe that this must be the…

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 b…

[image] Nabalazs: As I’ve previously encountered a bug, where the phone keeps showing it’s charging, while it’s actually not plugged in. @Nabalazs , good point. I saw the same on the same charger setup: [image] Nabalazs: I noticed those same touch inconsistencies like if I was charging.…

I can reproduce on my brother’s fp5 , too: [+2025-03-25T20:04:46+00:00] 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 …

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) [Screenshot_20250328-130559~2] And happens waaaay less, or almost never when I use a fast charger with a C-C …

@Nabalazs , thank you! That’s really helped. I’ve sent the undermentioned to Support: I even managed to demonstrate, in one video, the difference between the PSUs: [+2025-03-28T13:11+00:00] …and yes, that second room is my brother’s. Tidying is not a competency of his.
