📱 Poco X5 touch freezes for a few seconds every time I plug in the charger

I have a Poco X5, bought in March 2024 for 14,999 rupees, running the latest update it has offered. Since about three weeks ago the touch screen stops responding for a few seconds whenever it is plugged in to charge. It happens with the original charger and the cable that came in the box, but I noticed it more when the battery is below 30 percent. The screen still shows everything, and scrolling just freezes, then jumps ahead. If I unplug it, the touch comes back in about two seconds. It does not happen when the phone is on battery, even if the battery is at 5 percent, which is why I do not think the screen itself is damaged. It started the week after I installed a new camera app, so I wonder if that is related, but I removed the app and nothing changed. What I have tried so far: restarted the phone twice, removed the screen guard in case it was the guard, wiped the screen, tested with my brother's charger (same problem, a bit milder), and cleared the cache for the launcher. I also did a quick test in safe mode, and the problem still happened there. I have not done a factory reset because I have around 9 GB of photos that are not backed up, and I would like to avoid that unless it is truly the last choice. The service centre in Abids said they would charge 1,200 rupees just to look at it. Has anyone seen this on a Poco or a similar phone? Is it a charger grounding thing, or a software bug that a later update will fix?

I would not rush into a factory reset. A friend with a Poco M4 had touch freezing only while charging, and it was a screen protector with a thick edge pressing near the bottom edge of the display.

My Redmi Note did this with a cheap cable from Charminar market last year, touch went weird for seconds. Your original charger rules that out, but your brother's one being milder makes me think it is the battery level. Did you try charging with the phone fully switched off for one evening? If touch is fine afterwards, I would blame the software and wait for the next update before paying 1,200 rupees at Abids.

I had the same freeze on a Redmi last year, and it turned out to be the wall socket, not the phone. Our old extension board had no proper earth, so the charger made the screen jump around. Try a different socket, or plug into a laptop or power bank for a day and see. For me it vanished the same evening, and I never needed a reset. Back up those photos anyway.
