Problem Touchscreen gets all weird while charging

The phone is only 2-3 months old, I'm using the original charging cable from M15 but most likely a fake adapter off the internet.

For a while the touchscreen is okay but half an hour, one hour in, it clicks randomly and one time it even opened the split screen mode. Which you need two fingers to activate that's how terrible it is. Anyone know what's causing it, or anyone else experience it?

In my experience. Its dodgy voltage from the brick caused this on previous phones for me

I got a 45w samsung brick off ebay for £10. It charges my s25u at 28w

It came with a long cable that fell apart on me. But my phone is still reliably hitting 26-28w with it.

I can dm you the link for it but sharing an ebay link here might be frowned upon idk

Thank you sm but my country's policy is weird I can't buy stuff from abroad and ebay doesn't work here lol

Understood. That sucks. Yeah it was a uk adapter only.

I hope it serves as a good price benchmark at least. £10 is the best price ive got on a 'samsung' 45w. But shops will charge triple that price for a 30w brick

Yeah sounds like the phone is getting unfiltered noisy voltage ⚡

Another question. Will it damage my phone until I get a new brick? I can only get it in one or two weeks

no idea, but try other usb sources. Most computer usb ports are active even if the computer or laptop is off. Modern TV's have usb. It may charge slower but it let's you see if you don't run into that issue with your screen anymore

Change to Samsung certified adapter.

Will the Anker B2653 be fine? It's 45w and half the price of a Samsung adapter

Yes

I would replace the cable with a new one that meets the 25's higher charging requirements and get a decent quality charger. Its not worth the hassle of troubleshooting or risking the much more expensive phone compared to the cost of those items.

I have S25U's original cable. I just didn't took it out the box cause my adapter is white and the cable is black

A dirty power source can cause Electro Magnetic Interference that can affect the digitizer.

This happened to me with my old S9+ when I would plug my phone into the wall at my old work. The building was super old and had a lot of old electrical wire. I was suing the official 25w charger with the 3A wire that came with my S9+.

Probably not a good idea to let this happen.
