S25 Ultra

So far my S-Pen stopped working and my network has been lagging since installing the UI 8.5 with apps like Tik Tok and Facebook but other apps are working just fine. I absolutely love the new look 😍

Just tested and my s-pen is working fine.... haven't had any issues on 8.5. Network has been good also. Maybe try clearing cache in recovery. I always do after a big update.

Thanks for the information Chaz, I removed the pen then restarted my phone and that helped reconnect the pen

Unistall than reinstall apps, I haven't had a problem with my Spen and have you tried clearing the cache partition after the beta update

[Almalik]

Thanks for the information that very helpful 😊

I've had to reinstall one app, Robinhood, that didn't work but I wipe cache 3 times....old habit.

Clearing the cache did it for me thanks 😊

Thanks for the feedback, I removed the pen then wiped cache. I kept the pen out until restart was completed so now all is well

Are you using a magnetic pop socket? That's been shown to interfere with the s-pen operation. It could be your case/pop socket and not necessarily the software update.
