My phone is hot to the touch period after installing this beta update. Also my phone was hot to the touch after I recorded a short video the other day. I have had the S22 for not even 2 months. So far I am extremely disappointed. Thinking about jump over to the pixel 7.
Wireless charging and recording at high resolution are both well known to cause heating. The xperia phones are notorious for shutting down after 10 minutes of 4k recording.
