S25 ultra size adaptation

I came from a 6.7' M51 but unfortunately was not able to adapt to the s25 ultra 6.9', I've been suffering with hand and arm cramps in the last 5 days of use, so I finally decided to return it and buy an S25+. I'm really sad to have to give up the Spen which would come really handy for my paper readings and to give up the incredible camera on this phone. Anyone that has been using the phone and suffered from those cramps know if it passes? I have two days keft to decide if I will return it or not, would love some advice.
