Have you been to a Samsung service centre? The team in Wellington are super helpful and will always try to fix any and all issues before sending your device away for repair or recommending an upgrade.
One way you can extend your device's life is to run diagnostic checks - and while the service centre staff are more than happy to help, this is one you can do yourself!
From the Members app, select "Support" from the options across the bottom of the screen, and tap "Phone Diagnostics". You can do individual tests, or test all!
My S22 Ultra has 25 checks, including buttons, speakers, cameras and the S Pen. My Watch5 has 15 checks, including wrist detection, vibration, and notifications.
Ideally you should restart your devices once a week, so be sure to do a diagnostic check regularly too.
