Message App

I am so disappointed with my brand new S25 Ultra. Couldn't transfer my WhatsApp chatts from my S22. I visited Samsung maintenance at Mall of the Emirate 3 times, they couldn't do anything. The phone battery drains within 4 hours of normal use. Please send me your opinion? I am ready to pay a difference for a better new phone. My phone is 3 weeks old only and I am fed up with it .

Hi Eeue, just open the Samsung messages app and it should ask to be the default messaging app, and you're good.
Try searching for the app using the search bar at the top of the apps drawer. If it doesn't show up, you will need to download either from the Galaxy app store or Google Play store.
