this far, this device is working great. My only 'issue' was transferring data from my Pixel to this S25 Ultra. I installed the Samsung app on both phones and the app did transfer the 'service' to the Samsung but I ended up manually installing all the apps. Tedious process but it's done and the Samsung is much quicker and the battery life is much longer. 2 things I've noticed over the last few days.

The Phone is great, in perfect condition and works as if I bought it new - and I get a 30 day return option and 1 year warranty included! I love Back Market. I also bought my Mac laptop 6 years ago from Back Market and I still love it and it works perfectly to this day,

This is my 4th phone that I've purchased from back market. Previously purchased phones for my grandson and a work phone. This phone is an upgrade from my original phone. Received it quickly and arrived in excellent shape. Now I have to figure out how to use it, I had a Note 8 before and updated to 25 Ultra.
