It's been brilliant so far. Everything has transferred across from my previous phone. I'm really pleased with this 'new' phone.

Perfect for my needs. I loved the S20FE for its functionality and versatility in terms of SD card slot and battery life, and didn't want the newest phone so I opted for the "upgrade" and the S20 Ultra is faultless to a T. I especially love how the resolution is crystal clear and the 12GB ram!? I am a heavy user and this phone is perfect.

I've sent my old phone back but you keep requesting that I send it back. New phone's camera doesn't focus in 1x or 2x. looking forward to getting paid for my old phone.
