### ⭐⭐⭐⭐⭐ It's a great phone
*by Q***Y on February 16, 2026*

I love the phone. I've been using it for over a year now, and it works perfectly

### ⭐⭐⭐⭐⭐ Like New condition
*by M***D on February 21, 2026*

### ⭐⭐⭐⭐⭐ Is good
*by R***Y on September 1, 2025*

Ok, so here's my initial review, it may change later but for now here it is. Recieved the phone yesterday,it was very well packed. Came with charger block cord and ejection pin. The phone literally looked brand new, if it were in a samsung box I would have thought it had never been used. I transferred all my data and apps ( and after about 5 years that took about 2 hrs...lol). Then I put my T-Mobile sim card in it and restarted and no problems. Updated the phone. Everything was fine. IMPORTANT: be aware that when transferring from old phone to the new one or charging the batteries the phone will get warm..this is natural. I let the phone charge over night and did a battery usage test..after 3 and 16 minutes hours of continuous use watching videos , playing games , texting and listening to music it had used 44% battery so use that information as a guide, since it was continuous i don't feel that's too bad. Picture quality is good, sound is as well. So as of now I'm happy. If that changes I'll update.
