Review: Is good - 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.
Review: Awesome - Product in the condition described. Still setting it up, but everything seems to work. I'm happy with the purchase so far. The S21 Ultra itself is a fantastic phone: speedy operation, bright screen, long battery life, superlative camera with 10X optical zoom and lots of pro features (or just use as a point and shoot camera). I love being able to use the volume button as a shutter release for the camera. It's also great that you can re-program the Bixby button. I chose for the Bixby button to do the following: short press - lock screen; long press - power down; quick double-press - open my favorite app. I'm looking forward to discovering more. Checking for available updates allowed the phone to be updated to Android 14 and to Samsung One UI version 6.1.

### ⭐ Not Worth the Money or Time
*by L***W on May 5, 2025*

I purchased a Samsung S21 Ultra that was described to be in "excellent condition" for almost $300. It was shipped via FedEx and I received it as scheduled. I opened it the following night and noticed more scratches than I expected, also it had a charge of 14%. I immediately placed it on the provided charger and a message popped up stating to "check the charger connection", I noticed it seemed to not fit snuggly into the port. I tried a couple other chargers, and it was the same. I reconnected the provided one and it begin charging slowly again. The next morning it was at 100% as soon as I removed it the percentage dropped to 99%. I went online switched my phone service and went to work, I noticed around 10a it was already at 65% without any usage. By 2p I had charged it twice and had only made 2 quick phone calls and sent a couple of text the entire day, had this been a normal day I would have been stuck using my business cell. I resorted to wireless charging the remainder of the day. I haven't been able to use it as I typically would, but it seems to be what I would expect a high phone quality from Samsung. The 2 pictures I snapped were nice. Also, I haven't had a Samsung in a few years but I love the many updated functions provided, also thankfully it was actually unlocked so I could use it with TMobile. I contacted the seller about the stated issues and only received a question asking if I tried another charger. I responded several and stated I can only wireless charge. I requested a full refund because this phone is defective. I haven't received a response but will be returning it this week. I was very disappointed with my purchase and would NOT purchase from this company or refer anyone to in the future.
