    • The phone works perfectly, and I'm returning it
The bottom line on the product itself is that it works just fine. It was in "new" condition. Everything worked as it should. It took a while, but it automatically updated itself to Android 15 and One UI 7.0. But I'm returning it. Why? Because I'm 158 years old and I don't like many of the changes they've implemented. They've moved the volume buttons from the left to the right side. They've combined the bixby with the side key (the unlock key). Don't know what this has accomplished. Google assistant (with the gemini conversion) now requires you to tap the mic icon rather than just listening to you automatically. There's a new (to me) feature called Circle to Search which is a bit annoying. You can disable it, but that completely disables the home button (and google assistant). The video of my beloved dog that was on my lock screen doesn't work and this is a reported issue. The battery charge indicator on the top of the screen is now superimposed over a partial battery icon, making it difficult to read. (Excuse me for not having 15-year-old eyes.) A couple of my favorite apps no longer work. There are several apps that I haven't yet tried and I have to wonder how many will work. Due to all this, I've decided to return this phone and pay someone to replace the battery on my old one. ... show more

    • Great deal! Great phone!
My phone arrived looking PERFECT. It looks brand new externally without a visual blemish on it staying true to the EXCELLENT condition standard. Setup was rather smooth. The only hiccup I encountered was that the phone didn't recognize my Mint Mobile SIM card for some reason. Looking for an answer, I found that I could use an eSIM setup to get around that which got my service on the new device. I'm not sure why the phone didn't recognize the SIM. The phone appears to be working fine so far. If anything drastically changes I'll update this review. ... show more

    • Absolute JUNK!! BUYERS BEWARE
I bought this in October 2023. I got it, turned it on and did the setup. I turned it off and put it in my safe. Today is April 8th 2024. I took my phone out of the safe and turned it on. It loaded the main screen of the phone and then the screen went bright white.. You couldn't see ANYTHING!! Ive tried everything to get this phone working. The cellular gallery Inc is who the phone came from. They flat out refuse to do ANYTHING to replace the $290 I paid for the phone. I have fought for weeks with Amazon and this company. I googled this company and there are THOUSANDS of reviews that this company sells junk broke down phones that don't work past 90 days. I never thought about my return deadline date since the phone worked at arrival and it was in my safe untouched since October 2023. These people sold me a POS phone and neither them nor Amazon want to make it right. DO NOT BUY FROM THESE PEOPLE. YOU WILL REGRET IT!! Take your money and go to eBay!! Atleast if you get something off there that is below customer satisfaction eBay steps in and does the refund themselves.. Amazon holds no accountability or responsibility when it comes to ANYTHING that is sold by ANYONE but themselves.. So make sure you do a complete Google search for the buyer before you purchase ANYTHING off Amazon.. ... show more

    • Excellent condition, unlocked, worked with a European SIM card
I needed an unlocked phone to use in Italy and Austria. I bought this S21+ along with an "Orange Holiday Europe" SIM card. The phone arrived in excellent condition, with no scratches or dents. The screen appeared to have been replaced. After setting it up, I tested it by installing SIM cards from AT&T and TELLO, both worked perfectly - it's definitely unlocked. Right before the trip, I installed the "Orange" SIM card with the phone powered down. Upon arrival in Italy I powered it up, and it immediately connected to the local service. We used Google Maps to get from the airport to our hotel some 50km's away, no problems at all. Photos taken on the trip were excellent. We installed Google Translate and Microsoft Translator which worked perfectly and were a real asset in helping us navigate the foreign signs, menus, etc. We also set up Hot Spot and Tethering, and used that along with wireless calling on our US SIM based phones to make and receive free calls and texts to/from US numbers. It all worked as expected with no issues. There are two minor issues to report. The battery life was OK, I would start each day at 100% but by end of day it typically had around 30% remaining. My new (locked) S23+ easily gets two days on a single charge. I did notice a minor blemish on the screen after a week of using it. At first I thought it was just a greasy smear, but no amount of cleaning has managed to remove it. I didn't notice this when I first received the phone so it most likely manifested after use. It would seem to be a flaw with the screen itself. I did not use a screen protector, which may or may not have helped to prevent it from occurring. Fortunately it's close to the bottom of the screen and has not really affected the viewing area, nor has it affected the touch screen in the area of the blemish. All-in-all I am happy with this phone. I plan to use it for future international trips as it can do what I need without having to pay the $10-a-day AT&T International Roaming plan - that soon gets very expensive with 2 or more phones. ... show more

The phone works fine but it came with an old Apple cable that I can't use and the battery was totally empty.

    • As always, galaxy is superior
My galaxy S 21 finally broke (sim slot, Charging port and the battery was shot)after several years and I ordered a knock off samsung 25. It may have been brand new, but it was horrible in every aspect. I ordered to replace it with basically the model I had before. The only gripe I have is the back is kind of separating on one side and I ordered the "excellent" option. I'd much rather have a galaxy that's a few years old and refurbished, than a brand new, well, anything else that isn't samsung. Everything works seamlessly and data transfer was a breeze from my previous galaxy. Shipping was quick, it came charged and unlocked for mint as stated, unlike the phone I just sent back. I'm not sure how I can attest to the battery life yet as I've only used it since this afternoon. ... show more

    • Great phone, but can't update
Review Image by LovelyLady
So I purchased this phone in 2022. Don't get me wrong I love this phone and it is still in great condition, not a scratch or crack in sight. The only thing is, I don't get updates. I cannot update my phone. I am probably like 3 1/2 years behind in updates. When I try to update my phone it's says "Your current software version isn't supported. Visit a service center" The last update was October 22, 2021. Like I mentioned the phone is in great condition but I think updates are necessary to receive full functionality of the phone. I don't know what the previous carrier was so I believe that's preventing me from receiving updates. Even the phone is unlocked it is still locked to previous carrier. I will not be purchasing an unlocked phone ever again. ... show more
