I paid a few bucks more to purchase from Chubbiestech based on a review and to avoid any problems. (Reading about the A10 reviews was scaring me until I realized I was reading the wrong product lol.) This is for the Samsung Galaxy S10e. Being from the S- product line, it's Samsung's flagship product and you can read the history and differences between the models on Wikipedia. I found this information very helpful.I lucked out with the right Seller and got a phone that really seems brand new and works excellent in every way. (A previous purchase of a different model and seller was excellent in every way but then we discovered it wouldn't charge.) I'm so happy I bought this!ProsMine was in new condition without a scratch, and functions perfectly in every way. I was able to load SmartSwitch on my old J7 and only had to manually download a matching icon set (and create a new Samsung account to download it.) Everything else (including my custom wallpaper from an outside source) transferred exactly.I wanted a smaller profile/screen because I really loved my J7 and can easily operate it with one hard. I find modern phones too large and heavy and I'm not a gamer. The S10e's profile is surprisingly *smaller* than the J- series and fit my desire. Could easily fit inside a shirt pocket.It runs way faster than my old phone and I verified with DevCheck that it does indeed have 6 Gigs of Ram. That's more than I ever had before and so it seems real speedy and capable to me and also 128 Gigs of space is way more than I ever thought of using.I mostly only use my phone as a music source and the sound quality thru my headphones is superb, like my J7 which I prefer to the modern soundboards that I have to tweak; I don't have to use the equalizer on this and the bass is great.The Wi-Fi, Bluetooth, screentouch and call quality (and charging) all work great. The mobile data connection on my old sim for some reason is much faster (30M??) on 4GLTE and the upload speed is 3x my old phone too, I can't imagine why. But the connection with the same service is just stronger and has much better coverage. I didn't realize it was the old phone limiting it. That's like broadband over 4G lol.I simply slipped in my old Sim and it connected with no problem or troubleshooting.Anyway the S- series hardware of this phone is superb. Mine came with Android 12 which I understand is the highest available for this model. My J7 was stuck in Android 8. I didn't want to upgrade to a phablet nor pay a lot for features I didn't want to begin with.Caveats/TipsI never used a case before but this phone is so small (yay!) AND slippery I needed to buy a case. Don't want to drop it and scratch the screen because my big clumsy fingers can't hold onto it. I don't have a problem navigating the screensize.Had to manually customize icons after installing everything. This requires a Samsung account. (You can delete it from Accounts afterward if you wish.)If you use Smart Switch to transfer and duplicate your experience from your old phone you need to unpair the devices listed under Bluetooth and re-pair them for them to work on your new phone.Many/Most of your programs transferred and websites will require you to log-in again (so you'll need your passwords) but the data (pics/docs/program files) transferred without a hitch. (You can download Smart Switch on your old phone from Google Play.)My phone has the annoying T-mobile start-up screen (less annoying if you turn the sound off) but it doesn't harm anything functionally.Samsung apps preinstalled cannot be uninstalled or disabled. However Google apps can be.The battery is small (3100) but I'm used to that from the J7. I tried a larger capacity battery in my J7 but became impatient with the charging time so actually prefer the quick charging of these.This review is obviously for folks who may not have done this before or are doubtful about the quality of the renewed product.I'm totally happy with the new phone and the process of setting it up was seamless. Definitely worth it and you saved a lot of money! (Now you can peruse the internet and modern apps like the Joneses! :)Update: It's a bit too small to be honest, and very SLIPPERY, however still prefer this to the large ones. Wish they still made J-size. But everything works great, sounds great and I'm getting 50M download on LTE! All I do is listen to music so it's fine for my needs. Great price for a fast phone.
