This was well worth the investment. I use Google Fi and upon starting the phone after inserting the sim card, the phone switch over immediately and I was rocking 5g.
This was a fantastic purchase! Thank you.
This phone is one of like 3 phones that has stylus support, a curved screen and 120hz. I wish the thing had a 1TB option or Micro SD Card support but everyone loves to copy Apple for some reason, even after making fun of them/boasting about features their phones still have. Just like with the headphone jack.
I'm personally into buying or building products/devices with the least amount of brands/manufacturers, so the fact that this phone is pretty much entirely made by Samsung this year, even the Qualcomm chips, is pretty cool. I feel like GoodLock is getting more and more stuff added, for personal customization, though I wish they'd stop changing the way you can screenshot, so I don't have to keep finding workarounds. Even though there are some things they tried to take away, this phone still allows more customization than any other phone, maybe except Xiaomi. Xiaomi allows you to customize the boot logo/animation without root!
eSIM WILL NOT work for Verizon or any of Verizon's MVNOs which is absolutely ridiculous. It's sucks enough that you can only store 2, only 1 can be used in junction with the regular SIM and that's fine but why does any eSIMs beyond 2 get deleted? Who knows...
These speakers are loud and the Snapdragon 888 is still a great option for emulation or Android games. It doesn't get too hot and the battery can last you quite a while, even for a heavy user like Me, who downloads a million apps and keeps quite a few things in the background. It's still snappy and works as it should. The cameras are decent, probably not as good as My Pixel 5, but it's close.
The charging speed, I'm used to it now but 25w? Come on... even older phones had at least 45w, but I guess Sammy was afraid more phones would go boom boom. At it's fastest rate, it will charge from around 5-10% to 100% in a little over an hour. I do love that there are so many options for accessories, since Samsung's phones are such a global phenomenon.
I didn't pay much to get this phone refurbed and I just don't personally think it can be beat. The sides had a bunch of micro scratches that I just covered with a clear case, which had a Black frame, that I put on top of a skin. For the money I paid, it's nice to have a curved 120Hz 1440p LTPO screen with a ultrasonic fingerprint reader (even though it's a bit slower than it should be) and stylus support, 512GB of storage, 16GB of RAM, a Snapdragon 888, DeX/HDMI Out, a 5000mAh battery, wireless charging, reverse wireless charging (even though it's super slow), a front facing camera in the middle of the screen at the top (though it'd be nice if this was under the display or just didn't exist), IP67 or 8 water resistance, extremely loud speakers, eSIM, the latest One UI + Android Security Patches until 2024 I believe, etc.
I have a lot to say about this phone but overall, if you can find it for $700 or less, its a great phone and probably the last one that will be this curvy and feature packed.
Well ok, here's the secret guys: keep your battery between 30%-80%, only charge when at 30 and only charge to around 80%. If you discharge the battery fully, recharge the battery fully, but only that one time and do not charge above 80% for any reason, and you'll very quickly train your battery, not to mention have it last a very long time.
Otherwise, the performance is great, but the battery is _terrible_ you'd do well to go ahead and have it replaced for a new one, fyi.
