Battery is _TERRIBLE_

Reviewed in the United States on November 14, 2023

I knew going into this what to expect, but i would have thought considering how much they cost, they would have done something about the battery, as someone who doesn't know the 30-80% rule could easily destroy a decent battery, very quickly

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.

Graduation Gift

I got this as a graduation gift back I'm 2022, and it really has been a great phone. It was only midly scuffed and worked like new. I still have this phone in 2024, and I will only need to upgrade if I want some new feature, otherwise this will last me many more years to come. It also seems to be considerably cheaper and perform better than newer phones with just a few less specs.

She LOVES her new phone!!

Hi! Nicki_Blaze.711’s friend here 👋🏻 Got this as a gift as a surprise for her and she’s absolutely loving it. She’s been off socia media for a while and I wanted to inspire her to get back to what she loves and I believe it’s working! She’s been testing it out all week and says it works just like new and has zero wear or tear on it. It does overheat sometimes but that’s with her usually either gaming on it all day and night for her social media WHILE live-streaming or chatting on discord at the same time AND screen recording her gaming for video future content. It’s able to handle all her Likee, Mico, and Tiktok needs! How she does it all I have no clue lol. She says it charges super fast and can handle a lot, so if you’re interested in grabbing this phone for yourself definitely go for it. She hasn’t tested the camera out on her cosplay and makeup looks just yet but she said the camera features are amazing and are going to take her content to the next level. Super excited to see her start posting again. A special thanks to the seller on sending it to me so quickly👍🏻

It's still the best phone you can get IMO

Reviewed in the United States on September 22, 2023

Size: 512GBColor: Phantom BlackService Provider: UnlockedProduct grade: RenewedVerified Purchase

This phone is kinda like a jack of all trades. Maybe when the S24 or 25 comes out, I'll get the Exynos variant, just because they spent more time developing the newest chip, it's actually made by Samsung and I heard they're easier to root. It used to be easy to root Samsung phones but now it's next to impossible and temporary if you do, before they update it.

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.

Make the switch and upgrade - its so worth it!

The phone is in excellent condition as offered. I was pleasantly surprised with the quality and very please with the condition. A little wear and tear around the camera area where a case had been and a light cosmetic tiny scratch on the front glass. In all, I'm very happy with my purchase. The quality of the phone is amazing and I only wish I bought new when I had the opportunity. This is an S21 Ultra 5G with 512gb and 16Gb of ram. There's some confusion as to whether you'll get a 12gb or 16gb. This was a 16gb version. The Samsung Switch app can be used to move your old phone over to the new phone (apps, data, email, etc...) Both phones have to have full charges to work properly.
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.

Very very good phone, except came with cheap SLOW charger

Reviewed in the United States on April 27, 2024

Size: 512GBColor: Phantom BlackService Provider: UnlockedProduct grade: RenewedVerified Purchase

Very very good condition for a used phone, except came with (brand new) cheap SLOW charger. As expected per many reviews,this Samsung model phone is indeed rather heavy leading to hand-cramps for long calls / long use periods, but that's not Seller's fault. Based on a few comparisons I saw on-line, the phone that arrived was NOT a counterfeit, which is good -- it was my biggest worry. There are counterfeits out there are VERY hard to discern from the real bonafide Samsungs (so do homework before buying) and beware of sketchy sellers too. Bottom line: I am satisfied with my renewed phone from GENIUS GOODZ.

Rated Excellent, not even close.

This is the second device I ordered from these folks. The first one was flawless, this one, however, was in good condition, but far from excellent as was advertised. It'll suit my needs, as it was bought for a back up device, but it'll be wearing a case, so all the scratches and dings won't show. The screen is almost perfect.
