Frequently asked questions

A 'Renewed' Samsung Galaxy S21 5G is a pre-owned device that has been refurbished and inspected to work and look like new. It should come with limited or no wear, and its performance is tested to meet factory standards. Renewed products typically come with a warranty, but this can vary by seller.

The US Version of the Samsung Galaxy S21 5G is designed to be compatible with US carriers and may not support all network bands used by international carriers. It's important to check with your carrier for compatibility before using it internationally.

An 'Unlocked' Samsung Galaxy S21 5G means that it isn't tied to any specific carrier and can be used with any GSM or CDMA network that supports its wireless bands. This provides flexibility to switch carriers or use local SIM cards while traveling abroad.

The 256GB storage option provides ample space for apps, photos, videos, and other content, which can help maintain the device's performance by preventing storage-related slowdowns. However, it has no direct impact on the processing speed or graphics performance of the phone.

    • Not as promised! Battery drainage and hot phone. Advertised as Excellent but very poor quality.

Packing was good it was bubble wrapped nicely but I wouldn't put this as "Excellent" since there is many small scratches all over the screen and frame. Also my biggest issue is that it came completely dead and wouldn't turn on so I charged it and it charged fast but it dropped from 40% battery to 15% in 15 min! Unacceptable. I hope the seller will resolve this without charging a restocking fee since this should be on the accountability of the Seller selling a poor product and not matching the description as excellent. See the attached photos to show the time stamps of battery drainage. Also the phone is insanely hot and burning my face when I tried to have a 2 min conversation on the phone. ... show more

    • Good value for the Money
OK, so I must admit this was my third phone through amazon renewed, the first 2 were questionable when it came to excellent condition. Trust me, they had various issues too numerous to explain. This 3rd phone though is excellent so far. Condition, I would say is practically new. Case and Screen were blemish free, not even signs of fingerprints. The phone is Verizon branded, but does not impact phone service or use. It is unlocked and work with my Tracfone sim through T-Mobile. Testing battery life, but it seems close to normal after a few years of use. Used it all day and I still had 25% battery remaining with really heavy use. Data transfer went flawlessly with no hick ups, very easy and straight forward. Even the sim was immediately recognized without having to call the carrier. Everything seems to be in good working order. The person who owned this phone 1st really took care of it, you can tell. Other than the branding issue on start up and a notification telling me my sim is not a Verizon sim, everything seems to be in good working order. This is an upgrade for me coming from am Galaxy A20s. The upgrade was immediately noticed. And 256gb memory is just enough for me. I carry books, music and movies in my phone and this has handled everything I have thrown at it without issue. The camera is great and takes amazing photos compared to my last phone. Buying through Amazon renewed is a crap shoot really, it depends on the last user(s) and what may have happened to the phone, I can imagine the phone's people are turning in. I'm sure most have issue from over use and drops, to phone malfunctions in general. And from studying the vendors who sell the phones you really have no idea what they might do with them once they are rehabbed, Water damage, electronic issues, even screen replacements. All the phone are going through private phone companies who refurb them and send them back out. Like I said, 3rd times the charm and I lucked up on what I think is an excellent buy. Would I do again, sure, but make sure to check out the phone thoroughly during your 90-day return window. I will continue to test out and report back if any issues popped up. But so far so good. Check the vendor rating and issues reported in reviews. Typically, they spell out possible issues with phones or vendors selling them. I have always believed in recycling items, especially electronics. So do your part and make sure they don't end up in landfill somewhere. I have liked Samsung products for years and this still holds true with this phone. I don't need the latest and greatest, but I know I have a few years still before a newer model takes it's place. Furthermore, I usually hold on to a phone for 2–3 yrs, depends on the phone. Oh yeah, 5G is the hits. Very smooth and fast, no delays when surfing the web, everything just flows like a hardwired home system. 120 mhz is smooth and haven't noticed any hang-ups. Yes, I would buy again through Amazon renewed. But I'm sure you could find the same product locally at your local phone store. I'm happy with purchase and would recommend with caveats. Check your phone carefully, run it through is paces and test everything, camera, sound, display and any function you think is important and even those you might not think is important. test all settings and make sure all your setting take effect. This phone is loaded with options and it took about 3 hrs to transfer and update this phone once I started things up. Gaming is great, and the display is amazing. No glitches during game play. It's almost to fast that I can't keep up visually. So two thumbs up on buy. Finally moving like most with an upgraded phone. ... show more

    • Definitely what I was hoping for
I am always leery about buying used electronics. You never know if you get the one that was barely used, and the person is just a serial upgrader every time a new model comes out. OR, if the item was traded in because it was malfunctioning, and wasn't spotted before being resold. Not the issue here so far. Tested every feature that I would actually use and it runs smoothly and quickly. From a full charge in the morning before I go to work, and with moderate usage throughout the day, it is generally down to about 80% by the time I go to bed (usually between 1:30 and 2:00am). I am upgrading from a much earlier model Galaxy and the camera (both still and video) quality is spectacular comparatively. Particularly in low light. Verizon SIM card transferred over without issues and that Samsung transfer app was a God send for getting all of my stuff (including pix, wifi passes, etc.....) over to the new phone. The lack of an SD slot makes me a bit nervous, but this one is the 256 gig model so hopefully, I won't have to do much relocating of files, images and videos over to my PC with the space that there is on here. Physically, the phone was in pretty good shape. Though there were a few minor scuffs on the back, the glass for the screen AND the camera lenses were flawless. And, I always use a case/holster anyway, way back since the old flip phone days. So, I will never actually SEE the body of the phone anyway. All in all, up to this point, I feel like the investment was good. There is 90 days worth of warranty so if I stumble across something that is a deal breaker, I can return it. If you are looking for a phone that won't cost as much as a cheap automobile, this "renewed" option may be something you can look in to. I will be trying it again when it is time to make another upgrade. ... show more

    • Huge upgrade from my previous phone
I used to have a Galaxy S8 active until I sadly drowned it on accident, I set out to find a goof quality phone that wouldn't break the bank, and this was spot on. It has a great camera quality, and even has the ability to take .5 photos which I was always jealous of other people for being able to do, it's sleek with all the cameras to one side which gives plenty of space to hold or grab the phone at. I haven't noticed it running too hot unless it's an abnormally hot day, or running a very processor heavy app or program. The phone came in great condition, with only some very minor cosmetic damages on the back of the phone, but all functuons worked great, and none of the screens or cameras were cracked. All visible damage is covered by any case I've used. The battery life is pretty good, of course you can stretch it or run it faster depending on what apps you're using, I am usually able to get through a whole day at work starting at 6:30, and ending at 4, without needing to charge it, of course if I am watching videos or playing music, the battery will be used a bit more than if it's just locked not doing anything. ... show more

    • Little Disappointed
This phone is a powerhouse. Overall this phone is good, but it does have some areas of concern.. I will explain why by reviewing the good and bad features of this phone. Let's start with the good features. This phone has a vibrant screen and has a great camera. The touch screen is responsive. I do like the fact it identifies likely scam callers. Now I need to figure out how to tell the phone to automatically ignore likely scam callers. The eye comfort setting is nice and easy on the eyes in my room at night. The 256 internal storage makes up for the lack of internal storage. This has many ways of identifying you by using a pin, figure print, and or face recognition. These are strong pluses for the phone. There are features that I like, but some of the basics can improve. It is missing a headphone jack so good luck finding an adaptor that allows you to talk on a headset and charge your phone at the same time. It takes a few attempts to unlock my phone using my figure print. The battery drains really fast, and I leave my phone on the charger most of the day. One time while at the gym, the volume level was constantly changing when I was at the gym using my headphones to listen to music and playing a game. The headphones would be blasting and hurting my ears, and after adjusting the volume, it would either go up again or go down to a whisper. I wonder why the phone gets hot near the camera area. Getting hot for no reason is not a good sign of reliability. Hope this phone lasts. It took me a while to find a good switch that allows me to charge the phone and talk in a zoom meeting. I Hope Samsung releases a fix that addresses the erratic volume and getting hot for no reason. I really like the responsiveness of the phone hope this phone is a good investment. ... show more
