Good phone

4 years ago
After having my S9 for a little over 3 years and enjoying a low phone bill because all the phones were paid off we decided it was time to stop dealing with broken fingerprint sensors, weak charging ports and cracked screens. The S21+5G has been awesome so far. it feels and looks nice, the cameras are great, and lots of features my wife and I are still figuring out about. The ultra fast charging is a plus. The ONLY downside was that it does use the new-new C type charger and does not come with a charging box that plugs into the wall. We found some at wal-mart for 15$ though. I highly recommend this phone!

Firmware/Software issues plague devices

4 years ago
The phone is great. It feels good in the hand, it takes great pictures, it's fast and the battery life last all day with medium usage. However; had to return the device. Due to a firmware issues on the S21 series, some devices have issues with cellular data not working when trying to download apps from the Play Store and some Google apps not working (YouTube for example). I was told that there would be a software update that would fix it, but ffter spending days on the phone with T-Mobile and Samsung, they told it this was a known issue, and offered to replace the device with a refurbished unit. I decided to return it for a refund instead of accepting a refurbished unit.

It's not my favorite

4 years ago
I broke my previous s9 and went for the s21... I was sad that I had to get another phone but looked at a few and thought this one seemed nice. But I have quickly learned there are some things I hate. The front camera is placed differently. It's just a dark hole in the middle at the top. Gonna take some getting use to. The charger is doubled sided, not the USB port then the charging side. There is no place for headphones or an aux cord so you'll have to get wireless headphones if you haven't already. And any car you get into has to have Bluetooth capabilities because otherwise, no streaming for you. Those are just some things I've noticed so far. Only have had it for a day.

Yes, I recommend this product.

Change it back!

4 years ago
[This review was collected as part of a promotion.] I'm NOT a fan of the new phones. The biometric NEVER works, unlike my old phone that swiped in the back and gave me zero issues. The lack of SD card is a sham. They couldn't even transfer all my files to the "new" phone because there wasn't enough storage! The screen is AWFUL, forget trying to look at it in sunlight. You can't see anything! Really?! Y'all can't figure out how to make it readable in bright sunlight? The battery is also crap because you have to constantly turn up brightness to try to read it. The ONLY positive is the decent camera and the Android operating system. If it wasn't one of the few androids, I wouldn't have bought it!

No, I do not recommend this product.

Great everything!!!!

4 years ago
[This review was collected as part of a promotion.] I have had this phone about a month now and am loving everything about it. I got my husband and son to switch to it as well. Son was a diehard apple fan so this was a big step for him. He is loving it and glad he switched as well. The camera is amazing and we just returned from a two week road trip through Tennesse and the Smokey Mountains. The photos I captured with this phone rival anything I have ever take with my professional 35mm. The speaker phone is very clear and people comment and ask if something is different as I sound better and I get to share that I got a new phone and I they should get this phone too. I LOVE THIS PHONE!!

Yes, I recommend this product.

Awesome Phone

Gave it 4 stars because the phone and the camera work absolutely amazing! Biggest draw back for me is the loss of adding additional storage.

Yes, I recommend this product.

Top of the line!

4 years ago
[This review was collected as part of a promotion.] This S21+ was my upgrade from the Samsung Galaxy S8, and man, what an upgrade it was! The processing power of this thing is mind blowing, I can't slow this thing down! And between grueling days of personal and business use, I come home and still have battery!? Amazing. Pictures are clear, and the options to edit without additional apps is pretty robust (I think.) The features are insane, from their samsung pass and security integrations, to Dex and linking windows. The only "downside" is how ENORMOUS the screen is.... but you quickly forget about that with two apps being shared split screen and a third in pop-up view ;)

Yes, I recommend this product.

Change is never easy

4 years ago
[This review was collected as part of a promotion.] The phone was a replacement for my Note 9 that I thoroughly loved. I miss my stylus the most. Generally change is more a bump in the road than a mountain to be climbed except where technology is concerned. I get frustrated when basics get changed for no apparent reason. Due to battery problems with the old phone, very little of my old stuff was able to be transported. Sure, apps were copied, but none of the history that went with them. Not Samsung's fault, but frustrating nonetheless. Why change the way to open the phone? I mostly play games and read books on my phone, so I'm not terribly interested in new stuff. Just don't care.

Does Everything Extremely Well

4 years ago
[This review was collected as part of a promotion.] I've had my S21+ for 1 month now and absolutely nothing has disappointed so far. Everything is relative, as the entire cell phone landscape has improved so much since back when I got my S9. But with that in mind, the S21+ still impresses. The little things like fingerprint scanner and facial recognition are handled perfectly with this phone. Everyone expects great cameras in phones now, and most phones deliver. The camera here is managed very well and the shots in low light are extremely good, and video has equal results. If you're considering this phone you can't go wrong, and you will be glad you got it once you use it.

Yes, I recommend this product.

Great phone!

2 years ago
[This review was collected as part of a promotion.] This phone is one of the best phones I have ever had. Previously I used lower level or cheap phones that worked but lacked so many of the awesome features found with higher end Samsung Galaxy phones. I love the ability to submit error reports to Samsung and absolutely appreciate they respond and care about the customer's experience with their devices. I love the biometric sign in and phone unlock. Its fast and makes it less of a hassle to keep your phone locked. I also love the screen picture quality as it far exceeds anything I had previously. Samsung also provides updates for your higher end devices for years! They're great, give their phones a try.

Yes, I recommend this product.
