Survived the river!
on August 17, 2021

I just recently bought my phone, about a month and a half ago. Had to tell my story that could have easily ended in disaster!!
Day 3 on the river! Started good. First dunk in the river because I had to test my skills standing on my kayak. Did it the second time! Second "dip" was an unfortunate turn of events. Tried to adjust. My ball cap. Sunglasses (prescription) went in the water. Leaned over to grab them and kayak flipped. I did get the sunglasses! Good thing Gerry was right next to me. Got the boat flipped over, full of water. All my crap floating down river towards the others. Phone at the bottom of thigh deep water, nowhere to be seen. Got the boat to the rivers edge before it sunk. Then I'm frantically walking up river in the stinking deep water trying to find my phone. Gerry yelling at me to just let it go. You're not going to find it. Gary comes up river to help. And lo and behold finds my phone. Get back to shore and my phone is up and running! We couldn't believe it. Still had a ways to go, but all was good in the end. Let's just say, memorable.
I would recommend this to a friend!

Overheats
on August 27, 2021
Posted by: Luv galaxy

This phone gets way too hot way too fast. I have had samsung devices for over 10 years now. I was really excited to upgrade to this device, however, when I got it and started using it, total disappointment. I find the camera quality is not as great as compared to the s21 which I had b4 I got this ultra. The phone overheats and can't be held in hands for a long time. It has gotten so hot from the time I started doing this review. All my sisters and I got this phone and we all are experiencing this. I would not recommend this phone. I would say keep s21 if you don't mind a smaller phone. I worry that this phone may overheat and catch fire like the note 7 did.
No, I would not recommend this to a friend.

Missing Notes
on August 27, 2021

Expertise:Beginner
It's been less than a month with the S21 Ultra 5G. Still getting acquainted after parting with my galaxy s8. I cannot find my Samsung Secure Notes that should have crossed from the S8. This is highly upsetting for me. ARE MY S8 SECURE NOTES HIDDEN SOMEWHERE ELSE ON THE S21 ULTRA 5G? PLEASE, I NEED HELP!!!!!

Great camera...worthless without micro sd card.

Expertise:Intermediate
This phone has a wonderful camera, but without a micro sd card, it's worthless. I use the cloud for BACKUP, not for my primary storage. I like having my music and photos local...it's just faster and I can access MY things from MY phone even when I'm not connected (remote areas where I often travel). Later Samsung. I won't be upgrading this go around.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] Overall it's a good phone. Runs fast. Samsung interface is different than google pixel's and takes some adjustment but camera quality is great and just takes getting used to.
I would recommend this to a friend!
