Top reviews from the United States
There was a problem filtering reviews right now. Please try again later.
I had to order another B20 due to the charger port came out in less than 5 weeks.
Pros
I see the price has dropped down dramatically for this B20 phone and I see why (see Cons).
Cons
1. You can't have get any parts for this B20 phone to be replaced for any work or replacement on it. NUU is the only place you can get it repaired at and it has to be shipped back to them for any repair.
2. The B20 doesn't support wireless charging pads (I had a bad charger port that fell out).
3. Now the camera on the B20 sometimes has the problem of switching back from the front camera (selfie) to the rear camera for apps like Google Meet, Marco Polo, etc...., it kept getting "stuck" on the rear camera. I had to cut the phone off for 20 minutes and cut it back on for front camera to comeback.
Older comments
It took a few days to resolve issues I had. I bought this as a gift. I'm still accessing the phone.
Pros
1. Bigger than the free Samsung S23 most carriers are offering.
2. NUU B20 being new is an affordable price ( I got sticker shock on other phones: especially "refurbished" phones wanting to much money I didn't want to buy a used phone).
3. It had the features the person wanted and color.
4. It came with a Standard charger Plug (it would have been nice to have an 18W quick Charger Plug USB-C Input, their cords are USB-C male to USB-C male) most Samsung phones now don't come with a charger plug.
5. It has the slot to add a memory card to phone.
6. It came with a screen protector with the phone but it was "cracked" in several places like someone else said. Maybe ship with stronger screen protector included.
Cons
1. It says "unlocked" I put in the old SIM card into the B20 and I got partial calls and Texts. Per the carrier T-Mobile they said this phone was "NOT UNLOCKED". I had to go in and get another SIM card from T-Mobile.
2. The USB-C cord that came with the phone was "extremely tight" to fit into phone. It was so difficult that I didn't try to force the provided NUU B20 cord in. I got some other USB-C cords I had and used one of them that "fit looser, not so hard" to fit into the phone, I believe "if it don't fit don't force it". I would have liked a 18W quick charger plug but I'll get one later to give the gift person.
3. The headphone jack at the bottom of the phone, the description says "3.5" input jack, I've tried several headphones with a "3.5" male plug and they would stop have halfway, those that had a microphone to speak into the phone, the earphones with no microphone fit but who wants earphones without a mic to talk with so again I didn't force the cord in, I'll have to tell the gift person they may need to use a Bluetooth earpiece.
4. NO SCREEN MIRRORING on phone at all ( like Smartview or Miracast or Screen mirroring or Screen Cast). Nothing to project photos and videos from phone to TV or a Firestick, I'm not getting a Chromecast dongle. It will Mirror to a google cast device like Chromecast or Google Nest but I don't have those just a flatscreen and a Firestick. If this phone had mirroring capabilities I would have given it another star. The gift person's old phone could do Mirroring.
5. Phone is having a problem with Google Meet app with it staying on to receive aka Meet or old DUO calls. I have to remember to tap Meet on phone. I'll contact Google support on this, other apps works fine.
6. I had to get some USB-C adapter plugs to transfer over old data from one phone to the other. I'll probably will use the app SmartSwitch from playstore next time.
All I can say is wow. Contacts and apps transfered over in minutes. Up and running in less than 10 minutes. Works as if I never switched phones. This thing is amazing. Resolution, pictures, speed and solid android performance. Did I say this thing takes amazing pictures? Well, it takes better pictures than any phone I've ever had. Hands down!
I will be sticking with this brand from now on. How can you beat this phone for the price?
Thank you NUU for making a great product.
UPDATE: One quick update, though the phone takes great photos, after a software update all photos are now watermarked with "shot on NUU B15" in the lower left of every photo. So far, I have not been able to remove this photo marking within settings. I have contacted the seller and will wait to see what they say. If this is not removable, this review will have to be dropped to 1 star.
One more UPDATE: wish I could move this review to 6 stars. Branding icon in camera removed. Seller responded to question within a few hours through Amazon. Problem solved. There is a settings icon on the upper left corner of the camera and selection unchecked for branding photos. Problem solved. Back to using my new favorite phone. Thanks again NUU.
All of the other specs-- 5G, decent camera, decent screen, headphone jack, expandable storage, etc. are as advertised and great for the price. This phone punches above its class and easily could be sold for twice as much. Really wanted to keep the phone, but couldn't due to the Bluetooth issue.
Still giving it 4 stars because it could be an issue only I experienced for some reason.
