Samsung SM-J337U Reviews

Galaxy J3 (2018) SM-J337U 16GB Smartphone (Unlocked, Black) is rated 2.6 out of 5 by 14.
Rated 1 out of 5 by from Returned! After 3 weeks with this phone, I returned it to the carrier in exchange for a slightly more expensive Moto. The J3 wouldn't stay connected to WiFi, it wouldn't swivel even though the swivel was on, the speaker and mic weren't crisp and made it difficult to hear, and the speaker phone would stop working during a conversation. Also, there is no designated button to drop the keyboard, it's also the back button, so it usually doesn't work. As a personal preference, I didn't like having a physical home button. If Samsung doesn't have the integrity to make a quality phone at this price point, I will not trust them with several hundred dollars. I'll definitely be buying an iPhone.

Rated 1 out of 5 by from No audio I got my first J3 V to replace a more expensive Moto that was stolen. What a mistake. Nothing but problem, 1st wouldn't stay connected to home WIFI, 2nd lost the audio, 3rd wouldn't open web pages. Verizon sent me out a replacement phone which works...then no audio. Call to Verizon & another hour of my time lost, issue fixed, audio back for maybe 24 hours, then gone again. Now they are sending out the 3rd phone to try again. They will not let me return the phone since it has been over 14 days (although the 1st issue was 6 days after purchase) and in the mean time I can call & receive calls however the line is dead...NO AUDIO

Rated 4 out of 5 by from Amazing Features The phone itself allows you to customize most options and the level of bloatware is kept to a bare minimum. The specs aren't the best on the current market but the features are what you're looking for with this phone. An conviniently removable back cover allows you to take out the battery and replace it if you so desire, and also allows you to expand your storage with a microSD card up to 400GB. I don't see where you can go wrong with that. The phone is sturdy and I can accidentally drop it and not worry about the back of it shattering unlike most glass-backed phones. The display is wonderful and the keyboard is relieving to use. The only downside to this phone in my personal opunion is that the cameras aren't bad, but not nearly what I know Samsung can do and that there's no fingerprint scanner present. If this phone was available with top-notch specs I know that I'd buy it all over again and a fingerprint scanner I know that I'd buy it all over again. This is coming from a former Samsung Galaxy S6 user. I see two phones that can be combined to make something I'd fall in love with.

Rated 1 out of 5 by from audio problems 5 times this phone had to be reset since july 2018 . Can not answer calls and the person you call can not hear you . After a reset it starts working again.
Date published: 2018-11-14
Rated 1 out of 5 by from unimpressive This is the second Samsung phone I have had. Not impressed with either one. It is very unreliable when it comes to making and receiving phone calls. There are even times when texts don't come through. It's a glorified alarm clock.
