Samsung Galaxy S8+ reviews

Galaxy S8+ SM-G955U 64GB Smartphone (Unlocked, Midnight Black) is rated 4.3 out of 5 by 97.
Rated 3 out of 5 by from Great phone, but.... This is just my opinion... So, I love this phone compared to my IPhone. Performs well and I love the features and the camera is great! But!.... if you don't put a case and screen protector on it you will break it. No avoiding it. It's prone to damage with its curved design and all glass. Fell out of my pocket from a bench and it shattered the back... Come on! This is 3 days of owning it with my case coming in the mail... Also I placed it in a beach bag and somehow got a scratch deep enough on the screen you can stick your fingernail in it... So much for Gorilla glass I guess. Anyways, I love the phone. Just please put a case on it from day one.

Rated 1 out of 5 by from Software Experience Ruined the Great Hardware This is my first & last Samsung phone. It has one of the best hardware builds in the market but software ruined everything. I don't like all the Samsung bloatware (some can be removed), but understand their decision for promoting their service, but why can't I even remove Facebook app. And Bixby... I don't need to talk about how bad & useless it is, but it still holds a physical button that could not be remapped. The system is showing glitches from time to time. Opening the app drawer is never smooth. I have iPhone 6s+ and Pixel, both phones are much more smoother than S8+.

Rated 5 out of 5 by from Simply Great! The Samsung Galaxy S8+ is the best phone on the market. The battery life is amazing! It lasts all day and charges really fast! I've been using Android phones for years. But when the phones battery became non-removable I had to switch to an iPhone because my battery would drain before noon. It doesn't make sense to have a fancy phone that you can't use! As always, the screen resolution is crystal clear! Everything is vivid when I am watching a movie or going through my photos. My only wish is that they make the fingerprint reader in a more accessible location, like the Nexus 6P, but otherwise the phone is flawless. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from To INIFINITY and Beyond alright i dont know where to start but first of all, i was an iphone fan, and when samsung release the s8 it got me thinking to buy one. When i have it, i was so amazed by the design ( i dont like where they put the finger print) the quality of the phone and the features is so amazing. It feels like i dont wanna go back to being an iphone fan boy. SAMSUNG rock!!

Rated 5 out of 5 by from WONDERFUL LOOKING PHONE I really like this phone, i would recommend it to my friends. BUT after seeing the NEGATIVE REVIEWS, I HOPE THAT I DONT REGRET BUYING IT. Samsung, what are you doing for the people that have complained about the screens breaking for NO reason? Are you trying to make it right? Will this be like the Note 7? Wait until people get hurt due to fire, then you RECALL THE PRODUCT? Luckily PEOPLE still support you and buy your products. How much will it cost you to make it right with the few people that have broken screens on thier phone? Especially if its not thier fault.... ANYWAY, I HOPE YOU GET THIS SITUTATION RESOLVED. I HAVE CONVINCED MY SON AND MY FIANCE TO PURCHASE YOUR S8+

Rated 5 out of 5 by from Amazing flagship Android device Upgraded from a fairly old phone (the Nexus 5), so this was a huge leap to the next generation for sure! The photos it takes completely rivals any other phone I've seen (including my husband's S7!) and not to mention it even seems sharper than my friends' iPhone pics. The phone, albeit on the large side, has an absolutely GORGEOUS screen and makes browsing and interacting an absolute pleasure every time I fire it up. Only drawback is that it's very difficult for one handed operations, but I'm not going to ding the number of stars for that because I knew what I was getting myself signed up for when purchasing such a large phone.

Rated 1 out of 5 by from This product is terrible Don't waste your money. Yes, the camera quality is nice, and the phone is small and portable, but it is too fragile! I bought my phone six months ago and yes I dropped it a couple of times, and I did have to get my screen repaired once, but after that one time incident, I bought a hard case and a screen protector, but something on the inside is broken. On my screen, there was a black dot and a line cut across the phone. As time went on, half of my screen (where the line is) glitches to all white. I've spent too much money on this phone in such a short amount of time. I really do regret buying this phone.
