What customers say about "Processor"
Samsung Galaxy S9 GSM Unlocked, 64gb, Lilac Purple
  • This phone is excellent, Its fast, it's thin, it's practical, and the camera and gaming performance is great
  • Fastest smartphone on the planet and maybe the smartest also.
  • Everything seems to download faster as well on this device.
  • Getting back to the phone, the S9+ seems to work VERY fast when loading apps and pages. I use it for a lot of my wireless products at home (Nest thermostat, wireless cameras, LIFX lights, Liftmaster garage door opener) and all work fast and flawlessly.
Samsung Galaxy S7 (SM-G930A) Unlocked Smartphone, Black Onyx
  • With the snapdragon processor and 4 gig of RAM, this phone is quick to run your programs without lag. More than enough storage even without an SD card.
  • Obviously it has faster processor, latest android version and other software enhancements.
  • This phone is great for multitasking with its split screen support, and the processor is able to keep up with several open remote connections at once.
  • Updating from Galaxy S5, noticing that the processor gets very hot when in operation, just like the S5.

What customers say about "Camera"
Samsung Galaxy S9 GSM Unlocked, 64gb, Lilac Purple
  • Also, the Bixby AI camera function is very cool too. There are about 8 or 9 different things it can do with the camera.
  • The camera is nice, the pictures come out clean and clear.
  • The camera is beautiful and I could easily say justifies the pricepoint for those looking at the market for photography in comparison to other phones I've seen and I haven't even touched many of the features.
  • The camera. WOW. They are getting close to SLR quality with these lenses. It's not the same but I'm sure I could fool some with it.
Samsung Galaxy S7 (SM-G930A) Unlocked Smartphone, Black Onyx
  • Phone is nice and light, camera takes awesome pictures and when watching a video or movie, the picture is so clear and detailed
  • While the Camera on the Galaxy S5 was goo, the camera on the S7 jumps leaps and bounds further, Would recommend this product toa friend (and a foe!)
  • Nice screen, easy to use, great color, camera unbelievably works great in dark, much better than iPhone.
  • Great camera with good night capability.
  • The camera was really good but it sure didn't last very long on batteries got awful hot

What customers say about "Features"
Samsung Galaxy S9 GSM Unlocked, 64gb, Lilac Purple
  • I had a very important conferance call today and when I used the speaker phone the sound was crystal clear. Everyone could hear! Excellent sound quality!
  • This is my third Galaxy. I love it. The curved sides that create the 3d effect are awesome.
  • Phone came with charger, USB cable and USB connector. No documentation, SIM card, or SD card were included. I placed the SIM card and SD from my old phone into it and continued with set up. No problems at all so far.
  • The Android system on the samsung is always awsome, no lag on the operating
  • One problem when using the shop Samsung app the display doesn't show
Samsung Galaxy S7 (SM-G930A) Unlocked Smartphone, Black Onyx
  • Love that is waterproof and has a sd slot
  • Bought this phone because of water resistance features...and has already survived two dunks in water. Extremely satisfied.
  • It's not too big, very good looking, lots of storage, easy to operate, love the fingerprint ID function.
  • Works great, speaker is loud, screen is bright, touch screen sensitive, and very good looking.
  • One thing that Samsung can improve upon though is the slot for the SD (memory) and SIM card. Putting in a micro card for memory and SIM is tricky and requires a steady hand
