Fast as an S6 for half the price!
I was very impressed with the phone and the company. Was as described, no external usage marks or scratches. Accessories were poor quality, but that doesn't matter. The phone automatically updated to Android 6.0.1, and it picks up 4, 3, and 2G signals on the Vodaphone network well. I can't really see any disadvantages of using this Korean phone internationally. Battery is fairly good for a QHD screen smartphone, but will only get up to two days of moderate use. Screen is fairly bright, but has trouble in full sunlight. It takes USB 3.0 plugs as well as standard micro USB plugs. Phone is quick to navigate and load, camera is good, look up professional reviews for more info.
P.S. If you dislike the inbuilt apps and settings, look up three words, ROOT, TWRP and XPOSED for this phone. It will fix all of your problems, I assure you!
