This phone has been a terrific experience. Huawei was great. They've changed, now PompMall is handling sales delivery. I was able to order directly from Huawei where service was 5 stars. Phone arrived quickly by mail. Build quality is excellent. Functionality is beautiful. Huawei has regularly updated EmotionUI, Huawei's skin over Android is well thought out. PlayStore had to be installed from Huawei's app store not too big of a problem. Sound is great, so is the mic - important when talking on speaker phone. Here in BC, Canada working with Bell was as simple as sliding in my existing SIM card. The only shortcoming I've experienced is Chinese characters in call alert, i.e. if not a known contact, Vancouver shows up Chinese characters. Also in one update they took away the floating calculator, which had been part of EmotionUI. Now here's the best part for any phone junkie: 2 to 3 days battery use, seriously amazing. I can think of no other phone I'd like to own right now. However, there's now the Honor X2, which looks good. My girlfriend really wants my X1 (over her Nexus 4). Did I mention Huawei's antenna, terrific reception. I always wanted an 8" screen with half decent specs going to try the Chuwi VL8 over Huawei's M1.
