Bought myself out of frustration because of my miserable HTC ONE this phone ......... (but that's another 'theme) To make a long story short ...... voice quality 1a. Reception quality 1a. One can call really good with the part. Calls under normal use, 20 min Whatsapp, 10 min Email, 10 SMS a day, and maybe 10 minutes the battery lasts 4 to 5 days. What I want more. The high-priced junk no longer comes into the house to me. Internet works fast and easily via Wi-Fi or mobile. I can recommend it only for free. Small drawback, it slips in hand. It's fallen down 3x, but no problems ...... For the price, what more could you want?
