When I buy this device I was very happy but that was my mistake to buy this phone this phone got lots of issues like battery issue and some software it has no good camera front camera is too bad compare to same rang phone and battery backup was too bad it runs only 6hr only I dont know why but it good 3000mah battery but it didnt work like that after 5 months my mic voice was gone and also low volume issue in mobile speaker phone works great software is very good but there no android n update for it and it first nexus who wont get the latest update from google. I heared nexus is very good brand and trusted brand but I upset with only nexus 5 not with other.
