Vaguely remember reading about it somewhere on google...the S5 indian version is Mediatek so i dont want to shell out 17-18K and find out the gps is not performing well...on uber drivers forum people are only suggesting snapdragon +minimum 2GB ram...very popular phones preferred by uber drivers abroad are Iphone , S6,Nexus 5 and above,motorola (the moto X play doesnt have a gyro sensor even at 17K ) ...the next moto range is out of my budget as is most of these phones....so if redmi locks on GPS fast and doesnt let go then it would be awesome.
I consider the price as investment in this case so i dont have any aversion to any brand...just need the phone to perform reliably in the navigation department....just a short google search lead me to this link about oneplus one :
