I am writing this because iqoo made a worst updates because even this phone is lanched 1 and half years ago and this iqoo kept this phone as old phone and stopped monthly sequrity updates and made it quarterly , even promising 2 years android updates and 3 years sequrity updates , from this conclusion is iqoo makes this situation most worst , by doing , so I am saying that don't buy iqoo mobiles ,even you mobiles also become old in 1 and half years and support also ends. Very quickly
