XIAOMI REDMI NOTE3 maintanence is difficult because of in this phone when your screen broke you also realise that how this cellphone is bad because the new display cost is too high as comparison to other mobile phones because the main reason of its high cost is when this mobile phone glass will broke you need to change both display and touch and both are combined so for that reason this broken cost is too high and overall this phone is good but this one problem is bad and the service of this cellphone is bad because this phone is new on the market. Thankyou!
