When one or few complain you mark them as haters, but when many complain all over the world, there is serious issue, I bought this phone October 2017, it has been 8 months, initially the phone work fine with Nougat, ever since Oreo update it bring many issues.
Weak signal, Slow GPS, apps auto shut down, random reboot.
The main camera almost useless in low light condition, photo are grain and noisy, I wonder why Xiaomi actually put in a FM Radio when there is no widge to activate it.
The update is also slow compare to Nokia, which make me wonder how on Earth it considered as Android One phone.
