First of all sorry for mistake that i wrote "when i turn navi wheel of through settings" it hangs when i turn it on, i have did everything, like formating phone/hard reset and updated software, and also flashed it as well, but it didnt help, what exactly hardware problem is? Because there is no software issue. Please advise me.

Please peoples help me
