I need your one help of my Lg G Pro 2. When every time I check my balance of my phone number, its play a (big duration) ringtone/notification sound during message pop of balance information. I check every settings and even did factory reset. But I could not able to off this notification message ringtone. Its very Annoying. Is there any way to off/change this ringtone or this is a bug. My LG Pro 2 is based on D838 and I bought from Hong Kong.
BTW, my phone downloading new firmware 10 f (currently i have 10e). I heard here many 10f version problem. does the problem solve or I should ignore the update.
