During the call notification sound is coming. Its make discomfort. Sometime notification sounds are not working. After reboot its getting normal after sometime again the same issue is coming. "Alert on call" from Phone-> Calling Accounts -> not working. If i switched on the Dolby sound on its giving high volume of notification sound during the call. This and all happened after 8.1 update only. 8.0 seems very good. Need some solution
many bug after 8.1, like phone app hang and while calls are landing it doesn't ring at all, need to restart.
