I'm getting frequent ads in phone app, while attending a call or while
making a call, I'm getting this ads. After the call gets over If we are
not locking the screen then these ads never goes to sleep and makes the
display alive and drains the batter...
thanks for your suggestion, during the ad display I checked play store
as per suggestion and found my bsnl app in last use list. never open
this app today. so this app could be creating this random ads.
