Galaxy s7 edge!! I got this phone almost 2 months ago and i cant use any of the third party applications like whatsapp, skype, viber. I can text but calls are dropping every 2 minutes or less. I have used other several phones like S4, S2 and i never had this problem before. Telus recommended me to change the sim card but didnt work. I believe i started have problems after the july 1st security patch update. Anybody have any suggestions on what to do? I am really depend on services like whatsapp and skype.
