And try this. Turn off bluetooth in the phone.
I have recently have made the leap of faith from iPhones and purchased an android phone, i used to have an iphone 6 and now i have switched samsung galaxy s6 edge plus.
After i started using the phone back home i started emmidiatly having a problem. Every 10-15 mnts; the internet would stop working all togather, even though i would still be connected to the network with full coverage (strong signal). I would then have to disconnect and reconnect again for the internet to start working. In addition if am using an app like skype; this would occure more frequently making it ever more frustrating.
I should note that this never used to happen with my iphone nor is it happening with the other laptops , phones, tablets or tv connected to the same network.
What should i do?
