So I downloaded the hola and the tunnel bear VPNs and everything was going fine. Then I noticed that even when I don't have any of them running I can access blocked websites like YouTube and when I open the apps to turn on/off the VPN it won't let me check the permissions box, as a result I am unable to turn off my VPN and it's a big burden on my battery. I even tried uninstalling the apps, clearing the cache partition, all of the cache and rebooting my phone, but nothing is working. And now my battery drains very quickly. I don't want to perform a factory reset and I can't stand it anymore. My phone is not rooted and its a galaxy s5.Please help.
