Problem with VPN disconnect several times a day?

Do Samsung phones on android have more disconnect trouble when you open phone and find protection is off and needs to be switched on again?

I’ve noticed this issue on some Samsung Android models too, especially when battery optimization or background activity restrictions are enabled for the VPN app. Android tends to “sleep” apps in the background to save power, which can cause the VPN to disconnect when the phone is idle. You might want to whitelist your VPN app in battery settings and disable “Put unused apps to sleep.” Also, switching the VPN protocol (like from IKEv2 to OpenVPN) can sometimes help with stability.
