Is it safe to use a VPN ? Will it corrupt my android system?

Of course it is safe.I often use vpn for getting access to my forbidden media stuff. Try to check https://veepn.com/ and get needed access to netflix or youtube. Plus paid vpn works more fast than free onelike browsec

It help to protect your privacy

Yes it is safely. But anyway you should use good service for it. I prefer vpn due to guaranteed anonymity and security. And of course ease of use. The choice is yours.

Yes, absolutely safe. I am currently using https://www.vpnunlimitedapp.com/en/pricing because it's reliable and has good speed. I was using free VPN several months ago but now I prefer to connect to paid VPN because it gives me a lot of options. Safe connection, fast speed and a big variety of different connections. Free VPN has a lot of lags, poor connection and the opportunity to connect only to one device. So, anyways I prefer paid VPN, the most used is VPN Unlimited for me. Unfortunately, there are a lot of VPNs that are paid but they have poor connection, so it's better to use checked services.

Here is the info, you deicide.
