VPN and HTTPS proxy
VPN browsers automatically unblocks websites, encrypts your internet traffic, and makes you anonymous. Unlike all other web browser apps for Android, VPN Proxy Browser is not bloated with unnecessary features. It just focuses on unblocking sites and encrypting your internet traffic.

Other secure browsers
Tor Browser for Android is the only official mobile browser supported by the Tor Project, developers of the world’s strongest tool for privacy and freedom online. Tor Browser is 100% free and open source
Tor is not really a VPN, but it is close enough to one and useful enough that we feel it worth mentioning here. All Tor browser connections are routed through the Tor network, which is to say they are forwarded through at least volunteer-run “nodes,” with your data being re-encrypted each time.
Detractors say Tor is slow and 20% of traffic is spied at the last node.
