It's crucial to consider your needs when selecting an Android VPN that is free. A free service is acceptable if you only want to use the VPN for light web browsing at home or on public networks. But if you're hoping to stream videos and other content, or keep your browsing history confidential at all times then it is recommended to use a premium VPN.

The best VPNs for Android offer great performance, top mobile apps, and reliable security. Some VPNs offer a trial or a money-back guarantee so you can try them out before committing.

For example, NordVPN's 30-day money-back guarantee lets you try their services for a period of time without risk, and its dedicated Android application is well-designed and similar to its desktop counterparts. It also provides a wide variety of features, such as the kill switch, as well as DNS leak protection.

Another highly recommended service to consider is ExpressVPN that also has an individualized Android app that's easy to navigate and feature-rich. This VPN has a strong privacy policy, and it offers strong security, including AES-256 encryption and a kill switch. In addition, its fast servers ensure that your data doesn't be slowed down by delays.

Other options worth considering include Hotspot Shield which has a decent amount of bandwidth (500MB per week) and Atlas VPN which offers decent speeds, as well as nice-to-haves like split tunneling. This free service also comes with some disadvantages, such as an absence of features as well as limited server locations and inconsistency in performance.
