The InstaWiFi app is probably one of the coolest apps you can install on your Samsung Galaxy A3 device once you have access to the root file system. The access to the root file system is what we can root access for short. The InstaWiFi app lets users connect and share WiFi networks with an NFC tag. You can also choose to connect via a QR code if that’s your thing.

- Check the app drawer on your A3 device for the SuperSU app. the SuperSU app is normally installed by default with the CF-Root and CF-Auto-Root rooting tool since it is made by the same developer (Chainfire).

The SuperSU application is what keeps your device safe from malware and any vorus that might try to get access to your Samsung Galaxy A3 root file system.
