Samsung started seeding the latest iteration of its One UI to the original Galaxy Z Flip. It's not a drastic overhaul but the new version does bring several neat features.
For instance, you can now request a password for the Wi-Fi if one of your contacts is already connected to the same network. Another cool addition is to the default Samsung keyboard, which can now search on YouTube directly so you are not limited to Google searches.
The Pro Video mode of the default camera app now allows you to choose the integrated microphone while recording or an external microphone (either Bluetooth or connected to the USB-C port).
The update with build number F700U1UEU2BTGE requires a 1,157MB download and also delivers Google's August security patch.
