The Galaxy Z Flip 3 has been on sale for a month at this point, and its first security update came soon after it first hit retail shelves around the world. However, those who purchased the device in the USA have been waiting all this time for an update to arrive on their phones, and that day has finally come.
T-Mobile is the first US carrier to release the September security update for the Galaxy Z Flip 3. Other carriers and the unlocked model will likely follow soon. The update comes with firmware version F711USQU2AUI4. A changelog is not available at this time, but it’s likely the update includes general stability and performance improvements similar to the one that released for international models at the start of the month.
If you purchased your Galaxy Z Flip 3 from T-Mobile (or MetroPCS), you should be able to download the update over the air from the Settings » Software update menu. If that does not work, wait a few hours and try again. Or you can just download the latest firmware from our archive and install it on your phone manually using a Windows PC if waiting isn’t your thing.
