It's the second week of the month and Samsung's June 2020 security patch roll-out continues, with the unlocked, US-bound Galaxy Fold and Galaxy Z Flip being the latest devices to receive the update. The new firmware for the unlocked Galaxy Fold (SM-F900U1) and Galaxy Z Flip (SM-F700U1) carries version numbers F900U1UES3BTE1 and F700U1UES1ATE3, respectively.
The international Galaxy Z Flip got the June 2020 security patch last week, and the Galaxy Fold followed suit only a couple of days later. The new updates don't bring any new notable additions or changes to the user experience, but the latest security patch fixes a variety of security issues affecting both Android OS and Samsung's proprietary software. Make sure to download it as soon as possible, and follow this link for more details on what kind of issues are addressed by the June 2020 security patch.
As always, you can download the latest update from SamMobile's firmware archive. Search for Galaxy Fold and Galaxy Z Flip firmware (or click the links), download the right package for your model number/region, and install the update using a Windows PC. Alternatively, you can wait for the update notification to arrive on your foldable phone, or open Settings, go to Software update, and tap Download and install.
