The Infocus S1, released in 2016, has been praised for its stylish metal design, 5.5-inch Full HD display, and fast Helio P10 chipset. Over time, users have frequently reported issues such as Google Play errors and cache problems that prevent new app installs, network lock errors, battery drain, and occasional unresponsive touch or fingerprint sensor glitches. In rare cases, failed updates have left devices stuck on the boot screen.
This official G90-2016-0-0603-A01 firmware package is built to restore your Infocus S1 to factory condition, resolve bricking, and fix abnormal app-related errors. Flashing the stock firmware can also help resolve persistent OS bugs and is required after unsuccessful custom ROM or root attempts that disable regular updates.
