THE Asus canceled the update of the Zenfone 4 to Android 9 Pie: she says she will keep it on the Oreo “to preserve system performance and stability”. The cell phone received a beta version of Pie, as well as the Zenfone 4 Max, Zenfone 4 Max Pro, Zenfone 4 Selfie and Zenfone Max Plus (M1); on all of these devices, the manufacturer offers a way to get back to the Oreo.
“To preserve the performance and stability of the Zenfone 4 (ZE554KL) system, Asus has no plans to upgrade to Android 9 (Pie), but will continue to support Android Oreo,” explains the company on your official forum.
“The beta version of Android 9 (Pie) Beta will not be supported or routinely updated,” warns Asus. “We apologize for any inconvenience caused and thank you for your understanding.”
If you want to uninstall Android Pie beta from your Zenfone 4, Asus offers a downgrade tool for the Oreo – instructions are on this link (in English). A microSD card is required to install; all data will be erased from the device.
The tool also works for Zenfone 4 Max, Zenfone 4 Max Pro, Zenfone 4 Selfie and Zenfone Max (M1). They received Android Pie in beta and should not be upgraded to a final version, remaining on Oreo.
