Known Constraints and Workarounds
• WiFi sleep policy set to “Always” (Android O limitation)
• As GMS Restricted Mode is available in this release, Customers using Enable/Disable GMS apps may want to
consult the settings types for App Manager, Power Manager and GMS Manager in Zebra's Tech Docs.
Functionality originally in Enable/Disable GMS apps (App Manager) has been moved to GMS Restricted Mode
(GMS Manager).
• Some devices operate at 320 dpi. This screen configuration results in the majority of the AOSP applications
displaying content consistently in both portrait and landscape modes. In most cases if the application layout is
not optimal in landscape it is optimal in portrait or vice versa. However, there are a few applications that do not
render properly in either portrait or landscape. In this case the suggested alternative is to change the display
size using the bundled Display Settings APK or use settings menu to change the display size and font size
(settings Display Advanced settings Display Size / Font Size).
• Illumination brightness is set to maximum by default for SE4710 and SE4750 Scan Engines.
