FAQ

iOS status bar not aesthetically correct

Make sure you have iOS 16 or lower in the simulator (so not iOS 16.1 or higher) if you want a default status bar (time, battery, etc.) to make it the same for all screenshots.

Make sure you have iOS 15.5 or lower in the simulator for phones (such as iPhone 8 Plus) that have the carrier name in the status bar, so the plugin will remove it and add cellular signal bars.

Random errors / hangs with Android emulators

You might hit an adb bug. A symptom is that the output of the command adb -s emulator-5554 emu avd name is empty when the emulator is running (where emulator-5554 is the name of your emulator).

If the file ~/.emulator_console_auth_token exists and is empty, stop the emulator and remove the file.

See #4 for more info.
