today I discovered a "hidden" Factory Mode in the bq Aquaris E4.5 Ubuntu
Edition. It can be accessed the following way:
- Power off the device
- Press the POWER and VOLUME DOWN buttons for more than ten seconds. The
device will boot while you are pressing the buttons, so keep pressing.
In short it offers tests for all of the device's hardware components,
including cameras, Bluetooth, GPS, FM Radio etc. As far as I know this
mode is only available on devices manufactured by HTC, such as the
Aquaris E4.5 (krillin), and not on other devices such as the Meizu MX4.
I documented my findings at [1]. Would be great if somebody could fill
in the blanks, e.g. the necessary environment for the WiFi test
