Notes
Device is still heavy work in the progress. The following is known not to work:
- Brightness control (screen is always max brightness)
- Keyboard backlight
- Modem interrupts, it is visible on USB but other communication with it doesn't work
- pstore (needs figuring out what the reserved memory is on Android)
- See if we can use 512MB ram instead of 509MB (see dts)
- 3d shows some frame lag / misdrawing, so probably powervr clock needs adjusting
- touchscreen buttons do not work yet
- keyboard layout in Leste is not faithful to the icons on the keyboard, but rather mostly mimic droid 4
Additionally, the device suffers from random hangs while in use, causing resets. When pstore works, we can hopefully figure this out.
Also, the device often comes network locked. User:Wizzup has access to Sigmakey software and can help remotely remove the network lock.
