I've found some bugs in the T76ML Carta+ device software.
- Led only lights on when device is starting from Off (no charge led indication)
- Once on standby, after one minute, it goes on and into standby automatically. I don't know if this happens later more times.
- Long press in central button to on/off the light needs two press. First long press, then second long press and then switches on the light.
- Configured as resume from suspend and switch on the light, it only does it if is resumed no more than 2 minutes after suspended. If more time passes, light does not switches on.
- Sometimes frezees using native appls and stays until 10 seconds completely locked
- Batery discharges like hell (not a bug, but perhaps a needed optimization)
- Sometimes covers of the reading books shows a big question mark.
- Reading statistics behave completely random (WTF needs to be online for that?)
As a summary, a very crappy device with very crappy software, as it is very soft plastic and gets dirty very easy. It is not worth the 220 USD/EUR it costs.
