This is a strange and annoying problem of two parts that I have with my N97.
When I plug it into the charger at night, it SHOULD go into charging mode which sees the handset screen light up, the little light by the USB port come on and then the screen turning off.
However, I find that about 45-50% of the time it doesn't do this. The screen comes on but there is no charging lamp and the screen stays on with the NOKIA logo in it's usual place. No charging is taking place and I'm sure if left in this state, the NOKIA logo would eventually burn onto the screen. To remedy this, I unplug the charger and plug it back in again after the screen has turned off. This invariably sorts it and the phone goes into it's proper charge mode.
The second part of the problem comes when I turn the handset on. At a similar level of frequency to the charging issue, the phone will either turn on normally or the screen will illuminate and then just sit there. The only way to get out of this is to remove the battery and re-insert it and start again.
On one occasion, the phone would neither charge or turn on and it was only the Vulcan death grip reset manoeuvre that allowed me to get the phone back on. Naturally, I lost a lot of data doing that.
I'm pretty sure it has only started doing this since the v20 upgrade so I'm hoping a v21 or higher update will sort it.
Anyone else encountering this?
