I have an issue on my Galaxy s2 i9100 with this almost perfect rom by Sale : I9100 AOSP NeatROM.
Since the first version MTP usb freeze during file transfert between phone and PC when screen goes OFF.
I have to reboot my phone for it to be recognize again by PC.
I figured out that if I keep the sceen of the phone ON while transfering, no problem everything goes fine !
If I let the screen go OFF, the transfert freezes each time.
I gess it as something to do with sleep mode ?!
I have last version of the rom (2.5) and did a clean install.
I hade the same issue with previous versions.
I want to keep MTP (don't like mass storage).
I tried to turn off USB debuging, it seems to work but I need USB debuging !
In this thread somebody is talking about security issue...
If anybody as a solution to correct this issue it would be great !
Thanks for any answer.
