To look at remote.conf I will need both your remote.conf from Android - if you're running from SD card you should find it on your SD card as LE copies it automatically - and some debugging info. Please create a new thread so that we can fight issues there - sometimes it's hard to find issues when threads get tens of pages long.I am aware that suspend mode is not working - that's why it's a known issue. I would like to fix it but it's not that easy - otherwise it would have been solved long time ago.
