I’ve got this (paid for version) on my Samsung S3 as well as one or two other Android Devices. Just demonstrated this to a colleague the other day. I put my phone back in my pocket and thought no more about it. Some time later I picked my phone up and to my horror the phone was still running (i.e. on) the battery almost half depleted. To add to the problem a text followed later from my network provided stating that I’d used my months data allowance (1.5G despite my phone stating I’d used 700 Mbytes?). In truth something I’ve never done! I trust this is going to be fixed as I’d say this a serious bug? It drained the battery and used my data allowance all in a few hours! Maybe I’ve got this wrong, comments welcome.
