PLEASE READ THIS: Due to a million of different android devices with custom Android OS and a lot of languages that I don't know of course and etc.
I don't know if LSubs works correctly on your devices with your languages (Native and Learning). If it doesn't work correctly or you want something else more - please don't shame and write me about it.
You can find communication channels in the LSubs: Menu->About->Community or write via email that you can find on this page.
