About this issue. I don't use any external hardware that uses OTG and when the issue was first brought to me it has just late. My only clue right now it's an issue with a kernel upstream patch, notified the contribuitor that helps me with the kernel version patches and hopefully will get it fixed in the next RC and OTA.

@nitanmarcel Looks not that difficult, I have to remember to get it the way it was before the OTA update. Do you have any information when it will be released?

@jakub Both slots work equally, calls and messages, but data to connect to the internet is done by one SIM, you can choose which one from the settings.
