Thanks LL and anidel, yes i found the text file i had open on my desktop in the same seconds you posted, too many virtual desktops But that did not change the behaviour. A call comes in, if i accept and talk, the whole phone crashes after i hung up . If i let it ring until the other side hangs up, crash. Only if i silence and then reject the call, all stays fine. During some tests i found out that the sim in second sim slot does only work for data, even when i deativate Sim1 in settings, calls to sim2 number are not shown. may be related. What to do now, anybody with the same experience? I do not want to be flamed again for testing unreleased versions and report bugs that propably do not exist in final early access anyway. But it could be usefull to not try recovery or updating again so the bug can be investigated imho. Where to report? EDIT: i asked in Jolla C thread but due to unofficial version it is more fitting to further discuss in 2.0.3.11 thread i think.
