@lncx_n7 We also had good experience with DigiCal and Business Calendar 2. Personally, we use Etar and S Planner (although both crash when setting event colors). Fortunately, there are a lot of good calendar apps out there 🙂
Can't enable log to external file
When I tried to enable the log to external file I got a message about potential security risk. I selected OK but the message appeared again and again.
This happened with Android 4.4.4. The device is a RedMi 2 Pro with MUIU 220.127.116.11.
