Did you see any calls in the call log, what I mean was the phone just silent? Just a word of warning about the rules as you described up there: setting cell id and WLAN to the same rule rarely makes sense. That kind of rule means both conditions must much, that you're in one of the specified Cell Ids AND you're connected to the specified WLAN. It's not that either of the conditions being true will make the rule active. Anyway there's no way ProfileMatic can make your phone not receive calls (except by turning on flight mode, but uninstalling ProfileMatic would not resolve the issue in that case), so whatever it was I doubt it was caused by ProfileMatic. But if you can reproduce it and let me know the exact situation and what rules you had, I can try and reproduce it myself. Anyway I will also be testing the power saving mode etc. more on my phone, but so far I have seen no problems.
