Looks like You're running the app inside emulator. It should be mentioned that emulator is much slower than actual devices.

Unfortunately, images is not hi-res and I cannot see details, but main thread looks fine without any very long calls.

While doing profiling task I usually look for places suspected to slow down the performance and place Debug.startMethodTracing() and Debug.stopMethodTracing() around that places. E.g. if some Activity is very slow, then place it in OnStart() / OnStop() of the activity. After that, just use Find: traceview line to find Your package class and determine performance bottlenecks.
