I'm able to replicate--we're working on it. The problem seems to be format-specific, occurring only with MP3 files. Let us know if you're seeing otherwise. See:

With Build 1.3.1.0701 there are still crossfade problems.
Now, the actual playing song shortly stops when exactly reaching the last 5 seconds. Then crossfading to next song begins.

The issue is device-specific, but I'm able to replicate on an S5/S7. We're shipping a device with the problem to the dev taking care of this. Might take a bit of time to resolve though, so you might want to switch to Gapless playback for now.

This problem persists in MMA 1.3.0.0685

I just switched from an Samsung Galaxy S4 to an Galaxy S7 (SM-G930F, Android 7.0, MMA 1.3.0.0683) and determine issues with crossfading.
With the old S4 I did not have this problem.

When a song reaches the last seconds when crossfading should begin, the song get's paused for ~0.5 second and then crossfading starts.
This is 100% reproducible but only happens when using the phone's built-in speakers. When i use my bluetooth headphones, there is no gap in the crossfade.
