Preview of Music Tracks with Manual cum Proximity Time Extension and Shake to Change Track:
Preview duration is to be input in seconds in the initial pop up window.
The time can be extended by selecting Yes in another pop window appear at the end of above set duration but within 10 sec.
Further it can also be extended to a duration equivalent to coverage duration of the proximity sensor
(e.g. put a finger on sensor or put the phone upside down on some surface to extend the time , if phone has optical proximity sensor).
If you shake it will change to next track.
The music app used is "Music Folder Player full version" by Zorillasoft (with configuration at Music Folder Player: Options indicated by three vertical dots at RHS top > Preferences > Behaviour > select Auto-Resume Folder and Auto-Resume at Start)
(the flow can be edited to accommodate any duration and any music player with compatible features).
It functions similar to foo_seek.dll or foo_preview of Desktop Foobar 2000 and much more.
Start this flow, it will start the above music player,
Stopping the music player is sufficient (the flow will stop at end not to waste battery).
The play will resume after finishing a call of any duration on dual sim phone (at present sim1 is airtel, and sim 2 is BSNL , not checked by changing sim cos)
It is more advanced but consumes little bit more battery by waking up screen for extension option selection.
