More trouble with Samsung Tab E and CP2019

We have developed a compliance course using Captivate 2019. The course has been loaded to a Captivate verified LMS for playback on our Samsung Tab E tablets (OS Android 5.1.1) running Chrome browser (v.72.0.3626.121.) Our issue is that while running, the course just quits at different points in the playback and never in exactly the same place. The course is 17 minutes in length and may quit as many as five time. From a coding standpoint the course is very simple, so no exotic action scripting as I've check to be sure nothing has been built in that is creating this issue.

I've run the course, from the LMS, on both a wired in desktop and wifi laptop without any problems, so it's only on the tablet when the course quits and returns to the LMS page where you can click back into it. I've looked and other threads and even tried some suggested workarounds that apparently ongoing issues for Chrome 36; this included changing the noteOn and noteOff to start and stop. The stoppage can occur as soon as you enter a screen, or it may occur in the middle, and even after setting for a bit without touching anything. Thanks in advance if anyone can shed a bit of light on this issue as it will be most appreciated.

    If you can update Chrome to a current version, then that would be the first step. The next would be to enable crash reporting reporting under Settings > Privacy > Usage and crash reports. After that, re-open the training again and wait to see if it crashes. If it does, enter the following in the Chrome address bar: chrome://crashes

    The log may give you more information into what's causing the crash or direct you towards something about the course that's not playing nice.

    I guess I should ask if anyone is delivering Captivate HTML5 content on a Samsung Tab E? If so, are you experiencing any issues with the course crashing within the LMS?

    During our testing, the course crashed a total of 7 times the first time through. Thinking that maybe the tablet's memory could be an issue I re-compressed the audio from 4400 kHz 16 bit stereo to 3200 kHz 16 bit mono. The resulting smaller audio files were imported and replaced the larger audio file. The course still crashed 5 times.

    Hopefully someone can chime in here. Any input is greatly appreciated. Thanks!

    How big is the published course. Lot of people seem to ignore that the hardware of mobile devices is a lot less performant.

    Thank you for your reply Lilybiri.

    The zipped SCO weighs in at 14MB and 19MB when unzipped. There are 61 screens in the course and the crashes occur every 7 to 10 screens. A crash can happen after playback, during playback, or ever after letting the course sit for a bit. Also, crashes do not always occur on the same screens.

    Advanced Actions are pretty basic, but there is some JavaScript being called on every screen.

    The issue is only when using the Tab E. The course is stable on a Tab 4 running Chrome 40.0.2214.109 and Android 4.4.4; SM-T337V Build/KTU84P

    Again, your replay is most appreciated.
