A user reported that audible alarm notifications were not working on a high end Samsung phone.
I have not been able to work out why, so I have just published a beta version (V2.5.4) which uses audio files to make the sounds rather than a tone generator. You can test it by signing up for beta testing here: https://play.google.com/…/testing/uk.org.openseizuredetector
Has anyone else seen this problem? Please feed back any issues.
