Hi All, I have just bought a new Samsung Galaxy J5 in the UK. For the last two years I have been using a Galaxy S3. Whilst both have S Planner as the default calendar app -the version on my J5 is newer and does not contain the display layout functionality & ability to add icons as per the previous 4.3 version I was using on my S3. My new J5 is on Android version 5.1.1. Could anyone please advise if it is possible to install S Planner version 4.3 on this device & how I could do this? Many thanks for your help.
