I still have 13.5.1 because of the warnings about battery drain I have read in Forbes.  Now I read about a security breach and the importance of upgrading to 14.4 immediately.  I certainly do banking on my phone so that’s got my attention.  
With my older phone, should I upgrade to 14.4 and why? Thanks.
