Is there any way to estimate Trustonic's TEE market share among Android phones in use globally around the world? I.e. what percentage of Android phones in use have Trustonic TEE support built-in?
It looks like Trustonic's market share is 24% of all Android phones as of Mar 2015. Here is some supporting data:
According to this link, there has been over 400 millions of Android devices shipped that support Trustonic (Feb 2015). Also, it is estimated that currently we have about 2.1 billion smartphones (again, Mar 2015) with Android marketshare being 80% of smartphones, we have 1.68 billion android phones. 400 mil out of of 1.68 bil gives us approximately 24%
