Seems you're right about the battery indicator issue, but is there anything else? And what is the possible solution? Can I downgrade to the previous version until we come up with a solid answer?
See below the output from Terminal when trying to run from there, which is followed by a blank white screen (BTW: I am totally newbie, once as a lawyer the hole smartphone issue is a matter of working tool and fun hobby mix):

Any thoughts? Thanks in advance. And despite my personal experience with this upgrade, I must greet you for the awesome work !
