I have an S4. I know I'm in serious need of an upgrade. I just hate having to re-customize everything.
I don't keep any important data on mine.I honestly wouldn't trust using an old android device. so many security holes. You're asking to be hacked.
The play store might not allow it, but I was going to try doing it right from the AA website. Just a thought.JRRF, I got you beat! I still use a Galaxy S3 with 4.4.2. Play store won't let me use AA. I'm one of these weirdos that has to use something until it breaks, if it still works I'm not going to replace it!
Nope. Google only stores an authorization token on your phone.google credentials?
honestly, run lineage on it! https://download.lineageos.org/
If you lose your phone you change your password and the token is worthless.authorization token is still a credential. its a revokable credential, but fundamentally no different than username/password. In fact, in a 2FA world, it be worse for an attacker to get that token than to get your username/password.
The best defense against this is to not run your life out of your phone.It's worse than this. All versions of Android are vulnerable to a bug in the "display over all other apps" feature that Android Auto uses. This vulnerability was disclosed just last week.
