I have an old Galaxy Tab 2 for Chromecast videos and for FR when I’m not on a PC.
I’m not too worried. I do nothing fancy or personal on it as it can barely do much right now being so old.
Your choice, but as I mentioned above in #20, it's surprising how a little seemingly innocent information can be used and exploited by sufficiently motivated hackers.
I would hate to see a fellow FReeper harmed, so I encourage you to take precautions, assuming your device's manufacturer comes out with a patch. If they don't because it's too old, I will hope for the best for you and it.
