There's simply no good way to be able to predict compatibility/longevity of apps/OS/devices. Sorry. We unfortunately have to continue to open our wallets.
So I'm looking at different phones like older Notes and Samsung 3s. I am afraid I won't be able to update Apps and get messages that the browser doesn't support the App etc. . . I amusing an old SGH T369, (even tried to hook up to a computer with the dial up feature! lol - didn't work. - T959V and a Note I717. the Note didn't have issues with defunctiveness, but I killed it. Now I a paranoid of how long an older phone will last before it becomes obsolete! Why can't they make them. . . LAST! and be upgradable! right. . .
