I switched to Straight Talk several years ago cuz they're easy, cheap and don't care if I tether. I've had a few of their phones and they all share this shortcoming: none of them ever perform system updates. I asked the manufacturer of my current phone and they said: I request you to contact your carrier to check the current Android version available for the device. You can contact Tracfone at 1-800-867-7183. You can contact StraightTalk at 1-877-430-2355. I suppose that makes sense, but which of these is the more likely culprit?
