Ken has Android and he's having issues with Chromecast. Leo says that Ken's smartphone is fairly old, running Android 4.3 (too old for Chromecast compatibility). So he'll need to get a newer device under his budget of $300. Leo says that his current favourite budget smartphone is the Motorola Moto G6. He can get them unlocked directly from Motorola for under $200. Google Fi is selling the G6 for $99.
