Every Mobile Operating System Explained in Detail Once upon a time, phones didn’t run iOS or Android. They ran everything else. In “Every Mobile Operating System Explained in Detail”, we go from the earliest proprietary firmware bricks like the Motorola DynaTAC, through Symbian, BlackBerry OS, Palm OS / webOS, Windows Phone, all the way to the modern giants iOS and Android — plus misfits like Tizen, Firefox OS, KaiOS, HarmonyOS, and Fire OS. You’ll see why Symbian ruled, how BlackBerry became a status symbol, why Windows Phone died despite being beautiful, and how iOS and Android crushed everyone else to take 99%+ of the market. If you ever owned a Nokia brick, a BlackBerry, or a weird phone no one remembers… this is your nostalgia trip and history lesson in one. #MobileOS #Smartphones #Android #iOS #techhistory SOME OF MY MOST POPULAR VIDEOS: 💻 Need a fast cloud VM for your own tech builds?
