Indeed. Keep the hardware on the version of iOS that the tablet originally shipped with when first introduced by Apple, as long as it is still supported by GO 4. The iOS version is optimized for the hardware that introduced it! Best way to ruin an older tablet/phone is to keep updating the iOS version, which is designed for newer, faster hardware! IOS 11 ruined my iPhone 6+, which was working perfectly under 10.3.3. Now sluggish as molasses and unusable! Takes 10-15 seconds for every app to boot, including the camera, mail, text, and settings!![]()
This applies to android devices and laptops also.
