I received an old iPad2 running iOS 4 which is becoming out of date as it can no longer run Netflix or 9now app, to name a few. I mostly just use it for watching Youtube videos and concerts and would like to keep this functionality.
I am looking to upgrade the operating system to iOS 9 which I believe is the last usable version on this device, just so I can run some newer apps.
I am slightly apprehensive about doing this because I have heard many reports that OS upgrades significantly slow down old Apple devices and that these updates cannot be "rolled back" or reversed.
Basically I don't want to risk updating a device that may become obsolete in 6-12 months to run most apps (due to version requirement creep) AND become super slow due to performance issues; sadly it would turn into a brick. e.g. The 9now app was working beautifully until about 6 months ago when they forced an upgrade and bumped up the minimum iOS version to 9.0.
Forgive my ignorance, but I am not an Apple user and this is my first Apple device so it's completely foreign to the Windows/Android ecosystems.
Should I update from iOS 4 on an iPad2? What OS version would you recommend?
Thanks in advance
I had an iPad 2 running iOS 9.3.5 and it was super slow everything was laggy and it would even crash sometimes.
