Should I upgrade my iPhone 4s to iOS 8?

Should I upgrade my iPhone 4s to iOS 8?

If your phone works good and already has iOS 7 then I would wait until you upgrade as your phone is low end. Thats just my opinion, anything above 4S I would upgrade. The key is if you have 7 already as all apps are made for 7 and later.

If you have enough storage then yes.

IOS 8 still has some bugs if you really want to upgrade it would be best to wait.

From what I've heard, I'd avoid it. It doesn't support a lot of the iOS 8 features, and can make the phone run slowly.
