how to upgrade IOS iphone 4 to IOS 9???

No, you cannot because the maximum firmware you can get on an iPhone 4 is iOS 7.1.2. iPhone 4 only has the A4 chip, which only supports up to iOS 7.1.2. If you want the later firmware, you need to update to the iPhone 6S or SE, which is 1 1/2 and 2 years old, and it still supports iOS 11.

No, you can't. An iPhone 4 cannot be updated to iOS 9.

The iPhone 4 is over 8 years old. The hardware in it is incapable of running the new software. Plus the developers has have stopped supporting such old hardware.Hence the reason you are not able download any applications for it. If you need to run the new software you will need to get new hardware that can run it.

If you think the Android is better then that is what you should buy.

Personally I don't think it is. I see from those with Androids that there are far more problems with it then a new iPhone.

Yes. That is correct that the iPhone 4s can be upgraded beyond iOS 7.2.1 but this thread is all about the iPhone 4 which is incapable of being upgraded beyond iOS 7.2.1.

You can't update an iPhone 4 to iOS 9. Had you read the thread before posting, that would have been clear.

The iPhone 4 is incapable of running iOS 11.

If you need to run iOS 11, you will need to recycle your obsolete iPhone 4 and replace it with a newer model capable of running iOS 11.

Buy new iPhone to replace your obsolete iphone 4 and it will be capable of running the newer versions of iOS.

No.

Still no.

No

The iPhone 4 was completely discontinued 5 1/2 years ago. It was introduced in 2010... It's obsolete. Technology marches on.

No

You do realize that an iPhone 4 is NOT the same as an iPhone 4S, right?
