Why are Android devices so slow at times

[neku]

I have noticed that some android devices are very slow, it will take 10-15 seconds to respond to any action like pressing the back key. Are the android devices like tablets hacked, is due to lack of memory or is there any other reason for slow response?

There are various reasons for this, the most common one is when you are running out of space, the phone begins to hang.

You have to know the apps that your android phone can run smoothly based on its specs. When you install apps that are bigger than the capacity of the android phone, it would hang.
