How do you turn on a Android phone ?

Every phone is different; if there is an end call or make call key button, hold one or the other down a few seconds. If not, there should be a small power button somewhere~

Some have a button at the top, or side, my android turns on with the end call button, like the older phones do.

Jus press n keep a button which has a symbol like this 'Θ' (d line wil b vertical instead)...

hold the power button
