Android Question

Hey there,

My Samsung Galaxy S3 was giving me a lot of problems from when I last updated it... I couldn't receive or send text messages, and the screen would constantly freeze so much that my phone was practically useless.

I managed to back up my data and attempted a factory reset from the settings menu. Though, it's been about 12 hours and my phone has been stuck on the samsung logo page (for when it's first turning on). I thought it might be frozen again so I took out the battery and turned it on again. It ended up on the same page.

How long does a factory reset take? Is it still in progress or is there something else I should try?
