Phone size matter

If you thought that it doesn't matter what is the size of your mobile phone, think again.
First of all you would want to watch youtube or other video provider on a larger screen if possible so you can see more details.
Second, you want to maneuver the phone with a single hand. If you are right handed, this is equivalent to your thumb reaching out the left extreme side of the screen.
The best way to evaluate if a phones size matches your needs is to use a phone size comparison tool and compare all models with your current model.
Then you will be all set to enjoy the full experience of your next new phone.
