If you've managed to snag a Galaxy S4 recently, chances are you might be feeling a little overwhelmed with the smorgasbord of settings, menus and options to play with. Thankfully, O2 Guru TV's Maddie is here to hold your hand and walk you seven tricks you've probably been too busy playing Candy Crush to discover.
Battery's always been a problem for smartphones -- no-one likes the friend that dies on them when it's 2am and you need to get home drunk -- so unsurprisingly, some of the top tips are on saving battery life. Whether it's putting Wi-Fi on a timer (which is probably something we should do to help with our productivity anyway), or using the built-in power saver mode, these should help.
The other tricks are more varied and a little counterintuitive -- it doesn't make sense on first thought that disabling Samsung's built-in S Voice app would make the home button work faster, for example. But either way, you're almost guaranteed to learn something.
Of course, even if you're not a Galaxy S4 owner -- or heck, not even an O2 customer -- the Gurus would still love to have a good jaw-wag about all things tech, be it online, over the phone or in-store.
