Mobile World Congress 2015 doesn't officially start until Monday 2 March, but a lot of the action is happening before the show opens. We've ensconced ourselves in the Catalan capital, ready to bring you all the action.

The fun starts on Sunday 1 March, with a clash of titans. Samsung and HTC are both launching new flagship handsets and have made no secrets about that. 

On Sunday afternoon we'll first see the new HTC One M9 launched, followed a few hours later by the Samsung Galaxy S6 and S6 Edge. If you're an Android fan looking for your next super phone, this is where your attention needs to be. 

But that's not all that's lined up. There is expected to be a wide range of announcements across Sunday and Monday especially, and we're expecting to see new hardware from LG, Sony and Huawei to name but a few.

There's plenty more to come from the show floor too. Keep your eyes on our MWC 2015 home page for all the news. It's going to be a busy few days and we're going to have a lot to share with you. 

While you're savouring that thought, why not check out the best phones launched at MWC over the last 12 years or read up on what else to expect from the show?
