I have one and have a love/hate relationship with it.
I get the occasional spam call but I only use it to phone someone when I'm out or when the home line dies as it has been doing this last couple of days. VM Digital downside effect.
I used to use it for WhatsApp and text messages but I now access them on my Chromebook. Used it to check my FB account this morning but without FB Purity it's a pain in the behind. (Sorry if anyone on here had a weird FB post from me earlier.)
I do find it great for taking photos and use Google wallet and Stocard but, as I'm always a tad dubious of them working, I use a phone case so that I can carry around a few of my store cards, my debit card and cash. As a result it weighs far more than a basic phone and is a little too big/heavy to fit in my back pocket
