If you’ve read my earlier reviews of flip smartphones, you might already know that I’m a huge fan of the form factor. With technology increasingly taking up more space in our lives and handbags, I love a gadget that frees up space instead. The latest flip phone flagship to hit the streets is the OPPO Find N3 Flip. I loved last year’s version - the OPPO Find N2 Flip - so let’s see if the new version makes the love last longer.
