Inexpensive, clear screen, good performance, superb battery life - good for 2 days.
Huawei's EMUI front end limits apps to the 16 GB of base (internal) memory as of v 4.1.
SD Cards can ONLY be used for non-app items like pictures, videos an the like.
So the advertising on the box 'up to 16 GB internal memory / up to 128 GB expandable (card sold separately)' which clearly states that the INTERNAL memory is expandable is a LIE.
And with 16 GB of internal memory it is easy to run out. Most others, such as Motorola, do not impose this draconian restriction.
