Most people have said it has full HD, but there have been some doubts raised.
Sadly, GSM Arena is no longer the definitive source of information it once was. There are many errors I've spotted, and given how many people turn to it for info, it's always funny when reviews of phones make the same mistakes as they were too lazy to check and just cut and pasted.
Anyway, whatever the case, 720 or 1080, it will be a good phone if the price is right - but people shouldn't discount the current Moto G. Plenty good enough for most people.
I've now got a Wileyfox Storm for review. £200 with full HD (5.5 inch) and SD615, and it scored 35,000 on AnTuTu - which is not far behind the Galaxy Note 4 and about 2/3rds of the performance of the LG G4 (SD808). Plus it has the same camera as the Xperia Z3!
It's incredible what you can get now for £200 or less!
