It's built by a company that doesn't known how to build phones or service it's customers. Their whole range is plagued with issues; screens lifting, lying about spec and getting caught, usb ports breaking, updates (which themselves are extremely rare) breaking more features than they fix, never updating the security patches, promising OS updates and never delivering them, ignoring customers with issues on their own forums, deleting threads full of people reporting issues to hide the fact, doing the same on Facebook, inventing fake competition winners on Facebook, ignoring real winners who never received their prizes....
It goes on and on. Vernee are releasing phones at a staggering rate but dropping support for them almost as soon as they are released. I'd sooner buy just about any other phone over a Vernee. Its not like mid range mediatek phones are hard to come by - that's pretty much all that comes out of China.
