Bad packaging, lost components
I haven't yet tried the phone yet, but the order was delayed and arrived with the e box open and components missing. The parts were sliding around in the box. Customer support said the only option was to return it, get a refund, and order a new one. They couldn't refund or swnd just the missjng parts. I needed the item urgently, so i will have to buy the missing parts myself and hope the phone wasn't damaged in transit wrapped only in a thin piece of plastic. The device may be great, but the experiekce was not.
