I am a user from China. It’s a pity that there is no Chinese service in the forum. I can’t speak English very well. The basic use of the equipment is no problem, some advanced applications will not operate. For example, how to use computers to share hard disk files? How to use Apple mobile phone to support video playback in RMVB format? Telephone customer service response is very unsatisfactory, for example, my computer taskbar I consulted does not support minimization, so far has not been resolved. I hope these questions will be answered in Chinese, otherwise there may be misunderstanding errors caused by improper translation.
