Acer Liquid Z5 Z150 I bought this new handphone on 13/3/2014 and start to use it around mid April. I am very disappointed with Acer's product because the handphone was broken down 2 times within 1 month time. It suddenly turn black screen and totally out of control and can't be switched. No response and can't re-start. Acer's technician put it as "No power, battery cannot charge up, can't turn on". The technician said it is the OS problem; it crushed with google system. After first fixing, I got the same problem after 3 weeks. How can it be like that???Even though the phone is cheap, I don't expect its performance is so lousy. I strongly request Acer to review this line of product and take back this model from the whole world and refund to customer.
