This is a very shabby watch. The mobile phone has been used for a month, and it is very noisy. I took it for maintenance and said it was ok. Two weeks after I came back, the screen stopped displaying. After the repair, it was said that the screen wire was corroded and broken. In fact, I used it for two weeks and it was useless. Hua 80 yuan changed the display screen and asked me to send the old screen back, but I didn't send it back. After receiving it, I found that the battery could have been used for one week, but now it can only be used for two days. Not only that, there is no sound on the phone now. Damn it! I haven't repaired it for a long time. If you send it back, it is estimated that you will spend more money to buy a new battery and then replace the screen you just changed. Now that you are complaining, you should choose your friends carefully! I bought the T 1 blue model for 339 yuan, and the warranty period is 1 year.
