How is the digital technology quality of Fengyun mobile phone in Taobao?

This is where I bought my HTC inspire4g. The quality was so bad that the screen was covered with dust in a few days and the seat was broken in a few days. I thought it was broken if it was broken. I don't need to charge my seat anyway. The battery was charged for more than 2 months, so I contacted the store and ignored it. Let me buy some more batteries from his house. Oh, my God, is this a disposable battery? If you see Fengyun Digital, please make a detour.
