[Help] Which brand of mobile phone in Wansheng needs special maintenance?

Special maintenance is generally located in the main city. In Chongqing, it is mainly from Shiqiaopu to Daping. They are basically famous brands. Wansheng belongs to a county and city, so there is no need to point out the maintenance. It is better to buy licensed mobile phones online than in Wansheng Gome. Their target price is just a reference price. In fact, when you buy it, they will give you the reserve price, which is quite cheap and the after-sales service is guaranteed. A friend of mine just bought a mobile phone of more than 3,000 yuan in Gome, and felt very relieved.
