you are right Vakraya Doogee, Oppo, Huawei and condor are getting popular, but they are almost the same, i think Oppo got some good selling in the past few months all that bcuz of the advertising they made and their stratgie and for the cheap price they are selling their products, i tried Doogee, Huawei is a shit and Oppo is the best one i tried so long. you have any qst about them, lemme know.
