The Xiaomi Mi Mix 4 will have a camera with a better sensor than Samsung's ISOCELL 64 G IS1, said Wang Teng, Xiaomi Product Manager, in response to Weibo, which has already been removed.Sony has not yet announced a 64MP sensor (although we are sure that it is approaching), so there is no direct alternative. At least not for now."Better" is of course quite vague with regard to image sensors; It may mean that it is bigger or has improved light sensitivity, it's not just about resolution.Realme has already confirmed working on a 64-megapixel phone equipped with the Samsung GW1 sensor, which we are sure will only strengthen the rivalry between the two companies.Meanwhile, the FCC has certified an Android One phone with a 48 MP camera, this looks like the Xiaomi Mi A3. This corresponds to the current rumors that the new A3 models will be based on the Mi CC9 and Mi CC9e models (respectively Mi A3 and A3 Lite).As sources say, a diagram on the back shows the same drawing with a triple camera in the upper left corner. The model number of the phone is M1906F9SH. Therefore, if this name appears in TENAA, we have more details (although we did not expect any material changes).
