When I don't use the mainstream camera app from Asus the camera quality drops drastically. This happens with every app: Instagram (stories), WhatsApp (sending photos to my friend), Skype (video calls).
In the screenshot you can see me in the left and one of my classmates in the right (this is Skype). There is surely something wrong with the camera software, because my WiFi signal is very strong (i tested it). Also, if I use the standard camera app from Asus everything works really well.
This happens with almost every app that uses the camera (front and back)
