I have had this mobile for a long time now, so when you put the music on without headphones and turn it up, it sounds loud and there is no problem. Now, when you use headphones and turn it up, it's like you have it in the middle (and I have changed many headphones for this reason). The front camera is the worst I have seen, blurry and cannot be fixed at all, and don't expect anything better from the back camera either. Okay, it's not as bad as the front camera, but it's not a camera for the 21st century. Shameful, especially for a new mobile. My old Samsung from 2016 was perfect in everything except for the capacity and battery, and I had it until this year, and the price was almost the same as this mobile... Also, when I receive emails, I have to enter the application to see them, even though I have selected the option for them to appear on notifications... What can I say about the camera and sound of this 21 mobile... I do not recommend it if you need it more for photos, because in other aspects, it's fine
