I got a new cell phone, unfortunately it is quite quiet and I like listening to music with headphones, all cell phone internal settings are very loud and the "apps" that promise to make the cell phone louder do not work. Are there any options? So I have a Huawei Android
No, there's not
What kind of cell phone did you get?
I mean what exactly there are many different Huawei phones
Use punctuation marks.
Try other headphones
If the unknown cell phone has a USB-C connection: Use a better adapter on the jack.
