Audio and sim issues

hi, i have a moto e5 plus, the issue with this phone is that

1: the audio output of the jack, the left side to be precise, is in complete static, i only hear static and my earphone warms up due to this, is there a way to replace the audio jack ic so the audio can be heard normaly?

2: the phone is supposed to have dual sim and i see the 2 slots but only one slot has the sim pins, is there a way to add the second sim slot pins to enable dual sim?

3: also, the phone details say that it includes a gyroscope but i did some tests and it doesn’t have it, i searched various types of gyroscope ic’s and found one very similar to it between the dual sim slot and the camera. is there a way to solder the ic to the phone?
