Sorry for my wrong pronunciation. it's PFO not BFO.
I hope you enjoy the video 😎

Thanks for this video.
I guest the capacitor is connected to the VCC of the PFO Ic which I often call the PA ic. Its terminals are connected to VBAT or VPH and GND. This is a clear indication that it's a decoupling or a smoothing capacitor whose job is mainly to remove unwanted noise or glitches and supply a nice smooth DC to the PFO ic.

It stopped charging when i took it to the repair it fixed and he told me a chipset related to motherboard is damaged thats why it wasnt charging but the mobile networks become verey bad like for 20 seconds it works normal then it stop so there is no internet for 10 seconds and it keeps jst like this also sometime one someone calles me on phone i dont recive his call and soemtimes i recieve (so i guess the sim card keeps connecting and disconnecting from acces point)
