There are three issues here: # Will the phone work without these caps? Yes, the phone should work without these caps. They serve a purpose and ideally should be replaced but from a testing purpose, the phone will work. # Why are these caps missing? C5202_RF is next to the WLAN IC and is a typical corrosion spot on water damaged phones. The other two capacitors are also on PP_VCC_MAIN. This leads me to believe that whoever had this phone either repaired a water damage condition or tried to repair it without success. # The antenna cable was damaged. Either way, this points to previous water damage and the fact that the antenna cable is damaged and components are missing also points to a repair that is of questionable quality. If your phone works now, I would be concerned by latent issues that may crop up in the future as this phone was probably not properly decontaminated.
