Components missing on the PCB

I got here an iPhone 5 which has 3 missing components on the logic board (check picture). It's the third, fourth and fifth component on the row. On first sight I didn't found problems. For what are those components? Are they necessary?

Gauthier Top, you did not tell us if you counted from L to R. Anyhow, that is the way I went, see attached image for reference designator.

C56 0.1UF 20% 6.3V X5R-CERM 01005

available right here

C210 56PF 5% 6.3V NP0-C0G 01005

C211 56PF 5% 6.3V NP0-C0G 01005

(yes, they are identical;-)

available right here. Looking at the schematic, it appears that all off them are part of the proximity circuitry.

Hi gauthier !

You may know that there are different iPhone 5 models. Some components are placed differently on these and their miss is not necessarily a factory fail.

Sometimes, the differences are noticed in iFixit guides.

Hoping to have helped you !
