Two iphone 4s pieces that i dont know their origin

[ebvillela]

Hi guys

I`m at my first time opening my iphone 4s in order to change the broken screen

i did everything quite correctly, but i`m also quite distracted and at the end there were these two pieces that i don't know where they are from

Also everything was functioning, except for the power button, so probably the pieces are from somewhere over there

Could you guys identify it for me please?

Thank you

yes, thank you, but i actually used their assembling videos to do it, and watching again didn`t noted the pieces
