I am an electronics professional, spare parts are welded through the SMT process, it is not easy to drop it down, generally will not fall out of anything, will only have an impact on precision instruments, such as said upstairs, gravity sensing, cameras, screens and other fragile products or batteries and other loose accessories have an impact! WiFi has little impact
Under normal circumstances, it does not affect wifi, but if it leads to the welding spot in the middle of the double-layer motherboard in the case of heavy falls, falling off will affect the performance of the motherboard, including frequent crashes, restarts, of course, WiFi no signal is normal
