Alrighty, so here's a weird one: I just did a four person group duo video chat with my entire family. My sister is using her iPad, my dad's using his Moto g5, I'm using my Pixel 3 XL, and my mom is using her Pixel 3A XL. Her phone is the only phone that provides squeaky noisy interference. She and my father in the same house stepped away from each other to create more distance for the noise frequency. However, that didn't help it because her phone was the only phone that was still noisy until she ended the call, and then went on the call with my dad. Has anyone else either experienced this or has any suggestions as to why? I'm an advanced networking person, I can't figure this one out. Lol.
