Chosen Solution

Yesterday I successfully replaced the battery in an iPhone 6. After I was finished I found two small rubber nubs (soft rubber, not broken plastic) on my work bench that I assume had fallen unnoticed out/off of the phone. The only parts and screws that I had removed were the two outside casing screws on either side of the lightning port, the battery connector cover and its two screws, and the vibrator and its the two screws. Can anyone please identify these nubs and tell me where they were from? Maybe they are superfluous and don’t need to be put back in place? It’s also possible that they came from an iPod Classic or some other device that I recently worked on. I don’t usually lose track of parts this way when opening devices, but I am an amateur, not a professional. Thanks.

im not referring to the guide, it just looks like thats where they go, i have never seen them before on countless screen replacements
