Great Video Sir, but whats the pice on the left side of the battery?

5:07 Isopropyl alcohol melts the adhesive fast and makes the battery removal very easy.

Hey could I know if that is the Qualcomm or Exynos style phone?

If I'm just to fix the stuck volume button of regular s21, do I have to remove battery and some components of the phone? I dropped my phone and now it's stuck on safe mode.

Hi, may I know if the camera bump on s21 ultra is durable to protect the component of the cameras especially the lenses? Is it safe to put it down in a surface where the camera bump will hit it first?

Hi, what's happening if after repair and close everything, the side 5g antenna keep removing from his places! There another way to stick the antenna well then just to push it with a finger???

Always remove the sim card tray first, for the rookies out there😂

Which part of the motherboard is the power ic. I have a dead motherboard that's good and a good motherboard that's not able to activate with service.

Hello nice video. I have a question regarding the two sensors he removed between 4:50-5:00. I bought a used s21 ultra 2 weeks ago and I realist that I have awful reception. Now I opened the phone and i realist the two sensors are not in my phone and also the port on the phone where I would connect the two sensors are not there. How can that be?? I mean sometimes have reception and I also have 5G then. Is it possible that there are Models of the S21 Ultra without this to Sensors? I hope someone can help me and thanks in advance.
