Close Up Disassembly of FitBit Charge 3

I documented the disassembly of my Charge 3 when I was attempting to repair it. This video is intended mostly for entertainment purposes, for those that are fascinated by electronics, but you can still gain an understanding of the inner-workings of this and similar devices.
My intention is to follow this video up with more that go in-depth and step by step for troubleshooting and replacing various components.

This was the best video I have seen about Fibit Charge 3. All my appreciation for your skills 🙏 🙌. PS. Can you please tell me the name of that glue you used as sealant?

Thanks for the vid, absolutely detailed. You just forgot to mention what was wrong with your fitbit and if you were able to get it sorted out after all the trouble you went through tearing it apart. I'm getting a 001 error, and looping smiley faces, can't even get the device to pair with my phone and sync... customer service hasn't been of much help (only thing they know is the 8sec and 15sec methods, then they ask you when the device was purchased just to see if they can replace it, mine was past the warranty period). So I'm just trying to sort it out by myself, maybe there's a way to push firmware to the device via pc, etc.

Thanks for making this video, I'm glad you exist :)

"At this scale, nothing is hard to remove if you press firmly enough" ... Do you have a brand of tools you most trust for these operations? I've been using a generic set with replaceable bits I like though haven't opened a Charge 3 yet.

Hi, what type of glue do you used, or do you prefer, to keep the water proof seal?

How come your screen does not have a digitizer? I have a charge 3 and there is a digitizer stuck to the back of the screen with a 3rd cable line...
