Oscilloscope for phone diagnostics

I am sorry I wasn't consistent with my YouTube posts lately, but things have been slow and was just getting boring repairs, smashed phones, nothing interesting. I don't just want to post the same type of repairs...
Here's a video that I wasn't initially considering to post, but eventually thought it might benefit some of you... It's about the use of the oscilloscope in phone and laptop repairs. It is not a must have tool, but you might find it useful. I definitely love them, and found ways to use them just to speed up my diagnostics. I won't go in depth with their usage explanation as if you want to learn to use one, you can find tons of tutorials on Youtube.
Enjoy! :)
