After you buy a new cell phone, do you read the instructions that come in the box? Not many of us do.
I used to skim it but now I have found a better solution. You Tube Reviews of your phone.
Search by the brand and model type. There will be several different reviews you can watch. As the reviewers talk about the phone, they tell you about all the features of the phone and then they show you how to use that feature. I have learned so much about my phone. I found out how to switch the camera to the selfie mode and back with a simple swipe up. How to set the timer option on the camera phone, hiding apps and how to get the most out of my battery. Each review will show you something different, you can watch them as many times as you want, rewind, pause while you try it on your own phone. You can save it to You Tube account to “watch later” or any folder you choose. I am sure these reviews are meant to be viewed prior to purchase but I find it to be a great tool after the fact that I highly recommend.
