Good afternoon, colleagues! Is there any kind of detailed guide for changing the battery of iPhones for people who can't see? I am asking this because the tutorials we find on the internet, mostly in video format, do not explain in much detail what should be done based on someone who is not seeing anything. I'm trying to change the battery of my iPhone 4s, for example, because it's not possible to take it to Apple due to the age of the device, but I can't even find some of the screws needed to remove the component, lol! I just wanted to know if any of you have already made the exchange and if there is any guide focused on blind people to help, because I believe that it is possible to do the procedure, in the same way that I know blind people who set up computers on their own. It is worth mentioning that I do not want to encourage anyone to do this procedure alone, and may even lose the warranty of their devices or their functionality.
