The google talkback is spokes what you are doing.This very helpful for blind , if you are opening app it tells the app name before opening , if it is wrong app then you can change it.for them it is so easy to access the mobile.if on it with out knowing the controls you will strugle for this you have to double or triple click to open any thing when you on the google talk back.In my opinon it is very nice feature and very helpful for them.No need to take help form others they can use by they own.Such a great app.google should take more updates and more information in this
you can do any thing.mm
