How do I completely disable talkback off of my Alcatel onetouch?

[AC Question]

So, I've been having problems with talkback on my phone, I tried disabling it and changing all the settings but when I start an app like Pandora, the application continues talking even after I disabled it. Another example is when I go on Facebook or the Internet, there's a yellow box that appears and it starts reading whatever is in the box and I have explore by touch off. Help me, it's so annoying.
