I have some naive question, as I have never worked with android as a whole. I am trying to undestand display framework of android.
Above is a picture that I saw in android display framework. I want to understand how this flow works.
1.After status bar how can a hardware like GPU be there...
I've had Foxfi installed on my S4 since I got it yrs ago, and it's always worked fine (I have unlimited data) until yesterday.
Went to turn it on like I usually do, & got the 'call to subscribe' message.
Nothing changed on the phone, can't figure out how to fix it.
