To be honest, yeah I have. I've read things as intense as Yamane and Zaria's work on my phone out in public... with the straightest face. (Though I do turn my phone inward a little and glance around to see if anyone is peeking, haha).
.I do often w my phone.. I make another page w normal manga on my browser, so I can change the page when somebody come near me... plus I'm always quiet even if I'm alone, so it's fine.. yas reply
