I noticed that Kirishima has 2 different phones : one is the clone of Yoshino's (seems to be an iphone) and the other has a keyboard (like a motorola);
At the aquarium, he received a notification on the iphone (which is in his right hand) and Yoshino seems to be looking at the phone a lot. Then the phone is in his left hand (maybe a different phone) and his other hand is inside is pocket.
Near the end of the last chapter, he is called on his real phone (the motorola one) by Yoshino. (〜￣△￣)〜
