Hey guys i am new to the forum but not completely new to an android. I had a G1 a couple years back then i went to a iphone 3gs and i am back with my Galaxy Nexus. Now the problems i am having: 1. when listening to the stock player when i use the headphones button to pause it i have to actually turn my screen back on to restart it. Pressing the button doesnt open it back up like i would think it should. 2. I have a PIN number set to log into the phone i want to change it to the buttons or face unlock but it wont let me do it for some reason. Is there a way to fix it? So far these are the only issues(besides battery not lasting that long) that i have. Any help on these would be great.
