Just bought my Droid Maxx after coming from Galaxy Nexus (original droid before that!) - very proud of my transitions. ;-)

anyway.. i think my phone is working in solid order except a few times when using it last night for surfing or just trying different apps, the screen would turn off (lock mode) while i'm literally scrolling down a page.... even while my finger is touching the screen it turned off.. my screen timeout was set at 1 minute... after lots of tests and getting it to happen about 5 times accidentally.. i was able to figure out what triggers it... if i hold the top of my hand over the top edge of the screen (in alignment with speaker & camera) from anywhere above the surface up to about 3 inches i can get it to going into lock mode..

i've done lots of searches and many suggestions are to disable pocket detection... while thats not an option on 12.15.15/4.2.2 droid maxx...

any suggestions? should it be this sensitive? i mean its a huge problem while holding the phone in landscape mode.. it would left hand cradling top of phone, right hand cradling the bottom of phone, heck i should play riptide and see if it turns off while just driving in the game.. actually i just did another test... the phone will turn off even if just the top right or top left of the screen is close (but not touching my hand), if it touches, it drags down the notification bar..

What you're doing is essentially telling the phone that you have placed it either next to your face, in your pocket or face-down on a table. The proximity sensor that determines whether the phone is close enough to something to no longer need the screen lit is to the left of the speaker on the front face, top of the phone. The sensor is triggered at 3cm (not 3"). To see it in action, you can download and install https://play.google.com/store/search?q=proximity sensor&c=apps. It will show 100cm and a static screen (image 1 immediately below), and then as you bring your finger closer to the spot just to the left of the earpiece speaker, it will suddenly change to 3cm, and a counter will begin recording how long your finger is there (image 2). If you move your finger back away again it will revert to the 100cm.

Only thing you can do is avoid the sensor area anywhere within 3cm of the sensor. That could be tough if you're holding the phone by the top with your left hand, and with the top to your left. Try flipping the phone the other way, with the top toward your right and hold it with your left hand at the bottom instead.

Yeah, if I hold my hand over the sensor and flip the screen that way, it shuts down too.. The proximity sensor is triggering higher than 3cm on yours, but I'm not totally sure that's the problem. Since mine does essentially the same thing, I'm thinking that's just the way it is. I can't find a setting for the proximity sensor/pocket detection so I'm stumped.
