Iphone 6 plus screen problem

ok so im having a problem with my screen. the right side has lines going from top to bottom.
if i press the screen near the ear piece they go away. however most the time the screen comes unresponsive. untill i press the lock button and than turn screen back on.
i have no more warranty left, however only warranty my phone is elegible under is the isight camera one which is for phones that have problems with their camera.

does anyone think if i take my phone to apple and tell them i occasionaly have problems with the camera on and off they will replace my whole phone??

has anyone tried this or taken their phone in for the camera warranty and didnt actually have a problem?
really dont want to sink 150-175 into a screen replacement...
