Tempered Glass screen protector issue

[Menes009]

I have a Huawei P7, i was using a plastic screen protector but a about two weeks ago i removed the pastic one and installed a tempered glass on it. The instalation was perfect, with zero bubbles and zero spiderwebs, but now after two weeks in the area near the corner near the front camera a kind of air bubble/spiderweb appeared and is growing each day. Do you know any solutions to this?
