In addition, I have not seen the fact that the market is called 5 Megapixel Camera module --- entirely by electrostatic adsorption, in fact, it really only electrets static, is not permanent, so the only result a rubber band attached to plastic materials, different processes and effects, the current results are very good glue, thin dense, almost feel, so there is "static stickers" feeling, not on the screen, usually relatively hard and thick material, durable and handwriting screen, generally thin material, high hardness, but a good screen design stickers handwritten version, incomplete, screen size, etc. but slightly smaller, replace all four sides leaving a little gap closure, glue extremely thin, if too sticky, unloading on the screen handwriting cause permanent damage.
Do not superstition high, we must seize the decisive quality materials, from the actual results, choose your favorite camera module . But do not be cheap, cheap quality release, something else is not good, a cumulative basis, frequent replacement of the trouble and risks that may affect the machine does not appear cost-effective.
