Indeed installation is easy, we clean the surface, it is ensured that there was no dust and is asking simply, it sticks itself gradually. As against the Note 4 has a convex screen! and I thought that the protection would also result once installed it should be noted that there are about 2.5 mm on each side which is not covered by the protection, but in addition there is also about 2.5mm on all edges or protection is not glued. In short the rendering is horrible! even persisting in supporting the edges they do not stick (logical screen is curved). I do not recommend this purchase.
