not necessary at Galaxy A3

Got the protective foils Galax A3 bought on my Lg G3 I use a sheet of glass which feels much better. I have attached the sheet on the first try without any further problems, sitting right and sees not even soo bad .. but now feels the touch screen like plastic .. clear the film is made of plastic but it takes fat and sweat like a magnet. . scroll that is difficult and you no longer slides across the display so as usual .. FYI: Did it previously two weeks without use.

I find protectors in itself very useful, however, if I have to buy myself a device just because of design and material selection I find does not fit a protective film to normal signs of use .. can anyway never be completely avoided. Then you'd have a Case also to buy .. but for which manufacturers build ever thinner smartphones when wearing then again as a lump in your pocket ..

At the Galaxy S3 is a protector feels not bad because the entire device is made of plastic to the screen .. but the Galaxy A3 I would advise against it ..
