I had to start for a while this battery cover for my S3. From the processing and feel it is thanks to the aluminum plate visible the original cover and noticeably superior. Reception problems in the WLAN or normal phone reception I could not tell at first. It was only when I started to use the Galaxy as Navi, I noticed that I did not come with the aluminum cover to less than 8m accuracy, the reception and the navigation in cities has not been satisfactory in general. Then I tried it with an app for GPS reception and wireless measurement and could see significant differences in the received power. Since I again use the original battery cover, the navigation works precisely and easily.
Finally, can only be recommended for those who do not need an accurate GPS this battery cover. All use the GPS, unfortunately have to take distance. Unfortunately, since the processing is really great.
