Unfortunately crashes

I have a Nexus now scarce 2 1/2 weeks in use and the device is now the third time I crashed (boots just new). Also an update to the current version 4.1.2 as well as the reset to factory settings did not lead to solving the problem. I'll return the device therefore. Some recessions here describes that the problem with Samsung is well known and well here is to respond accordingly. To this end, but I can not say anything.
Nevertheless, the device has left a very positive impression on me. The most positive is probably the rapid deployment of updates by Google to name itself. Furthermore, I found positive, as the "pure" Android is installed on the Nexus devices that company-specific app's such as. Samsung Market Place etc. are completely missing and therefore do not eat into the performance. However, a disadvantage in this way is that positive applications such as AllShare are not installed. Here one has to if necessary. Search through the marketplace for alternatives. I installed Skifta beta. Worked great. The update to Jellybean lies to import easily via OTA and brings a great performance with them. I have not added any Samsung devices used since convinced me that Amoled display never really. In terms of brightness of the colors I like other manufacturers better but the black and playback at Amoled already super. But that's a matter of taste. I've previously a quad-core smartphone of another Korean manufacturer used what I had, however, return for dust under the display (!). In direct comparison to the speed can personally probably say that downloads and install applications on a quad-core device go a bit faster for me. For "normal" use of telephone, e-mail retrieval and a little browsing the distance is only minimally noticeable. "Gamers and gamers" see the certainly somewhat different but also all depends on the user.
What convinced me the camera. Although only 5MP camera is super fast and makes high-quality images.
The battery Rela- loose a day like most Smartphones-. When the power-hungry also exhibits longer.
The lack of opportunity for inserting an SD card bothers me personally less. 16GB are perfectly adequate for my needs.
Although the device has been available since late last year, it is still up to date and very well served with the unit in my opinion. Especially in regard to further update by Google one can expect certainly still a lot.
However, crashes me have a little scared and I'll probably switch to the big brother of Samsung.
