“Cyanogen, a company known for its free, open source operating system and community built distribution of Android for smartphones and tablets, finally received Google’s approval to produce the Oppo N1 phone after previously warning them in Nov. 2013 that its installer encourages phone owners to void their warranty. Cyanogen reportedly pulled out its installer from Google Play after the said warning, but now, it looks like they’re back on Google Play because of Google’s blessing. This is perfect timing for both Google and Cyanogen because Cyanogen just announced that it will release the +CyanogenMod version (Cyanogen’s version of Android) of the Oppo N1 phone on Dec. 24, 2013.”
