Stay safe, and customize responsibly.

If you love Nova Launcher, buy it officially. If you cannot pay, use open-source alternatives. Do not install a Mod APK. Your banking details and personal photos are worth more than $4.99.

While the mod might work for a few weeks, the eventual glitches, the lack of updates, and the high probability of malware turning your phone into a zombie botnet are simply not worth saving five dollars.
