Hi Friends,
A buddy of mine wants to factory reset due to virus problem and also to clean apps cluttering the internal storage. His OPO is CM 12 and few days back 350 MB update file downloaded and installed. My question is if he resets will this update file vanish ? Thanks in advance! ;)
 
If the CM12 update was installed, it won't disappear from a factory reset. However if the OPO is rooted, the malware might not go if its got into system. If its not rooted, a factory reset will clear the malware but not the CM update. And in future only install apps and games from known trusted sources, i.e. Google or Amazon only.
