Linux on Android related question

[Amos Shapira]

Just a few weeks ago I read (I think on DarkReading) that there are many
cheap phones which come with malware built in. I google'd for this when I
found this link:

Bottom line - avoid these devices, and if already got them then see whether
you can wipe them out completely and replace with an open ROM like
CyanogenMod (http://www.cyanogenmod.org/) or others
(http://www.needrom.com/category/coolpad/)
