This is what's happening,
New enthusist decides to upgrade to a phone that he or she sees on a online store or shop. He or she watches videos and reads about all of the mods and Roms and intricacies of Android and decides to buy a phone or dissect with their old phone.
The person that sold the phone sells many phones at at lower market price and advertises it as unlocked or for a certain carrier, and the purchaser doesn't realize that the phone has been modified with a partition that is not easily reformated.
The merchant loads his custom keys and server tracing software on the new users phone unbenownce to the purchaser. Sometimes the purchaser can think they have reset the phone and actually haven't.
The new enthusiast is now a part of the merchants not net, if the new enthusiast doesn't manage to wipe the phone correctly. Most often the merchant uses a server location in a liberal part of a swing state, mining keys and encryptions that are most often used for Bitcoin bot mining or stock market swing modeling.
This is a frustration to say the least to the new enthusiast and definitely are "life drain". It decently doesn't foster manufacturers of phones to open their devices up to open source projects.
In my opinion do this, "Pull" the predatory system load it on a emulator and have it scan low frequency stations and have it constantly publish the netstat to a public folder preferably overseas.
