Late last year Apple and Google both announced encryption for smartphones running Android or iOS in a bid to tackle government surveillance and hacking.

The move was met with heavy resistance from the FBI and NSA, both concerned the adoption of mobile encryption would stop investigations into terrorists and criminals.

It looks like Google left out the part where it allows manufacturers to essentially control the on/off switch for encryption, meaning millions of devices running Android Lollipop are still insecure.

Google didn't disclose that manufacturers have the ability to turn off encryption, meaning authorities could push partners like Samsung, HTC and Motorola to not go through with adopting encryption on Android.

The search giant reportedly found problems adding encryption on some devices, due to different components on individual smartphones. Samsung did not have encryption turned on by default on the Galaxy S6, and neither did the Moto E.

This is in stark contrast to Apple, which is capable of adding encryption to all iPhones without any problems. iOS has always been a more secure platform due to its fewer variables since Apple is the only hardware and software maker.

Mobile encryption jumbles up all of the information available on mobile device if it's broken into, meaning investigators and governments are incapable of acquiring information.

Even with the added encryption, some security experts claim surveillance groups like NSA and GCHQ will be able to collect mobile information using proxies like Facebook metadata, phone calls and data location tracking.
