Again, just so everyone knows…
The LEM P, Prime S, Optimus 2 and any of the other supposedly “Dual Mode” watches are not Dual Mode in reality.
Unlike the original Optimus watches that did have “dual operating mode” and the watch would boot into the BT environment.
This is because the Dual System mode is actually just a cut down version of the launcher that prevents the user from using the majority of Android apps and some services. So booting into the BT system is not required and does not happen. The BT system chip in this case is used to handle the sensor information and it does a good job of this.
On these devices, when you use the “other” operating mode you are effectively invoking a strict power saving mode - but only because the launcher changes and prevents you from accessing the regular apps.
Hence if you can get around the restricted launcher - phone calls and everything else still works as normal. You can easily verify this by installing a third party launcher.
I am saying this because I believe it is fair to be honest about the so called “Dual System” mode and I believe that the brands have not been completely transparent about this.
In fact, to the extent that I actually believed (before I got the devices) that they were indeed like the original Optimus watches and we would be booting into the BT chip environment.
Just an FYI…
