Your cell phone is full of survival tools.
Note, a working phone can get you rescued if you find a signal.
Only take your phone apart in a desperate situation. Or, when your phone has stopped working/ran out of battery.
First, remove the screen.
Proceed to remove the first few layers as well.
You’ll eventually come across the perfect mirror for signaling.
Use this to capture the attention of passerby’s.
Even cars, trucks, planes and helicopters.
