I will say this as a fact.

I grew up with the number pad key Nokia type phones and my parents had the ol bricks..

Remember the phenomena of PHANTOM VIBRATION?

Doesn’t seem to happen anymore. Maybe more so of a “phantom dulling”

They had to come out and say it was a placebo phsyco reason you’re anticipating the ring.

No way, you would literally feel your leg VIBRATE often times before a call came on!

All of a sudden phones upgrade, no more “Phantoms”! Gee! I guess we are all just used to it they would say..

I heard that the radiation levels only pass tests because they test them on dummies wearing cases on the OUTSIDE of the pocket, often with thicker padding, not tightly tucked up on your leg..
