I made a post earlier this week concerning a vibration that I noticed in my new Samsung Galaxy S4. I'm writing this to warn potential buyers of this strange effect.
Initial post: http://linustechtips...s/?hl=potential
When I remove the S4 from my pocket and transfer it from hand to hand, or if I'm playing a game and I tap the screen a bit harder than usual, the entire phone vibrates in my hand. It feels much like the vibration function in the phone, and it is. The vibrating motor in the S4 doesn't appear to lock up, so any time you jar the phone you can feel it resonate in your hand.
To be clear, this is not the motor actually running. This effect persists when the phone is completely powered off.
After some investigation at a local Bell store, I learned that this is the case for all of the S4's that I tested (2 live demos in store). After playing around with the Sony Xperia ZL I found that it also vibrates if dropped onto someones hand from a height above 5cm. I tested the HTC One, and could just slightly feel the vibration- It took a good hit with my finger to produce anything.
I know this is a minor issue, but it really does make the phone feel cheap, and I'm reluctant to use it because of this. I bought a case for it but i'm really concerned about dropping it, as if something is loose directly from the factory then who knows what could happen after a few drops to the ground.
Let me know what you think of this, and to all the current S4 owners, tell me if you can reproduce this effect by doing the following:
1.) Hold the phone in your left hand near the top and tap the back of the phone at the bottom left corner with your finger. This should cause the entire phone to vibrate. I know this is extremely specific, but I seem to inadvertently tap the phone often and it vibrates every time.
2.) Lift the phone a few centimeters above your hand and let it go. When it lands it will begin to vibrate. This is analogous to transferring the phone from hand to hand, which happens often - this phone is HUGE!
