I have my cell phone set to vibrate at work. I keep it on my desk, in my peripheral vision so I can either see the screen light up, or hear/feel a weak vibration in case I'm staring too hard into my monitor and don't notice the screen.
My last phone was great. The vibration was nice and soft. Noticeable by me 95% of the time, and unlikely to go beyond my cubicle. If I did happen to miss the vibrate, it had a neat LED that kept blinking. I had the phone on a small notepad which helped dampen the vibration noise across the desk.
On my new phone (Samsung Galaxy J7), the vibrate is loud, even in a case and on the notepad (which helps, but negligibly. A small paperback book has proven a little better, but I don't think much more will help). I'm pretty sure it's able to be heard over my cubicle walls, using the same method as with my previous phone. Unfortunately, this new phone does not have a notification LED so I've resorted to an app to turn the screen on when I get a notification. However, I may still miss this when concentrating on work as it only stays on for ~5-10sec. So a soft vibrate is even more desirable in case I don't notice the screen display and there is no LED to continuously remind me.
I do not want to keep my phone in my pocket as I obviously cannot see the screen, cannot always feel it vibrate, and it's a hassle to bring it in and out every time I just need to check something or respond to a text. Is there a way to muffle my phone, yet keep it on the surface of my desk around me?
