All but ready to return it.
I use my phone on vibrate all the time because of meetings and obviously if vibrate is not strong enough to get my attention the majority of the time then the phone isn't usable in that fashion. I know I cannot simply expect myself to remember to put the phone on silent every time someone important enters my office or even when I go to a meeting. I consider it unacceptable to have my phone go off in a meeting with a customer or someone in the management team.
There are some vibration patterns that seem more strident than the default, if not, I am likely to return the phone. Perhaps I can just keep in on silent and check it much more often, but that is less than appealing to me. Does anyone else have this issue?
