I've tried to install various third party apps for SMS/texting (Handcent, Go SMS, etc) for various reasons but I always have the exact same problem with all of them: the vibrate on these apps is EXTREMELY weak. I can barely feel it even if it is in my hands. The stock messaging app vibrates perfectly fine. Other third party apps (i.e. scramble with friends) work perfectly fine with the powerful vibrate. Any help? Can't seem to find anybody else with this issue so maybe its something I'm doing? Thanks, in advance! PS. I have the Samsung-released GB update on my phone.
