i have no financial relationship, nor do i have any financial gain in posting this recommendation for the "LED flash and vibrate notifier" app. if you doubt me, which is fine, just look at my other post history. no other app does exactly what "LED flash and vibrate notifier" does. IF I AM WRONG, PLEASE POST YOUR RECOMMENDATION! anyway, my friend has LED camera flash notification on his new iPhone 4s for only incoming calls which made me very, very jealous, but this app does much more. likely, you hate the fact the sgs2 does NOT send out multiple reminder tones like the captivate did at least a few times for missed calls, etc. also, the notification tone volume even on the loudest notification ringtone is too low to hear, and worthless. this app is highly programmable and has an easy user interface (ui) for using the LED to flash/vibrate for incoming calls, new voice mails, new text messages, missed calls (even with no voice mail being left), and i think new email. i have not tested it for new email. the developer fixed a few bugs i found on the sgs2, and now perfect, in my opinion. well worth the $0.99, and minimal permissions. EDIT 12/10/2011: because user riskr here brought up the idea of it also vibrating, i passed this idea along AND IT NOW ALSO VIBRATES/FLASHES (programmable) FOR UP TO 2 HOURS (programmable). i spent an hour looking for an app which did just what i mentioned above, nothing more, nothing less. i just wanted the LED flash/vibrate for missed or new items (calls, texts, voice mails). i use the flash and vibrate together. if you ever have a hard time hearing your phone in your car at night OR day with the window down or the music on, just flip the phone over, and you can see it flash when someone calls. since i smoke, i always have the windows down and music on, so for me, this is very handy. maybe this will save people time finding a cool, new app which is very useful every day. ALSO EXCELLENT WHEN YOUR PHONE IS IN SILENT AND/OR VIBRATE MODE TO NEVER MISS A NOTIFICATION BECAUSE IT REPEATS UP TO 2 HOURS!! market link via your pc: https://market.android.com/details?...wsMSwyLDEsImNvbS5ncnJ6enouZmxhc2hfbm90aWZ5Il0.
