I am a proud owner of a Samsung Galaxy Y and it stopped beeping when new text messages arrive.
I've tried every setting and even tried a reset factory settings. Nothing helped.
So I wrote an app to do this. Mind you, I did it mostly to solve my own problem.
It's free, there's no GUI and no ads.
If anyone is interested I uploaded it to Google Play at https://forums.androidcentral.com/e.../store/apps/d...falk.falconsms&token=ZMbM1UrT
I've updated to the new 4.0.4 LK3 and so far so good. My Notifications haven't stopped and all seems well. Took 6 months but all is well with the notification issues.
Side note with this new update. They did remove the ability to uninstall the bloatware. This was allowed only in 4.0.3 which now seems to have been an accident. Of course if you skipped 4.0.3 you will no see difference with this issue as it wasn't allowed in gingerbread either.
