[Samsung Epic 4G Touch] neverends:
UPDATE (SO FAR CONFIRMED BY evoholik, neverends, Qosmokid, kanekz)

evoholik pointed out that if after making a phone call, you hit the end button, and wait for the dialer to exit the call screen by itself, your notifications will remain active. However, if you hit end & home OR end & back OR end & power, then your notifications will disappear.

As I mentioned before I never lost notifications but being paranoid because of a past incident, I always wait for my phone call to hang up prior to putting my phone away - this is probably why I never lost my notifications. So after reading evoholik's post I tried this and noticed that if I did any of the above actions I too, lost my notifications.

So here is the next step....

Can a few people who experience this loss try rebooting, confirm you have notifications, make a call, hit end and wait for the call screen to disappear by itself and check to see if you have notification after the call. The try any of the above three button combos and see if it triggers a loss of notification. (As I mentioned this was the case with my phone)

Also if a few people have the time - please try using a third party dialer and let us know if the problem persists....

TO THE XDA DEVELOPERS:

:)

I don't know much about programing and was hoping for your help... I have three questions...

1. Is it possible that the loss of notification is due to the dialer hanging/freezing/running in the background?

2. Is there a way to check if using the above button combinations can trigger the dialer to hang?

3. If this is the case, can we force the program to shut down by modifying the dialer APK OR using the kill processes feature under the developers section of setting to force the dialer to shut down appropriately?

As you may have read many people are having issues with their notification tones not working. I am hoping this thread will help narrow the problem down. After my own testing I have come to the following conclusion...

The notification tones that come with ICS will work fine for me... If you have custom tones your notification tones may drop out after making a call, or receiving a text mid call. There are other situations reported as well.

Some reported fixes: (Try these and post which worked for you)

- Removing google voice fixes the problem

- Removing google voice integration solves the problem

- A reboot fixes the problem

- Installing a secondary notifier like the ones listed below solves the problem

- Using Go Sms resolves the problem - only for SMS/MMS

As far as my set up - I am running Calk's rooted FC18 with FC18 modem, and FC18 REPACKED kernel.

I tested many scenarios and my notification sounds seemed to work fine. [strikeHowever I realized that I am only using the stock tones. I then tested my Facebook notification which is installed once you install Facebook and not a part of the ROM and realized that although i received the notification at the top there was no sound. I then switched the tone from Facebook Pop to S_opener.ogg (an included notification sound) and realized it began to work.

Next I substitute a custom tone for my SMS notification and tried calling then receiving a text and lost the sound.

If you are having problems with notification sounds disappearing please check to see if you are using a custom tone... if you are then try one of these as a resubstitute and report your results here
