Lg optimus s black can't change the notification

you can turn your volume down which will then only work the vibrate motor or in settings go to "sound" change sound mode to either mute or vibrate instead of sound. you can set vibration intensity to low for notifications. also under "ring and notifications" change your notification tone silent at the top of the list.

I hope this was useful

Ur lcd for Ur screen could be out . If Ur screen is black and everything else works fine its a good possibility

Strange. I would try resetting your iPhone. Hold down the home and power buttons until it powers off. It should start up automatically but if not just press the power button. This has worked for me in the past when my iPhone has acted strangely.
Don't worry about a reset or hard reboot. You won't lose any data or settings.

If it's a GSM model and you need a network code, you can use the following service (all LG models are supported): http://www.fastgsm.com/en/lg/lg/optimus-black-p970/unlock-code-usim-locked

This is a feature not available by default you may download a third party application that does exactly that (and then some).
I recommend "Ringdroid.
1. Launch the Market application
2. Search for "Ringdroid"
3. Download and Install the app to begin using it.
4. Launch the app and begin browsing the songs on your SD card that you'd like to set as your ringtone.
5. Edit the Song and Save it. After saving your edit, you will be asked to set it to a specific contact or as your default ringer.
Enjoy

Hi,
It's prety simple to unlock LG Optimus Black Smart phones, first you need to know which network provider you bought that phones then you asking them how to get LG Optimus Black Unlock Code. Usually they will asking you about your phone invoice data to make sure you bought that phones from them and you must prepared some administration process. But if you want save more times, you can bought LG Unlock Codes directly from third parties websites and you will get instant unlock code in a couple of minutes.

If you want to choose a tone from the available message tones, Click start->settings->sounds and notifications->notification. Under message tone select from one of the presets. If you want to use a custom made tone then you should first covert it to wave file and transfer to the phone.

Feel free to post back if you need more help.
