When you are talking to someone, you can increase or decrease the incoming voice through Volume key. Press the volume Up to increase volume.
Remember volume will increase or decrease only if you ore on a call.

My volume keeps increasing and Problem with the LG KU990 Viewty my volume keeps increasing and decreasing when i am on a calli have a lg ku990

That sounds like you have a power supply fault.
If the mains fuse has blown on the chassis, check the Switch Mode Chopper Transistor and dry joints around the transformers.
Be careful replacing the chassis in the case as the join gives problems!
Hope this helps.

There are 2 types of volume in your nokia phone that you can increase or decrease.

The first one is the ring tone volume. You can either increase or decrease your ring tone volume by pressing the menu key then go to settings, go to profile, select any desired profile go to personalise go to ringing volume, then increase or decrease by using the navigation button to the right or left.

The second way is to increase or decrease the volume of the speaker of your phone which i think is the cause of your question (this volume enables you to hear clear and loud the person on the other phone). You increase or decrease the volume by making a call, as soon as the call starts ringing, press the navigation key to right to increase the volume or to the left to decrease the volume.

bro my probleme ako may b+ pero wlang tao tapos maliit lang hindi naman sira ang vertical IC

I have Sanyo TV. This problem started after I got into a sub menu with choices of volume lock and channel lock. I accidently set it the volume lock to ON. I could not go to that menu again. It seems that this TV has the feature of securing the volume so that the kids can't change it. Any way to go to the locks sub menu?
