Hi,
Under Phone>Settings what are "long tones"?
Thanks,
yeto
Some older phone systems are somewhat slow and can't recognize the short, fast key tones. The long tones just slow things down to allow the system to process the key tones.
OP is talking about WP8 (I assume) so it's a pretty new system unless by system you mean a hardware? But again most hardware with WP8 is new so can do short and long tones. Unless there is some accessibility setting turned on for the OP.
