Well for me it's messed up music playback. Nokia Music is fine but if I play anything saved on the phone then even on full volume I have to put my ear next to the speakers to make anything out?!?!?
I think the volume levels on the L920 is terrible. I had the Titan before this phone and normally it was set around 19 where the L920 has to be at full max at 30 and is still too low. I'm still using the same headphones. Also I have tried the new update and think it's got worse.
Got the audio update, and noticed the new volume levelling feature, can't wait to try it. I get really annoyed with songs being at different volume levels.
