How To: Increase Your Samsung Vibrant’s Volume Beyond Full Stormy Beach 17 August, 2010 17 Comments Found this volume mod over at xda-developers posted by bchalk. By default the Samsung Vibrant’s software is set at 88. That leaves a little more room for volume if you so desire. Follow the instructions below if 88 just isn’t quite loud enough for you. WARNING: 100 IS VERY LOUD! Dialer: *#*#197328640#*#*  AUDIO  HANDSET  VOLUME  SRC Speech RX Volume 5_lvl : 88 Menu -> Key Input Change to any number greater than 88 (Max:100) OK Press back to save. Default values: 0_lvl: 63 1_lvl: 68 2_lvl: 73 3_lvl: 78 4_lvl: 83 5_lvl: 88 It will reset after a reboot so be sure to run through it again if you wish to increase the volume level again. There isn’t enough testing done or reports at this time to tell if moving the volume past 88 will damage or blow out your speaker. So as usual if this mod blows out your speaker you are using at your own risk. You can also access AndroidSPIN forums HERE to talk about this MOD.

Mnguyen2903 Do u guys charge anything when i dial ? http://www.ShortSale301.com Jon HAC mode came with the Android 2.2 upgrade I believe, so upgrade and then you should see it. http://www.ShortSale301.com Jon Also w/ 2.2, I think now my email alerts during a call sound the same as a Call Waiting tone. Either that or I miss a ton of calls every time I’m on the phone- but they don’t show up in the Call Log. Very annoying. Anyone know how to change the new email alert tone during a call so it’s different from a call waiting tone? srinivas I don t find HAC mode in call settings , model Samsung galaxy s GT i9003 , I am also facing the same issue incall voice is too low , how can I rectify this lam nguyen OMG , thanks u so much !
