  • There have been reports of 2 GB MicroSD cards (specifically Kingston) not being recognized by the Samsung Blast while working in other devices. However, Sandisk and other brands seem to work fine.
  • While not technically a defect, the Samsung Blast has a low call volume which is easily solved by using the hands-free accessory that comes with the phone.
  • Unofficial fix for low call volume. Use at own risk. Samsung Blast - Increasing Call Volume
  • Also, the microphone is ultra-sensitive to any contact made to the phone. Even slightly moving the phone can cause the user to cut out to the receiving person.
