Defects
- Some users have reported that 2 GB MicroSD cards, particularly those from Kingston, are not detected by the Samsung Blast, despite functioning correctly in other devices. Cards from Sandisk and other manufacturers do not appear to have this issue.
- Although not a hardware fault, the phone’s call volume is notably low; this can be mitigated by utilizing the included hands-free accessory.
- An unofficial workaround to increase call volume exists but should be applied cautiously: Samsung Blast - Increasing Call Volume
- Additionally, the microphone is highly sensitive to any physical contact with the phone, causing audio dropouts for the person on the receiving end even with slight movements.
