It's probably a defect in the device firmware. Cheaper phones often have less effort put into making sure the firmware is perfect. In that case, a new firmware would fix the problem, though again, cheaper phones are less likely to have a firmware update available and less likely to have a custom ROM development community. Even so, it's worth checking with the manufacturer.

If there are no firmware updates available, your only option is a better phone, from a manufacturer who's willing to spend the money getting the system integration right.
