Jasjar - Voice cracks too much

Sometimes these devices get hot.So try switching it off and remove the battery as well as the sime and wait than for a while.Do than a hard reset.I must warn to first back up important information from the device as once you do a hard reset.The device will be restored to the orginal factory settings and all data will be lost.Try this and see.I had a problem with the device ringing very shortly like about three to four rings and than it just it would just cut off.People would complain about me not answering the phone.But it was not me but the device not giving me enough time to answer.So I did a hard reset and it is working fine ....for now.I'll see what happeneds.So try this and see if this is a problem with all your calls than have the software checked out.
