Whenever I get a message from WhatsApp (purchased legally), i press the bower button or the home button to show the lock screen and the message preview. Most of the time, when i do this, the phone goes into safe mode and I have to respring. My phone is jailbroken, and I have syslog and crash reporter, so if needed I could post a system log of the crash.
Will this help?
Can anyone help me with the problem?
