I have an Iphonne 4 (not 4s) with the problem of first hanging and then rebooting when I swipe the silder on the scren.
1. I have reflashed to latest version 6.1.3 (tried with 6.1.2 and 6.1.0 too)
2. If i keep pressing the power button, i can turn off the phone normally.
3. If i press the "i" info icon, it showsme the iccid.
4. I changed the battery
5. I changed the whole screen too.
6. Sometimes it takes alot of time on booting (apple logo).
The only case when it restart is that when i swipe the slider, it hits the right most end, hangs for a second or two and restart.
Please help me in this regard.
