Extended battery isues

[bones420la]

Anyone else with an extended battery get reboots if you tap on the bottom of the phone? Its like my battery doesn't fit perfect and any kind of jerk makes it restart. Happens on all ROMs. Easy way to reboot. But annoying when not wanted

It's not the right way to fix it (that would be redesigning the battery or the cover) but putting a piece of paper (as many thicknesses as it needs) between the bottom of the battery and the case would probably keep the phone from rebooting.
