same problem here x1033 dual sim model also, first time encounter after 2 month of use but for now regularly.
but i came across may some solution as i not having this problem for last 1 week.
for that u have to change a developer setting under developer option.
Developer options---select runtime--now u see 2 option use dalvik is default one, but this time u need to change to--->>USE ART option
system will ask for reboot
reboot it, will take some time to reboot please have patience .(u can see android upgading on reboot screen)
