Phone App Issue

Jan 24, 2016
Hi everyone,
I own a Redmi Note 2 Prime with weekly MIUI ver.6.2.25.
Phone app and contacts app no longer opens and all my contacts are lost!!!
If I try to add someone via whatsapp it comes me a odd message box.
I think SElinux is broken but I do not know what to do.
I also have a full backup of the partitions of the 26-3-16

Any help would be apreciated, thanks!
