Hi!
I have 2 cellphones, Samsung Galaxy S4 mini Duos whit Android Jellybean 4.2.2

1. Description Cell No.1
PDA: I9192UBUBMK4
CSC: I9192UUBBMK2
MODEM: I9192UBUBMK4
Estado de SELinux, enforcing, SEPF_GT-I9192_4.2.2_0002

2. Description Cell No.2
PDA: I9192UBUBMK4
CSC: I9192UUBBMK2
MODEM: I9192UBUBMK4
Estado de SELinux, enforcing, SEPF_GT-I9192_4.2.2_0021

The problem is the cellphone No.1, the battery is discharged very quickly,
before sleep is at 100% and when I wake up is at 60%, about 8 hours standby.

In contrast, the cell number 2, the battery is at 100% and when I wake up is at 96%. about 8 hours standby. (This cellphone is perfect).

The only defirencia I see between cell 1 and 2 is the SELinux, the first ending with 0002 (the problem) and the second ends with 0021 (OK)

How can I change the SELinux in the cell No.1 for this in _0021?
These endings mean?

sorry for my English.
Thanks.!
