BusyBox v1.21.1-Stericson (2013-09-26 14:33:26 BST) multi-call binary.

Usage: find [PATH]... [OPTIONS] [ACTIONS]

Search for files and perform actions on them.

First failed action stops processing of current file.

Defaults: PATH is current directory, action is '-print'

-follow Follow symlinks

-xdev Don't descend directories on other filesystems

-maxdepth N Descend at most N levels. -maxdepth 0 applies

actions to command line arguments only

-mindepth N Don't act on first N levels

-depth Act on directory *after* traversing it

Actions:

( ACTIONS ) Group actions for -o / -a

! ACT Invert ACT's success/failure

ACT1 [-a] ACT2 If ACT1 fails, stop, else do ACT2

ACT1 -o ACT2 If ACT1 succeeds, stop, else do ACT2 Note: -a has higher priority than -o -name PATTERN Match file name (w/o directory name) to PATTERN

-iname PATTERN Case insensitive -name

-path PATTERN Match path to PATTERN

-ipath PATTERN Case insensitive -path

-regex PATTERN Match path to regex PATTERN

-type X File type is X (one of: f,d,l,b,c,...)

-perm MASK At least one mask bit (+MASK), all bits (-MASK),

or exactly MASK bits are set in file's mode

-mtime DAYS mtime is greater than (+N), less than (-N),

or exactly N days in the past

-mmin MINS mtime is greater than (+N), less than (-N),

or exactly N minutes in the past

-newer FILE mtime is more recent than FILE's

-inum N File has inode number N

-user NAME/ID File is owned by given user

-group NAME/ID File is owned by given group

-size N[bck] File size is N (c:bytes,k:kbytes,b:512 bytes(def.))

+/-N: file size is bigger/smaller than N

-links N Number of links is greater than (+N), less than (-N),

or exactly N

-prune If current file is directory, don't descend into it

If none of the following actions is specified, -print is assumed

-print Print file name

-print0 Print file name, NUL terminated

-exec CMD ARG ; Run CMD with all instances of {} replaced by

file name. Fails if CMD exits with nonzero

-delete Delete current file/directory. Turns on -depth option

That is what i get, for the life of me i can't figure out if that means i have it or i don't. "On the Thread it says To increase stability on Galaxy S4 and other Adreno 3xx devices with driver v14, you need to root and run the following commands on the device as root."

So I'm assuming i require all of them to work in order for any difference. Certain sites list the I337m varient as one of which supports Open Gl ES 3 so i assume it would work :(
