Help/Support [IDA] Trying to modify Agar.io CalculateZoom value.

[Smvueno 1 23]

Hello there folks! 
If you are good at IDA modding i would love to get some help!
I'm trying to figure out how to change the zoom level in Agar.io 1.2.2 for android.

I've extracted libgame.so from the apk.
Opened it in IDA.
Found the CalculateZoom level sub part.
And is now trying to figure out what number to edit and how.

This is the part i am playing around with:

If i change 
LDR R0, [R4,#0xC4]
to 
MOV R0, R7
It becomes crazy zoomed out and craches. 

If i modify it with: 
MOV R0, #0x7D0
It just craches again.

I've also been experimenting with a lot of the other values but they all end up in crash.
Anyone got an idea of how to find the right value?

Thanks on forehand!

Maybe it can be

MOV R0, #1

Idk

LDR R0, [R4, #C4] modify it again and find out where the crash comes from. Then try patching the crash

[Smvueno 1 23]

Seems like the LDR R0, [R4, #C4] is not the key.
It just crashes, sometimes it is small, sometimes normal size and sometimes just crashes with nothing at all there..

[Smvueno 1 23]

I have been sitting here this evening too trying to figure this out.

Seems like that no matter what i change, the size is still the same and it will end up in crash :S

Anyone else who are brave enough to try ?

Are you changed ?

Last I checked, you could change the zoom amount using Flex.

[Alex Popu 0 21]

What is flex ?

Are you know flex alternative for android ?

Don't know if Lucky Patcher is identical to flex.
