KIK chat on IOS

Hi guys!
I have download Kik for both android and IOS . However, the issue is when I mod this app and run it in both two devices: samsung and apple, it gives me different experience in typing messengers and sending pictures.How can I fix this problem?
p/s: for android, I download two versions from Google play and from here http://choilieng.com/apk-on-pc/kik.android.apk.
for IOS : https://itunes.apple.com/us/app/kik/id357218860?mt=8.
Can you help me give the name of this problem? I appreciate any idea or suggestion. Thank you in advance.
