mobile

I recently moved from a Galaxy Note 2 to this great looking phone. However I noticed that it is using a lot more data than my previous device. Upon looking into my device's data using with an app called 'Callistics', i noticed that an app called "MMI TEST 2" was on number one of my data usage apps (about 60Mb daily) next to Ingress. Using a different data usage tracking app (My Data Manager) I noticed that an app called "Keyguard" was using the same ammount of data as MMI TEST 2. Perhaps these are one and the same thing? But why would a Keyguard app or MMI TEST 2 app use up so much mobile data? What is it sending or receiving? I have no way of finding this out. All I managed to figure out was that these were pre installed system apps. I asked Huawei support on this but they are yet to get back to me on these apps. Still, it smells fishy. I cannot help but being suspicious about the behaviour of these apps since my last device running the same android version 4.4.2 did not have this issue, so it's not something that the system 'needs' in order to run. Can someone here verify this? Or better yet, tell me what these apps are actually doing? Thanks!
