[SOLVED] Chinese Phone stealing my information/bandwidth?

[ihave400houses]

Hi, I own a Xiaomi Redmi Note 4 that I purchased from banggood.com. I know that people say these Chinese branded phones have the potential to have spyware on them since it has a English ROM loaded on it before it is sent out after purchase

Whenever I connect the phone to my home network everything on the network slows right down. I got an app on the phone that helps measure speeds on my network. Whenever i check the download/upload rate, the phone appears to be using 100% of my internets upload bandwidth. The app also tells me what app on my phone is using the bandwidth, which was 1 app. I deleted the app using the upload and then another app I had said it was using all of the upload bandwidth. I did this once more and then another app went to using 100% of my upload.

This only happens when I connect to my home network, It does not happen when I connect to my mobile network.

I am starting a new job today which requires an android phone and an app that the company uses to get pick lists. I am worried that me connecting to their network will cause issues.

I am looking into how to install a new ROM onto my phone but do not have enough time to do this before I start my new job today.

Has anyone else had issues like this? Any information or advice would be really appreciated.

Which that "app" would be it?

You have plenty of options, like stock rom install ; root phone and uninstall/block app ; install custom rom.
