LG K40 Android OS High Data Usage
My phone used 1.34 GB in one morning without me touching it. On the phone I went to: Settings/Network and Internet/Data Manager in order to see what was using all that data. The data was used by Android OS. When I touch the Android OS line in Data Manager the phone tells me that a system app called Font Server used 1.34 GB. When I log in to my ATT account with my laptop the 1.34 GB does not appear to have been charged against my account.
Should I be concerned about this? There are bits and pieces on the internet and in Android Forums about a Font Server Virus. On the other hand, I have noticed that with my LG K40 that software updates are being pushed to the phone without me taking any action to download them. After this incident of high data use I updated the phones software. The problem has not happened again but it has only been a day since the software upgrade.
