  5. Hi, I have a Zenfone 5 running on Android KitKat 4.4.2. Ever since I got this phone around 2 months ago, Android OS background data usage has been absurdly high. It’s now at 48MB while the total usage is at 80MB (includes Android OS consumption). I’ve already disabled syncing for, I believe, everything, turned off location setting, turned off backup and restore, turned off check for updates. I’ve read a lot of articles on Google on possible cause. I’ve also restored factory settings but none of these fixed the problem. Would you know what could be causing this? Or how I can troubleshoot? Thanks 🙂

  8. Hi dear friends,
    Last night after I connected to the home wifi, a reminder said that an update is ready (as it happened before), I accept that and after shutting down, it normally updated to android 4.4.2. When it started again, everything was ok except wifi. Although I turn it on, but unfortunately it can’t find any ssid name while other mobile and tablets connects normally.
    I tried a lot and so did factory reset, I lost everything but the wifi problem not solved.
    I’m looking forward to hearing from you ASAP.
    Believe me, it’s a very urgent condition.
