I recently purchased a Pantech Burst Android phone. It’s a nice budget phone with LTE capability. When I set it up initially, I noticed a strange thing about it. I disabled mobile data at home because I have Wifi access. However, the mobile data feature got enabled automatically when the phone woke from sleep mode.
The first thing I did was to contact Pantech support, but they only suggested that I reset the phone. A factory reset would reset the phone and erase all apps and customization, which meant that all the works I did would be lost. Before doing that, I tried to find a solution that would still retain the customization and files.
An online article pointed the right direction for me to solve the problem. This is the quote from the article.
Apps need a special permission to turn on or off mobile data. There’s no built-in way to search for apps that use a particular permission, but you can look at the list of apps in Settings → Apps. In the “downloaded” list, if you click on a suspect app, you can see what permissions it uses. The permission you’re looking for is “change network connectivity“. Any app with that permission might be connecting or disconnecting networks. If you found one in the “downloaded” list, and you don’t think it should be allowed to do that, there’s a button to uninstall it.
You can also see what permissions each app wants before you install it, in the Play Store’s install screen.
I followed the directions to check my downloaded apps. There were a lot of apps to check. Fortunately, I found it within just a few tries. The culprit for this problem was the app Battery Defender. I have this app on my HTC One X and it works beautifully, but apparently it does not work properly with a Pantech Burst. After I uninstalled the Battery Defender app, my phone does not enable mobile data automatically any more. I have included a screenshot of the permissions. The specific setting is under SYSTEM TOOLS section.
