A bug has been discovered in Android Oreo which could end up costing you a small fortune.
The bug came to light earlier this week when it was discovered that Android Oreo causes some phones to eat through mobile data, even when they are connected to WiFi.
If you’re a user on a limited data plan, this could end up causing serious problems.
The problem was first spotted by a Reddit user who wrote: “After updating to Oreo last night, I received a huge spike in data usage, all the while being connected to WiFi.
“I contacted support and was told that they are aware of the issue and are working on a fix. In the meantime I have turned off mobile data while at home, so only WiFi is being used.”
Other users then came forward to say they had reported the same issue.
The issue occurs because the Mobile Data Always Active option is enabled by default and the only way of turning it off is to activate Android’s Developer Options.
However, as the Reddit user noted, most users “might not know this was happening, as it hasn’t in the past.”
In order to open Developer Options you need to go to Settings > About Phone > and tap seven times in quick succession.
You can then disable the Mobile Data Always Active in the settings menu of Developer Options.
After the issue was made public, Google has said it is aware of the problem and is working on a fix.
If you are already running Android Oreo you can check how much mobile data your smartphone has been using by swiping down from the top of the screen and tapping on Mobile Data.
