My phone seems to be suddenly uploading GBs of data at speed of 8+Mbps. I cannot identify which direction app is doing this. But systems network indicator seems to show that is uploading data. Just not which app.
I even tried force stopping my frequently used apps while this happens to see if data upload stops. But i haven't been able to identify which app is the culprit.
Sometime the speed of upload reaches 20mbps and makes my phone stutter. What i can do find out enough app/process is transferring so much data.
I also tried installing https://play.google.com/store/apps/details?id=com.drnoob.datamonitor
It also shows high speed of data transfer being happening. But it cannot identify which app is doing it. App specific usage stays low.
I have access to adb tools, root, as well as termux if that matters.
I tried using nethogs in termux but it didn't detect the process causing high speed data transfer.
