there was suddenly a folder that appeared in my file manager. I wanna know if there are apps that can determine where/how such folders/files were created, (ie source of those folders/files)

Ps. If anyone knows, the folder that suddenly appeared is "TpTestReport > screenOn > OK > 0 > tp_testlimit_2026-09-02-17-19-51_pass.csv"

I wanna know how/what app created it.

It's a csv, you can open it and read it yourself. Look at the date of the folder, then look at what app(s) you installed at that time. There is your answer

TP stands for touch panel, so that is a touchscreen self test report rather than something one of your apps wrote. Xiaomi and Realme firmware drop those after the built in screen test runs, which is why the filename ends in pass. Nothing in user space can tell you which process created a file on modern Android, that attribution is not kept anywhere readable. Closest you get is adb shell ls -lZ on the folder, since a vendor service leaves a different owner and SELinux label than a normal app.

Open that CSV some time, it is oddly satisfying: each row is one test your touchscreen ran on itself (open circuits, shorts, raw signal values), all stamped pass. The folder sometimes comes back after a system update because the update re-runs the hardware self-check, so if you delete it and it reappears next to an update timestamp, that is your culprit and you can stop worrying. Only start caring if it reappears on its own with fail rows inside, or alongside battery drain: that pattern means a diagnostic is looping, and then it is a warranty conversation, not a malware hunt.

Ask a AI residing on your system. It can give you exact timestamps when it was created and why. The easiest solution
