I'm currently facing this issue: after the ColorOS 12 update on my OPPO find X3 lite, my phone was showing the warning of flash memory full (128 GB). Even removing files, cache, apps and other stuff, after very little time it was showing the warning again.

Long story short, I found that the system is creating multiple copies of the same folder under the path "system/proc/12566/task", there are currently 98 folders using roughly 1,3 GB each.

Is it a system bug? Should I try to remove these folders? Anyone's already faced this issue by chance?

  • /system/proc is not a real folder, therefore it occupies no space on flash. All the content is just data generated on-the-fly by the Linux kernel. tldp.org/LDP/Linux-Filesystem-Hierarchy/html/proc.html BTW: The term "memory" is ambiguous as it can refer to RAM memory or Flash memory. As there is no Android phone with 128GB RAM you seem to refer to flash memory, I have corrected that and the wrong RAM tag.

  • Thank you for the reply Robert, and thank you for the correction, yeah I definitely meant ROM memory (probably the ram tag has been autoadded). Does that mean that I can try to delete that folders?

    there is only one writeable partition so the warning concerns /data only (even if it's named "System")

    Rooting the device would eliminate your requirement for storage analysis now, because in the rooting process a factory reset is performed so all data would be gone...

    /proc, /sys etc. are kernel's virtual filesystems which reside in RAM. And they take very small amount of RAM - not more than a few MBs. Relevant details here. Also related: How disk space is used on Android device?. Apr 24, 2022 at 16:27
