Uptime is always 0 on Android 11

Tested on a Samsung Galaxy s10e through termux (not rooted)

Does /proc/uptime exist?

Does /proc/uptime exist?

Yes but it can't be accessed. I've since tested this on a rooted device and the uptime displays properly, so I guess root is required to read that file.

Seems to be an issue with android's tighter permission control with the newer versions.
However, uptime in Termux still seems to work so you could use that to fix the issue.

Why does htop or netstat not work on my device

In order to stop leaking sensitive information via side channels, Android has blocked access to certain interfaces in /proc. This is done for your privacy.

Specifically:

/proc/net/*
/proc/loadavg
/proc/stat
/proc/uptime
/proc/version
/proc/vmstat
And few others.

Restrictions vary between Android OS versions. Thus Android 7 is less restrictive than 8/9/10+. You can use root to bypass them.

Do not open issues in our repositories on this or complain how Google is evil. We do not support such opinion or other Android-specific conspiracy.

I made a quick fix by treating Android as a different OS and using uptime to get the information.
This made me use a lot of awks and greps which I don't know how to avoid while being practical.
For now you can use this patch file and patch pfetch using patch -Np1 -i path/to/patch_file.txt
in the directory where pfetch resides.
fix_android_uptime.txt

EDIT: I have not tested this that much.

Send me example output from the uptime command.

u0_a0@localhost
os     Android 4.14.190-214423334
host   aarch64
kernel 4.14.190-21442333-abSCV414
uptime 24d 13h 23m
memory 4398M / 7459M

I guess changing the os variable could cause some issues with
other information. I only made this patch with the default settings
in mind.

I meant output from uptime verbatim. Apologies.

I'm dumb...
Anyway, it should be the exact same as how Linux would output it.

neofetch works, so i just ripped its code. comment out line 372 (in the get_uptime function under case Linux) and then put

# IFS=. read -r s _ < /proc/uptime
boot=$(date -d"$(uptime -s)" +%s)
now=$(date +%s)
s=$((now - boot))

@sweatymachete lmao thats exactly what i did in my pfetch fork. I just check if /proc/uptime has read permission and if not i do that instead of the normal method.

[Un1q32]

closing this now cuz the repo seems unmaintained

[Un1q32]

@sweatymachete heres the full code if you're interested

if ! [ -r /proc/uptime ] || [ "$PF_FORCEALTUPTIME" -eq 1 ]; then
    boot=$(date -d"$(uptime -s)" +%s)
    now=$(date +%s)
    s=$((now - boot))
else
    IFS=. read -r s _ < /proc/uptime
fi
