I used this link Use Adb to disable Media Server
hoping to permanenenly disable the battery hogging media server process . It did not work Mediaserver still runs on my Android 4.4 Jiayu S3 phone as /system/bin/mediaserver
and I found another just as pricky process called /system/bin/drmserver
which shows up on adb # top
.
So I mounted the /system
in RW mode and removed -x
from them both.
After that I killed the existing processes for these binaries. The phone just froze . After a force restart it will NOT BOOT until I restored the -x
bit again ( restored execute ) .
What do these do . How do I ensure they don't run if they are not needed.
