I have a Jiayu G3S android phone. Its system is a rooted Android version 4.2.1.
I've noticed that a folder called "mtklog" on my SDCARD was getting full with files (log files, I guess) until there was no empty space left.
So I learned on the internet that there is a "MtkLogger" app. This app is accessible via the "Engineer mode" (or some MobileUncleTools app of sorts).
The solution found on internet was to check the "/etc/mtklog-config.prop" file on my cellphone.
I looked into it, and indeed it exists on my phone. It contains some tags like
The solution guided to set all to false. Much to my surprise, all of them were already set to false.
All the logs were disabled already.
(Another kind of line referred to was
max log size=300, and I've already changed it to 0 and 1 with no effect)
After lots of tests and research, I opened the MTKLogger app, which I had never done before. I had never seen the app screen. It allows to log events of 3 types (network, disk and cpu).
Ever since, this app opens on startup with all logging options set to on. It even started appearing on running process accused by the terminal.
Now, when that happens, I open the app via the notification, and use the options to STOP all logs and Delete all logs.
But when that happens (That is, the MTKLOGGER is logging and showing me it is logging), the log files go to "SDCARD/mtklog/mdlog" or "SDCARD/mtklog/netlog". These folders refers to the different log types I mentioned earlier.
What is strange is that none of these is the folder that originally bothered me. (i.e. "sdcard/mtklog/aee_exp") And this folder keeps getting filled even with mtklogger not logging anything. So now I have 2 problems: 1) MtkLogger keeps opening by himself, showing on the notification bar, with all logs enabled. 2) I still haven't found out the cause for the aeeexp folder to get filled. My guess is that another app is using it.
I have a Terminal Emulator app (with busybox commands installed).
Here's what I've already tried:
I've tried to create a file with the same name of the folder, so whatever is trying to write there, won't be able to. With that, all the logs went directly to internal storage. (Didn't work well and I gave up on this approach) When I cleaned the internal storage, I cleared some *.zip files with random numbers as name.
I've tried to delete "/system/app/mtklogger.apk" and all the mtklog files that appeared as a find result on terminal. I've tried to check running processes on terminal but no logging one appeared to me. (The only one is Mtklogger, with started to run only after I opened it for the first time) Is there a way to check what app/process is writing on that folder? How can I really unninstall the mtlogger app once and for all? What files should I delete? It has no option on How can I investigate further on this?
I'm sorry for the long text and story-like question, I just couldn't sort clearly what informations would be useful or not.
