'Migrator' folder gets created automatically - OnePlus 5 Questions & Answers

Hi fellow users,
I am facing an issue where a folder by the name 'migrator' is getting created, at random timings in the sdcard folder.
This started happening around 6 months ago and wasn't too much of problem and I would just delete the folder. It would then be recreated at a later date. Recently, the phone is running out of space and has been slowing down the phone while it is gets created in the background.
I have tried deleting most applications one at a time to find any app that causes the issue, but haven't been successful in finding the cause.
I am rooted with magisk and currently on Oxygen OS 9.0.4
I would appreciate any help to find the root cause and fix the issue.
Thanks in advance!

Looks like you used migration apk (https://play.google.com/store/apps/...pcampaignid=APPU_1_JmCVX6mSINDDz7sPyr-f2A0)to save the data file , just disable the migration helper apk from settings

Thanks to $aur0n for Urukdroid OS

Seeing as I can't post in the developers section I would like to thank $aur0n and the rest of the devs for the latest version of Urukdroid 1.6RC4 Started with UD1.5 last Thursday. Currently running on my A70-8 it appears to be running smoothly. I installed to internal memory with basic partition resize. I am sure it is not optimized for best performance but I consider myself lucky I didn't brick the device.
I found the simply dropping the update file into the data/backup folder (from my Ubuntu 11.04 laptop) did not work for some reason. So, from my Win7 computer at work I dropped the update file in a "download" folder so I could find it, then after dismounting I used File Expert with su permission to move the file to the data/backup folder. Lo and behold the update process started automatically.
I had an issue as I was muddling through from 1.5 to 1.6RC2 where something stopped the google services framework which resulted in a very long boot cycle and error messages. I finally found the entry in applications and I believe a clear data fixed the issue. During this incident I lost my tunein radio app and any attempt to reinstall results in some sort of out-of-memory error stating that the app can not be viewed. Other apps install just fine. I think there is an internal problem with the tunein app.
Anyway, I have been using the A70 a bit more and the battery seems to be lasting as well as it did back on 2.1.8.
Thanks again.
+1! Install was easy, tablet runs smoothly. Thank you to all involved!

Insufficient Storage Available..

Hey guys I've been browsing around simply everywhere trying to find a fix to my issue but haven't been able to so I thought I might post on here to see if I could get some help.
Simply put, I downloaded luckypatcher a fair while ago and tried removing some adverts as well as trying to apply a patch to an application I got, in doing so I believe I may have screwed my phone up because now I can't install updates from most of my applications and some applications cannot be installed at all and I'm basically screwed with no fix at all for myself. Along with that I have 1.8 gigs of free space left so it can't be the issue of storage and I've already tried looking in the data/app-libs folder through root explorer but there isn't one nor any odex files of any sorts, also tried fixing it through lucky patcher to by fixing the permissions in the troubleshoot menu to no avail.. any ideas?
Thanks! -zeksta

No Internet connection possible (Wifi or mobile) after the deinstallation of AdAway

Hello XDA Assist Team,
A few days ago I installed AdAway (via F-Droid) to increase mobile surfing speed. Now I got the problem that while using Wifi, suddenly every app had a 10-15 seconds delay before actually starting to download/ starting to load the web page etc. Once "getting a firm grip" on the connection, the download speed was fine as usual (120 mbit/s). This problem did occur on every app while using wifi, but not while using mobile internet.
So I uninstalled AdAway. Now no application can access the internet. Regardless of wifi or mobile internet, no application managed to access the internet since the deinstallation.
The only host files in the /etc/host folder seems to be the localhost on "127.0.0.1" and another localhost with "::1" . At least that's what the Hosts Editor app said. I installed it via USB to check on the host file.
My system:
Oneplus Two, Oxygen OS 3 (Android 6.0.1), rooted
installed were AFWall+ and Xprivacy. I deactivated, then deinstalled them to make sure they won't interfere. The only other App I installed recently is Cerberus. Except for devouring my battery alive, it did not have any negative effects I could observe.
I tried searching the Unofficial AdAway Thread, but I was discouraged by the 600+ pages. I tried, but didn't didn't find anything useful. I posted my question there as well, but got no reply.
I don't have many skills regarding Android. I installed the OS, xposed framework etc. by closely following the instructions given here on XDA. I have a basic understanding on how to use all these applications but I don't know much about what happens behind the UI. I would really appreciate if you could help me out here and point me in the right direction, prefereably without having to nuke my OS. My last Nandroid backup is about 2 months old, unfortunately.
With kind regards,
Fennec
Edit: My progress:
1. I found a tutorial of how to find and delete the hosts file (http://forum.xda-developers.com/showthread.php?t=2717261) . It was stated that android would rebuild the missing file on reboot. That was not the case. Now in /system/etc there is no "hosts" file and my Internet still does not work. Hope that helps. I tried googling to find an untouched hosts file that I could copy into the folder, was not lucky yet.
2. Found a hosts file here: http://forum.xda-developers.com/galaxy-s2/help/hosts-file-missing-to-t2276818 . Copied it into the folder. Did not work. Help.
Please help me out.
Solved!
Writing down the facts I realized that I haven't tried disabling cerberus yet. I don't know why uninstalling adaway triggered the internet problem but Cerberus seems to have been the cause. It ran for 2 weeks without problem. Now my internet is free again. Either the deinstallation triggered the problem or it was a very nasty coincidence, coinciding with cerberus making trouble. Or maybe cerberus didn't like the system files being tinkered with and decided to lock a potential remote attacker out.

"files" app doesn't start anymore

Hi,
Since a couple of weeks now every time an app tries to invoke the "files" app to allow picking a file or selecting a destination I see the files app appearing for a fraction of a second, but then seems to die or get terminated.
Didn't change anything since a while on my op2, so far I haven't figured out what happened at a certain point to cause this.
Anyone else ran into this problem? Any idea how to fix it? I tried to clear data and cache of the files app, force stop, rebooting, restoring a backup wit titanium backup. No change.
Rooted op2 with latest oxygen os (3.0.2)
ok I sort of "solved" the problem by disabling the "files" app from TB -- so now I'm given the choice of picking another file manager.
For me it was the Box app that somehow made my Files Manager app crash. I removed it and it is back to functional.

How to disable batt_health process in MotoG4 RR

Hi,
This is related to a previous thread where internal memory gets full, which was solved temporarily.
https://forum.xda-developers.com/moto-g4-plus/help/rr5-8-4-athene-internal-memory-filled-t3678840
I am using
[ROM][OFFICIAL] Resurrection Remix v5.8.5 [7.1.2_r29][XT16xx][athene] + Magisk + ElementalX on Moto G4 Plus with 128 GB SD card as adopted storage.
The internal memory was getting full within a week, and with the help of suggestions received, I located that /data/power_supply_logger had .csv log files which were 20GB+ in size. So I deleted them and solved the problem at the time.
Then it repeated in a week I had the same issue. the log files grow about 2 MB every minute. I removed write permissions to the folder and deleted the file.
I noticed that since I removed the permissions to write, the battery life really got longer and the phone also charges much quickly now. Some users pointed out that battery was charging slowly in RR - I faced that problem too and it looks like has gone away. I would like to make it a bit cleaner - a process making an attempt to write every minute and failing is got a good work around.
Using AppsSD I found that /system/bin/batt_health running as mot_pwric user is attempting to write every minute and now that the permission is removed the attempt is failing.
Is there a way I can disable this process - it is not listed in Apps or System apps.
Or if anyone knows how to disable logging by batt_health, that would be better.
Thanks

Maybe some of your apps are logging there?! I have this folder too, but empty.
/system/bin/batt_health running as mot_pwric user is the process logging it. How to disable this process - or if it is spawned by an app, how to locate the parent app.

My suggestion: Just install the rom and gapps mini/pico or beans mini and see if it logs again. If not: install ONE of your 3rd party apps, see if it happens again. If not, install the next one and so on.
Maybe you have switched something on in Rom settings?

I too have this folder and is showing 1.01mb in size.
I cut out read acces to batt_health and it seems nothing has changed.
Also i search folders for battery stats and all are nrml to me.
All of them combined also im not getting more than 10+mbs.
Idk what u have been using or any particular reason for you
I'll suggest clean flash your rom. Use verified gapps and restore backup of apps only and not data. If and if only you need that data restore it.
Use device for 3 to 4 days and see if problem exist.
OK. I will try these suggestions and see if goes away.
