Issues

microG

Battery Drain

microG fails to register applications to GCM/FCM (Cloud Messaging) if they were installed before microG, but the apps keep trying to register and that causes the battery drain, all apps installed after microG are properly registered.

To fix the battery drain, issue the following shell command as root:

find /data/data/*/shared_prefs -name com.google.android.gms.*.xml -delete

Alternatively, use nutl -r to force un-register all your applications from GCM/FCM (they'll re-register on next start)

microG lacks features

If you use AppOps, PrivacyGuard or the like you have to grant microG GmsCore all permissions. If you prevent some permissions, some apps or features might not work as expected or not at all.

Note: some APIs/features are stubs in microG GmsCore. They exist so that apps don't complain, but they do nothing so there is no benefit to block GmsCore.

permissions not granted on Android 10+

On some ROMs, It might happen that microG (Magisk mode) is not granted the RECEIVE_SMS and ACCESS_BACKGROUND_LOCATION permissions. The fix is to install microG as user-app addtionally to system-app. This is done automatically starting with version 23.0 of NanoDroid (and not required in System Mode installation).

FYI, to do so, issue the following command on-device as root (via adb shell or Termux):

Full package: pm install -r /data/adb/modules/NanoDroid/system/priv-app/GmsCore/GmsCore.apk
microG package: pm install -r /data/adb/modules/NanoDroid_microG/system/priv-app/GmsCore/GmsCore.apk

See microG issue #1100 and microG issue #1100 for background information

Updating microG to (at least) 0.2.7.17455 will fix the issue

Google Play Services are missing

This misleading error message actually means Something is wrong with Play Store.

Ensure as mentioned above you properly setup microG and reboot.

Then, install either Fake Store or Play Store

Grant signature spoofing permission to Fake Store or Play Store
go to System Settings > Apps > Permissions > Signature Spoofing for that
on some ROMs you have to tap on the 3-dot-menu Show System Apps to see Fake Store
or manually using pm grant com.google.gms android.permission.FAKE_PACKAGE_SIGNATURE as root on-device
likewise pm grant com.android.vending android.permission.FAKE_PACKAGE_SIGNATURE for Phonesky

SafetyNet

Note: microG's Droid Guard Helper is currently not able to perform SafetyNet Attestation.

SafetyNet check complain with Google Play Services are missing
- see Google Play Services are missing above
SafetyNet check fails after upgrading Magisk to version 18.0
- go to Magisk Manager > Magisk Hide and activate it for microG DroidGuard Helper
Applications crash during SafetyNet check
- install microG DroidGuard Helper as user-app (required on some ROMs), as root, on-device, issue:
  - pm install -r /system/app/DroidGuard/DroidGuard.apk
  - this is done automatically in Magisk Mode (as of version 20.5)

Play Store

Play Store not opening (error RH-01)

Play Store giving error RH-01
- ensure you rebooted after microG setup
- ensure Play Store has signature spoofing permission
  - go to Settings > Apps > Permissions > Signature Spoofing and grant it
- go to Settings > Apps > Play Store > Permissions and grant at least the Phone and Storage permission
- force close Play Store and open it again

Updating Play support libraries#

Play Store tries to update itself or the Play Services, both updates fail because you have microG and a modified Play Store installed. You can disable the GMSCoreUpdateService service of the Play Store to prevent it from updating.

Can't install split APKs / extra data

several huge applications (mostly games) have a rather small base APK and additional addon-data downloaded, if Play Store fails to install those
- go to Settings > Apps > Play Store > Permissions and grant at least the Phone and Storage permission
- force close Play Store and open it again

Play Store does not show bought apps as bought

If your Play Store doesn't show already bought apps as bought, you need to register the device ID to your Google Account. Doing so will eliminate the "uncertified" status of Play Store and thus will allow you to re-download your already bought apps. Also, remote installations using https://play.google.com will work again afterwards.

Go to microG Settings > Google Device Registration and note the Android ID
Navigate to https://www.google.com/android/uncertified/ and login using your Google Account
Enter the ID shown in microG settings into the Android ID box and tap register
Clean Play Store Cache (Settings > Apps > Play Store > Storage > Clean Cache)
Reboot your device - the status of your bought apps is now restored

Play Store web interface can't install apps on my device

See Play Store does not show bought apps as bought above, same fix.

Push Messages

Apps are not receiving Push messages
- go to microG Settings / Google Cloud Messaging and check if it is connected
- ensure you don't have an adblocker blocking the domain mtalk.google.com it is required for GCM to work
- when using Titanium Backup or OAndBackupX first install the app only (without data) and start it, this will register the app, afterwards restore it's data
- when restoring the ROM from a TWRP backup GCM registration for apps is sometimes broken. You may use the following command to reset GCM/FCM connection(s). App(s) will re-register when launched afterwards:
  - nutl -r APPID (eg.: APPID = com.nianticlabs.pokemongo) or nutl -r (for all applications)
- if you can't make any app registering for Google Cloud Messaging, try the following
  - open the Phone app and dial the following: *#*#2432546#*#* (or *#*#CHECKIN#*#*)

Unified Nlp

Note: unified Nlp has known issues on Android 10+.

unified Nlp is not registered in the system
- some ROMs with native signature spoofing don't look for com.google.android.gms as location provider
- tell the developer (or maintainer) of the ROM to fix this
- some versions of com.qualcomm.location conflict with uNlp, if it's installed and unified Nlp doesn't work, try the following command to get rid of it, as root, on-device:
  - novl -a com.qualcomm.location
unified Nlp is registered in the system, but fails to get location
- issue the following commands as root, on-device:
  - pm grant com.google.android.gms android.permission.ACCESS_FINE_LOCATION
  - pm grant com.google.android.gms android.permission.ACCESS_COARSE_LOCATION
  - for Android 10 and newer, additionally: pm grant com.google.android.gms android.permission.ACCESS_BACKGROUND_LOCATION
- some versions of com.qualcomm.location conflict with uNlp, if it's installed and unified Nlp doesn't work, try the following command to get rid of it, as root, on-device:
  - novl -a com.qualcomm.location
Ichnaea (Mozilla) location backend doesn't provide location
- if you use Blockada, add the location backend to the whitelist
- for any other ad-blocker, whitelist the following domain:
  - https://location.services.mozilla.com

F-Droid

On some ROMs (most noticeably MIUI ROMs), F-Droid can't install applications. This is because F-Droid's Priviledged Extension is not compatible with those ROMs:

Disable it from F-Droid > Settings > Expert Settings > Privileged Extension

Aurora Store / Aurora Droid

If Aurora Store or Aurora Droid can't download/install applications check the following things:
- go to System Settings > Apps > Aurora Store > allow "install unknown apps"
- go to System Settings > Apps > Aurora Droid > allow "install unknown apps"
- go to System Settings > Apps > Aurora Services > allow "install unknown apps"
  - if you use Aurora Services as installation method
- also ensure Storage permission is granted for them

Google Software

Maps doesn't work when installed a second time
- remove your Google Account and re-add it, that'll make Maps work again
- remove traces from previous insallations, like
  - /sdcard/Android/data/com.google.android.apps.maps
  - /data/system/graphicsstats/1559520000000/com.google.android.apps.maps
    - where 1559520000000 is the Maps version, so may differ
Hangouts isn't properly working
- as root, on-device, run the following command:
  - pm disable com.google.android.talk/com.google.android.apps.hangouts.service.NetworkConnectionCheckingService

Other

Alarm Clock not ringing

Due to changes in Android, to ensure your Alarm Clock is actually waking you up, you need Android to ignore battery optimization for it, to do so:
- go to System Settings > Apps > Special Access > Battery Optimization > All Apps
- tap on your Alarm Clock, for example Alarmio and choose don't optimize

Issues with ROM Sup Wizard

Some Stock ROMs do not properly work after first boot since their SetupWizard is disabled by NanoDroid (because it's incompatible with microG)
- check /system/build.prop or /vendor/build.prop if they contain the property ro.setupwizard.mode and change it to (you can do this from TWRP via ADB, with the builtin vi editor)
  - ro.setupwizard.mode=DISABLED
  - in Magisk Mode NanoDroid will do this on it's own using Magisk's resetprop
- if you can access your device via ADB, you can also issue the following command as root, on-device:
  - nanodroid-util --fix-update

Applications crash with Bromite WebView

install Bromite WebView as user-app, as root, on-device, issue:
- pm install -r /system/app/BromiteWebView/BromiteWebView.apk
- this is done automatically in Magisk Mode (as of version 20.5)

ROM lags after applying signature spoofing patch

Some ROMs already have the patch built-in. If you patch those ROMs (again), it results in heavy lags. Recent Patcher versions check whether the ROM has the patch already applied and disallow double-patching

Applications can't access storage / permission issues

if your Applications can't access storage or have other permission issues, do the following:
- from TWRP remove the file /data/system/users/0/runtime-permissons.xml
- or run the following command as root while in ROM: pm reset-permissions
and reboot
