Once or twice a day, I get a full screen nag from the OS asking me to upgrade to Android 7. My phone is working great, so I'm not interested in upgrading as that will likely break and/or change things in ways I'd rather not deal with.

So, how do I prevent the nag screen from appear? Preferably without rooting the phone.

Model: SM-G930U
Android version: 6.0.1
Android security path level: March 1st, 2017

Nag Screen:

  • I believe you can not. These updates are push over the air from the vendor. You can keep clicking on "LATER" if you manage – Ajay S Jun 14 '17 at 18:50
  • By vendor do you mean Samsung or the service provider Republic Wireless? That is what my service provider said. I gave them a polite lecture on respecting customers. – Stephen M -on strike- Jun 14 '17 at 18:54

If the notification is really annoying you, you could get rid of it by performing the suggested method of disabling the process responsible for handling system updates and associated activities named com.wssyncmldm.

Head to Google Play store and grab Package Disabler Pro (Samsung)($1.49 not sure if there is free version, but reviews claim this is worth the bucs)

Open Package Disabler Pro and disable the process/service named com.wssyncmldm and com.sec.android.soagent . This should stop the update notification.

Disclaimer: I am no way associated with the app, and this is just for educational purposes, Information is gathered through research from credible sources.

Edit: Package Disabler Pro 6.3 is recommended, read more here: https://www.reddit.com/r/GalaxyNote7/comments/5bnlcj/i_dont_think_so_verizon/

There's a better way to disable any package by using the adb pm uninstall command.
Note that this will not actually uninstall the app, but will only hide it from the system. Best of all it works on non-rooted devices too!! Enter this from your adb folder:

adb shell pm uninstall -k --user 0 com.wssyncmldm

If you really want to get rid of a lot of Security+OTA nagging, then run the following list of commands. Optionally you can save it in a batch file to make it easier to run. Note: Some packages will fail to uninstall which is fine, since this is a generic uninstall list for various Samsung models.
