I'n trying to uninstall some apps that are clogging up my phone. Such Google Duo, Upday and Speech Services by google. I have uninstalled these apps, but I keep getting app updates. Please advise me on what to do next.
You can't completely uninstall them but should be able to disable them. Go to settings≥Apps and show system apps too. Find them in the list and disable each one but be aware next ROM update they could be re-enabled again depending on Samsung's policy.
