[AC Question]

When I update the youtube app on my s6 ( just the youtube app ) I get an -501 error message upon Installing the update . Downloading the youtube apk through chrome or something installs the app with no probs . I read so many articles about clearing cache . I cleared the cache and data from my browser , chrome , google play , google play services you name it .

I have the same problem. When in chrome, it will not launch the YouTube app from chrome videos tab. Restored the phone twice and it worked for a bit, but the next day it did the same thing. Now the YouTube app will not update, I just receive a 501 error.

Even I have the same problem on my S6 with the youtube app. I've tried everything but i still get the error 501. If anyone got the fix to that error plz update me with the fix

Have you already tried to reset app preferences? You can do this in settings - apps - overflow menu (three dots top right) - reset.

Try this;

Settings-->application manager-->downloaded--> find app name that you are trying to install, for example if you are trying to install evernote, and getting 501 error, you will see it like this ''com.evernote'' at that section. Probably it is residue from previous installations that cause error. Click on and uninstall it, after that play store will let you to install that app witohout any error.
