Galaxy S4 update?

[Steven Rice]

I have a Galaxy S4 phone that is still running Android Market. I have tried to update it through the Settings, but it won't update. How do I update it to Marshmallow or higher?

The quickest way to update it would be to find the appropriate firmware on sammobile.com or some other hosting site and flash it using Odin. You'll need the exact model number as Samsung has this unfortunate habit of releasing boatloads of models with the same name, but vary just enough so that firmware isn't able to jump from one to the other. The problem I see, though is that a quick search shows the S4 stopped being updated after Lollipop, so if you want to go to Marshmallow you'll have to use a custom ROM rather than an official one. Not to mention that the S4 is old and probably not going to give a great experience with Samsung bloat.

If you're willing to give an alternate Android version a try, you can take the S4 all the way to Android 10 with LineageOS.
