This post is admittedly aimed at a small niche sector of our customers. If Developer Options, ADB and Marshmallow don’t mean much to you, it is safe to disregard this post.
If you’re still here, then we will assume you want or need to enable Android’s Developer Options on your Marshmallow (5.x) based device…
Please note some of these options can have an adverse effect on normal day-to-day usage. If you’re uncertain what to change, please contact us or the person who originally recommended you enable Developer Options.
If you return back one more screen (to the darker Settings area seen when the two cogs are clicked on the homescreen), you will find a corresponding new entry, just to the right of where you previously clicked More Setting.
