Lumia 920 (windows 10)

I already told you in an other thread/topic why your 920 will not get windows 10 mobile.

It's just not supported  on a 920.

So that means there is no change for getting any windows 10 mobile (insider or public) builds on a unsupported phone like your 920

Please help, I updated and installed, there was a restart, but no change with my 920

Let worry ourself by entering in the wrong world of mobile OS, we have not forbidden to return to our lovely home "Android", WP is bias than you never expect hundreds devices are useless including Lumia 920

The 920 doesn't support windows 10, which is why you haven't "upgraded" it but installed an insider preview build. Use the windows device recovery tool on a computer to go back to Windows phone 8.1.

• If you want the Battery Saver to switch on whenever the battery gets down to 20%, select When battery is low.
• If you want to switch on the Battery Saver now and leave it on until the next time you recharge the battery, select Now until next charge.

When enabled, a small heart icon appears over the battery icon, and your phone does not automatically receive mail and calendar updates, update some live tiles, or allow apps to run in the background.
