Lumia 1520 RM940 Win10M 10.0.14388.0 - Lost Back Arrow Backlight

I have a Nokia Lumia 1520 RM940, the AT&T 32GB version.
Currently on Redstone - Win10M 10.0.14388.0

I Lost Back Arrow Backlight a couple of preview builds ago.. maybe 14371? The back arrow is also a bit intermittent.
Has anyone else seen this?

While I was immune to most issues users complained about... starting with the June fast track builds my battery life has plummeted. Whatsapp and Camera app are especially acceptable to causing the phone to reboot with the Low Battery Message... even if I had say 30% showing just seconds before.

Yes.. I've done the full hard reset ...restore nothing... install every app from scratch route.

I have a 1520 running the latest insider builds and I don't have any issues you mention. In fact the battery life has somewhat improved from the stable builds.

that back light being out seems to coincide quite a bit with the mic not working. replacing the usb/mic board fixes them both.
