Exactly a month ago Nokia had released a firmware for Lumia 800 that fixed few issues including the major battery problems. Now today, Nokia has released one more update for 800 that fixes volume bug. Even I have the same volume bug where my Volume goes very high in the start of the ring and also during playing games.
There are few more improvements included with this new Nokia Lumia 800 Firmware v1600.2487.8107.12070 like even more battery life, updated Camera application where it has now auto detection of 50/60Hz. The new firmware has been Code named as 12072 that will be available only in few regions, not worldwide until few more weeks.
As of now, there is nothing official on Nokia’s site hence we cannot say which countries will be getting this update but Vodafone Australia has revealed the same for few particular regions.
