last night was installed Android 7 Nougat on my Galaxy S7edge, lot of my favourite applications doesn't work with it, so I have download official ROM of Android 6 Marshmallow and downgrade it using Odin (AP file only). Now come the problem, my phone don't vibrate, I hear only very quiet beeping at this moment (time when it should vibrate).

I've already try both "wipes" in service mode, factory reset, other Marshmallow official ROM. No success. But it can't be hardware problem, because when I restart or power-on my phone, it shortly vibrate on startup.

Thx for Your help.

I have exactly the same issue with non-edge (standard) galaxy s7. I downgraded android 7 to 6 but used all four files from the official firmware (including home_csc file) which actually factory reset my device / erased data. I wasn't that bothered about restoring everything as I was relieved to escape from the awful Android 7 ui design. The vibration issue is annoying as everything else on the reverted Android 6 is perfect. I'm using official final xeu firmware for Android 6, for my device I believe this is G930fxxu1bpl2.

Just found this statement in another forum but not had time to look into it further... THE ANSWER TO OUR PROBLEM IS: We are running a Nougat Bootloader on Marshmallow

Not sure if this is correct as it appears that I have the latest android 6 bootloader G930FXXU1BPL2 (for my standard s7). However it does make sense that something from android 7 could be lingering as we both have the same issue after downgrading from Android 7 to 6.

Please post a solution if you fix yours!

I fixed it! Temporarily upgrade to Android 7 to fix the vibration issue then use odin to flash final version of android 6.0.1. You must flash all 4 files contained in the extracted (unzipped) firmware package but ignore the home_CSC file. IMPORTANT...tick the option in odin "phone bootloader update". This process will wipe all data on the phone full but will give you a fully functioning galaxy s7 with Android 6.0.1 marshmallow!
