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.
