I'm in Greece. Phone is rebooting intermittently, 1-2x almost everyday. No issues with sd card. Did one factory reset for another issue (word&excel not working) but reboot still happens after it. Still got issues with OK Google getting access to mic, seems another app is occupying it.
Just got a Samsung s7 edge. OK Google not working - "can't use microphone. Restart unit" . Does not help. Funny thing is I say "OK Google " and a window opens saying can't use microphone. How did it hear it in 1st place? Checked permissions and they are OK.
Further developments :took phone back to shop and they recommended leave it there for5-10 days or make factory reset. I did factory reset and now excel and word works. I think smtg happened when I did the data transfer from s6 to s7.
Tried restarting phone, no help. Today downloaded the MS office mobile app and in there clicked word and then excel. For both apps says my phone is not compatible. Ridiculous.
