Call your telco to push carrier update.

even i turn off raise to wake function? Normally b4 ip7 is machnical button, that mean the ip7 home capative button is always listen to new command when the phone is on stanbdy(off screen mode) ?

bcoz i do not want this feature turn on to save batt,

Just now my 7plus hang, both power n home button also no response
Need to keep repeatly press only can works then I reboot, while shutdown n starting up also can notice the hissing sound
So sad

Normal hissing is ok, but like mine can hear it over 10cm under benchmarks, i don't know is that normal or not, or anyone willing to test on their phone, under antutu benchmarks? My antutu score around 140000-150000, unlike the ranking list in antutu which iphone 7 plus can score 172644.
