"I have the same issue with my note8 after 3 months usage.
First seller claimed it misuse and now sent to Samsung itself for repairs as phone has never fall down nor has phone suffer the least damage. Every precaution has been taken since usage and phone is as newly bought.
Now seller sent phone to Samsung technician and awaiting feedback.
I faced the same issue too. This problem just happened a couple days ago where I realized that all of the sensors are not working at all. I search for the solution and none of them solve the problem. Is it because of the software update? Because i never drop my phone before at all since i bought it 3 months ago.
It should be a hardware problem,if not the sensor test shuold work on this cod *#0*#,if its not working you can cheack it through Samsung member official application given by Samsung to diagnose the faults, cheack and let us know.....
Gave the note 8 to Samsung service center to Airlink warranty claim , they fixed my device in 1 day , and got the device back right now in my hand . Device seems to be not opened, means I think it was software crack somewhere. Because my device have itnstalled 360 glass protector and it didn't removed or seems to be re applied, it means device didn't opened in Samsung services center, they fixed it through software I believe. Thank God mine is get fixed without any major issue . If you guys have Samsung warranty then you should go to service center ... If any one didn't have Samsung warranty and facing this type of problem.... better install factory stock firmware in it .. thank you and Good Luck"
