Samsung icons keep disappearing from screen. they use very well but the image icon gets black. first samsung members icon disappear then after update it comes back but Samsung video icon disappear. now after the new update it fix but phone icon is go...

my alarm keeps getting miss. i set 5 alarms on my phone to wake me up but none of them ring. due to this i didn't get wake up early. it's really problem if flagship like s8 doesn't ring alarm on proper time.

s8 front and back camera doesn't work perfectly.it doesnot focus clearly and faces in pictures are slightly bended towards one side its big problem for device.it happens with me after 3 beta update.

is there any engineering mode code for galaxy s8?

my proximity sensor doesn't turn screen off during calls. but in *#0#* it works well.pls help me to solve this problem:(
