Hardware....Alert slider or Action botton

If they give these things some critics will say "SaMsUnG cUpiED AppULe"

Apple also copy Samsung features.....no matter what other's say....Samsung should give this if they can

Why didnt you buy iPhone then if you knew you "needed" this? Hardware has patents on the design and functionality and its not very easy to directly copy it

If you guys remember dedicated Bixby button/key was introduced in earlier flagships of Samsung Galaxy S8 and Note 8 but due to criticism (as they limited the functionality upto Bixby voice assistant only) they dropped it but i guess they might would have customised it according to user's need like the alert slider or action button. They should bring it back with more innovative customisations.

Note- I also miss phones with dedicated Camera shutter button!

There is a feature named 'Side Key'
U can use it

Note:Side key is a present on power button..
To use it go to SETTINGS>SEARCH SIDE KEY AND IF YOU FOUND SIDE KEY OPTION THEN TURN IT ON AND YOU WILL FIND THREE OPTIONS
1) DIRECT ACCESS TO CAMERA
2)ACCESS TO SAMSUNG WALLET
3)ACESS TO OTHER APPICATIONS

U MAY USE AS A DIRECT ACCESS TO PHONE TOO
HOPE IT HELPS YOU..

THANKS AND REGARDS

Alert Slider - highly underrated, much needed, useful hardware feature!!
