Samsung j5 sleep mode

Unless it actually says it's has a sleep mode then it will be in Settings somewhere. Tap the Apps icon and select Settings - the one wth the gear icon.

Tap My Device then Display and Screen timeout. Set it to the highest number of minutes. It will affect battery power and charging more often.

My problem still here.

My bank sends me a ' one time password ' after I log on. The password is not being received. I get calls, texts etc. Without any problem. Any ideas?
