Hi
I have this problem with Samsung Ace 4 new model... no idea how it occured but now everytime I make outbound call, the big padlock logo appeared with message: Double Tap to unlock ...
This keeps on happening. I tried to google for answers and there are a lot of suggestions BUT none works.
- this is not Screen Lock settings issue
- this is not TalkBack settings issue
BTW, this problem can occur in many Samsung smartphones (as from the info gathered online)
I have emailed to Samsung to seek help but no reply from them yet.
My last option is to do a factory reset but before doing so, I like to know if anyone faced such problems? Please share how to remove this padlock setting forever...
