Anyone could please confirm that below codes really works and if yes then it's safe for the mobile.
1. *#9900# Turn On the Low battery dump. To resolve the charging issue.
2. *#0288# To enhance the battery performance.
3. *#9900# open Debug level enable and select "High" to make mobile work faster. After using this code, mobile utilises the processor max and mobile works faster than before.
The above codes are working on A7 2018. Don't know if these codes are working in all other Samsung mobiles.
Ya I used all the three codes. Before using these codes, one must restart his mobile. After that only use the code and restart again. My main concern was slow charging. It's working. Charging better than before. Yes, I changed the debug level to "high" in my A7 2018. I am feeling phone is slightly smoother than before. Regarding 2nd code, I need to observe as last night only I used the code. Many other codes are there but I used these three codes only. After Android 10 UI 2, my battery was taking more time to charge & also draining faster than before. I don't know if others having A7 2018 faced the same issue.
How many of you don't want to lock / unlock the screen by fingerprints, face, pin, password? Just want to swipe option to unlock the screen?

Dear Samsung Customer Support team. I have already sent the 2-3 feedbacks through Samsung Members app. The geedback & queries were regarding the Android updates and using swipe option to unlock the screen but by keeping the registered fingerprints. Right now its asks to delete the registered fingerprints to use swipe option to unlock the screen. Whereas in A5 2016 which I am also using have option to keep the registered fingerprints while using swipe unlock option. So I keep my screen lock on swipe and use registered fingerprints in A5 2016 to lock/unlock the apps through the fingerprints. But in A7 2018 its mandatory to delete the fingerprints if I opt to unlock screen by swipe option. I have received copy paste reply from your end for which I also replied you that you copy paste the same reply for all queries & feedbacks.
