Iam not a good thread maker so i will try to write everything as simple as i can.
Few days ago i bought and switched to A7 2018 from A5 2017, which was/is still an excellent phone to me.
On A5 i was on Oreo and on A7 i am and will be still on Oreo. Not planning to test this on Pie, but be my guest and try it on Pie, some stuff should work. Report if it does.
On A5 i made a similar thread to enable some features, but it was much easier to do because i had a CSC folder instead of ODM folder which has some files encrypted and you need them decrypted to proceed. And there is no flashable zip, you will need to do all on your phone, except decrepitng some files which you will need to do on your pc, and then put back and overwrite the same files on your phone and give necessary permissions.
First of all iam not a developer and i dont know anything about developing.
This is just enabling some features that were allready there in the phone through some lines on some files in ODM/OMC folder and some lines implemented in the stock floating_feature.xml file.
Never delete floating_features.xml file from your phones etc folder and dont touch permissions (0644), or your phone wont boot up. You just need to edit them and save.
Iv tested only on stock A750FNXXU1ASA4 OREO, which was only rooted and nothing else was modified.

The features you should get if everything goes right are:
1. Floating messages (option in Advanced features)
2. Record calls in (phone options)
3. Show network speed (option in status bar)
4. Data Usage Notification (option in data usage)
5. Camera Shutter sound on/of (in camera options)
6. ScreenRecord (options accessible from QPannel and Advanced Features)
7. S Bike Mod
8. Places option on keypad
9. Caller ID spam protection (in phone option)
9. LiveMessages in samsung keyboard
10. S PowerPlanning (Device Maintenance/battery)
11. HomeMode(screensaver option)
12. S Pen features( needed if you ever find working AirCommand).
13. In Samsung video options, but in option that apear when you press play on video,
you should see Video Enhancer option. Download Samsung video from Galaxy apps.
14. Multiuser support
15. Dolby Atmos dual speaker (works with speaker not just with earphones)

Anyway...
I f you dont know anything about floating_features.xml or bulid.prop or ODM/OMC folders and editing them, then dont try this beacuse I won't be held accountable if something happens to your phone if you loose your data or go into bootloop! So Dont Forget to Backup your Phone!

INSTRUCTIONS:
1.You have to be ROOTED offcourse and have a file manager like RootExplorer or simillar.

2. Now you need to copy from root of your phone two files from your contry ODM/OMC folder that your phone/SIMcard uses. It must be from your contrys ODM/OMC folder no other ones. The files are cscfeature.xml and cscfeature_network.xml After you decrypt them put them back in your phone and overwrite the ones inside your contry ODM/OMC folder and give permission 0644.
After that open in text editor with your Root Explorer cscfeature.xml file and on the bottom insert the lines that you can see in the attachment, then save and restart the phone.
To decrypt cscfeature.xml files follow this thread:
https://forum.xda-developers.com/android/software/decode-encode-omc-files-omc-decoder-t3791471

3. Now open your floating_feature.xml which is located in system/etc folder and just edit/enter on the bottom of the file lines that you can see in the attachment, save and restart the phone. Dont do nothing else with this file just insert the lines then save and restart the phone. If you delete it you will go in to bootloop.

4. Now open your build.prop and on the bottom of the file enter lines that you can see in the attachment, save and restart the phone.

5. Now copy all files in system from the attachment and put them in their corresponding places.
Give perrmission for folder 0755 and 0644 for files.

Thats it!

I hope it works for you like it did for me.
Il try to answer any questions, when i have free time.
And if you all have problems doing this i will make a video tutorial when i have free time.

Does this tutorial applies to a7 2018 with android pie? I mean do I have to decrypt those files? I just want to enable call recording.

So can I enable only call recording without decrypting those files? I've did it on my s8, just copied the csc code into build.prop...it will work on this device too?
