Anyone else having a laggy experience on the latest build? Ever since i flashed the latest build my phone had a lower response time like you would tap on something and get a response 1 or 2 seconds later than usual. I thought it's because i dirty flashed the rom so i reinstalled with a full wipe but i got the same late response time out of the box on the initial setup menu.
Possibly samsung has made some changes to make the device slower but again if i am the only one having this issue then idk what's the cause. Reverted to an earlier build for now.

I, too, have a little slowness, for example when drawing a password. First I did a completely clean firmware. So the problem is something else. But I'm fine with it.

It supports LTE natively. Having said that, if something broke try to flash KoreanAddons. (I've read such reports for VoLTE)

Strange, no LTE with freedom mobile here in Canada for me. I'll probably test the Korean add-ons.


Btw the do not disturb button in the pull down shade isn't there for me.

Since I've heard multiple simliar bug reports new build is up now:
  • 27012022
    • Revert "Enforced SELinux policy"
    • Revert "The rom now passes SafetyNet naturally"
Hopefully this fixes it.

    [ROM][9][OneUI] Korea's rom for A5|7 2017

    As you probably know by now a Korean variant of A7 2017 has recently received firmware update to android 9 and OneUI. I made it working on my international variant and cleaned it up, so I'm sharing with the community.

    Code: 
    /*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

    However, if you still feel like you are missing features it is still recommended to flash an addons zip. So I linked the post above to the OP.

    FAQ
    Is it possible to flash stock oreo firmware after using this rom?
    Yes, of course. Flashing this rom doesn't update your bootloader.

    I have A5 2017, but battery capacity shows 3600mAh.
    You can ignore this. That's only in about phone. The kernel knows your true battery capacity.

    How to add csc codes
    Korean base doesn't support multi-csc. But we can still unlock region-related features by using special codes. I won't post them here, you should search around xda for the specific one that you need.

    For example here I will be adding network speed indicator in the status bar. The code for this is:
    Code: 
    <CscFeature_Setting_SupportRealTimeNetworkSpeed>TRUE</CscFeature_Setting_SupportRealTimeNetworkSpeed>
    But you can add something else, too.

    You'll need a PC. Steps to take are:
    1. Download THIS zip to your PC.
    2. Extract the zip.
    3. Open system/csc/others.xml with Notepad.

      It looks like this:
      Code: 
      <?xml version="1.0" encoding="UTF-8"?>
<SamsungMobileFeature>
  <FeatureSet>
    <CscFeature_Setting_ConfigOpMenuStructure>GLOBAL</CscFeature_Setting_ConfigOpMenuStructure>
  </FeatureSet>
</SamsungMobileFeature>
      Add your code like below:

      Code: 
      <?xml version="1.0" encoding="UTF-8"?>
<SamsungMobileFeature>
  <FeatureSet>
    <CscFeature_Setting_ConfigOpMenuStructure>GLOBAL</CscFeature_Setting_ConfigOpMenuStructure>
    [COLOR="Red"]<CscFeature_Setting_SupportRealTimeNetworkSpeed>TRUE</CscFeature_Setting_SupportRealTimeNetworkSpeed>[/COLOR]
  </FeatureSet>
</SamsungMobileFeature>
      Code:
    4. Repack the zip.
    5. Copy to your phone and flash.

    Now when you go to settings -> status bar you should see the network speed indicator toggle appear. Or any other change that you added.

    Updated the KoreanAddons zip.

    KoreanAddons.zip

    drive.google.com drive.google.com

    Flash at your own risk!

    This should be flashed after flashing the Rom (Preferably after clean rom install).

    What does this do?

    Adds your country's CSC and could add some features,mods of your choice. By adding the CSC of your country it may enable voLTE and other carrier specific features, voWiFi doesn't work as the Korean Pie Rom does not include voWiFi (WiFi Calling) related stuff.

    UPDATE: The previous zip had an issue with the battery cosmetic fix, fixed that. Please redownload.

    UPDATE 2: Fixed again, works with the latest rom version.

    New build up!

    • 04032021
      • Rebased on A720SKSU5CTL2
      • Updated the kernel drop from A720SKSU5CTL2
      • Slight a5y17lte-only firmware changes
    This build comes with a several week delay, but for a good reason. The kernel drop I was waiting for, as said in the post above, is finally here. Samsung did some smaller driver and security changes to it, so although it's minor it's nice to have the latest thing. Especially since this could be the last one.

    In case you haven't heard already, Samsung will no longer push security patches for it's 2017 A Series. You can read more about that in this news post. Unfortunately, this leaves this update as the last A720S firmware we can rebase on. But, of course, we see new roms (which take newer devices as a base) start appearing. And I hope that they can become more and more stable over time. Edit: I got pointed out that because A720S was released a bit later, in july 2017, we might or might not get one another security update.

    Lastly, need to thank my friend @Jmackley for covering me with testing and bandwidth issues. 😂
