- Proposed fix for viper for silent notification (Need to use viper from ROM Tool)

- Updated Xposed

- Gear users can now apply lag fix

- ROM Tool have following fix, read it carefully

Micro lag fix

Because of samsung security, some mods can cause micro lag. ROM Tool have option to fix it but, this fix may have some ill effects like,

- For XDA & Pro version users, Hybrid SIM Tray won't work with lag fix - No alternate available.

- For Pro version users following things may break

1.Navigation height customization.

Alternate - still one choice in ROM Tool will work but limited to one size

2.Long press back won't work

Alternative - Still all same functions like kill app or other can be assign with bixby/Long press home

3.360 Rotation

Alternative - Probably very few person may using it, will make it separate if require.

Lag fix have option to apply/remove and you can toggle anytime. Single click will fix it, long press will remove fix

Probably ROM still will be better compare to O3 without lag fix so you may skip lag fix if you are fine with performance.

BT Pairing Fix

ROM is prefixed BT reconnecting issue but Xposed may break it. If needed then you can use this fix.

Gear Fix

Usually won't require but keep as if needed. If you apply this fix,

- It won't break gear connectivity even after nandroid restore

- Disadvantages of this fix is 1.Can't use Lag fix 2.SPay won't work

Some special instructions about O4

- Installation is bit different and it may take 5-10 min to finish installation (average 7min)

- Magisk may throw an error about kernel patched with other SW, just ignore it, ROM is Pre-Patched so it's normal

This is pre-final version and may be in next version (Not soon) I may remove all fix including lag fix and may O5 come with everything pre-fixed, but before that I need some review.

Recommended steps to Install ROM

Most experience users have their own setup but for Newbies here I am describing my probable steps to clean install O4

1.If you are on other ROM then better install vendor provided in download area. Both version of vendor available 1.Odin flashable - extract and flash using odin OR 2.TWRP Img - Extract to get vendor.img - copy to SD card - select to flash img in TWRP - select vendor.img and flash

2.Factory Reset (without wiping Int storage is fine if you already did it previously) and Install ROM

3.Wait for Reboot device, once device boot check notification for any instruction regarding don't run any app/giving permission

4.Soon you will get option to apply 'Essential Fix' - Apply it and Reboot

5.Open ROM Tool when notification clear from statusbar and select desired option including battery/clock icon selection and again reboot once all set in ROM tool,

only skip micro lag fix

6.Now connect and install SW related to your accessory like Gear wearable/ VR etc For gear wear, you will auto notify with new gear detected option if you keep gear wear ready with reset.

7.If you are a Pro user, download latest version of Pro and Install it - Reboot after applying Pro features - Set up desired option in Tweaks

8.Now again Reboot device

9.Now lastly apply Micro lag fix from ROM Tool if you needs.
