Samsung Galaxy Note 9
Was on P15 previously. Now jumped to Q17.
Noticed the significant battery drain. Anyone resolved the issue?
That will always be there. As Android 10 is a heavier OS as compared to Pie due to extra features and more advanced system. Extra features means extra battery consumption. So battery backup will always be lesser.

oh. Thank you very much Dr Ketan. i have flashed Q17 successfully. Currently my device is booting and installing the app. By the way, does Dr Ketan have a telegram group??
Có, như tiêu đề cho thấy.

Flash Bootloader và modem? Nếu vẫn xảy ra sự cố, hãy thử flash cùng một phần mềm cơ sở gốc và ROM.

Couldn't find the magnifying glass to search the thread and didn't do it manually but wondering why I get random reboots? Installed newer version recently and phone rebooted once yesterday and once today so far. Wondering if its a scheduled thing in a setting or something else is going on. Thanks!

Commonest causes of random reboot are
- Custom kernel
- magisk module
- xposed module

Check accordingly.

    SPay will never work one you root device. GPAY will work, SPay can work from galaxy watch though
    For safety net, it's recently started. Read latest changelog post of my S21Ultra thread,for how to fix safetynet
    I still have the issue 🤷‍♂️

    Google pay wont let me add a card. and no matter what, i fail the safety net
    It needs to pass SafetyNet
    For that you need riru magisk module + safetynet fix 2.1.1 or up
    Aliso needs to enable magisk hide +rename magisk app
    After that clear data of play service, play store, apply google pay fix from rom tool - reboot
    On Dr Ketan Q17 ROM is there a way to change ome and app screen grid size beyond 5x6 with using any 3rd party launcher? I want more icons on 1 page on default samsung viewer if possible.
    There are plenty of 3rd party launcher have it. You can use goodlock - HomeUp module on stock launcher too
    OK follow up question. I installed Good Lock from apk mirror but it gives error not supported in you region. What to do about it?
    Look in rom tool if it have goodlock option (not using N9 now a days so don't remember)
    Ok downloaded Good Lock from Rom Tool and installed it along with Home Up module but GL still won't populate and stuck on not available in your region screen.
    Thanks for helping :)
    You need to open HomeUp with rom tool

    Installation and Download

    Important :

    - This will void warranty.
    - As of now you will lose Samsung Pay and Secure folder forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA likely won't work once you root device.

    Installation :

    If you are on stock ROM/Recovery, follow below said steps

    1.Enable Developer Option (settings - about phone - Software information - Tap 7 times on build number to activate developer option in settings menu)
    2.Enable OEM Unlock from developer option (If you don't have this option then read this you can't flash ROM before this option available.)
    3.Download and copy ROM File to Ext SD card, Use ES file/Root explorer or any similar to check MD5, it should be match with provided in download section.
    4.Download TWRP
    5.Switch Off device
    6.Press Vol down + Bixby and then connect device to PC to reboot to download mode, press volume up when asked to continue to download mode
    7.Download Odin and open it, Disable 'Auto reboot' from option menu of Odin
    8.Select TWRP (tar image) with AP tab of Odin and Start
    9.Once Successfully flashed, you will see 'Passed' in Odin tab
    10.Disconnect device and hold Vol down + power till screen goes off, Now immediately press Vol Up + Bixby + Power to reboot to TWRP
    11.Select to allow modification
    12.From TWRP, Select WIPE menu - Then FORMAT DATA - You need to type 'yes' to perform wipe. WARNING : This will erase all data including Int SD storage from device
    13.Once format device completes, go back and select REBOOT' Menu and then - 'RECOVERY', This will reboot to TWRP again
    14.Now select Install and navigate path to Ext SD card - ROM zip file, you have copied earlier
    15.Read installation instruction of ChangeLog post for vendor.img It may be available inside ROM zip or may need to flash separately, depending on version of ROM
    15.Let device boot, and read ROM specific Instructions below.

    If you are on CWM recovery and custom ROM already, Follow below said steps.

    1.Download ROM zip and place on Int Storage/Ext SD and check MD5
    2.Reboot to recovery and select factory reset and flash ROM zip you have copied in step 1.
    3.Let device boot,Read ROM specific instructions below.

    Some ROM specific instructions

    1. On boot, you will see a notification about don't use any app that requires root, wait till that notification to disappear. This issue explained in MustRead.txt file in download area. Also after first boot, wait for ROM Tool to open, it will provide option for some important fix.

    2. ROM doesn't have any CSC included as now csc have separate partition (ODM). ROM will not erase/flash/modify files inside odm partition it and you will have your existing CSC even after flashing a ROM

    3.Vendor partition may be included in ROM or available separately (Read changelog of version you are installing) .It is recommended to flash it specifically you are on different base.

    4.Since Pie version, OEM is pre-fixed with kernel patch and after flashing ROM, you may find OEM option in developer settings but it will be disable, it is actually because of hack/fix applied. In real case if it is disabled then you may not able to boot rom with TWRP. Simply ignore it.

    Read ChangeLog of ROM you are going to flash for any specific instructions. Link to changelog is available in next post below.

    Can I dirty flash (without factory reset) ROM? No, We don't recommend it. If you are able to handle consequences with dirty flash then proceed, but don't post bugs in forum without clean installing ROM.
    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. ;)

    For Encryption - Read This

    Hello guys
    It's been first time I couldn't visit xda for about a week since last few years. I have planned update last week but couldn't. As we know life have some priorities, and xda is not on top so hope you can understand. Trying my best to come back but yet unable to give date. May this disappointing for some but hopefully you will try to understand.
    Thanks in advance for understanding and keeping patience.
    Again sorry for delay.
    Dear friends,
    When whole world is fighting against corona, being a doctor, my service is more important to my society and my country as doctor, till our fight end, I am taking leave from android development.
    Wishing you and all a healthy life.
    Take care,
