[OnePlus 8T Guides, News, & Discussion] Shavi_Suri:
Hey everyone!!

Greetings from my side. We were trying hard to get 100% working oneplus dialer and messaging app in oneplus 8t. and Yes, We have successfully done it.

I am very happy to share the guide with you all :)

WITHOUT ANY ROOT METHOD: (Thanks to some anonymous help for non-rooted ;) ;) :p)

- oos11 required

-Please download this OnePlus Dialer: Link

-Install it and open it, set as default.

-Give all required permissions only.

-Enjoy guys, this dialer app has no bugs at all.

-If you want to use OnePlus contacts and message app please download them from old method below, these two has 1 minor bug which is not noticeable in daily life, So enjoy them at fullest without rooting your device.

Root methods below:

Requirements:

- oos11

-Root

-Magisk

- OnePlus Apps v1.0 Module

-Your own responsibility before following the all steps

To root your device with magisk please follow this amazing guide by @DroidFreak32 :

NEW METHOD(Recommended): Big thanks to @shadowstep for your contribution and providing us this amazing module.

1. Download OnePlus Apps v1.0 Module from the above link.

2. Open Magisk App and select it to flash.

3. You will get Option which app you want to install from all three apps(Contacts, Dialer, and Messaging).

Because few users do not want to install all of them together and only want to install a particular app.

4. You can select them using volume keys: Volume Up for Yes, Volume Down for No. (Refer Screenshot for better understanding).

5. Reboot and voila, Apps has been installed successfully.

6. Please make them default apps and give all required permissions.

7. Clear Catch for dialer/messages/contact app before using them.

8. You are ready to go. Thank you.

Points to be noted:

-These apps are not permanently stored in the system storage because we cannot write in the android 11 system, So do not remove/disable magisk. Wait for TWRP to come up.

- No need to disable Module while doing OTA.

-You will not face any issues while using these apps. Reboot will not remove these apps unless you remove/disable the magisk module manually.

- If OnePlus dialer comes with your 8T and call recording is locked in your country, please download this app and enable it without even rooting your device. (This point is not for google dialer users).

- Same as other OnePlus phones, you can see the recording files in the dialer settings itself (Find out screenshots below) OR

OLD METHOD:

Please download the required dialer apk from this link:

https://drive.google.com/drive/folders/1814cAPa4y1yP2lJfvIQwkZTmoajxuEXi?usp=sharing

If you need messaging and contact app as well. I have shared it in the above link.

- Download the Busybox Module in magisk

Open the hamburger menu again like before, then head to "Downloads." In the search bar, do a search for the term "busybox" to locate the next module for this guide. Tap the download arrow once, then go to "Install" to start the install process. Once finished, tap the back arrow to return to the previous screen.

-Download the App Systemizer Module

In the search bar for the "Downloads" section, do another search for the term "app systemizer," then repeat the process like before to get the module installed. Once this one finishes installing, you can go ahead and hit the "Reboot" button at the bottom to restart your device.

-Install the Terminal App

To use the App Systemizer module you downloaded in Step 3, you'll first need to access a terminal. The module is entirely command-line based, which is why you also needed the Busybox module — it allows you to use more advanced commands with superuser permissions.

Play Store Link: Termux

-Store the dialer in some of your specific location which is provided in the above google drive link.

-Systemize the OnePlus Phone App

Open the Termux app, then type in the command below, followed by: (Please do not use " in all steps below commands)

1. "su"

When you're prompted to do so, tap the "Grant" option to give Termux full superuser privileges to your system.

2. Now that your superuser permissions have been granted, type in the next command followed by enter.

"systemize"

This command will immediately launch the App Systemizer module interface for the first time. This is easily the best way you can turn any user-installed app into a system app with minimal effort.

3. Choose option 3 only which is via .apk (Choice 1 & 2 not working in our 8T). Choice 3 was the best way to make the dialer work in 8T.

4. Now give the apk location. For me, I have placed the apk directly into storage. Enter the following line.

"/storage/emulated/0/Phone_Dialer.apk"

5. Now type 2 to install to /system/priv-app and then reboot the device.

6. Please make oneplus dialer as default phone dialer. It is very important step.

7. Now app has installed successfully. Please disable google dialer for now.

8. Please give all permissions to oneplus dialer from phone settings(calls logs,contacts,files and media,microphone, phone,SMS)

If you are facing any issue in using systemizer app, please prefer this link . This link also contains screenshots for first few steps.

If you have followed all the steps carefully, You will have a working oneplus dialer with call recording. You can enable call recording from dialer settings.

I am attaching the screenshots for your reference and I will keep updating the guide for better understanding, so please do not create multiple guides with the same steps.

It is 100% tested and working fine. If you will face any bug, Please let everyone know in the comments below.
