T547U – A Perfect Device for Android Auto Head Unit​

Afaneh, thanks for your great work. SM-T547U is a very special device, manufactured in 2019, and ignored since then. What I mostly like about TWRP is its excellent and clean Backup & Restore of the entire Android Operating System, everything done outside of Android environment. I have tested this TWRP brought forward by Afaneh on my “Galaxy Tab Active Pro” and it works without flaws.

I have bought this special device to install it in my car as a head unit. Checkout the web and see for yourselves what guys are doing with their tablets to bypass the expensive head units manufactured by the OEM like Kenwood, Alpine, but these OEM head units lack full compatibility with Android devices. The current Android Auto is still in development stage, it takes so long to connect with Android devices and whenever it does so, only about five apps in your android device are synced; not worth it. Whenever these manufacturers create new things, they downgrade their innovations at the same time to save money. The new 10 inches screen sold by these manufacturers no longer come with DVD function, the offline GPS removed and Google map added so that you pay to navigate the streets, their WIFI-certified does not necessarily mean that you can use it to navigate the internet and update softwares, but just to connect your external devices,…the list is long. Below is a link to an example of what I want to do with my tablet…

According to the above video which was recorded in 2017, Root + Xposed are needed to carry out the project, and since Xposed was not yet available by then he recommended choosing SM-T825, most especially for those living in USA and for compatibility with AT&T.

Well, as for me, I am choosing T547U because its technical features are far better than that of T825. Also remember that T547U is a North American model and it is compatible with all registered telecommunication companies in the USA and Canada. When I bought T547U, it came with Canadian Android version, and after unlocking the bootloader, I installed the USA Android version. See the attached image called "CSC_Code", showing all the available companies in the USA that you can switch to, for their extra services if you want. Xposed is available for Android 10_Q and 11_R; I have it installed on my T547U (see the attached images below). For Root and Xposed contact Afaneh, the Admin. What I like about his project is the electrical connection and the software programming of the tablet to get information from the automobile. If you know of better programming softwares than the one he has used in the video, let me know. To install my T547U, I will use the Ram-mount specially made for my device as can be seen in the following link. It has POGO pins, which means I will be inserting my device to use in the car and removing it to use at home (theft-proof).

The reasons why I have chosen T547U is as follows:

1. This is the only tablet that I can find in the market with 7600 mAh battery and it is removable like the old phones! I hope we all know the advantages of a removable battery.

2. It has a USB-C v3.1 with DEX function, compatible with HDMI. The HDMI which means Audio + Video + Data through the same port makes it easy for connection in the car and eliminating the use of so many adapters.

3. As a Samsung device, it has a very wide support groups that know how the firmware works.

4. It has 3.5mm jack. Many modern devices no longer have this.

5. It has LTE and a SIM-card slot. Its use for cars is explained in the link to the video.

6. Its ruggedness is fit for use in extreme conditions. P68 dust/water resistant (up to 1.5m for 30 mins). This means if you like you can permanently install it in your car and park it outside under -30 degree centigrade. This ruggedness is my warranty that is already built into the device. So I’m not worried about losing the Samsung warranty for unlocking the bootloader and rooting T547U. All my old devices that I no longer use are still working; this means if I take good care of this rugged tablet, it will outlive the Samsung 2-year warranty with so many conditions that hardly gives you a new device in exchange when something goes wrong.

7. I don't care about Wi-Fi calling that discourages so many people from unlocking and rooting their devices because it is not always a free service. Additional charges may apply – in case your Wi-Fi connection is lost for some reason, the call may switch to your data and cause you to pay extra. The best Wi-Fi calling are Skype, WhatsApp, etc.

Thanks for your attention. See all the attached images, and I will keep you informed as I progress.
