[Android Head-Units] dape16:
With OEM head unit the reception is fine. With the PX6 head unit the FM reception is quite poor. I have checked that the OEM amplifier gets power. I have tried one of those small "FM amplifiers" but it just made it worse.

So I am thinking about getting an external antenna like this one:

Eightwood DAB/DAB+ Antenna Car Radio Antenna Splitter: Amazon.de: Elektronik

Eightwood DAB/DAB+ Antenna Car Radio Antenna Splitter: Amazon.de: Elektronik

www.amazon.de

They seem to get good reviews at Amazon but I am curious to hear if anyone here been using it with a Chinese Android head unit and if it made any difference?

Thanks! 🙂
[Android Head-Units] TheBigRoberto:
I use one on a Joying HU, It works great. FM is perfect, GPS is also spot on. DAB worked on my last HU but, I needed a new DAB box for this HU, so I didn't bother. The bit rate for DAB in the UK is shocking, streaming is the way forward for good sound quality.
[Android Head-Units] ab1702:
I’ve had one before and dab and fm radio worked perfect.

You should be able to get the oem aerial working properly though with this unit.

Have you got an adaptor for the antenna to go into the new unit or does the oem antenna cable just plug straight into the new unit?

The fm amplifier that you bought will make it worse because the chances are that your car will already have a factory fm amplifier.
[Android Head-Units] dape16:
Yes, I have an adaptor for the antenna, from Fakra to DIN. I have tried to disconnect power to the OEM amplifier, and then I got almost no reception at all, so I guess the amplifier works.

But I have realized that DAB+ sound quality isn't very good, so now I am hasitating to buy an external antenna. And just stream music and radio from apps.
[Android Head-Units] ab1702:
If you get a good external antenna the sound will be better on dab. I use dab all the time.

It’s one of these that you need to get your FM working properly with your factory antenna https://www.ebay.co.uk/itm/353322093865 you connect the blue cable to the blue cable that comes out of the back of the headunit and it powers your factory antenna(although you should have got one of these with the headunit).
[Android Head-Units] IG_Vasilich:
I bought similar antenna https://www.amazon.de/gp/product/B073R8KW7F to try to get better reception of DAB+ (instead of windscreen-sticked antenna), and for DAB it made so much better reception, so i have now DAB+ reception even in my underground parking place %) Cannot say though about FM - i had no problems with OEM antenna before, and new antenna didn't make FM reception better. But as i don't use FM anymore (DAB+ converage in my area is good, and with new antenna i don't have reception problems in other areas either, all FM stations i was interested before, are available over DAB), i compared audio quality DAB+ <-> online radios. Yes, the quality of online services is mostly better, but:

1. while driving, with all exterior sounds (tire noise, air whizzing @ high speeds, noise form other cars), i barely hear the difference.

2. hearing online radio with e.g 128kbps, will eat ~60 MB per hour. If it is OK for you - ignore it.

3. The 3G/4G coverage (at least here, in Germany), isn't perfect - i had already 3-10 minutes of "no internet" while driving, but, surprisingly, DAB was available there.

4. with proper DAB+ software you will get additional services, like possibility of radio recording, or timeshifting (personally me use it often while hearing some news and got distracted with road traffic).

So, after using similar antenna (same manufacturer, but with aerial rod) during last year, i have never had problems with DAB receiving (neither with FM, but i had no problems with FM reception with OEM antenna either).

LineageOS is a free, community-built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

What I've notice:

- Volume buttons from headsets not working

Another issue it has, it's something that happens in all LOS ROMs published in this same forum for merlin and its that when you are listening any Whatsapp Voice Note through earphones, bluetooth or loudspeaker and screen turns off or you change main app and move Whatsapp to background, audio starts cracking.

Hi, sorry for the late answer.

Yes, the volume issue I was pointing only happens with wired headsets.

I don't know why I still have the issue with WhatsApp Voice Notes while screen is off. I checked sensors aren't covered by removing the case, but it still remains.

UPDATE: Sorry for not doing my homework, I forgot to disable ViperFX4Android Magisk Audio Module and try with module disable. Problem disappeared while audio module is disable by Magisk Manager. I understand there are things more relevant than fix issues with audio mods, so sorry if I wast any time.

Hi all,

I just got my new Xiaomi Redmi Note 9 and I already miss LineageOS.

I was happy to find this thread but before trying this build I have two questions.

Is this compatible with any version? I have the Italy, Germany, France, Spain edition. Do you think it could work?

Also, in case something goes wrong, how do I reset the factory image?

Thank you so much.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] MyBrainIsAStrainer:
I bought mine in Germany (so it's probably the same version), and it worked fine with every ROM I've tried so far - within their respective limitations. Currently running Kraken, though.

Keep in mind that you will need to downgrade to MIUI 12.0.1 (Indonesia) or 12.0.3 (Global) before you flash, otherwise it won't work. Ask me how I know.

As long as the bootloader is still working, you can flash the stock firmware back onto the device via fastboot (which obviously has to be installed on your PC). There's a website with all versions. Get the fastboot type, extract it, and run the included script (flash_all.sh on Linux, probably flash_all.bat on Windows). There may also be a GUI way to do it, but I can't help you with that.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] TheAegidius:
Hi MyBrainIsAStrainer,

Thank you so much for your reply. I'm starting to grasp something.

I guess downgrading to 12.0.3 global would be similar to restore in case something goes wrong. But I can't find that version in the link you provided.

Also, how did you find this LineageOS image and why did you choose to run Kraken? Were you having any troubles? I never heard of Kraken. What's the difference between Kraken and LineageOS?
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] MyBrainIsAStrainer:
Basically, yeah.

The main site only lists the most recent versions, but there's a link to the "MIUI archive" where you can find the older stuff.

Oh boy. I've been trying so many ROMs that it's hard to keep track of it in my head.

Kraken has no missing/not working features listed in its description. Also, Communos kindly provided a Kraken build that had the GApps already included, so you don't have to mess with MagiskGApps. And Kraken just was the more recent (and thus hopefully up-to-date) build.

I tried this LOS 18 back when I had the phone new. I had some issues with it which, in retrospect, were not the fault of the ROM but due my inexperience with newer Androids. Like, when I was boy, we just included SuperSU as an additional ZIP in TWRP's flashing process to get root access and called it a day. Nowadays you have to use Magisk, which requires extracting the boot.img from the ROM first, patching it in the Magisk app on the phone, getting it back onto your PC, and then flashing that patched image in the bootloader. The more complex a process is, the easier it is to make mistakes. Which of course I did. Because - well, look at my username. Also it seems that if you use Here Maps (a navigation app) with Android 11, you can't move the map data to the SD card anymore. Stuff like that.

For a while, I had SparXFusion's LOS 17 running, because frankly, it can do everything I need, and I was familiar with it from my other phone. But it wasn't getting updates, so I had to upgrade to an Android 11 ROM. That lead me to PixelUIPlus, which I chose because it was tagged as official. I thought that would give me more consistent updates. The original build worked fine, but when I updated to the most recent version, it actually broke everything (no boot, even after flashing other ROMs). I had to do the firmware reset I mentioned earlier, get MIUI to boot once, then I could reinstall TWRP and flash a new (and different) ROM. That was Kraken. It works, but I had it only for a couple of days, so I can't really claim much experience with it.

At the end of the day, they're all based on AOSP, so the differences aren't really that huge. Try a few, see what you like. It's easy to switch. And they're all better than the atrocity that is MIUI. As I wrote in another thread: People had warned me about MIUI, and I had thought: "C'mon, it can't be that bad!". But it could. And it was.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] Communos:
Nice, also for magisk you can just flash the zip like one used to do for SuperSU.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] TheAegidius:
Hi @MyBrainIsAStrainer and @Communos,

Thank you for all this information. It's very helpful to me.

The most annoying thing for me is that you need a Windows machine to use the Xiaomi tools for unlocking the bootloader and flashing a new image. With my old Pixel XL I used to do everything with adb and fastboot from Linux.

@Communos, so basically, with this LineageOS build, you can't have a non-rooted phone? I can't do that because my bank's app doesn't work on rooted devices.
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] Communos:
You can have a non rooted phone, it's upto user if he/she wishes to root or no,
[Redmi Note 9 ROMs, Kernels, Recoveries, & Other De] MyBrainIsAStrainer:
Tried it, didn't work for me, because at that time, there was a new version of Magisk for which no flashable image had been created yet. So I'd flash the old version, launch the app which told me to update, then the new app version would tell me that I'd need to also update my boot image, which it failed to do live from the app itself. And then I ended up having to patch the image offline as described aboved.

So now I do it that way right from the start to save time.

Oh, trust me, that's not going to be the most annoying thing. The hoops that Xiaomi makes you jump through make setting up a Windows VM pale in comparison. I don't remember the exact process (because it was so very complicated), but I recall having to link several accounts together, making certain settings, and then waiting for a full week. They made me wait not because it was necessary, but because they could.

I mean, kudos to Xiaomi for even allowing to unlock the bootloader. It's more than some other manufacturers do. But it could be so. much. easier.

JFTR: In case you don't have a Windows license for your VM, you can download a trial version of Windows 10 Enterprise from Microsoft (just google it). Perfectly legal. You don't have to activate it (in fact, it can't be activated because it's a trial), but it'll run for 90 days. Should be long enough to unlock a phone, even if it's a Xiaomi.

If you don't install Magisk, the device won't be rooted. However, part of the reason that Magisk is so complicated in its installation with the patched boot image (as I understand it) is because it employs some clever techniques to hide from the root-detection-algorithms of apps such as these. You can enable these hiding features in the Magisk app.

So your banking app might not even notice the rooting. It's always a bit of a cat-and-mouse game. The app developers come up with new tricks to detect root, and then Magisk needs to update to hide from those tricks again. But you can give it a try.

But personally (and this is just me, YMMV), I wouldn't use any smartphone for banking at all. I do my banking with Jameica under Linux and a 20€ tan generator as a second factor. Much more secure.
