I have failed to connect both phones ( Galaxy A7 2015 - aa) and (Note 9 - SMS and calls) . I disabled via root all bluetooth services on the A7 but as soon as AA launches ,Note 9 disconnects from the car. Mac spoofing does not work either.

Any solutions yet ?
[Android Auto General] KrisPerry:
Sorry to dig-up an old post, though did you find a solution?

Mine is similar in that the BT phone disconnects as soon as the android auto handset is plugged in. This happens regardless of bluetooth being frozen on AA device or MAC addresses being matched.
[Android Auto General] pflarini:
I fisically remove bluetooth apps with a system app removal.
[Android Auto General] juanmontequinto:
Any app to cancel the bluetooth that works?
[Android Auto General] red_fork:
App quarantine works for me.
[Android Auto General] KrisPerry:
Yes i have done this already. All bluetooth apps removed. AA still drops the original bluetooth device as soon as it connects
[Android Auto General] juanmontequinto:
With this application you can cancel the bluetooth > https://play.google.com/store/apps/details?id=com.kunkunsoft.rootservicedisabler&hl=es

Look at the video: https://www.youtube.com/watch?v=h77mkaUca0U&t=8s
[Android Auto General] KrisPerry:
Yes I've already tried this, bluetooth is completely disabled on my rooted s7 that I use for AA. bluetooth still disconnects from my s9 when the s7 is plugged in for AA, and cannot be reconnected until the s7 is unplugged.

How does AA identify and differentiate two different devices? I have tried cloning bluetooth/device name, bluetooth MAC address and model number, though AA can still tell the difference
[Android Auto General] juanmontequinto:
You have to cancel the "shared services via bluetooth". It works for me in an S5
[Android Auto General] KrisPerry:
Tried it, doesn't work. I think its my car causing the issue. I reckon even on a device without bluetooth, the problem will still occur.
[Android Auto General] jojo61366136:
I've been playing around with a 2-phone setup in my '17 Subaru Impreza.

I've actually gotten both phones to work simultaneously without issues. Android Auto and regular phone/media streaming actually work with 2 phones!

I have an old Galaxy S6 with only WIFI that is hotspotted to my current Galaxy S9+.

The S6 is permanently connected to my HU's AA via USB.

My HU recognizes the S9+ as the primary phone connected for "Media". When I hit the Apps-->AA, the screen switches over to the S6 and displays full AA with sound from the S6.

If I hit the "Media" button on the HU, the system switches over to the S9+.

So far, I'm liking this setup since I enjoy viewing Google maps on my larger 8" HU screen vs my phone. For calls and some other streaming services (like TV), I switch back to my S9+.

Somehow, things just work and there's no bluetooth conflicts.

I suspect each car manufacturer and specific radio unit will act differently.
[Android Auto General] marius23mvp:
I have a related question here.

I have a successful 2 phones setup on my car.

- My media phone is an A3 rooted, with bluetooth turned off - this phone is permanently connected via usb. Also this phone does NOT have a sim, so no data plan - I give it internet on wifi from a hotspot made from my main phone ! I use this phone for navigation (waze + google maps) + youtube (carstream + aa mirror).

- My main phone is an S8 non-rooted, that automaticaly connects to my car via bluetooth whenever I start the car. I keep this phone in my pocket, and I automated the enabling/disabling the hotspot using a little app called Carspot Ready (when it senses the bluetooth connection to the car it automaticaly enables the hotspot, and it also disable it when I get out from the car).

So - it's a successful setup in a way that both my phones are connected to the car at the same time - the media phone via usb - it gives me navigation and stuff and the main phone via bluetooth - it gives me handsfree calling trough car's speakers and microphone, as it shoud be.

Ok, now my problem and question. When I have connected ONLY my main phone via bluetooth (let's say my media phone is off), without doing anything to my main phone, (not even getting it out from my pocket) I can : initiate/receive calls and messages and use google assistant for voice commands (when I press the voice button on my steering wheel - the bluetooth connection routes the command to google assistant on my phone from my pocket).

So yes, to my surprise I have conversational level of comunication to my phone's google assistant ( I can ask it not only basic stuff like to call someone, but also some more advanced commands like what's the weather like, what's the exchange rate, who was the first president, etc etc ...).

But when I enable also the media phone - the one connected via USB, all this communication with google asistant is routed to this usb connected phone. I repeat - I don't have a sim inside this phone. If someone's calling me on my main phone (the one from my pocket), that phone being connected via bluetooth - I have a notification on my car's display that X is calling, and I can answer using my button from the steering wheen, all ok until now. I can also initiate calls, BUT NOT ANYMORE BY VOICE COMMANDS.

I can call someone from my car's touch display.

If i use voice commands for anything - it will get routed to the usb connected phone. Ok, that phone also has google assistant that can answer to my questions, but if i give the command to call someone it does't know to adress it to my bluetooth connected phone, it's trying to call from my usb phone, that does not have a sim card.

My toughts on this are to try ti disable something more on my rooted usb connected phone, just like I did with bluetooth.

But If I disable google assistant than android auto will not start on my media phone.

Any toughts what shoud I disable so that I will have google assistant answering me from my bluetooth connected phone ?

Thanks, and sorry for the long post
[Android Auto General] jojo61366136:
This is EXACTLY how I want my setup to be! I need to install that Carspot Ready, that sounds fantastic for automating the hotspot option.

And yes, I also have the same problem with asking google to call someone, it gets routed to AA and my secondary phone with no SIM.

My only solution to this is to dial straight from my actual primary phone's screen and not use voice commands.
[Android Auto General] lazycatbj:
that is what you need do : Phone A - connect to car for call ; Phone B - connect to Android Auto

1. clone the phone A Bluetooth mac address to phone B .

2. enable phone B Bluetooth and reconnect it to car with android auto.

3. disconnect phone B from car and disable phone B Bluetooth services and Bluetooth sharing services.

4. pair phone A Bluetooth connection to your car again.

now you can use phone A for call and phone B for android auto only .
[Android Auto General] marius23mvp:
Good ideea with this bluetooth mac cloning ... will give it a try and post what happened. Thanks. Any suggestion about what app should I use to clone the mac ?
[Android Auto General] marius23mvp:
Unfortunately no joy with bt mac cloning ... I've cloned the mac from the calling phone and give it to my android auto phone. Than I connected to the car with aa phone, than I've disabled the bluetooth.

After that when I tried to connect my calling phone to car's bluetooth I've got an error ... but I deleted the pairing and paired again, and I got exactly where I was before - my calling phone connected by bluetooth and my aa phone connected by usb.

I can initiate a call only by pressing on my car's touch screen, just like before.

I was trying to initiate a call by voice command (after pressing the voice button on my steering wheel) but, just like before, this operation will go throug my usb connected phone, and I got a "not registered on network" error, because I don't have a sim card on that phone.

I still think that the answer is messing with the services on my aa usb connected phone(rooted). Just like I've disabled the bluetooth, I should disable something else, so that when I give a voice command I should get an answer from my bluetooth connected phone
[Android Auto General] Note10.1Dude:
This appears to be very head unit dependent. I'm pretty sure in our Subaru if I hit the PHONE button on the dash, I get the BT connected phone even when another phone is plugged in and has maps/directions running through android auto and BT turned off. I haven't tried calling/texting within the Android Auto app.
[Android Auto General] indestin:
I tried to disabling(ROOT) BT,but not working.

How to clone the BTmac?
[Android Auto General] gmick:
All you need to do is disable the Bluetooth package with pm disable --user 0 com.android... (sorry I forget the package name, list packages with ADB to find it) Bluetooth will never work until you undo this command.
[Android Auto General] indestin:

[Android Auto General] Medicina200401:
Hi. Has anyone managed to get both bluetooth to work?

What method did they use to change the bluetooth mac? I did it by editing the file that is inside the efs / bluetooth folder, but when I go to check the mac address in (settings / status) the mac address has not changed.

If I disable all bluetooth services, I can connect another cell phone, but the bluetooth in the permanently connected cell phone doesn't work for me and I need it to connect the obd2,

Thank you

Alexander
[Android Auto General] moare01:
Hello,

I have the same problem.

What kind of Headunit do you use? And what kind of car?

You couldn't do it without the reset? I just deleted the pairing.

Both devices now have the same BT Mac and the same name.

Without success. :(

Do you have an exact Manual?
[Android Auto General] danchitu86:
And can you please provide some apps names to spoof the MAC? I can find just for wifi... Thanks!
[Android Auto General] moare01:
For Samsung devices, the MAC in this file must be changed.

[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
Hey guys,

I still had over 4h SOT all the time so I didn't think about testing the battery capacity from my Mi mix 2 but now I did.

The phone was automaticly shut off at 0% battery life and charged to 100% + 30min while it was shut down.

Look at this garbage, you should check your device to cause the Battery is rated at a max of 3400mAh and 3300 min.

PS: My device is not even three month old.
[Xiaomi Mi Mix 2 Questions & Answers] Deleted member 7447728:
Maybe you just got a duff battery, send it back for RMA/warranty. Mine's working fine.
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
Are you sure this test you have done is 100% accurate?
[Xiaomi Mi Mix 2 Questions & Answers] Wahoux:
I have my Mi Mix 2 since end of September, and battery life is still as good as first days
[Xiaomi Mi Mix 2 Questions & Answers] 1500cc:
I don't know how you were testing, but I suspect it's not quite the same as how the OEMs rate their batteries. For example the discharge rate, ending voltage, and depth of discharge will all affect the reported capacity.

Unless I'm really using the phone a lot, I easily get two days' usage between charges. So it doesn't matter to me if the battery's "true" capacity is 3400 mAh, 2700 mAh, or 20 mAh ... bottom line is I'm very happy with its performance.
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
I am pretty sure it's not quite the same. He would probably have around the same result when testing any other smartphone.
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
No it's not 100% accurate, cause there must be a few % reserved so the battery won't die completely from deep discharge.

But the result how much goes into the battery is correct. I also attached the device to my oscilloscope.

And no I don't get such bad results on other phones. (Tested with an iphone, nexus 4, LG Flex 2 etc.) Also some cheap chinese power banks have better ratings.

If someone else could test it that would be nice, cause I haven't found any spare batterys so far...
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
Try a regular 5V 2A charger in stead of the QC3.0 charger that's in the box, i'm pretty sure your result will be different.

Seems like you are coming to a conclusion pretty quickly, you are bringing it like everyone should expect a 2700mAh battery in stead of a 3400mAh. One guy's battery test does not exactly represent all units out there, even if your test is fairly accurate.
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
No the results won't be different. I can measure from 0.1 to 50V and as I said I did a second test in which I had my oscilloscope connected the results were the same.

And you're in the wrong again, everyone should expect at least a 3300 mAh battery minus the capacity which is reserved for deep charging like how it is stated on the battery.
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
Yes i'm wrong, you are right. Thanks for all the scientfic evidence and extensive testing. I think everyone should BEWARE now, they will all get a battery with only 2700mAh capacity.
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
Yeah you're. Check the ****ing battery ratings instead of flaming me and talking nonsense. Where did I say Everyone has a battery with only 2700mAh capacity?...
[Xiaomi Mi Mix 2 Questions & Answers] Mackay53:
Calm down
[Xiaomi Mi Mix 2 Questions & Answers] GuestD2308:
Hmm

There is a possibility we haven't talked about - the BMS only charges the battery to 2.7Ah and leaves the rest untouched. Why? Because as the battery ages, the BMS may adjust to charge to greater capacities to compensate. This is a technique I have seen and implemented in my own projects with LiPo and LiNMC cells with small drains.

If the pictures and OS are accurate, the battery is rated for 3.4Ah.

If the measurements are correct, which seems plausible, we may only be using 2.7Ah.

Tell us more about your battery shutting off too early. Custom ROM? Bluetooth?

I've only owned the phone for a few days and it's been fantastic - I get MUCH better battery life than I expected. The system reports 3.4Ah, but I will plug my phone into a coulomb counter when I get a chance.
[Xiaomi Mi Mix 2 Questions & Answers] animaleyes76:
Same as that. A steady 6.5 to 7 hours SOT everyday.
[Xiaomi Mi Mix 2 Questions & Answers] Twotems:
Same here. If it's only 2700 (which I doubt) then it's a damn efficient phone.
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
Ok look what a User named MPC561 found

https://de.aliexpress.com/item/3400...2de2-4c16-8d0e-ac23fbd88f3a&priceBeautifyAB=5

So ali is selling Mi Mix 2 batterys. Obviously they are not "original" but most likely they are just rebrands coming out from the same factory.

Ali is rating the battery from 2801mAh to 3500mAH.

I suggest other users to also test their batterys so we can figure this out. If Xiaomi has lied with teir battery ratings it was the last phone I bought from them. Cause if the rating from Ali is true it's ****ing battery lottery.
[Xiaomi Mi Mix 2 Questions & Answers] Mackay53:
There's nothing to figure out. If this thread didn't exist you wouldn't even bother looking into it.

If battery was so important then everyone would be buying power bricks
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
Yeah sure, just because you have a good battery doesn't mean everyone can be happy.
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
Yeah sure, just because you have a bad battery means Xiaomi lied about it.

Here is my results from 10% to 100% via QC3.0

I dissapointed
[Xiaomi Mi Mix 2 Questions & Answers] Julz2k:
Seems like you got around the same capacity. Could you please charge your phone from a complete 0% (auto shut down) to 100% and let it connected to the charger for at least 10 more minutes cause even at 100% it pumps a few more mAh into it :)

Thanks!
[Xiaomi Mi Mix 2 Questions & Answers] 60cent2007:
Here is what i got after charging from 0 to 100% (1A charger without QC)

Seems like I have to RMA my phone.
[Xiaomi Mi Mix 2 Questions & Answers] Treshy:
You guys do understand the difference between 3.7V Cell Voltage and 5V Charging Voltage right? Your batteries are fine.

2750 mAh @ 5V are about 3700 mAh @ 3,7 V. Factoring in loss in conversion and charging inefficiency its safe to assume your batteries are perfectly fine. No need to RMA.
[Xiaomi Mi Mix 2 Questions & Answers] DavidRJ:
This guy gets it, I'll just break down the numbers further here. After all the confusion in this thread, you guys need to understand how capacity is calculated - I wonder why you even have a USB multimeter if you don't.

Taking the nominal voltage of the Mi Mix 2 which is 3,85V and the USB voltage which is 5V, you get a factor of 1,3. Now let's take the average result you guys got from your meters, around 2750mAh (quickcharge readings don't count here, they work with up to 20V which further manipulates the outcome). So 2750mAh would mean: 2750*1,3=3575 which results in a 3,85V capacity of 3575mAh

Now the Mi Mix 2 has a typ. capacity of 3400mAh and a min. capacity of 3300mAh (every battery is different and not perfect). Let's take the average of those which is 3350mAh. 3350/3575 would translate to a charging efficiency of 0,93 which is splendid. As your batteries tend to age over time and the typical efficiency is around 0,9, you guys would have about 3200mAh in your batteries which is absolutely normal.

Also, the higher the charging current, the lower the efficiency. Those kind of tests are best done with currents of max. 1A, and never with QC3.0.

Btw, same is true for every power bank. Take any test on the internet of a high quality power bank from Anker for example, with 20.000mAh, you will always see about 12-13Ah on those tests. This link explains everything about it.
[Xiaomi Mi Mix 2 Questions & Answers] CrazyBeaver2377:
Thank you for clearing this up. All these people instantly going into rage mode thinking their battery is faulty or Xiaomi is lying about the capacity.

Hi everyone ! I appreciate this forum very much since we do help each other here. So thanks in advance !

I've recently got a Samsung GS7 which was a carrier operator based system (Orange France) and recently, it gave me a bootloader error. I did reflash the bootloader with a newer version and also the system (Android 7.0 FTM) via Odin, all was working perfectly till I downloaded Antutu and tried the benchmarking, when the system went to the CPU multithread, the phone did reboot and when it started, I uninstalled that application to avoid problems. Then, the phone didn't want to reboot afterwhile.

I'm blocked with a black screen and all keys combination doesn't work.

I really need help. It's a G930F. If you need any information; just ask.

[Android Q&A, Help & Troubleshooting] ChupaXL:
Yes, I did flash all 4 files (BL, CSC, AP and something else as described in odin).

I did try the Smart Switch recuperation feature but it didn't gave me any option, then after flashing with Odin, I did retry once the phone has completed his turn on ignition, it just gave me a feature to upgrade the phone.
[Android Q&A, Help & Troubleshooting] Teddy Lo:
The Emergency Software Recovery and Initialization you need manualy to do like in that video , first you need to put your phone in download mode .

Because you say that screen is black hold just power button for about 10 second to make sure your device is off , then Hold vol - Home and Power to enter in Download mode for bout 7 second and then release power button , wait just litle and then press vol + like for odin flash and then try The Emergency Software Recovery and Initialization. If it Doesn't work try with old version of firmware to flash , if you are able after that to enter in to recovery Wipe Cache Partition and Reboot your phone.
[Android Q&A, Help & Troubleshooting] ChupaXL:
The Emergency Software Recovery has been removed from Smart Switch. Sorry to say that but I can't access it.

Also, I can't enter the download mode or the recovery mode. I'll wait until the battery goes empty, and then, will try to charge it to see if it changes anything.
[Android Q&A, Help & Troubleshooting] Teddy Lo:
You can try that , but try this , press and hold just power button and plug USB on PC and your phone to see if is your device recognized as Exynos 7422 for example if it is then your Bootloader is dead .
[Android Q&A, Help & Troubleshooting] ChupaXL:
I did try that but it don't give me anything. The device is not recognized.
[Android Q&A, Help & Troubleshooting] Teddy Lo:
Strange , maybe your battery is dead or you have phone with hardware issue : / . Try to put him in charger for about 3 hours .
[Android Q&A, Help & Troubleshooting] ChupaXL:
I think it may be a software issue, the battery was working fine three days ago, I was working with the phone for about 5 - 6 hours without charging, it wasn't a battery problem.

Tomorrow, if letting my phone discharge and then charge doesn't work, I'll put it in charge for 3 hours.
