Problem pairing with a smartwatch

Hi,
I recently purchased a Huawei Honor Band Zero smartwatch and pairing it with the P8000 is a pain in the ass. I may have tried around 100 times (no exaggeration) and I managed to get it just once. But then, once I got too far from the phone while wearing the watch and it disconnected, I haven't been able to pair the two again.
I've tried with my previous phone, a Xiaomi Redmi 1S, and they pair every time in seconds. Then I can send data from the watch to the phone, and setup the watch from the phone.
I asked @BlueFlame4, author of the visi0nary kernel, whether this could be solved at the kernel level (along with other bluetooth related issues, such as music skipping over BT) and he thinks that maybe the BT stack is messed up, but the solution could be hard to achieve.
Well, today I've been trying again and have discovered a difference between the Redmi 1S and the P8000. When I turn on BT on the Redmi 1S, the watch appears as both a known and paired device. If I tap the device's settings button I can see an input device profile I can activate or not on the phone, such as BT headsets showing audio and voice profiles or options to share phone contacts. Well, on the P8000, I see no box to set up the watch as an input profile. But I remember seeing it the only time the watch paired correctly with the phone.
How can this be possible? Any way (the phone is rooted, so I can do almost anything) to get it working like it does with the Redmi 1S?
Thanks.

Android auto - Redmi note 5 pro - no sound or very very less sound on car speakers

Android version: 8.1.0.opm1.171019.011
Miui: 10.2.20
Car: Ford ecosport
When I play music/use navigation in my car's head with the phone connected, no sound or very less sound is heard.
I am using Redmi note5 pro from about 8 months, the sound was working fine but not from last month.
Debug:
1. If I turn off Bluetooth (AA will automatically turn on BT after I turn off but sound starts to play in the car)
2. If I turn on "Do not disturb" mode also the sound is played.
3. Sound issue resurfaces after I skip a couple of songs, not while music is playing but when the song changes to the next one.
Also with Redmi note 5 pro there is a serious connectivity issue I believe.
My wife's phone( Redmi note 4) always connects without any connectivity or sound problem, but my phone always won't connect(I wil have to try a couple of times) and if connects doesn't play sound(I will have to do the trick of BT or DND).

Doesn"t safe volume level warning kick in after some time ? (it reduces maximum volume )

AirPods low volume with Xiaomi Redmi Note 8

Hi you guys, how's everybody?
Tried everything: updating the AirPods firmware with a new iPhone (connected both to chargers, AirPods connected to iPhone and all), nothing yet :?
With iPhone, the volume is great. With Xiaomi, the voice messages, music -volume is very very low, although all is on MAX volume.. Tried changing region, tried allowing AAC and disabling dual volume from dev setting.
Does anybody have a fix?
IMUI 11

Same problem with my redmi note 8 pro.
Tried all the things mentioned but didn t work for me
Miui 11 stable

Install Poweramp (don't enable MusicFX , unless you have ViPER4Android)
go to equalizer and adjust according to your preferance
if it still the same then your AirPods are fake ...

Try this; go to developer options and "Disable absolute volume" / Enable.

Thank you, tried this. Still the same
Ideas?

Same here! Someone has any suggestion to solve this? Thank you.

Hey, I have A redmi/xiaomi - on my side, I disabled the Bluetooth A2DP hardware (available on the "Developer options") and it worked really well

Low Volume Bluetooth Wireless Earbuds Problem

Hello there fellow Xiaomi users, I have a problem with my Bluetooth earbuds and it's driving me insane! I hope you can help me out. When I connected my newly purchased bluetooth sony earbuds (the model is WF-XB700) I noticed that the volume was really low, maybe 50% less than it should've been. I was perplexed, but had a couple of quick ways to determine the problem. I connected the earplugs to a Iphone 8 and they worked just fine, 100% of their capacity. Then I connected my Xiaomi Mi 2A lite to some other bluetooth headphones (model Pioneer se-ms7bt) and they also worked as they should've. Then I connected the earbuds to a Xiaomi Mi A3 and to my surprise, I could also detect the Low Volume Issue there too! So, it must be something Android/Xiaomi related.
Then I went on a really energy draining odyssey on google to find a solution. What I did find was, firsty, that it was a known issue and secondly, that the myriad of solutions presented did not help me at all. This is a list of the things I tried, some of which spawned problems too :
1) Disabling absolute volume in developer settings.
2) Tinkering with all the options in the develper option - even the following (I will copy paste in from an other thread , which according to many people has worked :
Enable Developer Options (options -> system -> about phone -> click build number 7 times)
Press back
Go to settings, and search AVRCP.
Click on Bluetooth AVRCP Version and ensure it is on 1.6.
Next, search for Absolute
Select Disable Absolute Volume and turn this toggle on, if it isn't already.
Unpair all Bluetooth devices. Restart your device. Pair the devices again. To the right of each Paired Bluetooth device in the Bluetooth settings page is a gear icon, go into each device and turn off the Phone Calls toggle, leaving only Media audio enabled.
Exit settings, connect to the Bluetooth device, start playing something. Increase the volume using the volume up button and rejoice as the volume goes as loud as you need!!!
3) Putting the volume up in the Sony Headphones app. - So, officially the app doesn't support the WF-XB700. There are two options for detection. The first is a list of the supported devices (mine is not there) and the other is a ,,detect via bluetooth''. Tried the second option but it doesn't work
4) Increasing the volume on the physical buttons on the device. Mine are earbuds and have only one button for on/off
5) Ensuring the eartips are tightly fit in my ear.
6) Making sure the earbud isn't blocked by anything.
7) Resetting the phone
8) Changing the Region - This I actually did not succeed in doing. It turns out that the option to change the region has been removed. If there is a way to do it, please inform me.
9) Trying all the volume booster apps in the store.
10) Restart or enable and disable airplane mode
11) Forgeting and pairing the device again
Could the bluetooth version difference be the problem. Mine is 4.2 and the buds are 5.0. According to google there should't be a difference regarding the sound volume/quality, only range and connection strenght. Please help me, I have wasted more than five hours already and I ran out of options to try. Thanks in advance !

Xiaomi removes Bluetooth codecs intentionally from this phone (and seems like from Mi A3 too). Because Xiaomi dont want to pay 1$ fee for codec. Thats why it works as expected on iPhone. It's all about greediness.
Same codec issue is proper on Miui roms too. This means Redmi 6 Pro has an Bluetooth codec issue too. We can probably say same thing (according to ur first post) for Mi A3 and for its Miui version Xiaomi Mi CC9e.
- Redmi 6 Pro
- Xiaomi Mi A2 Lite
- Xiaomi Mi A3
- Xiaomi Mi CC9e
All of them probably has same issue. I didnt use any flagship of Xiaomi or any other Android phone since Jelly Bean so cant say anything about other brands except Apple. I used an iPhone between those times. iPhones has proper bluetooth codecs. You cant fix it via resetting ur phone or something like that.
SBC is the default codec and none of others will work.
Qualcomm is the owner of these aptX, aptX LL, aptX HD, aptX Adaptive audio codecs. We have an qualcomm chipset on our phone too but xiaomi didnt want to pay for these to earn more money from us. So thats why we are stuck on SBC. Dont buy any android device just by looking its specs from websites. Check out everything in the shop (bluetooth, camera,..etc.) before buy.
