Hotspot not working, and weird bluetooth problem - Xiaomi Mi 9 Questions & Answers

As much as I would like to use a custom ROM on the Mi9 to fix my problems it seems like gpay either doesn't work or is extremely difficult to get working so I'm stuck with stock for now.
Since day one with the device i've been unable to get wireless hotspot working, it connects but no internet works it sometimes very intermittently will open a webpage but then says no internet again and ping will stop working this is the same for all laptops I try with it. USB tethering works fine but that isnt' an option for my work laptop. Has anyone experienced this problem? I've tried all the settings, 2.4ghz / 5ghz etc.
The next problem is bluetooth, in my car I have the car bluetooth which is just for calls and then a audio bluetooth device for music, it connects to both fine.
After I have a call in the car I lose all the audio streamed to the audio bluetooth device despite it still being connected. I have to unplug this device to reset it and then it starts playing again. This is definitely a problem with the mi9 and not the device as I've tested other phones.
I'd be grateful for any advice on this.
Thanks

[FIX] Possilbe A2DP Streaming Workaround

Stuttering and skipping streaming are very known issues on many jelly bean devices.
The most times when I listen to music in my car, i do this via bluetooth. So it is really annoying me and some day, I will have an accident, while I am fumbling with my HTC One.
I replaced the audio.a2dp.default.so with one of the Nexus 4 (4.2.2) and it just worked well, but only the first time using bluetooth streaming after rebooting the device.
I changed some settings in audio.conf and it still stutters.
But then, i deactived wifi while the device was streaming and all stuttering and skipping was gone.
So... can someone just confirm, whether the a2dp streaming works correctly, when wifi is deactived?
I want to know, whether this is the only point to get this work and I don't want to change my working mess
is nobody interested in this?
I posted this bluetooth issue a while back on this forum, and the issue is corrected by switching off WIFI while using BT. Apparently the new update which is due soon fixes the issue but only one user has confirmed that so far.
Since I use bluetooth streaming on the car mainly, I use Tasker so that when Bluetooth connects, it automatically switches WIFI off (don't need WIFI while driving and saves battery), and when it disconnects it switches it back on. This way the phone just works seamlessly.
Just turning the wifi off and back on again when I connect bluetooth seems to solve this issue for me.
i can confirm - turning wifi on/off fixes it as well for me (until next time I go bluetooth)
I discovered this a couple of weeks ago too. I was about to send it back too. Cant live without podcasts and audible in the car!
I have the problem that i cant even here any sound on my HTC CAR A100 Car Stereo Clip, even if wlan is deactivated With my old sensation everything is okey..

I wonder if this also improves the bitpool value. I'm noticing on my HTC One that bluetooth streaming quality is not very good. From what I've read it has to do with a bitpool value that it set too low, increasing this value is supposed to increase the streaming quality. Highs sound distorted on my phone over BT I can't believe Google/HTC have not addressed this issue.
I have not been able to solve the bluetooth audio streaming issue by turning off WiFi for my car. It works perfectly fine with my Jambox even with WiFi turned on, but in the car, it does not work either way and I'm using software version 1.29.401.13

I'm running 1.29.401.13 too and it looks like it is working nearly perfect for now. I can remember only one time, when it stopped for a second. Mabye the car radio is facing similar problems? Did you try to update the firmware or whatever of you car radio?

I've tried researching how to update the firmware of my car's bluetooth, but have had zero luck there as well. It's a 2009 Acura TSX.

Did you manage to fix the problem with the A100 as mine is exactly the same, works fine on my Sensation but no the HTC One.
have the same problem:
If wifi is ON and bluetooth is ON, eg at streaming youtube over the bluetooth headset, it stutters and has distortions.
If wifi is OFF and stream a video from the sdcard over bluetooth all is fine.
what i find out:
I use the JellyBean from Quarkx for defy.
The build from 7.3.2013 worked
All later builds, with the new wifi driver had this problem.
But its a known bug that JellyBean has a2dp issues, i guess.
This trick, to change audio.a2dp doesnt helped me
I didn't noticed any problem with my phone even when the wifi ON, I'm using the latest radio "4A.16.3250.24_10.38.1150.03L" found in this post: http://forum.xda-developers.com/showthread.php?t=2245615
I don't know if it can help..

[Q]/[HELP] Xperia Z-SBH20 connection issue

Hello!
I bought an SBH20, paired with my XZ via NFC, listened to music, then disconnected the headset, using the NFC.
After a while, i tred to connect again via NFC but all i get is a 'connecting' message, BT turning on -white BT icon- but no real connection, therefore the BT turns off.
After several tries it finally connects, but it's not reliable this way.
I noticed, if i enter to settings(not turning anytihng on/off) and trying to connect (still using NFC), everything works fine: connects, disconnects perfectly, and handles the BT as it should.
I've reseted the headset, tried single and multi point modes aswell. Deleted the BT devices, then repaired, still got the problem.
Am i doing sth wrong? I want to connect and disconnect the headset with a simple touch, and not toggling the BT manually (NFC yeah...) Is this something, SBH20 is not compatible with?
(btw sony support says: "For subsequent connections between devices that have already been paired once, make sure that Bluetooth™ is turned on so that the devices can connect automatically." If it's a "must" , then what is the [email protected] use of the NFC??? Just to pair once???)
Please share your experiences! Any advice would be greatly appreciated!
Thanks for reading ( and sorry for my english)
I actually have the same problem using the SBH50. For me sometimes it connects perfectly fine, other times it doesn't and I have to go into bluetooth settings after which it seems to connect properly.
I have noticed that it also depends on how I disconnect it; if I remember to touch the headset to disconnect then next time when I try to connect I have more chance of it being successful. Also, when I try to connect I hold the headset aganist the phone even after the ‘connecting’ popup until I get the 'connected' popup.
These are just work-arounds which aren’t always 100% successful though so would be good to find out what the proper method is.

It is a real shame... In my case it's the opposite, if i touch the headset to disconnect, the next nfc-connect tends to be less successful.
(and i noticed that it also matters if i turn off the headset after disconnected, or not)
And what is really odd, that i don't have to do anything in the settings menu ( or bluetooth settings) just open it, and everything works like a charm...( all connect or disconnect tries are succesfull, no exception, even if i push the headset repeatedly to the pohone's back)
I'm not affraid to mod some system files, apps, maybe build.prop tweaks, but i don't know where to start. In bulild.prop there are only a few nfc related lines (tried to enable/disble those)
So i'm not alone...maybe even more people are in the same boat, trying to solve this.
Again; any related info is welcome
I also have a sbh50 but i normally disconnect by turning off the headset. I have set it in smartconnect to turn off bluetooth automatically when the connection shuts off but it doesnt always do that.
It reconnects with no issues when bluetooth is on and i turn the headset on again. I use the nfc tap only for the initial pairing.
The only issues I have is the google music skipping issue that i posted the other day and the gmail smart connect not working on the sbh50

Well, then we don't have the same issue. I tought i could use the nfc for connect/disconnect (i actually still think it is capable of that, just sony messed up sth)
Could you try to connect/disconnect and connect again with your devices, please :angel:
I'm really curious about this whole nfc story ( why does the headset have the chip/tag if it only works for initial pairing -its not a big deal to pair manually, especially that it has to be done just once-, and on the other hand: if i put nfc in the device, why not put in this functoin too- not a big deal: a proper working BT toggle, but it brings a tad more functionality-

Problem with wifi and bluetooth when they are both turned on

Hi
I'm experiencing an odd problem with my phone. I'm on Skydragon rom (android 4.4.4) and I'm experiencing the following problem (quoted from another site with the same issue):
I have wifi on all the time and working properly, no network drops. I connect my bluetooth headset. Wifi still seems to function properly. Only when the bluetooth is actually in use (ie. listening to music or taking a phone call on the headset) does it seem to disrupt my wifi connection. If I turn my bluetooth headset off, wifi will work perfectly again without any drops.
Does anyone have any insight into this problem? I have tried changing radios, hboot, the works and nothing works.
Cheers

Anyone having problems with Bluetooth

I previously owned a Sony Z3v and had no complaints. I run and workout regularly so I often use bluetooth headphones while doing so. These in particular http://www.plantronics.com/us/product/backbeat-fit. I'm been having issues since day 1 with these disconnecting. I have to power them down and power them up again to reconnect. Even when they lose connection, they show they are connected but are non responsive. I had not trouble whatsoever with my sony experia.
Anyone else having these kind of issues? I've checked the forums and I don't see any reports. Is this isolated?
I only use Bluetooth when I'm in the shower with the beats pill but it works great for me.

Not entirely related but I have had issues with my original Galaxy Gear disconnecting somewhat frequently when I disconnect my BT head unit or at other seemingly random times that sometimes require me to turn BT off and on again. It's not that huge of an issue usually but BT on my S6 is not perfect for sure.

I am having Bluetooth disconnect issues with my car. Will connect and disconnect repeatedly for about 7 minutes and then stay connected. Very annoying. Have tried several fixes but nothing has worked.
I haven't had an issue with mine when using it for my gopro.
The issue is with Android using Bluetooth 4.0 and WiFi simultaneously. I've had these issues since owning the phone. For whatever reason if you connect your phone to a bluetooth speaker where both devices are BT 4.0, the WiFi will be extremely slow or not work at all.
If you don't believe me, try it. As soon as you connect the device, try to load something like a video or song over WiFi. Or even send a Facebook message. It'll stall. As soon as it stalls, turn off WiFi and it'll magically start working again over cellular data.
No issues here, usually stream to a Bose Color Sound device, getting connection through WiFi
I have issues with mine pretty regularly with my car. A reboot of the phone will sometimes fix it. It's annoying, sometimes it will disconnect from audio but not phone or vice versa. Or it will work perfect, I'll get a phone call and it all goes to crap. The remainder of the drive will generally result in fighting with it. Maybe it will reconnect, but most of the time it won't. Never have I had a phone with so many bluetooth issues.
Had issues with my truck head unit / phone BT. Phone would continually disconnect.
Tracked it down to the Messages transferring to head unit.
If I disabled Messages in the Bluetooth / Allow Access To area, it worked fine, but obviously messages wouldn't go to my truck.
I cleaned all messaging apps, factory reset truck head unit, no fix. eventually factory reset the phone, havn't had any problems since.

WiFi and Bluetooth Not Working Simultaneously

I recently purchased a bluetooth headset (Audionic B-666), but I am unable to use it to its fullest.
Whenever I connect headset while my wifi is on, internet connection stops working. Chrome shows not connected to internet.
If I connect headset first and then connect wifi, headset disconnects.
Headset works fine with my falcon and laptop.
I am running fully stock 5.1.1. Updated to build 10.7.A.0.222.
I know it is a known bug. Is there any permanent solution to it? I have read on different forums that factory reset will fix it temporarily. Is there any way to fix it without returning the device?
Or my only chance is to flash a custom ROM?
Anyone?
