Input lag on bluetooth gamepad in Android 11 - General Questions and Answers

Hello!
I'm experiencing an issue with input lag (it takes longer to register the pressed button and the response is late, or sometimes doesn't even respond) on a bluetooth gamepad in Android 11. I recently upgraded from Android 10, where I was facing the same issue. The problem was solved thanks to the app called Bluetooth Auto Connect + following a youtube tutorial, but now on Android 11, the solution doesn't work anymore.
Someone recommended to me to turn off all accessibility features, but they were already turned off since I started to use the phone. I also turned on the Gabeldorsche function, but to no avail.
Does anybody have any solution, which could help? Thank you for your time and help!

[Q] Bluetooth reconnecting every 10 minutes

Hi all,
Been reasonably happy with the z3 so far but I'm having problems with Bluetooth connectivity, specifically in my car. I'm used to an iphone, which works flawlessly, but the z3 only seems to be able retain a connection for 10 mins before slowly reconnecting. It's become frustrating as it restarts some of my tasker profiles(?).
Has anyone else had similar issues? Are there any known fixes for this?
I've tried turning off stamina, wifi, bluetooth timeout, display timeout, re-pairing my device - nothing has helped!
Cheers,
Russ

The normal Stamina mode (not ultra) won't disconnect any connection just limit background process.
This can be bug in firmware So try to repair it by PC companion
+ and a question; is this happen with another bluetooth devices or just with car?
cause if it happen with car it can be software compatibility & ...
Thanks for the reply. I thought I would update.
I did try checking for firmware updates but I found a different solution shortly after. I downloaded the 'Xperia Z1 Bluetooth Fix' from the google play store, installed it and selected the Tune2Air device (when it was in range). Since then I've had no reconnecting problems! I have no idea what the app has done but it has completely solved the issues I was having. I suggest giving it a go if you are having similar symptoms. :good:

I get this all the time, constant every couple of seconds when connected to my Mercedes Comand unit..
I will download this app and test it out, hopefully it sorts it.
I have Volvo V40 and when I step in my car with my bluetooth on, I see on my Z3 Bluetooth connect and then disconnect. This repeats all the time. When I then disable bluetooth and enable, the problem is gone. I don't know for sure, but what I have see on my car's phone menu, although I get these disconnects on my phone , the disconnects are not noticed by my car. But again, I didn't look into that yet. Do you have similar problems?
Hi all,
Great to know im not crazy bcuz im having the same issues in my toyota as the volvo. My phone automatically tries to pair & sometimes this works flawlessly, yet other times it connects, stalls, then spends an age tring to reconnect & all the while the cars head unit still perceives a connection. What i hav noticed is that i get great connections (fast & from where i left off) when i pause before switching off my car. If i dont pause then i need to manually connect even if the phone says its pairing with my car. Iv come from a nokia n8 which worked flawlessly however i could not control the volume from the phone which i can do from the z3 & i was wondering if the problem could be with either the phone or stereo having conflicting memory of what was last played, volume level , etc. As there must be data stored somewhere on either or both devices.
Look at this page for an explanation of Sony, seems to be a problem from the bluetooth version of the car:
https://talk.sonymobile.com/t5/Xper...s-connecting-disconnecting/td-p/853609/page/2
I dont think its necessarily the car as the problem i outlined is resolved if i pause the playing music before cutting power. I should correct an earlier comment. My problem is with playing music from my phones harddrive via a player such as the native music player, vlc music player, music visualiser, etc rather than streaming music so im not sure what peolpe using cloud services or internet radio can do.
Does anyone know why pausing the music before leaving the car is necessary when in my experience using bluetooth 3.0 didnt require this?

[Q] Bluetooth won't turn on

My phone was connected to bluetooth receiver in my car and while playing an audio book suddenly stopped. After that I've not been able to turn it back on, it attempts to and fails. I have not installed any apps recently and am still on 4.1.1 so I wouldn't think it is a software issue . The only fix i tried was to pull the batter and restart.
I'm hesitant to upgrade because other than this issue it's working fine. Does anyone know of ways to rule out hardware issues?
Thank you.

Bluetooth dropouts

heyho,
since im using KGL MTCD i have massive problems with BT in combination with apple.
First issue:
-BT autoconnect wont work every time, sometimes out of box (only enabling on smartphone) and sometimes i have to connect manually with apple to get i connected
#2:
-When im using speakerphone auto, mostly on every conversation, the soundquality has some massive dropouts, so i have to disable immediatly BT and switchin to my phone directly while im calling. first i tought it was an load problem with the device (maybe internal_sd or ram overloads) but the issue appears after clean and idling device,too.
i've contacted the reseller (erisin) to help me. so the sended me the newest stock-rom from oct 2016 and issue was GONE. Now im using malysk 11.1 and the issue is back again. i've tried some apks to fix it (like headunit.apk where i can switch the protocol from 2016 to 2015) but nothing realy helped.
anyone else has this problems?
i have really no idea how i can fix the call-issue. i need it 3-4x per day but in this case, it absolutely unusable
thanks

Bluetooth all paired devices frequently lost

Using Samsung Galaxy Tab A 10.1 with latest Nougat rom and this has been a problem since I have owned the tablet.
Previously had Asus Transformer Prime and never had the problem with same bluetooth devices.
Pair most frequently to a bluetooth speaker.
After several hours or a reboot, all paired devices on Samsung tablet are lost. They no longer show in the Bluetooth section under paired devices. If I turn on the bluetooth speaker, I am prompted on tablet with a pairing request and the options of OK or CANCEL. Tapping OK connects as expected and audio works.
However if I turn off the speaker or walk out of range, then come back several hours later or reboot the tablet, I must go through this whole process again because the tablet lost the paired device, when it should just auto-connect.
I haven't tried a factory reset yet because I was hoping someone would have a great idea to save me the trouble. Everything else on the tablet is working fine.
Found it was MINMINGUARD xposed module causing the problem. Disabled that module and it remembers bluetooth
Hopefully that helps someone

Android 11 - can't make call with bluetooth handsfree set after upgrade from Android 10

Hello,
After recent Android 10 to Android 11 update (latest patch from july 2022) on my Nokia 5.3 I have issue with my bluetooth car handsfree set.
It's working fine overall, but I have button which when was pressed twice automatically called last dialed number.
After update button is not dialing last number anymore - nothing happens when phone is locked or unlocked.
Button however works fine - I know this for sure, since it also stops multimedia play and end phone call when pressed once.
I tried to reset network and bluetooth settings, clear phone app and bluetooth cache, re-pair devices or even change bluetooth settings in developer menu.
It seems like some permissions issue, but all looks fine there.
Any idea what else may I try?
