Keyboard help

Hi guys.
I reset my pixel C today, and started fresh, but my keyboard isnt pairing with the tablet...... When attached, the prompt appears to turn on BT, but the numbers requried to pair never appear, plus, when manually pairing, it just seems to time out, no numbers appear either.
Have reset tablet again, have also reset network settings, and have also tried to pair the keyboard with another device - same behaviour, time out.
Is there a hard reset available for the keyboard?

If you can pair to any other BT device then flat battery in keyboard? I've no idea how you can tell!

i use to own the folio but have sent it back. i'm not aware of a hardware reset on keyboard. however, i also had this problem and became frustrated so i just turned bluetooth off but kept the keyboard attached for about a day. the tablet had been rebooted a couple times. when i had become calm enough to turn it on i was greeted with a paired keyboard. it may have had something to do with a battery in keyboard not charing because it was not attached for a few days.

Ok, so, I had another pixel c keyboard at work (my original one, dropped it on the plane, lost 2 keys, so I ordered my current one about 2 months back). and even though that has been off for 2 months, it paired up, first time.....
So the tablet must be working fine....just seems the "current" keyboard doesnt want to re-pair.
Almost tempted to swap the missing keys onto the old one.....just afraid I'd screw that up

That would be my first guess.

I lost my keyboard after the 7.0 upgrade. I am not sure, but I don't think I ever had keyboard after that. I have done hard reboots and "forgot" the keyboard along with every other BT device. Then I pair, key in the six digit number <ENTER> and it sits there saying Connecting... forever.
I bought mine in early June(Pixel and keyboard). It is not rooted and stock. Who is the to call about this?

I contacted tech support. They had me go to safe mode and pair and connect to keyboard. No change.
But then he asked if I could give him the serial number of the keyboard. I removed it from the tablet to search. Of course, there is no SN on the keyboard but I did find it on the box. While re-attaching the keyboard, it CONNECTED for the first time in days!!!! I rebooted in normal mode and it still worked. I unpaired and re-paired and it connected immediately.
I had the tech cancel the RMA for now.

I'm having this issue after returning to 7.1.2 from the Android O beta. Contacted support they were baffled. Keyboard out of warranty so no go on an RMA. Doesn't connect to my pixel or pixel c says incorrect passkey but never gives an option to enter one.

Try this, I finally got mine working after probably more than a year of not working at all... https://forum.xda-developers.com/pixel-c/help/finally-fix-bluetooth-keyboard-pairing-t3647393

Can´t mirror Zenfone 2 Z00A in my car dd2026 hansei device

Hello everyone,
I love my Zenfone 2 Z00A, me and my girlfriend, both have one. I need help with both of them. We bought a car that comes with a multimedia sound system, witch in cludes a display that is both compatible with IOS and Android. My problem is that neither my Zenfone 2 Z00A running Lineage OS (last weekly build 27/01/18), nor my girlfriend´s Zenfone 2 Z00A running stock 6.0 android, can´t mirror our screen in the device. The audio system is a DD2026 Hansei model.
I´ll run the steps so that anyone can plz tell me what else can I try.
1 - Enable USB debugging in phone settings.
2 - Activate the mirroring function in the car display.
3 - Connect the USB cable
4 - My phone asks to permit the USB debugging, and I say yes.
5 - On the screen a message telling that the connection is starting gets a green arrow indicating that the conection happend.
6 - In the cellphone the app easyconnection opens automatically.
7 - The car display freezes in a screen that says "Please autorize the instalation of cellphone internet service in the cellphone". This message keeps blinking and nothing else happens.
What makes me mad is that I tried with my sister in law MOTO G4 and after the step 5 the screen in the car just changes to mirror her MOTO G4 screen. In her phone, the message indicated above do not blink while the connection is happening.
What can be happening that permits the conection between the car and the phone, but then don´t complete the connection? Anybody has a clue? I´ve been trying every change possible in settings and can´t make it work.
Please Help

I can't configure the Fingerprint Sensor on my LG G7 ThinQ

Hi all!
I cannot configure the fingerprint sensor, when I press any finger, it only vibrates, but it tells me that it may be dirty, which is not the case ... any idea what it may be?
I tell you that I tried with the official Android 9 ROM of my model and country (Argentina) and it does not work either. Now I put Android 10 (Canada) and it doesn't work either.
Please help!
Thank you,
Dreamer.-

This happened for me when I broke the back panel.
If you press on the reader and it works, that means there is a lose connection. You will have to fix the back panel.

My V40 did the same, so I had to send it in for warranty repairs. It was a hardware issue for me.

I already resolved it! The solution was to flash it to version 8 of Android, which was the one with which the cell phone came and then I flashed it again to version 10 of Android and the problem was solved !!

Question Andoid Auto

Got my Fold 3 a few days ago. Got is setup and plugged it into my truc,k and my Android Auto unit reads "No Device'". My Note 10 works fine but not my new phone. My headunit is a Jensen (like I said, worked fined with my Note 10). The Fold3 works find in my Nissan (Pioneer head unit) and my Edge (factory Ford Sync).

I am no expert here, but when I had a similar issue. I believe it is because I transferred everything from my prior phone to the new one. I got the same error when trying to pair my phone with wireless Android Auto in my Kia K5. My solution was to goto Google Play Services and clear the cache there. For some reason that allowed my phone to be found by my reciever. and worked. I didn't experince this with my new ZF3 but I did when I got my Note 20 Ultra last year. So try clearing the cache in Google Play Services.

Hey so try clearing the cache in the Google Play Services app. This worked for me when I had a similar issue with my Kia K5 going from Note 9 to Note 20 Ultra. I got the same error no device. This was going to a wireless head unit for AA. I finally figureout how to clear the cache in the Google Play Services app. Then went back to connect and it worked. Try this. It may work for the ZF3. Thankfully I did not have the same issue going from the Note 20 Ultra to ZF3. But this is what I would have done.

Thanks, man. I did that and to no avail. My phone is still not being recognized by my truck. When I press "Android Auto" on my head unit, I still get the message "No Device"

I'd flip cables for sure. Then I'd go to your setting when plugged in and make sure it's not set to charge only on the phone. Should be adjustable from the notification on charging.

I've having some weird issues with android auto and my fold 3. I've noticed when connected to android auto I often loose cellular data and it switches from 5g/lte/edge and no service. If I disable android auto the phone operates normally. Anyone else seeing anything similar.

Just a thought for OP. Did you happen to try opening Android Auto app in phone and checking to see if truck is an added vehicle and add if not?

The cable seems the most viable option. There is no option to select or deselect charging only, and Android Auto is no longer separate app. It is built into the OS and automatically opens when the phone is plugged into a headunit and there are no options to manipulate. The pain is that the dash has be pulled out to change the cable so I'll have to research a certified cable.

Did you buy chance to to settings > advance settings > then use Android auto there? Not sure if a setting in that will help. When I open it it wantsto attempt to connect to vehicle

When I go there, I get the button to connect to a car, but when I plug the cable in, nothing happens and the head unti still displays no device. I'm thinking that I'm going to have to remove the dash and change the cable.

Ah well unfortunately don't no more than that, just knew I saw an android auto option in there. My car doesn't support wireless and haven't tried the wired part yet to see

Well, removed the dash and head unit and changed the cable. I tried a Belkin USB-C certifed cable and even the known working cable from my other truck, and got the same thing.
On the phone I get the notification to stop my truck and apply the parking brake to continue and on the head unit I still get the notice of "no device" when I press the screen for Android Auto. At this point, I'm hoping I don't have to change my head unit to get this setup to work.

Weird mine worked just fine.
Did you make sure everything was updated

Yeah. I called Jensen they say it's a phone problem, Samsung says it's a Jensen problem

Got an email from Jensen customer service. My HU uses a bypass to allow certain functions while my truck is moving. I installed the HU myself and also installed the bypass. Jensen engineers found that I need to disconnect the parking brake wire from the bypass and connect it to chassis ground. I did that and was able to connect. I'm so happy to be able to use my phone in my truck.

Question Mi smart pen problem "K81 CS(DFU)"

Hey there everybody.
So I was using the stylus normally until the firmware update shows up, after a error on update the pen doesn't show up any more. I already tried to restore/restart the tablet and Bluetooth but without any success.
When I attech doesn't show anything, but when I remove pop a notification in red "charge your stylus now". BTW it already was in 100% b4 the update error.

Update: Apparently it's now showing as "K81 CS(DFU)" on Bluetooth and when I try to pair it says "couldn't pair with K81 CS (DFU) because of an incorrect PIN or pass key"

I have the exact same problem...any solution found yet?

Had this problem when i tried to update 1st time my gf Stylus on her tablet, first i tried with the (original) magnetic cover on and the stylus went onto DFU mode, i pressed on the button closer to the tip for about 10 seconds and the stylus went to normal mode(if i recall right). if this doesn't work try maybe the second button, or both at the same time.
Then i updated the stylus on my tablet without the magnetic cover.
Later received my own stylus and did the update procedure directly whitout the magnetic cover.
If the above doesn't work try to deplete the stylus battery, don`t connect the stylus to the tablet and leave it alone. i don't know the exact time it will last, maybe two days, or maybe a week or more, it has a tiny battery (25 mAh).
If succesfull reboot the table once, be sure to have the stylus linked but not attached to the tablet to be extra safe.
Good luck.

Hi there.
Unfortunately it doesn't work.
I left the battery dry and did all the rest, but when I try to connect to the pen in dfu mode it says "couldn't pair with K81 CS(DFU) because of an incorrect PIN or password".

Okay for some magical reason it worked today.
B4 I tried all the things again I opened the " service & feedback" app and started a "get Bluetooth log" and for some unknown reason it worked.

Thanks, but this solution is for those who can connect the pen but cannot update the firmware.
In my case, the pen doesn't even connect to the tablet anymore, so I can't change the contact sharing permissions.

Hey guys so I tried multiple message and I finally got it working.
I reseted the Bluetooth and Wi-Fi preferences.
I tried to hold the front button for 10 seconds.
I tried holding the back button for 10 seconds.
I called xiaomi support and they told me to reset the Bluetooth on Wi-Fi preferences and so I did that. Then I got a notification that my xiaomi pen update was complete and I noticed that now it was connected to my tablet.

Anyone else who didn't have luck by their side?

Still have the same problem. Showing k81 C's after update my miui to 13.1.3. any other suggestion what to do to fix it

how to solve this problem k81cs(dfu)

I got the same problem with the pen who appears as K81 CS(DFU), i'm trying a lot of things, but nothing works. If anyone got an other tip :/

I keep getting please chatge your stylus now eveen after 100% fix this so annoying

Same problem.
Mi Pad 5 global version 13.1.5
Mi Smart Pen was purchased from Amazon.de - and recently turned with "K81 CS(DFU)" issue.
There is no way to update the firmware as the firmware update is disabled. Attaching and detaching pen reports "Charge your stylus now" so there is some communication going on between both devices.
I've used the service and feedback to send the logs. Tried all workarounds described on XDA forums, nothing seems to help.

there is a lsposed module named maxmipad it removes bluetooth authentication so try it i dont have the pen
