Bluetooth not enabling on EMUI 5.0.2 - Huawei P9 Questions & Answers

Bluetooth isn't working on my P9. I've tried restarting the phone, toggling airplane mode on and off, checking that apps aren't automatically turning it off. I'm out of ideas on how to fix it. When I try to turn it on anywhere in the system, it starts off dimming as if it'll turn on, but then I either go out of the Bluetooth section in the system settings and see that it's still off, or close and reopen the notification shade and see that the Bluetooth shortcut is either still dimmed or still off.
My phone is model number EVA-L09, running EMUI version 5.0.2 and Android version 7.0.

I've got a slight idea as to a possible reason that Bluetooth isn't working on my phone. My idea is that as lots of the stock apps are missing, that could mean that some internal files could be missing too, such as the ones that would allow Bluetooth to work, or at the very least, turn on.

why does the h6515 power itself on?

question, i've got a 6515 and it keeps powering itself on. when i turn it off (with the on switch), it automatically powers on after a few minutes. this drains my battery within 18 hours since the pda function is activated (back light and screen comes on). it keeps powering on automatically every time i turn it off. i disabled all connectivity (no sim present, bluetooth of. so both are disabled). i disabled the gps download applet, so it cannot automatically download. i disabled the active sync setting (After setting it to manually and unchecked all the peaktime settings). i also tried to reflash my current rom (the latest), but it keeps powering on? i also took out all the memory cards and there are no third party applications installed (just did a hard reset). any help is appreciated, or else i will throw the thing out of the window (then i know for sure it will never turn on again)!
mine did the same thing for a while and it was related to activesync and blutooth ativesync. no idea what fixed it tho. sorry
Disable Hardware Buttons
Have you tried to disable the hardware buttons to see if it maybe a button that is getting pressed. To disable them hit Start, goto Settings, tap Buttons, tap the Lock tab, then put a check in the "Disable all buttons except power button" box.

Any apps to auto boot/shut down? Need help...

Whats up XDA.
So I have a galaxy tab sch-i800 running on cyanogenmod 9. I plan to fit my tablet into the dashboard of my car, I have everything worked out except how I'm going to turn it on and off. since I won't be able to access the power button I need a way for it to power on/off by its self, that way its not occasionally dead when I start my car.
At first I planed to use tasker to turn the tablet on when plugged in (or when I start my car, it turns on). and then turn off after an hour of inactivity (or an hour after I've turned off my car).
But now that I'm looking at tasker it won't let me use the command "turn on" (even though I'm rooted) and I don't see a turn off command.
Is there any apps out there that can help do exactly what I want?
I have noticed that 4.2+ automatically boots when it is plugged in, I'm on 4.0, would upgrading screw up cyanogenmod?
Thanks!

To Switch ON
I think you may have to rewrite the Bootloader code to switch ON the Tab when Charging starts instead on that Large Green Battery Animation. Search it ..
Hint : I have seen it(the code) somewhere while I was looking for OTG in P1000.
To Switch OFF
Try these apps and do post their results

What you hope to accomplish with it turning on from a full power off is not possible without rewriting the bootloader or somehow rewriting the power switch (open the tab, solder wires to the switch terminals, and use an external relay or transistor to short the wires).

[Q] Bluetooth

Yesterday my bluetooth won't turn on. It has been working good but all of a sudden you go to settings to turn it on and the on button changes color a little but not bright like it usually does and in an minute or so it will go back to off. The bluetooth logo never shows atr top of screen. Any help appreciated.
Added info. I googled and found that sometime a app. will cause this. I haven't recently installed a app and bluetooth has worked since last app install
L.D.
I have found if I shut phone down and restart bluetooth can then be turned on. However, Later bluetooth can't be turned in until another restart.

[Q] how to enable bluetooth at tizen first start?

I connected to Kies 3 and updated firmware. My watch had bluetooth off, and on restart with Tizen, the watch is stuck waiting to connect to the phone before doing anything else, but of course cannot connect because bluetooth is off. How can i turn bluetooth on?
Factory reset does enable bluetooth, so all was fixed. At first attempt it did not appear to work, but after a power cycle all went smoothly

I'm in the same situation as you were. Even after I turn it off and on various times, Gear Manager does not find it when scan.

If I turn off the car and turn it back on, android auto won't work

Hi,
If I turn off the car and turn it back on, android auto won't work. I need to restart the phone. With another phone where Android auto is not in developer mode it doesn't. Is that possible? At the first start everything is ok, but if I turn off and restart the car the phone connects only via bluethoot and not via cable unless I restart it and sometimes I have to restart uconnect as well. advice?
thanks,
Mariodm
