Loss of data connection and GPS......could this be caused by overheating? - Nexus 6P Q&A, Help & Troubleshooting

I have a weird problem.
I frequently run a combination of SiriusXM, Google Maps (navigation) and ARU Rootless (mirrors my screen onto my car's Pioneer head unit so I use the head unit's bigger touchscreen to view and control the phone). To use ARU Rootless, I run a hotspot which connects to my Chromecast on the head unit, casting my screen to the Chromecast.
The problem is that eventually I will get a notice that GPS stopped working, and at the same time, I've noticed that my data connection completely drops as well. The screencasting and audio (stored on the phone through SiriusXM On Demand, so it's not using a data connection) continues to work and I can still make voice calls, but I can't regain my data connection or GPS until I reboot the phone.
Running all these things at once gets the phone warm, but not so much that I think, "Damn, that's hot!". I have not experienced any reboots.
Lately I've suspected that the problem might be related to overheating. I've taken to hanging the phone off my car's air conditioning vent to keep it cool, and I think I've noticed a definite improvement. I'm about to leave on a 2 hour drive and will test it again.
So.....is the simultaneous loss of GPS and data connection possibly related to overheating? BTW, my carrier is T-Mobile, but I'm not hitting my data limits so throttling is not at work here.

[Q] WiFi + Bluetooth = Fail?

I received the Nexus 10 32gb on Friday and have noticed the following problem:
When I have WiFi on and my Bluetooth controller connected, the WiFi and Bluetooth signals will completely shut off and restart consistently within a 5-10 minute time frame. I have seen posts regarding WiFi problems and also general Android 4.2 Bluetooth problems, so I am not sure if this is related, or perhaps more insight into what is wrong with these units (or at least mine).
Has anyone else experienced this?
What I am doing specifically when this happens is this: WiFi is connected to 5ghz router signal, Bluetooth is turned on and paired to a Nyko Playpad controller (BTW, the paring is way more finicky than with my Note 10.1 which I am trying to replace with the Nexus). I then start playing a game with Mame4droid Reloaded or Nesoid and consistently within about 5 to 10 minutes, the controller will become unresponsive. If I go back to the home screen when this happens, I see the WiFi icon is now only an outline (no blue or grey signal bars in it), then the Bluetooth icon goes from blue to grey. Then, after a few seconds they both come back on and I have to re-connect my controller.
I haven't noticed the WiFi dropping in general use, and if I turn off WiFi and use the controller, it seems to not disconnect/drop out.
Update: Last night I watched a full 2hr NFL game streamed through NFL Game Rewind and at one point playback stopped. The WiFi indicator turned grey and I had no internet connectivity (couldn't even open any sites in Chrome). I turned off WiFi and when I turned it back on again, it just hung on "starting WiFi"- or whatever it says and there was no list of available connections, etc. I had to power down and restart to get it back up.
Then, I used the Nyko Bluetooth controller to navigate the menus and some apps to see if it would disconnect as it does when gaming. Same thing happened- both WiFi and Bluetooth connections cut off and restart...
I am obviously returning this unit, but I hope to see if the same thing happens to anyone else as far as WiFi/Bluetooth is concerned. No one else has used a Bluetooth controller effectively with their Nexus 10 yet?
I have seen complaints for this same issue on the Galaxy Nexus forums. Seems like they think it's a Android 4.2 issue.

[Q] Bluetooth not working

Has anyone experienced that the Bluetooth completely stops working on this phone?
It seems when a certain bluetooth device gets out of range from the phone and momentarily reconnects, while this process happens for quite number of times.
The Bluetooth seems to stop functioning completely until the phone is rebooted.
That is to say, the bluetooth menu and on/off switches will appears to be working but none of the paired bluetooth devices can connect to the phone.
The Scan function in the Bluetooth settings page also becomes useless where it will appear to be scanning but will not find any near by devices.
The same with that check box "Tap to make visible to nearby devices", another device will not find the phone's bluetooth signal.
It looks like the kernel module for bluetooth radio has crashed, after prolonged period of paired bluetooth devices DoS the phone's bluetooth with very weak bluetooth Connect signals (when it becomes out of range)......
This bug seems to be problematic because whenever I have my devices charging in separate places this problem start to appear within a few hours after charging.
Most of all this is very annoying because you will need to reboot the phone to get bluetooth to function again.
And I will not factory reset my phone just because of this annoyance.
It looks like that there's a major issue in the hardware or kernel itself.
This problem started happening when I got the Asus ZenWatch. The problem is apparent if the phone and the watch are almost out of range to each other but repeatedly reconnects once in a while.
This looks very much like the main reason for crashing the Samsung Galaxy Note4's Bluetooth Kernel module...............
I am making the assumption that the Bluetooth Kernel module has crashed because another device does not detect signal from the phone's Bluetooth radio.
I have same issue with my SM-N910C variant, simply BT doesn't turn on.
bluetooth shuts itself off after 2 minutes. you need to check the box again after 2 mins. annoying but not the end of the world.
existing paired devices pair normally regardless. ive never seen it crash or freeze.
The bluetooth on this phone is terrible. Quite honestly, this is my only gripe about this phone. I have to connect/disconect bluetooth several times in my car before it stays connected. While connected, every few minutes the audio will drop out for approx 2 seconds and then come back on. Also once every few hours right in the middle of streaming audio while driving, for no apparent reason, the phone just decides to disconnect bluetooth altogether. Very Very frustrating.
I'm having the following dmesg messages related to bt init:
01-18 12:04:50.748 19152 19164 E bt_upio : set_bluetooth_power : write(/sys/class/rfkill/rfkill0/state) failed: Operation not permitted (1)
01-18 12:04:50.748 19152 19195 E bt_hwcfg: Start CFG HW, HCI reset
So sad that there is not a solution right now.

The problem was the range and a weak or intermittent signal.
Since I changed the leather band to a stainless steel one which I believe boosted the watch's bluetooth coverage.
This time the phone's bluetooth does not go down anymore.
Now, I am not sure if the watch's coverage or antenna too short causing this issue.
Or something wrong with this phone's bluetooth...

Bluetooth suddenly stops working and can't be turned on again - fixed only by reboot

Hello folks,
i atm i am Running RR 7.0.2 and having the problem that my bluetooth is disconnecting/reconnecting randomly in an interval of ~20 minutes in my car and nearly every day the bluetooth service on the phone completely stops working and then i have to reboot it to get it back working again. It's deactivated on the phone then and can't be activated, neither by the button on the pulldown menue nor in the settings.
My issue seems to be similar to the problems these guys encountered:
https://forum.xda-developers.com/galaxy-s5/help/oreo-bluetooth-t3851777
https://forum.xda-developers.com/galaxy-s5/help/bluetooth-off-randomly-t3971491
Is anyone maybe having an idea why i am experiencing this behaviour or how to solve this issue?
Upgraded it to Resurrection Remix Q and the issue is gone so far, but my daily driver is now a Mi 10.
Many years ago and when my phones were Nokia S40 or Symbian, i had quite short on - off intervalls, every 5-10 seconds.
In this case here i suspect that you have just bad signal reception.
The connection between my S5 and my new car OBD adapter occasionally dropped until i switched from BT4.0 LE to BT 2.1. Stronger signal.
In such a case(phone on the dashboard, adapter below and metal in between) a direct connection may be impossible, making it depend on signal reflections from the chassis. Connection to the headunit was always stable, the radio sits atop the EOBD jack, and this alone may shield the adapter from the phone.

Bluetooth problem

Hello to everyone.
From when i bought it the op8pro has some problem with the bluetooth. Is like if the device can connect to one device only. I have a fossil 5 gen, one fiesta mk8 with android auto and the bluetooth headset but is like if the bluetooth has some problem to connect to two or one devices. For example every time my car doesnt connect to the phone automatically and today when i was to the gym my headset doesnt connect automatically too. My previous note 10 pro was able to connect without any problem... Someone has some problem with the bluetooth? Thanks
I have another problem. Every time that i enter in my car the device is connect to android auto but if i want to play an audio from whatsapp i have to tap a lot of time on the play botton.!!!???why
I see this same issue, I'd say 80-90% of the time (the other 10-20%, it "just works", which is truly odd, given the protocol).
For example, I use some bone-conducting open-air headphones, while cycling (long time road cyclist), and sometimes I want to connect my Garmin Edge 1030, to download a route, when I'm out.
Good luck, even upon returning, I'm often sitting in the garage, trying 20+ times (after shutting my headphones off, even), to try and download my ride-data, for the day. Sometimes it requires rebooting both devices, flushing the Bluetooth app-cache, and the Garmin app-cache, and then it'll work, that's perhaps 40% of the time.
For another 40%, it will NOT connect, what-so-ever, across multiple reboots and app-cache flushes, period (I tend to give up at around the 20+ attempt mark, depending).
The last 20%, it works, perfectly, as you'd expect, and as my OP7 Pro did, I can't recall a single BT connectivity issue, with it, either solo (Garmin) or with headphones concurrently.
I've filed bugs with OP (along with NUMEROUS other radio bugs, like the fact you can't connect to a 5G-mobile signal, if you're connected to a WiFi signal, on the INO2025 model, bug filed, trace-logs submitted, including pointing out log-lines where the radio(s) fail).
Unfortunately, with the Bluetooth issues, it will not repro, if I use the OP debug-mode, which is how they want to receive logs (and how I've submitted many bugs, previously), so I'm at a loss, short of finding a hardware Bluetooth debug module (I used to work on h/w and s/w boundary driver stuff, so I've used a h/w BT debugger before, but not for some years, and have no access to one, currently).
OP seems to just ignore the bugs, at that point, when I can't provide the logs, they pretty much abandon the bug-thread, so I'm not sure how they're going to get some of these resolved (I've noted that the debug-mode seems to introduce some latency, or similar, that prevents repro, no response to that, what-so-ever).
I have reset the radio-stack, a couple of times, and did one full factory-reset (shortly after getting the phone, about 1 month back now), with no real change in results, for reference.
I feel like I'm back in the late-90's, when Bluetooth was super-flaky. on most devices, in the 1.x and 2.x days.
Not exactly a "flagship phone experience", or even a decent budget phone Bluetooth experience, for this day and age...
I'm open to ideas on how to debug further, I'm really more of a storage and display guy, and memory-management, in terms of the bulk of my dev/debug skills, communication protocols were something I did on the fringe, of sorts, when they overlapped, or similar.

Help with using navigation on an Xtrons HU

Posting here as I think I used the wrong secrtion previously
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)

First of all you need to fix your FM reception. You need to use a phantom power adapter to get some voltage to the OEM antenna.
There are some navigation apps which don´t need a internet connection. TomTom as example and others using offline maps. But you won´t get traffic messages if you don´t have an internet connection.
That would fix your white noise.
The FM radio can be closed if you use the back button on top right. If that does not help, chose the recent apps button on top and swipe the radio app away as for each other app... You really should learn how to use Android.
The navigation loudness can be set in the system settings. Depends on the unit where you can find it. In this case the navigation software needs to be registered as navigation in settings /Apps/Standard apps.
Regarding your 4G-WiFi dongle... The name itself shows the functionality.
It connects via 4G to the internet and provides the connection via WiFi to anyone in the car.... even too to the radio.
The GPS slot on your radio is nothing else as a micro-SD slot, which also can be used to store music on it or whatever else you want.
BTW: Seems that you are not that familiar with car electronics. May be a good idea to ask someone who can help you with some knowledge what has to be done.
Might be an easy task to just swap a radio, but there are more things behind than just swapping.
May I recommend 'Magic Earth' navigation, works fine with no internet but no live data of course.
At least there are a lot more offline navigation apps...

But without internet... no traffic data..

Thanks for a helpful reply. I have already fitted a power injector for the FM antenna which made some difference but I like to listen to radio 4 and there are parts of the country (along the M11, on the A5 in North Wales), where you cannot pick it up on any radio - and of course in Europe where I have just been for a few weeks where I usually don't want the radio on at all. That's why having the nav sound set as a percentage of the existing volume seems a bit odd as it implies you already have some other sound on. Better to have a dedicated channel for it or have the nav mute any other sound.
I'll look at doing all the swiping etc to turn off the radio by closing recent apps although this doesn't seen like a very safe thing to start doing when you drive into a area of poor reception. I was hoping the unit would have a simple press button like in the good old days!
The dongle info is also useful thank you. Xtrons do not make this clear at all. They imply that by plugging it into the socket on the unit you have made a (wired) data connection. If the HU is still only connecting over wifi anyway then I can install the dongle wherever I like in the car so that it gets a good 4G signal, instead of it having to be in the driver footwell at the end of the short USB cable xtrons supply and I can use a dedicated 2A usb adaptor to supply decent power .
I guessed the 'GPS' socket might have nothing to do with GPS. Shame Xtrons couldn't say what it was for instead of just mis-labelling it.
Incidentally. The SIM in the dongle would only ever be used for the navigation to receive traffic updates or bits of map or whatever it needs i.e I don't intend to be surfing the net or downloading Utube videos. Do you have any idea what sort of data requirements this would mean. Would a 250Mb a month sim be enough?
I'll experiment with your suggestions.

I'll look into those thank you. I use maps.me on my phone but couldn't get google maps to work on the HU as it said I was offline. Of course I still need an internet connection to download any of those apps and install them on the HU but I could just park near my house and using the house wifi.
Data plan for using navigation online data depends on the app you use and the amount of mileage per month.
You can use your smartphone first to see what you need in a "normal usage" month and then decide what you need.
If you use any offline map solution, it´s also some sort of usage dependency.
BTW... If you would invest into a higher data plan (2GB), you could use the app Radionator to use Online radio. BBC Radio4 should be in there too. Radionator is the best alternative if you want to listen to one specific radio station. Just needs a stable internet connection, nothing else... and the sound is mostly better than FM.
May be you can use the Navradio+ as alternativ solution for receiving FM radio. Depends on the MCU of your unit. Search for it in MTCD software forum.

I would recommend to use HERE WeGo, it served me very well for the years I didn't have mobile internet connection. Also it shows the max allowed speed in most countries, whereas Google Maps doesn't do that.
Sure, Here WeGo is a good choice, even without internet connection.
