[Completed] Big Problem with Bluetooth After Android 4.1 - XDA Assist

For nearly a year we have not be able to upgrade our 1000+ Android devices operating with 4.1 Jellybean because the Bluetooth will not work properly. We recently discovered that this problem apparently began with Android version 4.2, coinciding with the change in the Bluetooth stack from BlueZ to Bluezoid. Here is the story: We use an Anoto digital pen with bluetooth and an app installed on an Android device (Kyocera Torque cell phone). After pairing the pen with the phone, individual transactions, written by the pen on paper are sent to the phone after a "send" box is checked. The phone then responds by activating its camera, pictures are taken then pen data and photos are sent to our server. This is the process which has been working flawlessly. The problem: After 4.1, the pen must be paired then the phone restarted. The "send" box must be checked twice before phone responds. After 8 sends, the process reverts to the correct process and remains until 20 total "sends" upon which the bluetooth function stops. The phone must be restarted. The pattern repeats. We have tested this on a variety of devices using Android 4.2 all the way to Marshmallow, all with the same results.
Please advise as to where we might to go or with whom we may consult to resolve this problem. Our engineer is very capable and is hoping we can find someone who can help us find a work-around or hack without having to re-install the BlueZ stack, which if it is possible is likely a very big project.

[Q] CoreDroid 5 and Bluetooth

First, I hope I am in the right spot. I am looking to get some help with a Bluetooth problem. I love the rom, but I am having some issues with bluetooth connectivity. I do not recall which radio I am using, nor do I know how to tell. The rooting process was somewhat of a blur.
Problem Details:
Bluetooth pairs with my car exactly as I would expect. Transfers the entire contact list to my car's internal phone book (after a security warning). This works perfectly (waaaaay better than my iPhone 3GS did). However, when I get in the car to leave, the bluetooth connection rarely happens. I get a connection failed. Sometimes I can manually re-connect, but lately I am having to reboot the phone. Once rebooted things usually work. I am also occasionally getting a Force Close on the "Phone" app when dialing from the car.
I first used attn1's hack kit and used the current CoreDroid which was 4.7. It had the same intermittent connect issues, so I updated to the latest version. This version actually seems like it could be a little worse.
Any suggestions? Please let me know what additional information you may need.
Thanks

Hi bfrd,
Welcome to XDA.
Unfortunately this is not the right spot to post your question. What you should have done is searched the CoreDroid thread for the issue you're having and see if there is any info about the problem you are having. Here is a link to the search results for "Bluetooth" in that thread.
http://forum.xda-developers.com/search.php?searchid=65753748
If you can't find what you're looking for via searching then post a question in that thread of the rom you are using. The Development sub-forum for any device is for Dev's to post or for the occasionally helpful instructional post. Otherwise you should post rom specific questions within the rom's thread and non rom questions in the General sub-forum.
Good luck with your problem and happy searching.
please post in the appropriate rom thread..thread closed.

NEC Terrain Rooting and Flashing Guide

I am starting this thread to be a place for Terrain owners to come for the latest info on how to root and flash their phones. The Terrain is one of the best "rugged" phones on the market, but it has been abandoned by it's manufacturer, leaving owners to find their own solutions to problems and upgrades. This is actually a good thing price wise as you can now buy a brand new Terrain for less then $85. The Terrain has about as of hardware specs as any other ruggedized smartphone on the market currently, but at one third or a 1/4 of the cost. This makes this phone a huge attraction to anyone who is looking for a rugged waterproof phone on a budget and is why this guide is essential for users.
The NEC Terrain still has plenty of life left and this is why we need to come together and find solutions for it. Please feel free to post you success stories in rooting and flashing your terrain to this thread for the benefit of all. Hopefully, will be able to form a complete guide from all the information that get's posted here.
Thanks.

Thanks for the post and the links. It appreas that much of the information on these links are still a work in progress. Hopefully this work will continue and we can create a How To guide from this.
For those that may be interested. You can buy the NEC Terrain Unlock on Amazon for $79.99. Here is the link.

Well, I almost bricked it few days ago. :good:
I read a thread about a patch to unlock GSM in CDMA phones and saw there a code to enter some hidden menu. I entered that menu and messed a little with band settings (wanted to get LTE to work with my operator). Next thing I know Terrain stopped receiving any GSM signal and for next hour I tried to fix it. Factory reset got me 2G signal and that's all.
It turned out that the only way to fully fix it is to re-flash firmware or radio module and as we know that can't be done.
Well, this is not about unlocking or flashing, but it is a solution to another problem I and many other have been having with the predictive text bar blocking critical function keys from being accessed. The predictive txt bar is a function of the Adaptxt keyboard app and disabling it does remove that bar, but the keyboard also loses all special character function, upper case letters and numbers. After trying more then a dozen keyboard apps to replace adaptxt, I found one that works and brings back all keyboard functions without the stupid predictive text bar. It is called TouchPal.

Forgive me for this slight OT-posting, but it's not that easy to find people with this device - let alone an unlocked one. I'm located in Germany and the device runs just fine - except for the fact that Tethering does not work - neither USB nor WIFI. The PC can connect to the phone, however the connection in Windows 7 always is shown as being limited (no internet access), while internet on the phone works fine.
GMail - as well as some other functions of google also rarely sync and basically just do so on request, while they sync just fine when being connected to Wifi. And no, background data are not restricted in the settings.
Has anyone experienced something similar?

Well actually I know that message as well. For me changing the APN helped. You could also try to restart the phone. I just remember I also had this problem sometimes. But like I said - even without that particular message I would not get tethering to work.
iDomino: Do you also experience the problem with syncing that I had?
That's funny, actually I haven't noticed syncing problems untill I read your posts. I myself have all the same problems that you mention.
Even more of that, Terrain has some silly feature that TURNS OFF WI-FI if it thinks that that hotspot has no internet connection. It is massively annoying and can drain all your data traffic. The only solution that I found is to install the app "Smart Wi-Fi Toggler", it constantly turns wi-fi on if terrain turns it off, but only in places where I turned wi-fi on myself (like home and work).
It's a pity the phone has so many flaws and due to its tight security and the locked down NEC mobile devision no one can do anything about it. I wonder if this just affects the users who use an unlocked phone outside the US or if people in the US have similar problems. I have tried contacting NEC about this - actually about providing us with some kind of unlock mechanism - but all I got was this:
"Dear Sir,
Thank you for inquiry.
We, however, regret to inform you that our phone is not available about your request.
If you have any issue, would you try to contact the company or shop where you have purchased this model, who might be of help to you.
Thanks and Best Regards,
Fujii /NEC"
By the way, I discovered a new bug: When Roaming the actually used Network-Provider is not shown and I also didn't find a way to choose one...
Do you also experience the problem with syncing that I had?

I had some sync problems and I don't know working methods to fix it.
First time I solved it this way:
turning off apps sync -> open Gmail app -> it will show notification offering to enable synchronization -> use it -> sync works.
But this solution worked just once. (
Other time sync turns on by itself after one day disabled.
P.S. My Nec reboots while connecting via USB to ubuntu laptop.

Can someone tell me how your Terrains battery hold up charge? Because mine discharges completely in about 10 hours (without using phone at all). I think it's wakelock problem.

Does it crashes once or infinite loop begins? I had infinite loop problem while connecting NEC Terrain to Ubuntu, Linux Mint, Debian or CentOS. Removing "ModemManager" package solved it.

Another Terrain user here!
Hi guys!
i am Kharl
i am another Nec Terrain user here!
due my lifestyle, i needed a phone which could gives me reliability and power under ANY circunstance, that could be done by any rugged phone, BUT i needed querty keyboard, fm radio, gps, gyroscope, accelerometer, loud speakers, that could work worldwide and touchscreen... the only one with those features was the Terrain... and with the extra, that it is amazingly cool, i dont know opther but i find this phone really cute, very sober and elegant design.
well, i live outside USA so, for me, to work it couldnt be locked to ATT, so i was able to get one unlocked.
my phone has almost all the problems you mentioned, althught i am still happy with it and i am not going to change it because its problems does nto interfere a lot with me, BUT of course id like to get those problems sovled.
trying to solve the problem i bough three of thes phones and all the three had the same problems
the first one was by mistake, locked to att, but it had the same problems, random restart and locked hotspot, i sold it, i got a second one, works with any sim, everything fines, but with the same problem, random restart and no hotspot, i bought a third one to see if the problem was with my particular phone... and n luck the same problems.
it has some other minors problems, like no stereo audio recording despite it has two mics and IT STATES IT CAN record in stereo, but thats not a problem, i can deal with that, and sometimes the people at the other side (while in a call) says my voice sounds like from within a box (lack of trebble or too much bass) and when i press the check too much to the phone boddy there is also clarity sound problem.... but thats ok....
regarding the two main problems
random reboot and hotspot
many of us suspect what the cause is
for the random reboot many could think it is a installe app which is causing it... NO, because it does it at factory state, to solve that i dotn think root is needed, there is a certain factory process that is causin to reboot, the reboot is VERY random, could doit threee times in a day or could happen only three times in a week, what i have notice is that it happe lessoften in cold weather.
the hotspot problem IT IS cause because att locked that function, even when the phone is ulocked, that part remain locked because ATT.
what about you guys?
u can try hard reset for begging

Bluetooth Connection Problems with Garmin Vivosmsrt HR

Hello again,
after my themes problems at the last time, I have a new problem and I don't found a solution. The problem is between my Honor 6X and my Garmin Vivosmart HR/Garmin Connect Mobile. I use these combo round about a half year, with some little (normal) problems. If the connection is gone, I restart my phone and everything works normal.
On Thursday evening, the connection between my phone and my Garmin is gone. I try on Friday everything.
These are the things I try
- Reboot the phone
- ‎Reboot the Garmin
- ‎clear cache and data of the app
- ‎Factory reset of the Garmin
- ‎uninstall the Garmin app, reinstall
- ‎Factory reset of my Phone
Nothing helps...Now the problem is, that I can't pair the Garmin. The Garmin shows a pairing code, but the code is after 3 seconds away. In that time I don't have a chance to type the code in the phone. After 3 or 4 tries the app said, that there is a problem.
Now I don't have any more idea.
A try with my Huawei Mediapad M2 tablet works. That connection works.
Other Bluetooth devices (speakers, earbuds) are working.....
Have someone an solution ? I'm a little bit frustrated about it.
I had a similar problem just yesterday. I was unable to pair the 2 devices due to the possibility to insert the code before the possibility goes away (exactly as for you). I was able to do the pair restarting several times the 2 devices, turning off and on both Bluetooth, waiting until the possibility to insert the code didn't vanish after few seconds. But then I had another problem: the Forerunner was not reconnecting after loosing connection due to devices separation.
Here my lucky attempt starting from scratch (unpair and reboot both devices): ***on the phone I set the timeout for visibility to all devices to infinite*** (initially was 2 seconds).
Here the magic: I was able to pair the 2 devices without issues, I can even separate them and when they are insight the connection is immediately recovered.
Hope this help.
Cheers
Ok, I will try it. The first fast try didn't work. So if it doesn't work, I will take a look to the new Huawei Mate 10 (lite)
I have installed the firmware new, but that is not the solution. I can't understand what the problem is. It is a very scary thing.
So, after many trys I am frustrated....It didn't work. The Honor an Garmin Support doesn't reply. What I try is the bluetooth connection to two cheap Fitnesstracker (under 20 Euros) and they are working without any problems.
Same here. The pairing code is gone after some seconds and a new one is generated, making it impossible to pair the devices. Anyone who has an idea? Worked just fine with my old Xperia Z1C

Even miracast is problematic most of the time
Thank you for sharing your experiences. This doesn´t make me very optimistic...
Hi, I was able to pair my Honor 6X with my Garmin Fenix 3 HR, after many tries, using the various suggested techniques (restarting, leaving visibility on etc.)
It appeared pretty much like a lucky moment to have been able to pair.
The connection is however not very reliable - the two devices disconnect from each other frequently and do not automatically reconnect.
Very frustrating.
On different forums I read that many people are having problems with the bluetooth of the 6X, not only with Garmin trackers, but also with Fitbit.
Apparently there will be an firmware upgrade to the next Android/EMEI version by the end of this year, or beginnning next. I hope that will fix the problem.
I would be grateful when someone has a fix, but for the moment it looks like it is a known problem/bug, without fix.
I just bought a vivosmart HR+ and have the same problem. Has anyone tried to downgrade to 4.1 and pair the device? I'm curious if this would allow it to pair, and then if the pairing would survive the update process back to 5.0. If no one has tried, I might give it a shot this weekend. I lucked upon this device at my local Target as "rapackaged" for less than half price ($85.00 as opposed to $179.00).
As far as bluetooth problems with the 6X goes, I've experienced problems with a Pebble Classic and my Android Wear Sony SW3. Both paired just fine, but would stop receiving notifications at random, making them unreliable at best. It seemed to only happen with the 6X. My previous S5, BLU R1HD, and work's S6 never gave me these problems. I too am hoping a future update solves this. I considered trying EMUI 5.1 from the ROM section, but users seem to be reporting other problems there that I don't want, such as reboots, etc.
I happened to buy a second Honor 6x for my wife. It came with EMUI 4.1 and I tried to pair my Vivosmart HR+, but had no luck. I couldn´t even get a pairing PIN in the Garmin app. It would just do connection timeouts.
So EMUI 4.1 seems to be no solution.
Good news: at the garmin forums, some user called fin.pimlico had a clue where to search for the error and came up with a procedure that worked for me.
but read for yourself:
https://forums.garmin.com/forum/on-...unable-to-pair-fenix-3-with-android-7-0-phone
Good luck!
Hopefully this will help me out. My phone is having to be sent in to the service center for repair some I bricked it. So when it comes back, I'll definitely give your a shot. Thanks.
Garmin devices are developed to pair through Garmin Connect, and not Bluetooth. If you open and close your bluetooth connection, and try to manually pair devices, you're going to have problems. Skip trying to pair and connect altogether, open the app, and do EVERYTHING through the app, NOT MANUALLY.
---------- Post added at 03:33 PM ---------- Previous post was at 03:30 PM ----------
When I say skip, I mean delete ("forget") any direct connections you've already established through Bluetooth between your device and your phone, and go for the "Garmin Devices" option in the app, tap on "Add Device" and follow the steps until you manage to connect directly through the App.
@scolfaro
You´re right, but unfortunately this isn´t the problem we are dealing with here. The pairing of an HONOR 6x didn´t work from within the Garmin app. As I mentioned before, fin.pimlico tracked down the cause of the error and his solution of temporarily deactivating Wifi, GPS, and Data connection during pairing (from within the app) worked for me.

Thanks for posting this. My device came back to me today and I was able to successfully pair my tracker with my Honor 6X.
Well, the connection is flaky at best, I've had to repair twice already. I wonder if it will be better on one of the other ROMS, like Lineage OS....
I received an email from Garmin today that basically said that they've been working with Huawei and that the problem has been fixed. They said unfortunately, it means our device needs an update so we're at the mercy of Huawei to release the update. Below is a copy/paste of the email they sent me:
Dear Customer,
According to our records you’ve contacted us regarding connectivity issues with your Huawei phone and Garmin device. Please know that this is a very high priority issue for us and that we have escalated this issue to Huawei Engineering. We’ve recently been pleased to hear that their team has identified the solution to the problem but that it will require an update to your Huawei phone. We have requested an expedited release of this fix, but unfortunately at this time do not have a commitment from Huawei as to when this fix will become available.
We’ll be sure to keep you informed as soon as any additional progress is made on this issue.
Thank you for your patience,
Garmin Product Support
this is why I sold my 6x and got me a G5+ instead... not that that's any help, but still... super device, questionable software...

I tried to follow fin.pimlico's instructions scrupulously, but my Honor 6X will not let me proceed with Add Device without WiFi and Mobile Data being on. How are you able to do that? Anyone else get that error when trying to proceed with WiFi and Mobile Data off?
I was able to connect via Garmin Connect after uninstalling all updates to Google Play Services. I don't expect that connection to survive once Google Play Services updates again, as it unavoidably will. Hopefully, this will give a clue to someone highly skilled and experienced in Android inner machinations.
@NotNalb
I did it like "magi3x" in this thread:
https://forums.garmin.com/forum/int...rt-hr-and-huawei-p10-lite-pairing-issue/page2
"After the phone searches for the watch and asks you if you want to pair it or go on searching, I click "yes" and IMMEDIATELY minimize the garmin connect app and turn off Wifi, and GPS.
I return to GCA and wait for the pairing pin to appear.
Before I enter the PIN on the phone i return to settings and turn on Wifi and GPS again.
Back in GCA I enter the PIN, press OK and the pairing is successful.
I had to try this several times in order to get the right timing but in the end everything went smoothly."

Bought a first Android phone, not working as hoped - pointer for working it out?

I just bought my first ever Android phone, Acer Liquid Zest Plus.
It's not quite working in the limited ways I was hoping it to work.
First, I drive a Honda, which has handsfreelink system for connecting the phone to the car. The phone connects to handsfreelink ok, but then shows some weird behavior, in that when using the car's controls to place a call through handsfreelink, handsfreelink immediately apparently hangs up the call (i.e. the car's display shows that it hung up the call). However, this does not actually hang up the call on the phone itself, as the call gets placed nonetheless and when someone picks up on the other side, I can have a conversation through the car's audio system. Seems to almost work, but the weird behavior just described means that I can't hang up a call without pulling the phone out of my pocket and hanging it up from the phone (as opposed to hanging up using the car's controls) while driving, which takes a lot away from the point of it all.
What could be the issue with this? Note that I had a Blackberry Passport before, which used to work all as intended with handsfreelink, and my family member's iPhone 7 Plus also works as intended with handsfreelink. Is it that my Acer Liquid Zest Plus does not have the necessary bluetooth profile/stack to works with Honda's handsfreelink? Is it that handsfreelink proprietary to Honda and uses something unique, as opposed to being a generic bluetooth device of the kind? Is a bluetooth device link this, used by other auto manufacturers, feature the same generic bluetooth thing, or is this something only Holda can possibly answer for me?
Could updating the phone solve this issue? If so, how? I go into Settings -> About phone -> System updates and it tells me that my device is up to date (I did not update it since pulling it out of the box). I notice that it's on Android 6.0 , and a quick Google search showed some discussions that it is highly unlikely that the phone will get newer Android update. The "Android security patch level" shown in "About phone" says December 5, 2016. That's a long time without a security patch. Should I, and is it possible to, update the phone?
I've heard of rooting an Android device and installing custom Roms before. Where can I find a guide for my device and the custom Rom files? I am hoping this might solve my issue with handsfreelink.
I know I am all around the place with my questions, but essentially, the issue I am having is that bluetooth connection to my car's audio system does not work as expected, and I am wondering how I might fix it. I am wondering if an OS update (either official version by manufacturer or a widely-used custom Rom) might solve this issue, or simply adding an extra bluetooth profile to the phone.
A solution would be awesome, but I'd be asking too much if I was hoping for that. Instead, if anyone can just provide me some pointers in terms of how to do research on what I should be doing to solve this, or clarify some concepts (to the extent you can tell I got it wrong from reading this post) for me, it would be really appreciated.
I've already been to Honda's handsfreelink website and Acer's support page for this product and there's nothing helpful there.
Thank you very much.

Question Winca S310+ (UIS7862) Android 10 hardware and firmware support, Q&A

Hi guys, I'm urgently looking for support for the Winca S310+ on FYT platform (UIS7862). Maybe someone can help with the following information or has similar problems.
I will work on the S310 issues over time and post updates as appropriate. Perhaps one or the other contribution will prove to be helpful. In this case, please leave me a thank you that motivates me to keep going. Of course you can also help each other.
And by the way: Sharing firmware and MCU is expressly desired.
Are there custom firmware for these devices (custom ROMs)? The OEM settings are kept very short and concise.
Is it possible to get the MCU of these devices as a backup (and also newer versions)?
Are there technical data sheets for the wiring harness? I am looking in vain for an AMP cable for the amplifier. Also, I can't understand why an external Bluetooth antenna is needed and only one 4G antenna can be connected (the sp9853i had 2)
The inserted Vodafone SIM card does not go into operating mode. The reception bars appear, but they are blank. The PIN query of the SIM card does not appear and cannot be deactivated.
There is a loud bang in the speakers each time I start and exit the radio app. I've observed the same thing when streaming via Bluetooth when changing tracks. The bang is so loud that it scares you while driving and it does not depend on the volume set. I made a short video of it where it can be heard very clearly several times. Maybe someone has an idea what could be the cause?

The Canbus does not work reliably. Sometimes the radio stays on and continues playing music after the ignition is turned off and the car is locked.
I can't sign in to my google account. The login window for entering the e-mail address appears, but immediately afterwards the application always closes unexpectedly. App updates have been done as much as possible.
Attached is information about my system.

UPDATE:
The last issue #7 was fixed by a firmware update, which I received from Winca.

UPDATE:
This issue has also been partially "fixed". Unfortunately, there is still no SIM PIN request from blocked SIM cards. The SIM PIN must first be deactivated in another smartphone. Then this also works in the S310 with mobile data.
CAUTION, PLEASE NOTE!
The unlocked SIM (currently no PIN) can be redefined in the S310, but after the next reboot, as mentioned, no PIN query appears and the mobile data etc. do not work! For some reason, this setting cannot be undone in the S310; the SIM PIN must be deactivated in another smartphone for this purpose!
The SIM PIN request is said to work on systems with an active lock screen (screen lock), but I haven't tested that yet. However, on my old system (sp9853i) the PIN request worked even without an active lock screen.
