Hello, I have been turning mad lately since my Optimus 3D began acting weird once I connected it to my PC to transfer large amounts of data in USB MASS STORAGE mode.
In the beginning, the transfer was ok and connection didn't show any problem. However, at a given (arbitrary) point, it just connected and disconnected by itself several times in just few seconds.
I thought it was the usb cable, so I changed it, but that didn't fixed it. Then I tried it with several other computers, and that happened randomly on all of them.
Then I thought it could be the micro-usb connector being damage, but as I closely analysed it in the computer side, I found that the phone was connecting ok, but was recognised the wrong way. (drivers were ok, as I reinstalled everything several times)
In fact, the LG update recognised the phone's model and connection. It simply didn't worked as a mass storage usb device.
I spent hours searching the web for answers about this issue, but the only thing I could found was one guy telling to remove the battery for 10 minutes in order really reset the phone's usb mode.
I did it and it worked! HOWEVER, the issue reapeared quickly once I connected the phone to the PC via USB. (it took several minutes to happen, but happened)
I finally found this forum and read a lot of complaints about LG phones.
However, it seemed to be a software error, not a hardware one. Wich was good news.
I was thinking to send the phone to LG for repair, but I had little hope they would even check such an arbitrary issue with usb connection and I thought they would simply say it's my computers fault, so I kept searching.
I finally found a similar issues with Galaxy S2 on the forums, and someone fixed it accessing the "PhoneUtil" hidden app in that phone.
This app don't exist in LG phones, but there IS a hidden menu to fix this, but you will have to install a free shortcut creator app form the market place in order to access it:
- download "ANY CUT" from the market place
- run it and create a NEW shortcut
- select ACTIVITY
- scroll down and tap on: com.lge.hiddenmenu.port_setting.PortSetting
- give the shortcut a short name like "Port Setting"
now you have created a new shortcut in your home screen (somewhere)
Once you tap on it, a menu will pop and let you choose the type of connection to be used by the USB port.
By default, "NO RETENTION" is selected.
If you want to force the phone to use the usb connection for data transfer with your PC, then select AP USB
(if you check the "retain AP USB after reboot" it will freeze your phone and you will have to long press the power button to shut it down, but it will actually work and will be set this way until you change it again)
Voila! That fixed my LG P920 Optimus 3D USB transfering issues.
If you need to make a software upgrade at some point instead of using it for USB transfer, just change the setting to "NO RETENTION" again and check the "reatin after reboot" option.
I just wanted to share this, as I found no fix for my problem in the net and I think this should be happening to someone else.
Feedback is very welcome! (even needed, just in case this is braking something)
By the way, it's a good idea to activate the "Debugging mode for USB" in settings/applications since it seems to make a more robust conection with the phone for mass storage transfer.
As why this entire issue is happening, it seems the USB conection can handle multiple transfer modes. One of those is USB Mass Storage mode (like every pendrive out there) but the other one is a LG propietary comunication mode that I suppose was done in order to have full access to the phone firmware through the computer.
The bug appears in the moment when the phone have to decide if it should engage on mode or the other.
I have noticed (since I forced the port setting to AP USB) that the phones screen will turn itself on randomly once connected and that it don't stay active even if you specifically check that option in the development menu.
I suppose the original bug is still there in someway, but at least it will not ruin the data transfers.
Ok, just in case you don't want / can't make the shortcut for the hidden menu, you can use this method to access the full hidden menu right out of the box without any external app:
push the button to make a call,
now enter the number:
3845#*920#
This will redirect you to the full hidden menu. Once there, you can go to the PORT SETTINGS menu and set it to AP USB.
And if you want to upgrade with the LG software, you must set this to AP USB and make it stay. Then when you are upgrading, you must stay vigilant and press (and keep pressed) the volume up button in the moment it reboot the phone (or before it reboots, just to be sure)
This way, a white screen with red text "factory upload" will show and upgrades will have no problems.
(this mode normally only happens when you press the volume up button with the phone off, and then connect it to the usb port and there is an LG software commanding the phone via usb)
Hi,
i am trying to connect both devices, but the Smartband is not shown under android bluettoth settings. Unfortunately the Honor 6 L04 does not have NFC. But i doubt this would help.
I tried following things.
With the Apps "BLE Scanner" or "Bluetoth LE Scanner" i can find and connect the smartband. The apps say that its connected and the Smartband acts like it is connected (LED's).
Unfortuantely the Smartband Settings can only be accesed via Sony SmartConnect, but i cannot start Smartband Settings since it's not connected via android blueetooth menu.
I tried "adb shell am start -a com.sonyericsson.extras.SETTINGS" and the smartband settings menu appears, but status says its not connected.
Smartband is working (naturally) with a Sony Xperia Z and my Lenovo Yoga Tab 2.
Any ideas?
I found out that the Smartband settings are also accesible via Sony Lifelogger. Don't need adb shell method. Not connected either.
Also "BLE Scanner" says connected, but not bonded. "Bluettoth LE Scanner" says BLE Supported, connected but unbonded.
No suggestions everyone how to isolate the problem?
I would be very grateful.

I have no Sony Smartband but I have a Pebble and a Moto360.
I had big trouble to transfer Weather Data from my Huawei (H60-L02 rooted) to Pebble. And or Weather and location Data from my Huawei to Moto360.
The devices where connected well - and everything seems fine. But after a few hours - no Weather Data no location Data.
All settings in "Telefonmanager" check: StartUp Programs ok, Notification ok, Trusted Apps ok...
Nothing helps.
No I have freezed the "Telefonmanager" with titanium Backup. Everything is working perfect now!
The Problem with loss notifications from WhatsApp are history now
If your Device is rooted - try to freeze this App - and test again. I think this app will cut or prevent connections
Hi JimKnopf13.
I am not rooted at the moment, and i want to stay unrooted as long as possible for various reasons (warranty, etc).
My problem is that under bluetooth settings the smartbans is not shown/listed and that it is not bonded (with the Bluetooth BLE tools). Your's is that the connection is not reliable. Can you explain why i should freeze the "Phone Manager"? What's the connection between the two different cases?
ok, then it is a different thing.
I can see my Pebble and my Moto in the bluetooth settings. I can connect.
Only later, I think when the phone enter the sleep mode - all Data from Weather provider are blocked.
When I freeze the telefonmanager - everything working well.
Any developers here that can sched a light at this topic?
Each time I get into my car and connect my OnePlus 6 via USB, I have to change the USB connection type on the phone to MTP in order for Android Auto to connect. Once I change the setting and it connects, Android Auto runs well and stays connected until I turn off my car. Without changing the USB setting, the phone will stay in charging mode and Android Auto does not connect.
My car is a 2016 Honda Accord EX and I am using an OEM cable. The phone is rooted, developer options are enabled, and USB debugging is off. When I go into the developer options and try to change the default USB connection mode to something other than charging, the setting change doesn't seem to take.
Is there a way to automatically use MTP mode when I connect the phone to my car? Or something else I can do to get it connected without having to change a setting on my phone each time I get in my car?
I would clear data, force stop, and reinstall Android Auto. I use it every day and have no problems at all. Connects automatically.
My HTC M9 had no end of problems with AA. Would not connect half time time unless I replugged it in, and the voice-to-text function was buggy as hell. My OP6 is smooth as silk.
Thanks. I tried that and even deleted the phone from my car. It didn't work. I had to change the mode to mpt to get it to do the initial connection. Same for reconnecting. Doh!
Do you use Tasker? I wrote a task that will automatically change the setting to MTP. It requires the Tasker plugin - AutoInput as well.
I do have tasker. How do I set it up to do that? Thanks.

So I actually created two different profiles/tasks.
1) Detects when USB power is plugged and then opens developer settings and scrolls automatically to usb configuration and makes the change. This profile/task requires the plugin AutoInput.
2) Uses AutoNotification to detect when there is a notification in your tray stating that the device is being charged. Then it will use AutoInput again to click on the notification and change it to 'USB for file transfer'.
I only attached #1. Import it into to Tasker and see if that works. If not, I can add the second option.

God, it's annoying. It happens in all the modern androids. My S8+ 5T and now my OP6
My OP6 has no issues connecting to my Pioneer AVH-2330NEX. Just plug it in and AA starts right up. Bluetooth is pretty reliable as well, which is how I connect most of the time.
It usually takes a minute or 2 for my AA to come up on my screen (2017 Charger). Once it's connected, it runs super smooth. But I wish it was a little more responsive once I plug in the cable. Now I have to wait for it to come up before I can launch any app (Maps, Spotify, etc)
I"m going to see if the MTP method makes it connect "faster". If so, I'll look into building a Tasker Profile as well like @azsl1326

This is really close. I had to add one more scroll down step in the developer menu and change the mode to MIDI. It doesn't work 100% though. If the developer options menu is already open, it reopens wherever it was and sometimes the scroll down goes too far... Perhaps there is a more stable way to do this?
Attached is my modified tasker profile.

I have another profile that uses AutoNotifications to detect when there is a notification in the tray regarding USB charging. It will then use AutoInput to select this option from the notification tray and change it to 'Transfer files'. I can post that here if you are interested. It does require two paid plugins.
You could add a task to clear recents before running the AndroidAuto task - that way it should ensure that Developers Option screen is no longer active.

Here you go. I think both of these Auto plugins have free trials, so you should be able to try it before you buy it.

I replied to you in the other thread, OnePlus 6 and Android Auto
But to fix your issue, this MIGHT be the solution for you specifically. Setup an appointment with your local Honda dealer, and ask to get Technical Service Bulletin 16-059 installed.
This fixed my issue for my '16 Accord when AA wasn't working at all with my PH-1
Or you can just simply choose this option to mtp as default on USB connection. It's in developer settings.

I've tried this as well. The setting does not seem to stick. It sometimes works the next time I plug my phone into my car but the 2nd time I plug my phone in, the default in developer settings is back to USB.

This did not work when I tried it today. I'm guessing there is some difference on my phone that would require the setting to be tweaked. I'll look into this.

Didn't know that..
I had the same issue with a VW Passat 2016, and the solution was to enable USB debugging, and after that everything is working ok.
Unfortunately I'm facing another issue. If I'm initiating a call with the phone connected to AA, usually by voice command, the sound is routed randomly on the headset, speaker and sometime to Bluetooth.
Every time I have to set manually from phone app in AA on the car screen to route the sound to Bluetooth, and this is annoying. . Do you experience this issue as well?
Thanks!
I'm helping a friend who needs backup of her broken phone for an upcoming court case.
I need to extract all photos (camera, snapchat etc) and text messages (sms/mms).
The phone seems to be working other than the screen and touch controls.
Replacing/repairing the screen isn't an option as we both have minimal funds, and my friend has a new phone already)
i have "access" to the phone, but neither USB Debughing nor MTP is enabled so i cannot access any files.
I'm able to unlock it with a keyboard connected (i hear the little unlock click after entering the pin, and the "turn off screen" click when i press the power button.) But i have to navigate blindly, and any guide i find seems arbitrary how to get to settings, it says to press win+n (same as pulling down the quick settings menu from home) and press tab an arbitrary number of times to get to the settings gear in the corner. i tried doing this on my own working note 10 plus with the external keyboard, but i see it scrolls through every notification, so unless you know the number of notifications, hitting the gear is just pure luck.
I have also tried hooking up a usb-c to hdmi dongle (which works and starts dex on my n10+) but it says no signal on the A80, so external monitor seems out of the question.
Is there a consistent way to enter settings, or any way to enable the following settings:
* enable voice assistant (accessibility settings so i can hear where i am and navigate using voice/sound)
* enable USB MTP (or similar so i atleast can access files from a computer)
* enable USB debugging (to use ADB to screenmirror and/or etc)
* alternatively clear notifications so entering settings should become consistant with number of keypresses
I have tried some apps like dr fone but it doesnt support backup from this model, and any other settings wants to wipe the phone.
I have tried holding both volume buttons to enable google voice assist, but also unsure if this ever worked
The phone is not on wifi and i am not 100% sure if wifi is enabled at the moment, nor if it has the current wifi password my friend uses, but i can try do do things from there if internet access will help.
I dont think google now nor bixby (if this phone has that) is enabled as i dont get any reply or voice ding while pressing the win key (home button normally on working android)
I think i can enter recovery and download modes, i got COM5 on odin, but I'm unsure if i ever get into recovery menu.. but even then, is there any custom recovery firmware that will enable usb mtp access at all for this device?
Also, I'm not able to have a computer connected at the same time as a keyboard as I'm using a wired keyboard with OTG adapter.
Tl;dr:
Have:
* A80 with broken unresponsive screen.
* Have access blindly through otg keyboard
Need:
* Need to enable mtp and/or usb debug (alt. Voice assist)
* Need consistent way to access settings
Both MUST be done using only wired otg keyboard.
Tried:
* Hdmi out (no signal)
* computer recovery software (no dice)
* having computer and keyboard connected simultaneously (keyboard works, pc doesnt recognize, could be dongle)
Hope someone can help me (us) fast.

have you been able to verify that the MTP device actually works with other phones?

USB MTP is just file tranfer?
F.ex. if i use smartswitch on pc, it first tells me to unlock the phone, if i unlock the phone with the otg keyboard and reconnect it it says i cannot tranfer files because MTP is not enabled in settings.

sorry man, i meant MHL adapter.
As far as i found out, A8 does not support MHL/HDMI out..
guess ill spend the weekend to try to get voice assist working by blind trail and error :/
If anyone could provide screenshots of the settings menu and/or recovery menu (and if its possible to enter without touching the screen, and if so how) that would be greatly appreciated.
The phone should be mostly completely stock set up, but home icons might have moved and menu icons might not be in the same place, but i think the pull down menu should be the same as any stock setup, so a screenshot of that would be nice too
Hi
As far as Android goes, by unlocking the phone and plugging it into a computer then you should be able to view the files on the phone from the PC like any USB drive. What you can also do is use Samsung Smart Switch and do a backup of the phone on a PC as this will be able to pull all text messages, photos, etc into a backup folder. Then you can restore any part of that backup on another Samsung phone, including messages.
There may be a few things that will not transfer over. As far as viewing the photos and other files, you can navigate to the backup folder on the PC and check everything there. This is all provided that the phone actually works and is unlocked.

As stated in my original post, usb-MTP (file transfer) is not enabled by default, and my friend never connected the phone to a computer, so i have to enable it to be able to access anything.
The phone connects and seems to work fine except the display, smart switch says to enable mtp pn the phone to transfer files after i unlock it, so my problem is activating talkback so i have aural navigation help so i can turn on usb/mtp for file transfer(and hopefully adb) or to turn on usb directly, but i think talckback is the highest priority as it will help me navigate the phone and be sure of where i am, an accidental keypress on can ruin a long sequence and i would have to start again from scratch as i cannot know if im in the same location.
Hi.
Any update on this? I have exactly the same problem and no solution so far...
Thanks
I'm trying to install a clock face I made for the Versa 3 onto my Versa 4. On the watch you need to connect the charge cable (to the pc I assume). Then in watch settings there is a place to enable Developer Bridge/USB Debugging which I assume is how one installs an app for testing. This was via WIFI on the Versa 3. No WIFI on Versa 4. On the screen that reads "To connect to developer bridge, enable USB debugging" I select the switch to enable but selecting the "Yes" button just turns off the screen. It does not restart, and Fitbit Studio does not recognize the watch.
The same Yes/No dialog works for Factory Reset and Shutdown so I'm guessing the switch is just not hooked up correctly in the OS.
I've factory reset a couple of times, once connected via the PC app and not phone app. In that scenario the "Settings" button was greyed out so I couldn't even get to the step I am describing.
Is there some step I am missing? Is anyone else able to get USB debugging to work on this device?
I had understood that there was no SDK for the Versa 4, nor third party app, and that "non Fitbit" watchfaces were watchfaces from Versa 3 ported by Fitbit, not it's original developper... I'd love to be wrong, though.
