This happened previously on my mate 10 pro, exactly as described. I concluded later on that the usb port was faulty and needed replacing. A cheap adapter from AliExpress caused the fault

Its cool. I'm testing same setup have u had any problems with auto connect bluetooth?
Not problem. . But I need push a sony radio for connection bluetooth App remote. .
I have call a Sony for this .. but need manual input..
Any one interested in this check out proclips (Google them). A non invasive easy way to install a tablet in the car. Works great with the Ford Sync system but anything with Bluetooth would be good. I've had iPad's, Note tabs, and now the 8.4 in my Fusion.
8.4 in my Jeep
Here's my setup in my Jeep. I got a custom mount that sits over the stock stereo. It slides in an out and locks. When I want it more secure, I slide it out and I have a lock box below my seat.
I ordered a ground loop adaptor to fix the hum when it's being charged and plugged into AUX. I'm currently shopping for a DAC that I can connect to a charge enabled OTG cable. The best I've seen is LAVA SimulCharge USB 1 but I wish it had more ports. Anyone find anything better?

I have the lava adapter works pretty good. U can buy a 1 male to 3 female USB adapter for more ports. Make sure u have a good 2.1 amp charger and cable for the lava or it won't charge to good. I use a official Samsung car charger and the USB cable that came with the tab pro gets about 1000ma with my DAC hooked up. I use the Behringer uac 202 USB dac best for the money. Has optical also.. No ground loops or noise with optical.

Thanks. I was hoping I could get a 1/3 USB adaptor for more ports, but I didnt know if it would work. I have a two different 2.1 amp chargers now, and it barely gives any juice to it. It says max 1200 or so but it bare;y gets 3-400. It keeps the screen on and it drops a % every 5-10 min. I looked at the Behringer uac 202 but I'm connecting to a stock deck that goes have RGA inputs so I'm going in through an AUX jack. I could try an optical to headphone cable I suppose.
The ground loop cable I got killed the hissing noise. Is the UAC 202 a noticeable difference worth the extra cost and time setting it up? I'm concerned it will slow down charging even more. Does it suck up a lot of juice?
The sound difference is huge with the 202 dac even if u use the headphone out jack. Alot more clarity and output. doesn't suck much juice at all. U should invest in a Samsung Branded car charger most chargers say 2.1 amps but put out half.
Thanks, I just purchased the 202 and the lava so I'll be able to test this out this weekend.
I couldnt find the general samsung car charger that didn't have a cord already attached though.
Now I just need to find a USB backup camera solution and my car setup will finally be complete.

Goodluck. The 3 port one looks pretty large. Does that function differently than if we were to buy a 1 to 3 USB adaptor?
I have my 1 port working correctly. Strangely whenever I use the Lava adaptor it lists it as 100% charges right away, but if I unplug the charger it drops back down to whatever it really is. Not a huge deal, but annoying to not see the accurate battery level when plugged in.
The 3 port adapter is supposed to be better with charging and has a button for charge only wich is cool. And according to lava there is no power feedback from the tablet to the the adapter. The tablet port keeps my usb dac on even when I unplug power With the one port. And I'm sure that the 3 port will have no problem with a dac hard drive and mouse (hopefully will let everyone know when I get it in a week or so).the one port would have a power supply issue with all 3 devices.

MHL to HDMI on an S3 with broken screen/Digitizer... how to make it work.

Hello,
I have an i9300 running a famous Custom OS : OmegaROM.
My digitizer/screen is broken : I can not see a thing on the screen.
I got myself this cable : http://www.morhipo.com/pl-8098-2-0-usb-to-hdmi-kablo-seti/17073032/detay which is supposed to be working on a S3 (written on the box).
However, I never did that before and I can not see anything on my computer screen with the HDMI on.
I hear the sound of the phone when i press the volume buttons, and thats all, so the phone is on...
How do I make this thing work?
Should this thing work in TRWP mode (think not) and how to make it work without access to the screen.
Is there a custom ROM that would have MHL running buy default?
Thanks for your tips

hey man sorry i can't really help but i have to ask you this: the mhl cable usually has a hdmi port which connects to a tv/monitor ( you can't connect it to a laptop with a hdmi port), and 2 microusb jacks: one that connects to your phone (the male one) and one that connects to the charger (female jack). Did you set those up correctly?
Also, have you ever had your microusb plug replaced on the motherboard? It is possible that sb replaced it with a 5-pin jack whereas the s3 has a 11-pin mirousb port.

OTG

On my Le Max2 OTG does not work .... and in your?
How can I fix the problem?
I didn't have a device to try that, but I tried connecting a gamepad via bluetooth and tried to listen my music via bluetooth (Car-Media-Device was the output). Neither of them worked.
Bluetooth working fine on 14S ROM. A little slow to connect but I have connected 4 items and all work fine @massymoroboshi OTG is also very good, I think its fast too.
I have used USB type c drive and it just asks to allow
For computer make sure 1 drivers are installed an 2 select media device from dialogue box the phone opens when you connect
ok thanks .. I have tried with an adapter micro-USB / USB-type-C + OTG cable, and is not detected by the phone. The PC connection is ok, I'll try to buy an original OTG cable

Im on 14s right now. Still USB otg not working. What am i doing wrong
Hi there!
I Think I've got full information on the OTG matter now after googling and testing stuff.
tldr; Get a USB (3.0?) Type C OTG Adapter, it will work.
Longer version:
After getting my USB C to micro usb adapter I tried getting my USB Sticks to work, no luck, not even blinking so I guess not even power get to those things like this. Then I started googling to find out that the same issues were already persistent with older LeTv phones.
Then I went out to buy a USB C 3.0 OTG Adapter (cost me ~7 bucks in Saturn in Germany, will be cheaper to have online for sure), got my sticks to work and even my 2,5" External HDD without any hiccups. ROM I'm on is 14S, not on the newest update.
I will attach a pic of my adapter so at least you know of one that is confirmed to work.

Jeah I also got it working. Bought a type c Adapter on Amazon for 3€. Pretty stable for stick and 2,5"drive (drives first startup is Pretty long, about a minute) . But there is currently no support for game Controllers via otg neither via Bluetooth
Successfully connected and paired the PS4-Controller via SixaxisPairTool on my Le Max 2. Now I can finally play games without a problem with my PS4-Pad

Headphones and charger splitter

I've read that some of the usb type C to 3.5 jack adapter are working now with a proper DAC, but I can't find a splitter that works for our HTC's or even for Pixel 2. People mention dongles made by certain companies, but I head to their websites and there's nothing available...
Can anyone help me find a viable splitter to charge and use headphones at the same time? I'm getting desperate, to be honest...
Thanks!
I have also tried several usb type c hubs but could not find one that works with htc headphones unfortunately.
I ended up buying an Bluetooth receiver to plug my headphones into when I need to charge too.
Not ideal but it works for me

Hey, that doesn't sound bad to me. I've never tried anything like that, though. Could you send me a link to your receiver or tell me any reference to start searching? Thanks in advance!

HIFI Bluetooth 4.1 Audio Transmitter & Receiver, Lenuo 2 in1 Wireless Music Adapter for TV / Home Stereo System Headphones Speakers MP3 / MP4 iPhone and More https://www.amazon.co.uk/dp/B06XRM8GXD/ref=cm_sw_r_other_apa_2ePXAbY8J5FFD
Look for a Bluetooth Receiver that supports wired headphones, i.e. it has a 3.5mm audio out socket.

Checking that out as we speak. Thanks mate!
Hi guys,
still trying to figure this out. I hope you can help me with this idea. All I want is charge and use headphones at the same time :
If I plug this hub (or similar one) to my U Ultra's usb port https://m.es.aliexpress.com/item/32846535696.html?trace=wwwdetail2mobilesitedetail&productId=32846535696&productSubject=USB-C-Hub-USB-C-HDMI-Ethernet-Adapter-for-Macbook-Pro-Thunderbolt-3-Type-C-Hub
And then use this adapter (with DAC integrated) into the usb c of the hub: https://m.es.aliexpress.com/item/32832480232.html.
Will it work? Or the DAC needs to be placed exactly in the usb out of the phone? I'd really appreciate the help.
For these hubs to provide charging you need to connect the charger in the type c port of the hub which is marked with the lightning sign. To connect the 3.5 mm adapter you will need another adapter from usb type a male to type c female. Such adapters exsist but when i tried to connect the htc type c headphones via the hub and such adapter they were simply not detected by the phone so i doubt that the 3.5mm adapter will also work in such configuration.

If I decided to go for Bluetooth earphones... Any will do, am I right? No DAC thing to be worried about, I guess...

That's it, exactly. Take any BT headset you like and can afford, they have the DAC already built in.

USB Port is broken. Charging does not mean your port works flawless. You will not get sound over usb-c dongle until you sent it for repair. The pins inside usb-c were used by different mode like audio/video/data/power.
The Pins that were used when charging were working, so you have fast charge, but some of the pins used in audio mod were obviously broken. That is why you have no sound.
They tried to make it out that is way my fault due to water damage.
Until I pointed out that the phone was water proof ?
My nephew's M10P (that I gave him to get my M20X) just did the same thing. Charging works fine and speakers on phone are fine. Was hoping an update bug.
Update: i bought a new headphones and it work fine... My oldest headphones was just damaged
