access USB diagnostic mode seems deactivated... - Samsung Galaxy Z Fold 2 Questions & Answers

Does anyone can access the USB diagnostic function with *#0808# ?
It works perfectly fine on any other Exynos or Snapdragon phone from Samsung, even on the S20 Ultra - but the Fold 2 seems out of luck... someone any idea?
Best regards from Germany!

[Help Thread] How to Make Ethernet Adapter to Work With S7

I have Samsung Galaxy S7 model SM-G930FD dual sim for asia pacific region. I want to connect my phone to internet using ethernet to usb adapter connected to OTG cable. I read somewhere that this is possible to do in android since marshmallow, and there is many people doing the same with other phone and it works. But I can't make it to work with my S7, anyone knows what I should do to enable it?
Maybe give this a try (if you're rooted or willing to root)
I'm not sure if this will work on Marshmallow or even on the S7.
Contact the OP of the linked thread and see what they say.

Yeah I got a otg usb Ethernet. Works with my nexus 7 though not with my s7. Samsung cutting corners again with their software? Tried a couple of root apps though they don't work either. Any ideas?

Galaxy S7 OTG problem

I recently obtained a GS7, when I hooked up a working usb device, it does not recognize that anything is there. I installed a couple OTG detect and repair apps, and they reported everything should be fine. Phone is equipped with OTG firmware. The usb device works on several other phones, but this phone cannot detect it.
Any ideas?

It's better than the more expensive Note 10 phones because it has a 3.5mm headphone jack and a non-curved screen. It's also far less expensive.
It's better than most other phones because it has the S-Pen (which I personally consider to be super useful on on my Note 8).
All in all, it looks like a great phone that offers the best combination of features for the price, especially to those who want a stylus.
So what?
Did I said anything about good or not good? I said it is not DeX compatible.
Btw. I tested this by myself, with my very new Note 10 Lite, coming from a Note 8.

As an owner of the Note 8 who is really impressed by the Note 10 Lite specs/price I'd be very curious to hear more details about this upgrade. What are the biggest advantages and compromises from your point of view?
Front camera sucks.. exchange my note 8 with note 10 lite and it is one of biggest mistake of my life.. performance is definetly better but the feel of curved screen I miss most.. note 9 has much better camera. I suggest to buy note 9 instead of note 10 lite
I am also interested by the Dex feature on this phone. But first as anyone tried to plug this phone a usb c to HDMI on a screen/TV ? I've read somewhere that the USB port does not handle HDMI output....
OK I tried some dongle and there is no HDMI out, like I read here and there on the web (USB-C 2.0 not 3.0).
So I'm wondering if it would be possible to port the new dex that is working over the air.
It is available on Note 20 on the One UI 2.5 update. Any idea ?

No! it doesn't work... it just got the support for USB C HUB's (hubs that have Ethernet, tons of usb ports, memory card readers, usb c power delivery...), but the video output (VGA or HDMI) does not work!!!
I just tried something that might work as DeX... I plugged in the USB C Dock(conected to the hub a wireless keyboard and mouse, ethernet and Power Delivery ) to the Galaxy Note 10 LITE, then I turn on Smart View to broadcast to the TV and I got a experience like DeX on the TV!--- Floating Windows, independent application view, etc---
I'm wondering if the Galaxy Note 10 LITE is not supporting the USB 3.0 just because of lack of the USB 3.0 drivers(ANDROID INTERNAL USB DRIVERS FOR HARDWARE), the Galaxy Note 9 uses the same Exynos 9810 chipset and supports USB 3.0 video output!!!

My guess is, it's not a driver thing but hardware to limit cost. Note 10 lite is not considered as a High End device. That's why we don't get all the good stuff.
I'm gonna try to get my hand on the latest Dex APK and try to decompile and patch it so maybe we can use it on our device wirelessly. But, hey, I'm not an expert so donc expect me to find out any time soon.

I bought the Dodocool 14 in 1 USB C HUB... you can use the ethernet port and works really well, plug a wireless reciever, usb 3.0 or 2.0 and can work together, SD cards too... I haven't try the USB C Data port, all let you know when I test it... and the Power Delivery, I conected the wall charger that came with the Note 10 lite, to the PD port of the HUB and started to charge the phone...
This is the most important feature for a DEVELOPER TO CREATE FOR NOTE 10LITE!
Hardware wise is capable, but SOFTWARE is not permitting this feature. I hope that a DEVELOPER will be so kind to HELP on that!!!
Any app which can be used an alternative for dex?

Tablet with OTG+Charge

Can anyone please help me with searching of tablet which simultaneously can charge and support keyboard+mouse.
I bought a Type-C hub ( https://www.klick.ee/swissten-usb-c-hub-8in1-with-3x-usb-3-0 ) and it works perfectly with my Samsung Galaxy S20, but my Samsung Galaxy Tab A7 (2020) doesn't want to charge with it (keyboard and mouse are working when adapter is not attached).
Any ideas why this happening and what tablet can you advise to me?

Looking at the A7 specs and the S20 specs, you would notice two differences:
The A7 has a USB-C 2.0 port while the hub is a USB 3.0 hub (probably 3.1 or higher). Massive difference in capability. There are other hubs that could work, but those don't support ethernet at the same time.
The S20 supports USB on-The-Go, the A7 doesn't (at least not officially anyway).
Conclusion: Buy any Tablet from a reputable Vendor with a USB 3.0 (preferably 3.1 or higher) and an Official USB OTG certification. The rest is how much you want to pay .

Thanks for an answer!
The thing is that I tried same hub with SM-T510 (specs) and works with this tablet. I also was yesterday at the Samsung shop and vendor tried original HUB and it also didn't work. One guys on reddit told:
"CorgiLover234 I have the exact same problem. I have two QGeeM hubs that both support OTG+Charge on my S20, but neither one supports charge on my Tab A7."
So, seems that it is problem exact of this model...

Note 20 Ultra OTG problem

Hi, I bought an HP x5000m usb with type-C included, but I have a problem, my note 20 ultra does not read it when I try to connect and nothing doesn't show on screen.
I tried the usb on other phones and it works. Also my port is OK.
When I connect this usb and restart the phone it shows the device, but when the phone is On it doesn't show....
My phone is Exynos 256gb..
Also I tried to format from phone but the problem still the same
Any solution?

I know that it's been 2 years. Did you find an answer to this problem by chance?
