I really wonder too

dont't think you can.

Why?
May it runs with CM7, or not?
Hasn't anyone the drivers?

I started a thread some time ago about OTG issues on LGP990, AFAIK, OTG needs kernel support, and some tweak settings (software/drivers) to get working, there doesn't seems to be much dev momentum on OTG support in CM (also did feature request like a year ago on CM N1 port, the request thread was dead)
The great hacker Benee (vorkKernel-OC/UV Kernel) did mention he might have a look on OTG support, but this sure is not his current first on the list (understand and agree, and thanks Benee there! nice kernel)
I personally will be giving up the LGP990 real soon since POOR phone Q, and going for SGS2, which has the noise cancelling on calls, and the USB OTG support by default......if you are looking for OTG that seems to be the fastest way to get them....
just my 2 cents.

Sorry Tomg58, nope, I am not, Kiwi I am....
Anyway, I think I will be missing the thread, I am going SGS2 tonight and P990 will be away tomorrow for good.....

SGS 2 is too much for me.
I am a pupil and 13.
And I will buy a EEE PAD Transformer.

so last post was made more than year ago, maybe we have some good news about OTG support?

otg on optimus 2x is not possible. not enough voltage supply to the micro usb port. unless ofc u will use external power source, but thats bullcrap if you ask me, not worth it.

I've found this source code for some tegra otg... I hope it can help with OTG development for P990. I'm new to this forum, this is my first post here. BTW, I don't see any problem with external powering... when I'm on the go, I can always use usb Y cable and power it with my 5V cigarette lighter usb adapter on 12v car socket.

I'm sure p990 hardware is capable of OTG, we just need someone to enable it in the kernel, maybe just some #define stuff, and we need a rom to support it...
Maybe pengus77

What means OTG?

Basicaly it means that you can conect usb stuff to your p990 with a special cable

Battery discharges even if it's charging

Hi. Firstly sorry for my bad English, I'm Spanish and I don't speak it very well. I've THIS [ **[ROM][CM10.1][4.2.1] Asylum CM10.1 Nightlies - Slim, Fast and Smooth 4.2.1 Rome™**]ROM, but I've had other ROMs before.
The problem is that when I'm using my phone, the battery discharges even if I'm charging it. I've tried with some chargers with the same result.
Thanks for your time.

Try cleaning the usb port with alcohol. It might be faulty and need replacing its a common issue on the notes I suffered it last month

Go to system settings > Developer Settings and enable Show CPU usage.
Look whats taking up your CPUs time (that process should be at or near the top) and try to get rid of it.

I haven't got that option in this ROM (or I don't find it...)

Best thing to do now is reflash stock firmware and claim for usb module to be replaced if you have warranty ?
You can buy the part with instructions to do it yourself but if you have warranty dont take the risk, let the pro's fix it.
if you cant connect to computer to flash firmware, download mobile odin and use that, download the firmware files either from your phone or pc (which ever had fastest connection) and flash them with mobile odin.

Firstly, thx for your answer.
The USB port works fine, the problem is that when I am using it, battery discharges...
Is the part expensive? I'm out of warranty.
Regards.

Before you go about changing the usb module and all, try a different battery too.

Just 2 quick questions: where do you charge your phone? On the wall plug, not the PC's USB port, right? Is your charger the stock one (by Samsung)?

Exactly, but there's a curious thing: I think (not sure) that when I charge it in the PC's USB port it works fine... but not on the wall plug.
Yes, it's, but I've tried with other chargers too.
Thanks for ur answer

Safety of chargers

As long as I'm using a good A to C cable (approved by Bensen), is there any harm in using an old AC brick like from an old Motorola phone? Only outputs like .2a so I get charges slow. Just want to make sure no safety or damage issue

0.2A? That would take forever to charge. But yes, should be fine if it meets specifications.

Dash Charging works in OP2 as well

This is for those who have previous generation of OnePlus phones. Dash charging seems to work flawlessly with OP2. My colleague in office took my charger to try out and we were both surprised when his OP2 didnt blew or got hot . Yet to test it out with a OP1 as i dont have any. Would be nice if someone can test and let others know.

But it doesn't charge as quick, right?
Of course it'll work, it'll work on any other phone, just behaves like a regular charger.
Tap-a-talked from my Nexus 7

ofc the charger works but probably not with the full 4 or 3.5 Amps as it does with the OnePlus 3

Dude, I've charged my, Anker power banks, my Vita, my PSP, my OnePlus One, my Bluetooth game pad, my LG G watch, and my 2DS. The DASH wall wart still behaves like any regular USB wall wart. Seems like it charges them at the standard 2.4amps

Please post a charging screenshot. I am sceptical of this claim.

Not true!
There is a YouTube guy who tried it, you can see in his video that his OP2 charges, but not 60% in 30 minutes. But the charger is compatible, but not as fast as OP3 (which has Dash support ofc)
Sent from my ONEPLUS A3003 using XDA-Developers mobile app

If works mean charging, it surely will, just like QC charger works on non-QC devices.
But the thing is OP2 has no support on neither QC 2.0 or VOOC(from OPPO, or DASH, which Oneplus names it), while the latter brings the advantage by extra pins.
So OP2 does not support QC in whatever protocol.

Stop this thread it's nonsense and a waste of time.

Agreed

This should be closed. Soon

Is DeX charing your note 8 as fast as standalone AFC brick?

I have noticed that when i add only the charge to DeX (the one from Note8 box) and the original cable, it does not say "Fast Charging".
Is it yours the same?

Dex does not support fast charging which is a shame

It can't because of how Quick charge works. Passing data through the data cables because you can't push data and power through the same lines. That's why PD is a better option(See Nexus 5X-Newer and Pixel). Of course marketing will always win.

So will the phone die if you're using Dex all day or does it give you enough of a charge to keep it topped up?

I think it should at least give 1.5A charging like most standard chargers do. Don't quote me though best to ask Samsung. I just know the way QC works it uses data lines for charging to get faster charging so it can't do both.

The phone uses QC. By that alone Android O isn't going to do a thing. One of the requirements for PD is no modifications to the VBUS which Quick Charge needs in order to work.
