Hi, Where is the Quick Charge Settings - turn on/off? Thanks
There is no QC setting. If you dont want to use QC just change the charger to one that does not support QC.

I am sure there was a setting in SETTING, ABOUT PHONE, COMMON, BATTERY but I cant find it now after updating to the latest update.
I've never seen any setting, in any menu - hidden or not, that allows for the end user to enable or disable the Quick Charge aspect of any smartphone that I've ever used (hundreds of 'em). The solution, as already presented, is to use a traditional USB charger that has no Quick Charge support at all, or attach your device to a traditional USB 2.0 or 3.0 port which obviously limits the charge rate to the USB spec per the given port.

I've never seen that. I do have a bunch of screenshots of various settings over the past couple of years. I'll look through them to see if any are of the battery section, to try to settle this one way or the other.
You can also revert to past firmware very easily to check yourself...
I've never seen a "COMMON" menu entry so, that's what immediately told me there's something funky going on 'cause, that's just not something you'll find in any stock ROMs I've ever used on any device.
And since the UX changes from back on the G4, the menu items are Settings - System - About phone - Battery but all you find there is the battery status and battery level.
So I have n clue what that poster is referring to unless it something in a custom ROM, and even with Lineage and others I've never seen such an entry.
Could be a fluke, or just a mistake, who knows.

Hi Guys,
First post here so I could'nt post in the relevent thread. It has been noticed that there is a switch on the Tablet S PCB that apparently disconnects the battery, I've opened up many devices over the years and have never seen that before - very strange if you ask me. Might be of interest to some to note that the Sony PSP used an anti hacking method that utilised the battery !!, so we may be on to something here.
On PSP a hacked battery is called "pandora battery". It is not a switch. The battery has four contacts. Two of them are the voltage contacts plus and minus and two of them send a serial signal code. With the right code, the PSP boot in a special (hidden) recovery menu. Do you have more information about the tablet battery and the switch? Pictures available?
Wouldn't the relevant thread be the ones you found out about on it?
original discovery of switch here (with pictures)
Then I brought it up in the dev thread about APX mode here
And yes it exists... can confirm it's there (at least on my 16gb model anyway)
My thoughts are is that there would be a factory cable used here (similar to the motorola factory cable) and they need to disconnect the battery for it to function as it should.
And a hunch that it could very well have something to do with APX mode, however... since people have stumbled into APX mode completely by accident with no hardware commands, that kind of contradicts that thought.
I don't have any info on the battery or the switch, I was just pointing out the strangeness of having a switch to disconnect the battery, nothing else I have ever looked at has this feature. (and I've opened up a lot of devices)
It just makes me think that there is a need to easily and repeatedly disconnect the battery during the manufacturing / assembly / repair process.
For example, does the system "know" when the battery has been disconnected and allow different operations ? - fastboot perhaps ?
I know this is all supposition and it may mean nothing at all - but the feature is bugging me - it cost money to implement and I can't help but feel it's there for a reason.
System woiuld'nt let me reply in thread I was reading - said dev section was for expert users only ??

I thought of this too but then went on to think that there's probably no way such a thing would transfer accross do android/unix codes like that. ie they use android kernels and stuff, they don't make the whole thing themselves. Plus they realised the vulnerability of it and removed it in models like the psp 3000 and go (not sure about 2000).

Early PSP-2000 models still had the vulnerability.

You're actually pretty close, I think. Android would be perfectly capable of receiving certain boot codes, but these are far more likely to be wired to the more capable micro-USB port as in just about every other Android device. While an Android kernel could theoretically receive serial codes from almost anywhere given the right instructions, Sony would probably not do this. As mentioned, the PSP's ability in this regard caused many problems.
As mentioned by the others, if someone could post some good hi-res shots of the battery and surrounding PCB or something like that, that would make it much easier.
Sony's philosophy has always been that the end user should use the product as it was built and the purpose it was built for.
They've always made hacking and rooting very difficult for users. They don't like their products being tampered with.
I can understand where they are coming from, but at the end of the day, with many phones and tablets, if root techniques and mods aren't available, many users won't buy the goods.
All PSP models, including the 3000 series, excluding the go have been cracked.

pandora battery worked for psp 1000 and psp 2000 before the TA-088 V3 motherboard, all the next models where hacked by firmware homebrew enabler, but not by battery mod..

Just to clear things up, what works on the PSP will not, generally speaking, work on the Tablet S. They are different hardware, with different interfaces to different firmware which runs completely different software.
If we can get a look at the PCB in closer detail where the battery connects we might be able to see if there are any serial pins, but I doubt there will be. No other Sony product since has featured it (to my knowledge).
Any chance of this being supported? I did plug my USB OTG stick into my cradle but nothing happened... I know, wishful thinking lol...

The USB OTG spec uses the 5th pin on micro b, which is not exposed via the cradle. Early devices and those not fully implementing the spec in hardware and software where able to use helper software to force the port into usb host mode which may be worth a try, however a quick search only yielded android otg helper tools which depended on the hardware.
Most of my experience with these older devices where non-android except for the old G1, so a bit of research would be needed before seeing if a software-only solution can be implemented. Barring that, I'd guess a hardware modification would be required to expose, toggle, or force the missing pin.

Urgh that's annoying and all because they missed off just one extra pin, anyway thx for getting back to me with such a detailed response
I want to be able to plug my new Galaxy Tab S3 (T-820) into my desktop computer or laptop via the USB C cable and not just move files back and forth, (which works fine), but ALSO have access to my desktop's internet connection through USB. I don't want to use WiFi.
I have an Ethernet to USB C dongle, which works fine, but it doesn't allow me to share files or charge my tablet. I'd like to be able to do all three at the same time.
In many of the "How To" articles out there where "Reverse Tethering" is described, they helpfully list the various buttons and widgets to click in order to enable this feature. However the authors always refer to menu items and buttons which don't appear under my tablet's settings. They're not just greyed out. They're simply absent. So that doesn't work.
Neither do any of the various apps on the Google Play Store and elsewhere which promise to provide reverse tethering. They just don't work.
SO...
Being new to the Android (and the smartphone) universe, I did a ton of homework and have so far figured out how to...
Root my tablet. (Done!)
Wade through the swamp of TWRP, ODIN, etc., while tripping spectacularly over the various speed bumps and permission walls provided by the likes of Samsung and Google's paranoid anti-theft (and it would seem from my use case, their anti-happiness) feature set.
Successfully install different flavors of Android.
Install both Magisk and Xposed and try their tethering unlockers with negative results.
After a week of little sleep, I've managed to get through all of this torturous nonsense and amaze myself by not having bricked or totally spoiled my tablet. It still functions! After all the warranty-voiding BS I've crammed through it, I'm feeling quite lucky.
However... I still don't have the ability to tether/reverse tether!
I've learned a lot, but I still feel mostly like a dazed and confused script kiddie (remember when 'script kiddie' was a term? Well for me, it still applies nicely.) I'm trying my level best, but various elements of this whole exercise remain opaque. This is my first post in any forum asking for advice because I finally hit the outer bounds of my DIY energies and pride.
So, if you will indulge my humble request, what I want to know is...
1. Is my tablet even capable on a hardware level of performing a reverse tether, or has the manufacturer locked that feature out so that even a ROM which promises to turn it on will fail to do so?
AND...
2. If it IS possible for a ROM to turn on the tether/reverse tether feature, which one is it and where can I find it?
2a. If there is another solution.., what is it?
I'm currently on...
Android Version 8.0.0
Samsung Experience version 9.0
Kernel Version 3.18.71-13482624
Build Number R16NW.T820XXU1BRE2
I bought this unit off Amazon; it was a refurb and I didn't get it through some cellular provider nor do I have a phone plan. I don't know where this tablet originally came from, but it was all new, sealed and shiny in the box when I got it.
Thanks!
I can appreciate losing a week of sleep. But I don't understand why you need to reverse tether. Enable WiFi and there you go. I think the last time I needed to tether a device through my laptop's internet connection would have been the 1990s.
FWIW the USB-C connector on the TAB S3 is different because if you want to drive an HDMI monitor you need a DisplayLink chip enabled dongle and DisplayLink Presenter app running on the Tab S3. Whereas on my TAB S4 I can just plug any regular old USB-C -> HDMI dongle and display on the monitor. So odds are trying to get reverse tethering working on the Tab S3 is going to be an exercise in futility.
Hi there, you still looking for reverse tethering for android? i found & use this for a while... you can check github link here : https://github.com/Genymobile/gnirehtet
working well on my S3.
Holy cow, it works!

What...? It worked?! Thank-you!
It's hard to believe how much effort and research I'd put into this, how many promising fixes I tried and which failed. In truth I'd given up weeks ago and found myself scornfully looking at the expensive tablet by my desk, wondering if I should hang on to it for its limited uses or sell it on eBay.
Thanks for posting! I can now do what I wanted with this machine.
For others, just follow the directions on the github link provided in the previous post.
I just scrolling around to find fixes for wifi issue - it connect & reconnect every times when on my office connection. Since me unable to use wifi, i try to find the work around using LAN connection. Then i found that.
Happy i can help others. Cheers mate.
Been looking at the Facebook Portal, it's got a USB-C port on the back but according to Facebook's support it's only used "in the factory", so I'm assuming maybe that's something they might use with a flashing tool to reset damaged units. Has anyone messed around with one/found out anything about how it might work? I've noticed that, at least with mine, if I hold down power and the volume up button while it's booting, the screen remains black but the mic light is still on. Thinking this may be some kind of recovery mode perhaps.
Wow, you bought one? I can't imagine.

Oh definitely not. Wouldn't be caught dead buying one. XD Was gifted one as an early christmas gift by a friend, but trying to decide if it's something I can do anything with before I maybe... return it and get a better alexa-enabled device. Feeling really bad about that though considering they wanted to use it to communicate.
Ah-ha! Alexa enabled, but what powers it? Is it some open source thing? AOSP even?

From what I’ve been able to gather, it’s running on some form of AOSP with a custom Portal skin- haven’t been able to get much more info than that though as the info on the device past what FB has put out publicly is pretty slim. Definitely doesn’t surprise me that it’s an android device though considering that’s just about all FB seems to develop for outside of the web (Oculus Go, Facebook Home, etc.)
Would be really interesting to try using Discord on this device though, and possibly finding a way to disable FB functions. Might make it a good gift then, if not it’s making it really hard to hold onto it.
Edit: This is my source for AOSP, assuming it’s the “Android Open Source Framework” mentioned:
https://techcrunch.com/2018/10/08/facebook-portal/amp/
I got my hands on one (free gift from company) but I'm trying to figure out what to do with it too.
Hello everyone, sorry I am late to the party. It is definitely android. If you run the chromium browser and attempt to open something like a pdf file, chromium will give you an error and ask for download permissions. This error message also gives you a link to the applications settings page from where you get access to some of the settings. No permissions sadly. You can however go in to the battery optimization settings and filter for all apps and get a full list of everything installed. As can be seen in these images on imgur /a/QWqs0pP
Portal USB-C is video out!

We're stoked. We've been using the 15 inch Portal in our conference room. Hooked up a usb-c to HDMI adapter, ran it to our conference room 4K television and bam! Absolutely gorgeous.
Works flawlessly as an output, and even audio (as would be expected) is now running through the monitor.
Oh niiiice ! I actually asked facebook portal customer support, and they said nothin could be done with the usb c port ! It really is a shame cuz some people probably want to output to a bigger screen !
I want to try if usb c headphones and microphones will work. I don't have any around though !
I've tested and seen that I can use the port as a usb c PD charger, it charges my macbook pro and oneplus 6
Maybe we can figure out a way to use ADB to get us into the portal ?
---------- Post added at 05:26 PM ---------- Previous post was at 04:51 PM ----------
Oh wait, never mind charging my macbook pro. It does so only intermittently, I should've guessed the power was too low !
So, any luck unlocking the bootloader or even getting ADB out the USB-C ?

USB-C to 3.5 mm audio only alternate mode?
Can anyone please test and let me know if a USB-C to 3.5mm analog audio jack also works - for 3.5 mm jack headphones or speaker out? More specifically, an active adapter because a passive one may not work. Such as this one: amazon.com/Tranesca-Headphone-Adapter-Compatible-Google/dp/B07M6Z2KJ4
What I do know from reading this thread is the Facebook Portal's:
- USB-C Video out (DisplayPort Alternate mode) to monitor works along with audio (monitor passthrough)
- It works as a USB-C power delivery charger
But if audio thru DisplayPort works means only audio to 3.5 mm jack will also work?
Interestingly, the official documentation (portalfb.me/2NAdtz1) claims the audio will continue to come from Portal's speakers. But people here claim it is transmitted to the monitor?
the portal burnt due to an electricity hazard overseas.
I just bought the newest Facebook Portal Mini. it comes with a browsers from Facebook. I was able to make a phone call using duo.google.com then the next day.. I lost permission to the camera: it keeps asking me for permissions.
I think they have some kind of firewall that blocks unusual behaviors

I don't really know how to do those things... But it tried scanning my portal for open ports, no ip adp connection possible. And then, with usb c connected nothing happens with adb. It can't seem to see it !
I tried enabling hidden developpers options by pressing a lot everywhere in the settings, but no luck !
Alrighty, I've got an update for you guys. It seems like FB locked out that PDF trick sadly. However, I found out that if you restart your portal and hold all three buttons down, then plug in the USB-C, it appears as a device named "Qualcomm HS-USB QDLoader 9008 (COM3)". Based on what I've seen on a few threads here, that's a utility for reflashing and backing up device firmware. I believe we may be able to do stuff with this.
I am looking into getting the FB Portal TV. If the party on the other end of the connection is using their smart phone or tablet, does the image I am seeing become altered from wide screen to a vertical image
or does the unit adapt to keep the screen filled without becoming distorted in some way?

Have you been able to find out anything more with the qualcomm loader? I have been playing with mine and unable to get a utility to recognize is. It would be nice to be able to get get the fw off it.

I have not made any progress at all. I keep checking to see if anyone has done anything at all, but I think these devices are not too popular. Hard to find any information on them at all
So I was able to get fasboot access to my Facebook Portal+ (1st Gen).
If you plug in the power and hold down the vol down + power button. It will show the portal logo on the screen and on a black box it says "Please Reboot...". If you connect to the usb-c port then it looks like there is fastboot access to the device. It's definitely locked down, but it's a start.
I've been trying to figure out how to get adb / sideload access for a while now and this is as close as I've been able to get. I'll let you know if I find out more.

Hey guys,
The Mi PAD 4 is the perfect size(in most cases) for a car dash mounting and will be a great replacement for the now very old Nexus 7.
There have been a lot of development over the years of custom ROMs/Kernels that are specifically optimized for such a use scenario.
I for instance am in the process of collecting the needed cable and accessories but since my ROM building knowledge is very limited at best, would be very happy if there are more people here that think this idea is good and somebody builds us the custom ROM/kernel for that.
So lets discuss this.
What we will need are the following main things:
1. Kernel/ROM that is configured for a landscape use.
2. An option to have the device connected to power all the time but not charging (not to kill the battery)
3. An option to turn on the screen automatically on getting power over the USB port and turning of the device after the power is gone (car turned off) (preferably with a delay of some sort)
4. After power is lost to put the tablet in very low power mode by disabling WiFi/LTE/Bluetooth and so on (again configurable) This is to avoid draining the car battery if left for a long time parked.
5. Simultaneous Charging/OTG (this may actually already be possible, but I have still not found an OTG HUB that works properly with the Mi Pad 4)
probably I have forgotten some more things...
Have in mind that all of those I've mentioned above, already have been developed in one form or another for the Nexus 7, so it should be easier than starting from scratch...
Hey,
i am using my MiPad 4 also in my car. So far it is working fine.
I have connected the MiPad via USB to a carhifi DSP (in my case Helix MiniDSP)
Here are my answers to your points:
1. i am using Evie Launcher in landscape mode.
2. see 5.
3. MiPad is waking up and starts to play music as it detects the DSP on the USB-Port when the car is turned on, and is stopping and turning off when the engine is turned off, this is working with the Pad itself and the app Automate
4. use app Automate to turn off all radios when no USB connection is detected
5. i am not sure if this is related to the hardware of the MiPad or the Kernel, i have tested some CustomRoms but was not able to get it working, so i switched back to preinstalled inofficial international MIUI-Rom
Thanks
Hehe i also use it in the Car It was also a Replacement for my old Nexus 7 2013.

Can you please throw some more light on the "preinstalled inofficial international MIUI-Rom" ROM where simultaneous OTG+Charging is working for you? Is this is the fake ROM (as people call it) that vendors install after unlocking the bootloader and then sell it to you?
May be a link to the ROM (if its downloadable) or a screenshot of the ROM information from the tablet, will help.
TIA.

HavocOs is working great so far in my car setup.
Which havoc os rom are you using? I flashed the current build today and otg plus charge doesn't work. It's one or the other.
I will next month also run a project for building in my mind in the cars radio mount (2din). So far I found Headunit Reloaded is really cool to have Android car working perfectly! For volume control I use a floating volume button (Virtual Volume Button on Play store).
But the rest I will figure out next month when I get my car finally haha
