Flash this and let me know your outcome. I have yet to have a chance to do it but aside from plugging into a computer it looks to utilize the internal storage and charge from wall as long as D+ and D- are not utilized though a PC.

[Nexus 7 General] littleguy77:
Also you won't be able read the card at the same time you are using a fast charger, since it shorts the data lines together.
[Nexus 7 General] les02jen17:
Subscribed! I'm about to get the Nexus 7 but was hesitant because of the lack of a microsd slot. I saw this and thought, why am I even worried? :D Thanks for your work!
[Nexus 7 General] xboxexpert:
Its going to happen and its going to get cleaner and if possible even easier solutions.
[Nexus 7 General] nst6563:
unless you modify the charger to not short the lines. There was a thread linked in here a few pages back where someone tested a bunch of charging scenarios and the N7 charged the same with or without the pins shorted. Hell I'll try it tonight if I get a chance to get away from work.
[Nexus 7 General] littleguy77:
Sure, it will still charge. Just slower. When the pins are shorted, that tells the nexus that it can pull up to 2 Amps. If they're not shorted, it will only pull 0.5 Amps, as per the USB spec.

Of course you could modify the kernel to change this behavior as well, to keep the fast-charge functionality. But now you need some other mechanism to tell the nexus when it's safe to fast charge. If you don't, you could fry a dedicated slow charger, or your PC will shut down its power on the USB bus, preventing you from charging.

I fear that some people may be oversimplifying the problem, thinking you just need a kernel patch here, or a switch there, or a resistor here, or a step up converter there. All those solutions fix part of the problem but introduce new ones. Sure, you can write a kernel to change the charging behavior, but now you've circumvented the natural safeties built into both the hardware and the software of not just the nexus, but also anything you plug into it. Please see the attachments.

In reality, you need to ensure that solution is safe for ALL of the following:

Nexus

internal card reader

PCs

fast chargers

slow chargers

peripherals connected via OTG adapter

That's no less than 6 different things you need to keep from frying or malfunctioning!

It's not easy and in the past month of researching this heavily I have not found the magic bullet. In my mind, if I were to do this right now, I'd put a quad-throw dual-position switch on the 4 ID / D+ / D- / VBus lines. With the switch in one position, you get stock behavior. Switch in the other position, you can read the internal card, but can't connect to anything external (fast charger, slow charger, pc, gamepad, etc.). Sometimes the best approach is just to KISS.
[Nexus 7 General] gizmomelb:
I read on here today where someone had modded the kernel to allow charging while accessing data over the USB at the same time - I think it was in one of the threads where they were using a nexus for a car computer / audio head unit.
[Nexus 7 General] littleguy77:
Yes, I know all about that. But a kernel can't fix the problem when the data lines are shorted together by the fast charger. That's strictly an electrical issue, nothing software can fix.

After reading these threads for such a long time they're starting to sound like "You have a mouse problem? Simple, just bring in a bunch of cats! You have a cat problem? Simple just bring in a bunch of dogs!!! You have a dog problem? Simple just bring in a bunch of...."
[Nexus 7 General] nst6563:
since this mod isn't exactly for the faint of heart nor beginner, then the ability could be built into the kernel to enable fast charging or not, with the option to be enabled/disabled in the rom/os. Not sure this would be an option either however since it seems that if you enable fast charging, it disables the usb functionality.

See Ktoonzes' kernel for the SGS3 for example (http://xdaforums.com/showthread.php?t=1756776) With his kernel you can enable fast charging, however when it's enabled it disables the USB>computer functionality.

It's half an answer. Just like the rest of the half-answers.

I don't see the thread as how you stated it either, I see different ideas being thrown into the mix. Some worthwhile, some not, some feasible, some not. There may not be a 'magic bullet' of an answer, but perhaps at least an answer that whoever's doing this mod can live with while sacrificing certain functionality.

When I posted the pdf of the schematics, my hope was that someone with more knowledge than I (or a combination of people) could pinpoint other points on the board that could be used to connect the USB data lines.
[Nexus 7 General] littleguy77:
Yeah, you're probably right. I think I need to turn my subscription back from instant to once a day LOL. I get my hopes up every time I get a message in my inbox, then disappointed again. When a thread gets this long, it's bound to get repeat suggestions. And I was offering some of the same suggestions at one point. So my apologies.

I guess I just want people to be aware of the full ramifications of each potential solution. I think my post 4 back sums up my thoughts best. Just want people to realize that a software patch can fix one thing while wreaking havoc on something else. I know that for as much as I want expandable storage, I absolutely can't sacrifice fast charging. CoPilot GPS navigation, which is critical to me, simply drains juice much faster than a slow charger can provide. I learned that the hard way on a long trip :(
[Nexus 7 General] nst6563:
I think someone said that the pogo pins were traced back to the micro-usb +/- ....I wonder if it will fast-charge via the pogo as the one person has in the vehicle install....

and I agree...it is disappointing :( I'm going to solder in my flash drive this evening and just see what happens. I'm running cleanrom 1.25 with trinity kernel.

Most of the newer micro-usb connector cables you can just pop the plastic casing open and de-solder the data pins and the plastic casing pops right back together. If no one is sure what I'm talking about, I can see if I can post a picture later. The micro-usb connector seems to have a small circuit board with solder pads on it, very nicely labeled too I might add.

Maybe it's a possibility that there are different options in the kernel patch that can be changed. We need a good kernel dev to chime in on that type of patch ;)
[Nexus 7 General] littleguy77:
I've read many posts about the pogo pins. They're ground, 5v in, and stereo analog out. Meant for a simple stereo docking station to be released soon. Definitely not USB D+ D-. I think some people are using them to slow charge though, including the in-car charging people.

Re: the microusb plug, I picked up some of these a while back hoping I could stuff a microsd card inside. Close but no cigar. Could be useful for something though down the road.
[Nexus 7 General] nst6563:
I know they're not USB D+/-, I saw that from the schematics. I was just thinking of fast-charge via the pogo if they weren't connected to the micro-usb....but they are so the kernel patch/rom option to fast charge would have the same effect on USB operation.
[Nexus 7 General] bigbop:
If you look at the schematics (pg49 I think) there is reference to the +5v from the docking connector. It's a different input to the charging module than the USB +5v input so there is no shorting of data pins.

As to whether or not you can fast charge from the dock remains to be seen. Maybe someone can connect a charger capable of at least 2 A to the docking pins and see if it pulls 2 A close to it. At the same time, connect an OTG cable and see if that works. I think it will.
[Nexus 7 General] nst6563:
well I went to wire my flash drive inside and turns out I didn't have wires small enough. It'll have to wait until after my move is complete in the next week or two :(
[Nexus 7 General] seahorsepip:
What about the back camera connectors? aren't those data connectors?
[Nexus 7 General] bigbop:
Yes...for the rear camera. No USB signals there and no +5v either.

[Nexus 7 General] Kuchar09:
So did the root and cm10 kernel allow for charging?
[Nexus 7 General] JohnCorleone:
Wait, is that a USB jig you used there? I have one or 2 of those lying around. Is there a how-to for noobs because I could care less if I mess up the jig and I have a few old phones I can grab the micro SD reader from.

Edit...may not be exactly what I have but if someone puts a few of these together,I will buy a couple!

If someone could make a case/bottom dock that clips onto the bottom edge of the N7 and has a hub for Sim card, microsd reader, charging port.....I'd buy that in a heartbeat. Even if it needed a switch to choose only one at a time for power requirements.

[Nexus 7 General] Apocalypse487:
I just use a OTG cable with a 64GB usb stick. It's easier than this mod, but the mod is much better looking as a finalized product.

It comes in handy for large file transfers. Works with my S3 too.
[Nexus 7 General] Aleemz:
I ripped apart a cheap USB hub (£1) I bought from Poundland (do you guys have a dollar store in the US where everything is a $?) specifically for this. For the first one I made, I cut the board, like in the pic, but in the second one I made, I de-soldered the USB socket off the board, then straightened the legs. I soldered short wires between the legs of the USB socket and the micro-USB plug (OTG wiring protocol). Then I cut the side off of one side of those micro-USB plugs that are linked to above.

I placed the USB socket's straightened legs into the cut-out of the micro-USB plug casing, and positioned the micro-USB plug back in it's place within the casing. Once I was happy non of the wires were shorted, I filled the case with hot glue and then quickly clipped on the other half of the micro-USB plug's case.

The mirco-USB plugs I had laying around, and the micro-SD card reader I had in my drawer: http://dx.com/p/kawau-world-s-small...5558?rt=1&p=2&m=2&r=3&k=1&t=1&s=58477&u=25558

[Galaxy S III Q&A, Help & Troubleshooting] confus-ed:
Just purchased SGS3 and SGN10.1, havent downloaded any apps as of yet because I am not comfortable with the permissions issue.

I also have not rooted as I am waiting for my sandisk extreme pro sd cards, but i have some clarity i need in moving forward.

How can i best protect my phone and the info in it - mostly for the protection of my clients contact info and just the general fact that nobody needs to know my info without my knowing why.

I have been online for the last 5 days trying to understand what i need to worry about and what i dont.

I have a copy of whispercore 0.5.2 and would like to know if i can use it on my sgs3

Do i need to root my device to give optinal protection PROS/CONS

How is the avast protection

And most importantly - are these protections necessary or have i been sidewiped by chicken little?

How can i determine the best app for me - preferrably with no permissions

I really need a good mail app, document editing app, pdf app, and possibly a CAD app

I have been overwhelmed with info over the last 5 days and need some help with clarification and facts.

Thank you in advance for your help,

Confus-ed:silly:
[Galaxy S III Q&A, Help & Troubleshooting] ghostofcain:
An app with no permissions has the ability to access nothing so in essence will be of little use. Contacts are synced with Google unless you opt out that decreases security. Personally if your clients details are that sensitive use a dumb phone for work and keep your S3 for less sensitive tasks.
[Galaxy S III Q&A, Help & Troubleshooting] confus-ed:
Are you trolling me?

Just running through the threads trying to increase your reply and post count?

I would appreciate that if you dont have any real information to share, dont waste my time with your non-answer.
[Galaxy S III Q&A, Help & Troubleshooting] nodstuff:
What?

He answered your question, an app that asks for no permissions can't do much, apps need to have permissions to do various tasks.

If you're that paranoid about safety don't root and just use reputable apps from Google play store.

Edit: in fact the more I read you reply to him the more I see that you have a terrible attitude.

Good luck finding help when you act like that.
[Galaxy S III Q&A, Help & Troubleshooting] confus-ed:
No attitude, i thought that i had explained in my original post that i have just spent 5 days scouring the web (which included xda).

I didnt ask about permissions nor did i ask about contacts being synced with google, I understand what the permissions do, but i also have read where you have control over the permissions when you root the phone.

Not paranoid, I just know the data mining that goes on and i am sure that my clients wouldnt want some random solicitation due to an app that has no need to access my contact list. such as a document editior.

My reply may have been a little short but ghost did not address any of my questions or concerns. :confused:
[Galaxy S III Q&A, Help & Troubleshooting] nodstuff:
Yes you do have control permission when you root, but rooting is a double edged sword because root apps actually have more "power" when it comes to your system and if there is malicious code in them it will also have superuser permissions if you give the main app superuser permissions.

The safest option is not to root, if you root you are opening your system up to exploitation.

I have rooted every android phone I have ever had and never had any problems but that choice is yours.
[Galaxy S III Q&A, Help & Troubleshooting] sir_earl:
From the perspective of data mining, you're basically just as vulnerable with a non-root app, then only difference being that the non-root app will specifically ask for permissions to use your contacts.

At the end of the day, if you want decent integration between your personal data and your apps, you're going to need to accept some risk and allow someone elses code to run through your data. If you have sensitive client data, you'll most likely be safe if you stick to mainstream, popular apps, and keep a close eye on comments to make sure no one else has had issues with security. If you're really paranoid though, I would recommend you don't keep sensitive information on any device with internet access.
[Galaxy S III Q&A, Help & Troubleshooting] Krep3:
I would recommend LBE privacy guard it will prompt when an app is trying to access something and you decide to allow it or not, you can manage wich permissions you allow for each app, even cut it from any Internet access.

The app does require root to work
