Samsung Galaxy Tab 10.1 external microSD project

Hi, several of we GT 10.1" tab owners over in the tab specific area are looking into adding a external micro SD to our tabs. I am hoping that we might find some more expertise and input in this section of the forum.
The ongoing thread we are discussing the mod in can be found here: http://forum.xda-developers.com/showthread.php?t=1600661, but hopefully we can merge the threads, or somehow keep things straight, but it seems this may be the more appropriate forum section.
Brief recap is that it appears the early/pre-release GT-P7500 had an external SD card. My later model GT-P7510 has the associated area on the MOBO unpopulated. I found the connectors, the OP in the thread found the factory SD card holders. I used my tab for a test, soldered the the connector on, and early indications are it is not functioning. So far I haven't been able to dig back into it, but common consensus is that the unpopulated area near the SD reader connector is needed. I have a lot of experience with simpler analog electronics, and analog design, but to repopulate the needed components with no idea of where to start is beyond the scope of my abilities.
We have the GT-P7500 service manual, at least most of it I think. The MOBO photos in the manual show the area populated, but the photos are to low resolution to gain any useful data. I found some supposedly leaked FCC photos of the tab disassembled pre-release. It also shows the SD card area populated, and this one shows the SD card holder as well, but again low resolution.
Currently we are hoping that maybe the very early HW revisions of the 3g GT-p7500 may have had the SD card area populated, and possibly one of you owners could help us.
If anyone has any input, or can help build the circuit from the ground up I am happy to provide any testing/data/pinouts I can.
On a side note-- does anyone know how many times I can disassemble my tab without ruining the case?
Thanks in advance folks!

In addition to any missing components, you need to figure out which SDHCI interface of the CPU that is hung off of and add it to the platdata:
https://github.com/pershoot/galaxy-2636/blob/ics/arch/arm/mach-tegra/board-p4wifi-sdhci.c#L296
Looks like 3 is the internal eMMC, 0 is the wifi chip (BCM4329 and 4330 are SDIO wifi chipsets), 1 and 2 are not used.

I too have been toying around with this idea. Looks like I'm not alone in thinking this tab would rock with a microsd. Only you guys are way farther ahead than me! Also I know for a fact that the gtab 10.1 v2 that's coming out sometime this year will have an SD slot. And it looks like little else that's different. Maybe when one of us gets our hands on it we can see on the inside where things are populated or not.

Turns out that you're most likely wrong on this - all evidence (including the recent source release I believe) indicates the Tab2 10.1 will be OMAP4-based just like the Tab2 7.0 is.

interesting thanks

Looks like I will finally have some free time to open my tab up again. I plan to ring out the SD card holder to the connector, and then on out from there. I will go at least as far as the unpop area if that is indeed where it leads. While I have it open, do you folks have any suggestions as to other testing or mapping to do? I appreciate the input so far-- I don't really know much about the software side, but we can burn that bridge if/when we get there. Will keep you all posted.
Later,
Jason

Hi! Do you know that if you add a sd-card extension, you must develop new drivers and kernels? And this could probably make you lose your warranty...

SD card
why do manufactures insist on leaving sd card slots off the build? doesnt seem like it would cost to much include one.

thanks for this

Hi,
My friend has a 10.1 GT 7500,
He bought an external adapter for sdcard.
Perhaps you can use the layout schemas from such a device to discover what you need to make it work internally.
Its probaply the same "signal wires" but now abvailable on the external connector.
Hope this helps/.

Yes, thank you. The tab has been rooted and running experimental roms from ~6hrs after I bought it. Warranty has been void for quite a while...

I doubt so much that it is the hardware costs, although it would add up to a significant amount, but rather due to the desire to sell the more costly tabs with more internal memory. After all, why would the you buy a 64gb tab for $200 more than the 16gb one, when you could throw in a 32gb card for $30? It seems pretty clear in this case, Sammy had developed the tab with external SD. There are lots of photos floating around of the pre-release tabs with slots. There is some evidence that they planned this nearly to the last minute, as we are buying the factory holders which "don't exist" on ebay. Unless they could not get the SD reader working properly or had more issues than the time solving was worth, then I think all things point toward this being a plain and simple money move.

I appreciate the input, I have the Sammy autherized adapters. These all use the USB OTG protocol, and I think it is unlikely that the hardware will be the same. I will deffenitely investigate this though.
Thanks,
Jason

If you don't succeed with the adapters you could do what i'm trying to do with the Kindle Fire. I'm building in a microsd adapter for use with USB host.

Since I don't have a Galaxy tab I can't really be of any more use, sorry.

Hyundai T7 review

Disclaimer: I have no vested interest in you buying one of these.
I just got one of these about two weeks ago. So far, so good especially given the low price. The only serious downside is the battery is on the small side but unless you must watch streaming video for hours at a time, probably not going to be an issue. Screen is very as is the ability to have SD, hdmi and a usb port that actually works. It only has ICS on it and I think the build date is jan 25. But my best guess from trying to decipher the chinese or korean Hyundai website is that they will have a JB update after the official release at MWC. Device also appears to be built by Samsung but not 100% certain on that. If you want a lot more details about it (way more than would be appropriate) here http://www.gedankenexperiment.dk/pivot/entry.php?id=865&w=rant

I just bought a Hyundai T7s via an Amazon reseller in the UK, and it too works very well indeed. It's hard to believe it's so much cheaper than a Nexus 7 and yet has USB on the go and so on working right out of the box, not to mention a micro sd card slot etc. The only pain so far is the dedicated charger - it's a shame it doesn't charge via micro usb. Exynos Abuse root method works perfectly which is great.

Apparently charging by USB is possible but has to do with the current provided. Check the T7 thread at slatedroid.

Huyndai is one of the best companies worldwide.

[Q] Alpine ICS-X7HD and Samsung S4 issue

Just so that people will know what up.
I bought one of the ics-x7hd units and i do love it. The mistake that i have is that i thought since i am getting this new unit and since i had a Samsung S2 phone why not go all the way and get the new S4 model. The phone is great! The unit is great! the problem is that they are not great together. (Yet) all of the bluetooth features like phone, Pandora, and music work fine. Drive link works great as well until you plug it into the head unit. It will start to work and show the dont play with it while driving screen but once you hit agree it will shutdown and display an error on the phone. I have called Alpine and they said that they would look into to it but who knows how long that will take. I would feel worse but they also do not currently make a plug that works with the new Iphone 5."I read that from an iphone user via Crutchfields site. I am happy with the unit and it produces great sound quality just be aware that if you want to use it with the Samsung S4 its gonna bit a while.
If anyone has any feedback or solutions i would love to read it.

Update on my post
Just an update on my original post.
I was able to side load a copy of Drive link 1.1.028 and it work with my Samsung S4. Now that it works i have a ton of things that i would change about the drive link app but it does do what it claims to do. Simple app that does a few features but not nearly designed to work at its full potential.

Hey I just got a ics-x7hd and I can't get my Samsung note 3 to link to it at all.
Can anyone help?

just got my new nexus 7!

Hello all.
Just wanted to share my experience with my new nexus 7 tablet. I picked it up at bestbuy Friday since it was tax free weekend here in Tennessee. I must say I am very impressed with this tablet. I had the original N7, and sold it 2 months ago to purchase a 32 gb nexus 10. I fell in love with the N10 immediately. It was by far the best tablet I had ever used. Well, this new N7 is just as good if not better. I will say, it is hard to compare the two because they are vastly different animals. I personally think the new N7 beats the N10, especially spec wise, but with the difference in screen size, these two tablets are really designed for completely different tasks.
One thing I have not been able to sort out yet is being able to use usb storage with my new N7. I am able to use my external hard drive with my N10 as well as my new Macbook air and even my Galaxy Note 2, but have not been able to use it with my N7 yet. Furthermore, I am also unable to get my Macbook air to recognize my N7 without booting the macbook into Win7. Sometime in the near future I will root the new N7 and install stickmount and see if it will recognize usb storage. I have not
researched a root method yet for the N7 but I'm sure there is one available, and if not there will be one soon. Most likely this will fix my usb storage on the N7. Still kind of stumped as to why my Macbook will only recognize it when booted in Win7.
If anyone has any questions about the new N7 feel free to post or shoot me an email at [email protected]. I don't mind answering any questions you may have because I know personally I like to do as much research as possible before I buy a new piece of electronic equipment.

Droid Nas app will make it easy to transfer files in between your Macbook and your Nexus 7. I haves used it on both models.

Tax free weekend in Tennessee? Is that a normal thing that happens? Curious!

Wileyfox Storm USB OTG Support?

Hi guys. So I'm considering buying a Wileyfox Storm because of the price/value ratio.
There's not much information that can be found about the phone regarding it's OTG support on the internet. Some comparison sites imply NOT, and other sites have something cryptic like USB OTG (TBC). LIKE WHAT?! For that matter, there's not that much info and support for the device at all, nevermind any nongeneric cases or covers.
Anyway since I couldn't find a definite answer, I wanted to ask the actual owners of the Storm if their device supports OTG if they've ever tried it. And if you haven't ever tried testing it, would you mind doing so?
Thanks guys!

I installed USB OTG Checker which showed my Storm has the USB OTG API. However I can't test for USB OTG Kernel or Driver Signal as I don't have a USB OTG cable or adapter at the moment. Hoping to borrow one or buy one in the next few days. Will let you know the outcome.
Regards.
Brian

I received my £0.99 OTG USB adaptor in the post from an eBay seller today and it works. With ES File Explorer or Solid Explorer it shows the contents of my memory stick and I can read text files, etc.
So the answer to your question is yes the Storm does support OTG.

Hi Brian,
That's fantastic! I really can't thank you enough for taking the effort of experimenting the OTG feature on the Storm :good:.
If you don't mind I'd also like to know your thoughts on the device and if you'd recommend it. From what I've understood is that the battery is probably the biggest disadvantage in the phone, but how ''bad'' is it actually? How often do you have to charge your phone under a certain usage?
And also I don't know if you use it for gaming, but if you have done so, does it perform decently?
Thanks mate!

I've had my Storm since Christmas and I am generally pleased with it these days. The last OTA update made a big difference to the reliable operation of mine after a bit of a wobbly start but I have read that others have had a few hardware problems along the way. I don't know if it is still the case but I haven't seen any new complaints recently. If you are going to buy SIM free I would play safe and get one from somewhere like Amazon who have good returns policy if you do happen to get a "lemon".
My previous phone was a gen 1 Moto G running Cyanogenmod and battery life with my Storm is equally good but then I am a very light user and I can get about 2 days out of a full charge. However if I run Google Maps for my daily commute the battery goes down quite quickly which I suppose is due to that big display being on all the time but probably no worse than my Moto G was. The Storm is quite responsive but I've never used it for gaming so you wll have to ask others about this on this forum. The Cyanogen Mod forum is also worth reading through:
http://forum.cyanogenmod.org/forum/1212-wileyfox-storm-kipper/
I'm very pleased with mine for what I need it to do but like others are saying we do need a decent case for it.
Hope this helps.

That was pretty helpful thanks. I'm stuck in a dilemma now. It's either going to be the Storm or the OnePlus X (roughly the same price).
The OP X does rock the more powerful Snapdragon 801, however the bigger screen, front facing camera flash and 32 GB of internal storage on the Storm seem to be dragging me towards it immensely.
Also the OP X has loads of support and threads going for it while the Storm seems to be nearly dead on the internet.
Which would you honestly get if you were phoneless and had to choose one of the two?

It is early days for the Storm but Wileyfox the company seem to be more intent on pushing the brand and new sales rather than nurtering and building up a strong reputation. In theory Wileyfox being UK based should have the better customer service but many people haven't found this.
The OP X has as you say a strong following and seems a better phone than it's earlier models with a more straight forward means of purchasing it these days. I like Cyanogen having used it for many years on several mobiles but I don't know much about Oxygen OS on the OP X? OP phones have been on the market longer, hence have sold more phones and consequently there will be more information on the internet. I think they have had their share of hardware problems in the past but perhaps this is the risk you take with good value mobiles like these.
One of the things at the top of my list was what to do in the event of a hardware problem and I thought with a few retails here in the UK and Amazon stocking the Storm it might be a safer bet and I have read on here about people returning their phones to Amazon at least once. When I bought my Storm at Christmas I was also looking at the LG G3 (i think it was that one) which was on special offer but went for the Storm mainly from the reviews I'd read. Although I am perfectly happy with the Storm reading other posts on here makes me wonder at the longevity of the Storm but this is probably the case with the OP X too. Only time will tell.
I wouldn't want to advise on which one to choose but perhaps make a list comparing the things important to you and then follow your heart. At least that way if you are unfortunate enough to have problems you will know that you made the best decision at the time.
Good luck.
Brian
