ebay smartdock clone - Galaxy S 4 Accessories

On my quest to make an adapter to use my Atrix Lapdock with my S4 I already destroyed an mhl adapter, and now I want to try this dock from ebay.
Has anyone had any experience with it?

Let me know, looks nice.

Be careful. I bought one of these on Amazon a while back...
http://www.amazon.com/gp/product/B00C4CVT7A/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1
...and I realize it might not be the same exact thing, but it looks similar in construction.
About 2 weeks after I started using it, it started shorting out and sparking! I was lucky that I was right beside it when it started happening and got my phone out of it before any damage was done. The problem was with the wiring / circuitry in the base of the unit. I threw it away immediately.
So, hopefully your will work a lot better, just be careful.

Thanks for the info. I usually buy stuff from DX, so I'm quite used to opening and doing a good quality check for every item I buy before using it!

I got the item, it works good and the build quality is good.
BUT, when you connect an external power supply, the power to the usb host port gets disconnected and the usb lines get shorted. So you can use either the USB OR the HDMI. There are 3 relays inside the device; by disabling the top one you can do the 500ms short trick and get the HDMI + USB HOST + CHARGING features, but it takes some effort.

Are you able to use or make a charge only cable (only 5V and ground)? That way the USB data lines should not be affected if the charger shorts the data pins.
Or is the one of the relays shorting the data pins inside the adapter?

Sorry, maybe I didn't explain correctly. The adapter shorts the phone's usb data pins, everything else is untouched. A delay circuit is implemented too, so it looks like they tried to do the 500ms trick but failed miserably so they sold the dock as is.

has anyone got any further with this project? I have an original Samsung smart dock and have now got the hdmi converters but nothing is shown on the lapdock screen. The adaptors and lapdock work fine as I have had it connected to my sky hd box?

Hi, did you try the adapters with a TV? My adapters work well and send a (distorted) image to the lapdock..

Yes I tried them both ways as an output to a tv and also an input to a moniter

looks pretty interesting. huh

HTC Desire microUSB Cable fragile...

In one week I have succeed to break my microUSB cable that came with the Desire, the USB-Brick is probably due to manipulation with those type of weak cables for sure it can't help. I'll get a new one (or two). I guess my pile of 20 miniUSB is useless now...
The Odd is that it can charge upside down
yeah very rare, ive never managed to break my cable and my cable has been through a lot including using it as a belt along with holding a pair of ladders down on the top of my car

Are you serious?
This isn't exactly Sonim.
Still, how exactly is the OP's cable damaged?
P.S. I'm also pissed that my collection over way over 100 miniUSB cables seem to be all too slowly becoming redundant. Before my HTC Desire, everything was Mini, not I'm forced to carry both types around. I'm considering making some neat little converters for my other devices.
Can confirm.
The cable that came with my Desire (more wire than cable) is crap.
It broke within the first week.
Nearly no strain at all, cable break at the USB plug.
you can use a mini to micro USB convertor instead of carrying both wires around

Yes i am serious, i have been using the original HTC cable that came with the phone and an additional two official HTC cable for desire just fine. I dont have any problems with them and yes i have used them as belts and cable ties.
The only way i can see you ever damaging one of these is if you damage the end or the cable you have might have been faulty from the start or near broke.
I just tried to bend the end of mine a few times and it still seems to be working, i did a few file transfer tests and it doesnt work any slower or faster.
out of all the desires or htc phones sold with a usb mini cable your the only person to report this?
The same thing happened to shadow and my cable broke during the first month as well.

mine does too
lol
you can fix a usb brick easily and ppl if ur plugging the phone in to the front of ur computer try a different port preferably at the back
I already broke several cables. Now one on of the pins of the Desire's micro-usb connector broke.. I for sure am a bit hard on my equipment but this never happened with micro-usb. I also think it easily breaks because the cable does not fully connect with the Desire's micro-usb connector. It sticks halfway in.
Anyway, I can no longer connect via usb and with all the dents and scratches it will probably be very hard to get repaired under warranty.
Mine works fine, but my mother's stopped working without visible damage.
Mine failed too, Its fussy about charging and very rarely works for USB. I think its the microusb<->cable connection that fails because its not moulded like most cables.
I've got a cable from a blackberry now (it was lying around, ive never had a BB) which works fine for charging and USB, the moulded connector seems better and the cable is much thicker.
I'd rather the cable or connector broke than the port on the phone (which is what microusb is designed for)
I was wondering if they can be fixed?!
YOU"RE RIGHT, they're flimsy.
These
Code:
[URL="http://www.amazon.com/gp/product/B004W3LKZ0/ref=cm_cr_rev_prod_title"]cables[/URL]
Look sturdy but break too easily. Not as cheap as most chinese made but these cables usually break in about 2 months for me. Dont even think about folding it and putting it in a bag for those frail,dying HTC phones.
I wonder if the cables are easy to fix... its copper right?
-Can anyone recommend a simple way to handle these wires or a more durable wire? I dont want to buy one every month. I'm thinking about http://www.amazon.com/Micro-Retract..._19?s=wireless&ie=UTF8&qid=1328931599&sr=1-19.

I am thinking about it. It costs about the same to just buy the micro cable. This has 30 days. http://www.ebay.com/itm/Mini-5-Pin-...262914?pt=PDA_Accessories&hash=item3f13828e82
my usb cable rubber is also starting to split at the ends. but it still works fine.
Never broke it but...
I never actually broke the cable, but I always found it very loose. When I insert the microUSB into my phone it doesn't click or anything. It just sorta lays there. It is not very stable and I am always terrified when messing around with something that requires a stable connection (alpharev, root, etc.)
Am I the only one experiencing this, or did I just get a lame cable?
USB conector
I've never had trouble with my htc cable, but I've replaced the usb port twice on one phone and once on the other. (yes I have two desire's)
I too wish it was a deeper port.

Droid Charge HDMI, how to?

How do I get the HDMI working on the charge? I don't see an option for it anywhere, and I didn't get a prompt when hooking up my phone to the TV

plug the cable into your device and then into your tv it will work automatically. there is really nothing to be done on your end except making sure your tv is on the right input and you are using the correct cable.

This is the cable I bought: http://www.amazon.com/gp/product/B003VWYBC2
Works great, don't need to touch any settings; just plug in and go.
I did read that this cable has issues with HDMI 1.4 so if you have a brand new TV, you should look elsewhere.
I just picked up a cheap cable at Target. It works flawlessly. As started before, make sure the cable is hooked up to the right input, make sure the phones screen is on.

What do u guys think of this?
I would suggest not taking a gamble with an adapter, which can always introduce extra problems, when you can get a complete 3' cable for less:
http://www.monoprice.com/products/p...=10253&cs_id=1025301&p_id=6973&seq=1&format=2
Or a 6' cable for about $1.50 more:
http://www.monoprice.com/products/p...=10253&cs_id=1025301&p_id=6974&seq=1&format=2
There are a bunch of other lengths and options on MonoPrice, as well, and whichever way you go you'll be better off than overpaying in a physical store.
Doesnt work?
I did this on my charge, plugged into phone and then tv. Still says no signal? Cable is brand new from monoprice. I am running a different kernel and ROM, could that be an issue?

If you're sure you're on the right input and wiggling the cable in the phone doesn't help you could have a bad cable. My first one crapped out within seconds of beginning to use it.

Your TV might not like the signal the phone is putting out. My tv, which is a dinosaur in terms of 1080p tvs (its actually the first one to market, and has a DVI input) is finicky with certain resolutions, and alas, my droid charge through hdmi does not work either. Try a different TV to rule out a bad cable...
Quick question. Does the image mirror the resolution of the phone? Because whenever I hook up my charge, it seems to be missing some area on the top and bottom but I'm thinking this is justthe resolution of the phone.

[Q] USB host mode, specifically via Nebtop

So, I purchases a USB OTG cable in an attempt to try and expand the functionality of Webtop while using Nebtop. I've been unable to get any response from the phone when I plug in this cable. I've tried my wireless Logitech mouse and keyboard that worked off the bat with my TF101 using the Unifying remote they came with as well as an external TB drive.
Has anyone else had any experience with this? It seems logical that the phone supports host mode since the actual dock has 3 full sized USB ports.
All the information pertaining to this sort of thing I've come up with seems extremely phone specific but if there's a simple solution I'm missing thanks all the more.

The problem actually lies in the usb port of the phone itself. The dock was designed for this purpose, and the dock app handles most that for you, the one thing that the dock is able to do that a straight USB cable can't do, is provide enough "bus" power to use a mouse or even a USB stick directly from the phone. If you want to use a Mouse you will need to get a dock. I got mine directly from wireless.att.com, and it was only $49.00 back in Nov. when I got it. It works VERY well with webtop.
P.S. Motorola is very famous for doing things like this to force you into a dock, or to lock out certain features that everyone really wants to use.
I made my own dock by using a powered usb hub I had sitting around (it was actually the one that came with Rock Band for my Xbox 360). I did have to modify it slightly so that the 1 pin was powered from the 5V (a simple shunt from the 5V inner pin of the power supply solder joint to the solder joint of the 1 pin worked fine--although it might be wise to insert an inline fuse since it also charges your phone while plugged in).
Otherwise, the only other thing needed is coming in the form of your otg adapter that should short the 5 pin (common) with your 4 pin (ID). I did this by cracking open an extra micro usb cable and soldering a wire between the two.
So, my setup was like this:
1. Modified usb cable to short the 4 & 5 pins to let the phone know to go into host
2. Use a female A-female A usb coupler to join the usb cable to the powered hub (I got mine here from Monoprice
3. Get 5V to the 1 pin in the usb hub to provide power to your phone and for whatever is plugged into the hub.
With this, I was easily able to run a usb mouse and a wireless keyboard that had a usb dongle. Paired with a micro hdmi cable to hdmi-dvi adapter, I am able to use my office monitor and the webtop linux. I honestly haven't really used it much yet (if I found it really useful, I probably would have just paid for the dock).
The obvious easy way is to just get the dock. However, I really like being able to do this on my own and since I had this stuff already laying around. Also, the cheap prices from monoprice (I actually made $4 off of the purchase from a PayPal bill-me-later promotion).
So, you should be able to get it to work if you get power to the bus on your usb (but again, it might be safe to pass an appropriate fast-acting fuse, ferrite core, or something to protect from surges). I haven't had issue yet, but I also don't use it often...yet .
It sounds like a bit of yes and a bit of no. The OTG cable I got is microUSB to female full USB, am I going to need to modify this cable as you've described by crossing the 4th and 5th pins?
I'm thinking about ordering this "7 Port USB Squid Hub" since it has the 5v power adapter, do you think it might work?
Just one more question and thanks for all the help but should I not see any response from the phone when I plug in the cable? I read through some of the reviews for cheap cables on Amazon and apparently sometimes they're just useless.

The OTG cable have should work. The OTG cable, to my knowledge, should already have pins 4 & 5 shorted together. I'm not completely certain, but if it's designed as an OTG, it would probably already have that done. If you have an ohmmeter/multimeter, you could try to check (it's hard to isolate the small pins, but you can try). If it's already going to the USB female (type A), you will then be able to directly attach your hub when you get it (without the need of the coupler I had to get).
When I used mine, there was no notification that said "Hey, I'm in USB Host Mode!". However, if you successfully have a mouse attached, you'll see a mouse cursor arrow on your screen.
Have fun with it and if you can't get it to work, let me know and I'll try to explain with even more detail (perhaps with some pretty pictures) of what I did. I more or less went off of what I could glean from reading what others did.
It works great! Also, it is weird to see the mouse on this little a screen, it seems oversized.
I just plugged everything in and it worked off the bat. I'm using just two items from Amazon I got for under 12 bucks (plus, of course, the keyboard and mouse I already had for my computer). I don' think I can post links to the forums yet but the ASINs for the items if people want to do this on the super cheap are as follows:
B0043TBCDS 7 Port USB Squid Hub, a whopping $5.19
B005N55WHI Micro-B USB OTG Cable... $5.99
I chose these because of their Prime eligibility and also for their form factor so as not to cover the HDMI port, I bet it's not impossible to get these even cheaper.
While this isn't technically a replacement for the dock since I had to root the device and I have to press "Load" in Nebtop if I want to go to Webtop I'm extremely pleased with the results.
I also love that all the soft keys are available. The ones I've discovered are that right button on the mouse as well as Esc are Back, the Home key is Home, clicking the wheel as well as Ctrl, Cmd, Alt and a whole slew of others bring up the Menu, but all I can find is F5 for Search.
On another note, while the phone does charge when hooked up, a practical boon, the screen still times out despite having the "Stay awake" feature checked. This is annonying when the phone is on it's side accross the room and I have to squint to see the cursor and swipe it unlocked sideways as well as click back into Mirror Display.

USB OTG killed my S3

I'm just posting for brief warning/general info for you guys. When I got to work tonight I plugged in my USB OTG cable which I have been using w/ no issues on both my N7 and S3 since July and then plugged in a 64gb flash drive that I have also been using since launch. When I plugged in the flash drive, I heard a pop, the screen went blank and the phone is totally dead. A quick search showed while this isn't incredibly common, it has happened to several people. Most blamed the OTG cable, but I disceted mine and it had no broken wires and no shorts. I turned up a thread on root wikiz that basically said that it is the power management IC self destructing and there is nothing that can be done to repair it. So, just a heads up if you use OTG-- I am not sure I will use it again on this phone as it seems it is just a matter of time...

This happened to me. Verizon will warranty the phone. I wondered what actually blew up in the hardware. I am surprised it hasn't happen to more people, seeing how you really don't have any control over whether it blows up or not.

Sorry to here about your phone. I was jut about to go buy one of these cables.
This same thing happened to my phone a few weeks ago. It went totally dead out of nowhere, I was taking photos at the time.
You shouldn't have a problem getting a replacement even if you don't have insurance.
Good Luck
I have heard stories about that happening, though its not common, it is surprising that its so low considering its random and no one knows exactly what causes it
at least you don't have to factory restore before returning
Sorry guys, I just woke up. Was on graveyard shift last night. Anyhow, the cable was a generic ebay right angle otg cable, about 5" or so in length. I am 99% certain it had nothing to do with the cable though, just a hardware problem. As mentioned above I dissected the cable and it had no problems. I could still use it on my Nexus 7 with no issues. I had the cable plugged in before inserting the flash drive and it was fine until the flash drive was plugged it.
The Root Wikiz thread I mentioned said that someone had sent theirs in to be Jtag'ed thinking it was just hard bricked. The response from the people where he sent it was that they had seen a number of them with the PMIC damaged and that there was nothing that their services could do for them.
My guess is there are some marginal PMIC's out there and that when they switch the port from charge to host mode they just cant take the current and pop. The fact that I made it nearly 5 months using the same OTG cable on a regular basis kind of lends credence to this theory, but who knows. All I know is that it was totally dead, absolutely no signs of life regardless of what I tried.
FWIW I was rooted and running paranoid android, but I have found reports of this happening to bone stock phones as well as any variation of ROM. Verizon did warranty the device. Oddly, the tech told me "I have never heard of this happening" but didn't even ask me to try anything with the phone, he just said that they would ship me a new one for warranty replacement.
New device is here, I'm off to root and unlock! Good luck guys.

Wow, that sucks, but I am glad you got another S3. I have been using this one that I got from Amazon. It has a couple of usb ports and 2 card readers. I have been very happy with it. It is extremely useful when I am at family functions, and everyone has taken a lot of pictures and video. I can grab their cards and pull the pics and video onto my 64 Gig SD card on my phone. People are amazed I can do this with my phone! However, now I am a little worried about using it. I will keep this in mind, and only use it on the occasions that I really need it. Thanks for the heads up!

One day charge is normal if using phone. If gonna use OTG you are overusing and can expect 1/2 day. Buy good cable if want data.
I had something similar happen except, my usb sent a static spark from my oc to my phone. Didn't fry it completely, but messed up something that would no longer dock to pc, dock to car our go into deep sleep.
Wonder if the two issues are related.
Be sure to discharge any static in you usb called before plugging them into your phone.

your right..but its used for 3 days....i bought an otg cable and use it...thats amazing...i can use mouse,keyboard and other devices in my s3.
but i still have my problem...
my s3 is in flight mode and and doesnt do anything...but its discharging..and i dont know the problem is sent from my os or my hardware..
idont kno that the os is screwed up or is something wrong with battery.
is there any command that tell os to dont discharging???

Discharging is what the battery always does when not plugged into A/C power and turned on, and even sometimes when it is plugged into A/C power (when you get in the top 10% of full it starts going through discharge/charge cycles to keep it within the top 10% of power but never totally full. This prevents overcharging and explosions)
That said:
A sudden reduction in the runtime for the battery under the same average load is almost always the battery going bad.
If you mean the battery doesn't last as long because you now use OTG - those things you plug into the phone need to get their power somewhere. The phone battery is it.
So now you are powering the phone + whatever other things you attach to it. Some of them can drain a lot more power then you might think. You just never noticed much (if at all before) because your total reserves weren't such a tiny amount.
If you stop using OTG devices and your battery capacity bounces right back up to where it was before, then you can reasonably infer the extra gadgets are the culprit.
(if you stop OTG stuff for a few days and the battery still sucks when before it didn't, probably need to buy a new battery because yours is most likely shot.)
Assuming it seems to work fine...
So two choices, right? No accessories and lots of battery life, or lots of accessories and no power to run them with.
well...not really:
It's probably not always possible - but how often do you use OTG near A/C power?
Whenever you are near somewhere you can plug in, the first thing you should plug into your OTG cable (besides the phone) is a USB hub with a power cord.
...and really, if you want to use those power hungry USB hard drives and things like that, then you really can't without taking the stress off of the phone of supplying that power - that hard drive just half spins up like a car that cranks but won't start.
Every crank in that car wears the battery down and beats up the starter when it doesn't fire up the engine. Just like every spin up but not quite read of the hard drive puts incredible load on the S3 to try to throw enough current at it fast enough to keep it happy. Just beating it up for nothing.
Which brought me to what I wanted to bring up for some consideration:
Think about trying to use a powered hub whenever you can as the first thing off the OTG cable, should take an immense amount of stress off of the S3 in making it all work.
Bet at the least you reduce the risk of popping since the power spikes will be much less - that powered hub is a pretty solid buffer for that kind of stuff when you are constantly popping flash drives in and out.
I remember way back when for the Nook Color when some really sharp people made OTG happen out of the thin air - no way Barnes & Noble had that on even a remote list of possibilities when they were ready to throw the device to the masses and see what happened.
If you wanted to use more then the smallest of thumb drives you needed a powered hub. The device wasn't designed for it, and simply wasn't able to squeeze more then a paltry amount of power out in reverse. (but it was just enough to talk to a powered hub...)
Anywhere that you can plug in your powered buffer should contribute to avoiding the problem the OP posted about. The thought experiment (hopefully) growing from this post? How much truth does this theory exhibit?

hi everybody....
i have an issue with my s3....i make an OTG cable and plug it into my s3...and i just can get power from it,no data.
but i think the s3 is already wasting power and i must charging it after a day.
can anybody help me!!!!!

Here you say you made an OTG cable, the first post I quoted you in you said you bought one. If you made it, i'd say that is your problem.
The quality of the cable you use absolutely matters. Higher quality parts = higher quality results.
I have a bunch of micro USB cables (as i'm sure many of you do also - ) ... and from some of them I get an absolute night/day result in charging.
Some cables (mostly the ones from the dollar store or older cables) just plain suck. They can't bring enough power from the same A/C adapter as my OEM HTC/Samsung cables. (I have some motorolla OEM cables from around the time of the droid X launch - they are closer to the dollar store cables in quality - haven't tried recent motorolla OEm cables, hopefully they got better or I got a bad batch over a six month period)
Using the low quality cables I can absolutely lose power plugged in just being a wifi hotspot with the screen on, until it eventually goes critical and dies. (this I tend to notice when my pc banished to the corner of nowhere loses all network connectivity) - whereas with the HTC/Samsung cables from within the last two years keep me near full with that being the only difference.
I'd rather have a few good cables then a bag full of POS dollar store ones. That little bit better material, little bit tighter QC adds up to a big difference in the final outcome.
This same thing happened to me when I plugged the same type of cheap right elbow OTG cable from ebay into my brand new S3 (2 days old with about one hour of usage). The cable worked fine with USB drives, a mouse, or a keyboard used alone on the S3. The cable was plugged into a USB 4 port hub with multi-card reader. The screen was off when I plugged it in so it appeared to just be off. Any attempts to power it on were fruitless. I smelt the phone right afterward and there wasn't any burnt smell. Plugging in the phone resulted in it getting pretty warm but not to an extreme yet the battery remained cool. It appears to have burnt something between the battery and lines but leaving the components intact thus causing the excess of heat. BTW the hub/reader is fine. I won't be using that again on my new one but I will be attempting to use a different hub that has been working fine on my wife's RAZR MAXX HD. Just hope this is a very isolated incident and not a bad batch from the retailer.
Edit: The S3 is a blue 16G Verizon model. The S3 was on stock ROM when this happened (not like that would prevent death from inferior circuit protection components).
Were you using a powered hub, or passive hub?
Anyone tried a DAC off the OTG cable?

Don't do it. I've fried 2 GS3s with a UCA-220 DAC over otg.
First time with a regular OTG cable, the second time with a OTG/phone charging cable, the power came unplugged and zap. I'm lucky Verizon has replaced the phone two times.
I think the best solution is to completely isolate the DAC power from the phone power. A circuit to charge the phone with the otg/charge cable and a separate circuit to power the DAC.

Wouldn't use of a powered usb hub remove any power issues? I purchased a OTG cable today.. I had planned to connect it to a powered hub, and run the DAC off that?

Permanently bricked Nexus Player

Thought I would share my experience so no one else repeats this. I bought a micro usb ethernet device so I can hardwire my nexus player. Connected it to nexus player and it did not work. The ethernet device had an extra power cable for it. Thinking it may need more power, I foolishly connected power cable. Now nexus player doesn't even turn on (powerlight off). I'm afraid I may have shorted the motherboard. I was able to open up nexus player using guitar pick....but don't even know what to do. Spent alot of time tinkering with it too. So sad as I am now left with an oversized hockey puck Lesson learned.
Look for black marks or brown you can also take a multimeter and check components you would want to check any smd fuses first then trace back from the USB plug. I don't imagine that killing the whole thing. Does it respond at all?

Did not see any black or brown marks. Unfortunately it does not turn on at all. I'm getting desperate and am thinking of buying a new 12v 1.5 amp adapter. Do you think that may work? Thanks for your input.

I don't think so if hypothetically the Ethernet adaptor delivered voltage to the usb port on the nexus player and now with just hdmi and power plugged in it wont turn on i doubt a new ac adapter will fix anything.
You can check your current adaptor if it is broken by using a multi-meter to see if it is providing 12v.
Can you link the Ethernet adaptor you tried to use? And what ac adaptor you plugged into it.
I can think of a few things that are not what you think they are that have ac adapter sockets. But i cant think of a single Ethernet to usb adapter that takes 12v all the ones i know would be a 5v adapter at most with more running off usb power...
I would look for a replacement nexus player not just the ac adaptor... Check target or walmart first they dropped them down to 20-40 when they got discontinued i wish i had picked up a second one now... i got 2 of the game controllers one for 29 one for 10...

Yeah it is not the ac adapter. I tried an equivalent 12v 1.5amp and it still didn't turn on. When plugged in if I put my ear next to nexus player....I do hear a faint hissing sound, so there is some activity going on. I went out and bought a multi-meter and did what you suggested to check components tracing back to usb. This is all new stuff to me but I found that there was 0 reading on a tiny black rectangular module that has P15 on it. I'm assuming that is the smd fuse. Not even sure where to buy a replacement one. Tried to procure one from old computer board but was unsuccessful. Will search some more online on where to buy one and learn how to solder.
The ethernet I bought was http://www.ebay.com/itm/White-Micro...851881?hash=item567e4840e9:g:QEkAAOSwvt1WRYAO I wasn't thinking and plugged a 12v 1amp into it.
Only nexus player I see being sold is on ebay. I'm being persistent on reviving this one only because I spent alot of time on it already and am stubborn....lol But I will give up when I replace the P15 module and it still doesn't work. If nothing else at least I'm learning...so thank you.
Yes the little thing labled p15 is a fuse im about 80% i think p5 is also a fuse... you should get 0 resistance on them and they should be able to pass current switch the meter to Continuity mode and if the 2 probes are connected it should make a noise put them on either side of the fuses if they dont pass current they are likely blown as for replacements dangerous method would be to replace them with a wire otherwise they should be around .50 cents each from what i could find they are self resetting type so they should reset once any residual voltage is gone.
