Micro HDMI ports need to just go away

I've been through 4 cables, and two xooms because of them. The first two cables just didnt work, and the third one a room mate tripped on and broke both the cable and the port on the xoom. Now last night I was watching tv on my xoom, and the casing for the cable just kinda fell apart. I tried fixing it by pushing it back together because I was at a friend's house and we were watching tosh.0, but it just made the contacts in the cable go all over the place. Now I'm afraid I may have busted this xoom too, because two of the contacts are stick out a little bit.

Sorry to hear about your bad luck. But I really like my HDMI cable for mine. But the only thing I dislike about it is that the sound out of my surround sound sucks.

yeah the sound quality can be iffy sometimes, that's on the xoom side though i think. Monoprice is replacing the cable again, I'm just super worried about the xoom. I bought it because of HDMI, it's a required feature for me.

I recall reading your horror story about your friend"s room mate tripping over your cable. Sorry for such bad luck. But these things are delicate.
Really the fact that the dock doesn't include the mini HDMI is pitiful, and your situation is a perfect illustration of why that oversight needs to be fixed.

I'm using the original Motorola cable, and have not had any problems. Saying it should "Just go away" makes no sense, as there is no alternative that'll fit in the case of the Xoom.

I mean these stupid delicate ports need to go away. How is it that I've dropped my phone with micro USB cables plugged into it multiple times and both the port and the cables are still fine?
Also, how much did the moto cable cost, and how long is it

It's $20 and about 4 inches I think.

4 feet? that...just seems useless, especially at 20 bucks. monoprice cables are USUALLY super high quality, i've been using their micro usb's forever with nothing like this happening. It's a 10 foot cable for 5 bucks, gold plated and all that.

I dunno. Two Xooms? And you've dropped your phone "multiple times"? Sounds like you might be a bit rough on this equipment.
No?

You've probably spent $20 on those 4 crappy cables. If you got the good cable to begin with, you wouldn't be in this situation. Cable has nothing to do with the port or how poorly you handle your devices.
Also, Micro USB != Micro HDMI

i purchased one, the others have been free replacements.
Not everyone can have their xoom in a forcefield with a mind control ui, so they never ever have to touch it or take it anywhere like you.
I'll also throw out there that my evo's hdmi port has been around longer and is still fine, so maybe it's just motorola that's screwing up.

Hi,first my English not good lol...now my question is i have a wifi xoom. And a Motorola Droid x HDMI cable,but when i try to see in TV i don't see anything what's wrong?

I'm assuming you're talking about the Droid X. The DX's hdmi out is only supported within specific apps. It won't just "mirror" your droids' screen onto a TV like the Xoom does.
Youtube and the like use it as long as the cable is plugged into it. There are apps on the market that will accomplish this though. It's a limitation in the Droid X's hardware somewhere that does not allow simultaneous images, so the apps will just put it on your TV screen, which makes touching icons a guessing game.

Really? You have broken it that many times and its not your fault? I find that hard to believe. Take care of your stuff!

MUFUKA YUU DUN KNO ME YU DUN NO WERE I CAM FRUM SHIIIIIIT.
No really though, I've got my genesis from my child hood, an immaculate dvd and blu-ray collection, my xoom has no scratches or anything on it, etc. I do take care of my stuff.

Hi all,
I have to say i really have no issues with the micro HDMI to HDMI cable at all but then i did buy the Motorola one which wasn't cheap but as usual you tend to get what you pay for in life. I connect mine straight to my monitors HDMI port and run Audio out from the monitor to my JBL powered sub woofer and 4 speakers i watch all my live and catch up TV and my downloaded US TV shows all in great quality and sound.
I also really don't get a lot of the complaints i see about the Xoom all over the place though as my screen is bright clear and sharp but then i have my screen brightness set to full and have Auto brightness disabled. I admit the one time i tried Auto brightness the screen was horrible so i just don't use it. I also don't see any lag or stutter but then i am using ADW EX as my launcher and with the Widgets and apps i use have everything i need on just one screen and for me the Xoom is working perfectly. I actually bought my Xoom as my desktop went nuts and i needed something quickly and for what i need it for the Xoom has totally replaced my desktop sure I'd like to see Moto give us Euro users updates faster and enable the SD card but for now i can afford to wait.

... or it could be that yes, you're just clumsy. I fly at least twice a week and my Xoom goes everywhere- the office, the home, the hotel (hell, it's with me in Mexico now) and I'm just not getting how you're managing to break the thing. When it's time to go I just toss it into my briefcase and go; no special handing necessary (except the gel case; perhaps you should get one?).

It's not my xoom that's breaking.
I got my fifth replacement cable in the mail yesterday and the port on the xoom is fine. however, like two other cables ive had, the micro hdmi end on it is flimsy and loses connection.
My first xoom broke because a friend's room mate tripped on the cable, ripping it on the xoom, and busting the port on it that way.
This is my second xoom, and my first one was faulty anyway in that it randomly rebooted and the charging light couldnt turn green.

Got a Transformer today - impressions on defects

Hi,
I just received my Asus Transformer (32GB) today. Thought I'd give my thoughts on the defects that have been mentioned on the forum.
I'm really happy with my Transformer. The light bleed is minimal. At 100% brightness, I can see the lower left and the two spots along the bottom, but it's really not that distracting. I don't' notice it in dark scenes in movies.
No speaker issues - good balance, no pop (yet).
I started charging (and using at the same time) at 30%, and it took about two hours to charge to 100%. Charger does get pretty hot.
I updated to v3.1. But the little bit of playing I did before that was fine. Pretty responsive screen. Note, other people seem to indicate the default desktop is the active one with the glass? Mine came with a tree/hill static desktop.
Build Number: HMJ37.US_epad-8.4.4.5-20110527
I don't know if that's a software build or a hardware build on May 27, 2011?
Wi-fi is fast (1.3 mBps on one download). GPS and compass works great. MicroSD card works good. Plays movies OK, but I don't have any HD movies yet...play 350MB / 50 minute AVI's fine.
Slight plastic squeek on the left back side between the back and the bezel. No biggie.
Video capture from the back camera (5MP) better than I thought. I saw reviews where there were a lot of artifacts and skipping. No issues with this build.
Overall, really snappy! Only hiccup was at some point (after the 3.1 update, after I had installed and played a few games), I flipped the tablet around and the screen turn into the black screen with the Asus logo in the middle. Couldn't get it to go away until I push the power button. Touch screen didn't do anything. Who knows.

Every piece of technology has is glitches, some are minor while others can be maddening. Especially when you're on the cutting edge. Overall the TF is a very good product and I'm certain Asus will fix what it can. I've been a corporate buyer of Asus products since the early '90s and have always trusted their products.

Well said.
Everyone is new to honeycomb and the hardware platform. One thing I have really started to understand is that there is no perfect device - everything has it's good and bad points. I'm am very happy with the TF overall because for my useage the good far outweighs the bad.

I don't really know when mine came off the manufacturing line. But, if mine is the latest off the line, maybe they're starting to work out the quality bugs? I hope.

Same here. This is actually my second Transformer. The first one I got from Best Buy had a vertical line on panel 3/4 that would show up pretty often. Tried to return it to them for a replacement but they were out of stock (of course). Then I bought my second one at Newegg and returned the first. Second one has no defects. Screen, cameras, speakers all good. No light bleed. I get a little creak in the right bottom corner but that is only when picking it up one handed. I imagine that puts a little stress on the case considering the weight of the device and I probably shouldn't do so

My personal experience with the Transformer has been generally great, especially given the price they ask for it.
But, Honeycomb in all honesty leaves a lot to be desired.
It never made the best impression on me when I bought my Transformer, but this week I picked up a Samsung Galaxy S2 and using Android 2.3 on a new high-end phone has really highlighted for me how much room for improvement there is for Honeycomb.
Honeycomb looks pretty and has a well thought out layout, but the stability and usability need improvement. Sadly with ICS on the way we'll probably have to wait until the end of the year to have a tablet-optimized Android that works anywhere as well as Android does on phones.

Im also on my second one after getting it replaced due to light bleed... no big deal.
If only.... there had been plenty of stock when released, there were no light bleed issues, speaker balance, buggy o/s it would be perfect.
But I still think its better then an ipad due to the freedom it gives in customization.
And I love streaming movies using upnp on my home wifi from nas perfectly

Same here. Minimun light bleed, some speaker unbalance, but no cracking nor any other thing.
Mine came stock with the tree wallpaper, and I have the water and ice also avaible.
Pretty happy with it.

I'm on my third one.a little crack on the lefthand since but other than that it's fine. Been reading a comparison on the Samsung GT 10.1 forum and everybody says that GT10.1 is much better. Why? Because it has a flash? And no microsd

Malandro, how are you streaming movies? I have an Asus router w/ USB port running tomato, and I can connect a USB HD to it for the UPNP. But, when I try playing large avi's, it tries to download the whole thing before playing it, so I haven't played any movies on it, figure it wasn't capable of streaming?
edit: what movie app are you using? Also, what does your network look like? Router w/ USB external HD also? Can you stream off of windows shares (SMB) files?

As for my personal experience, no big complaints here but I think the creak on the left side is unacceptable for a device costing 400€, and one that for me highlights the lack of quality control in the manufacturing stage...
Other than that this is a fine device but Honeycomb still has to evolve as a platform, and I wished developers would see the vast android user market as one to take advantage of.
i.e. Simultaneous releases on both iOS and Android would be nice

Interesting. I haven't come across that idea in the forums before. Basically, if the power strip was a face, you're putting the Asus tatoo on the forehead of the face
I'm charging mine now right side up, so we'll see. I forget which orientation I had it in last time.

The main problem with upside down charger is the polarity. Some have reported minor shocks. I say minor because it charges at what 15 volts? I am an electrician and used to shocks so that much is hardly negligible to me, more of an annoyance. I think to get a decent one 24 volts or more would be necessary but that does depend on circumstance and other factors. Everyone's sensitivity to shock is different. Best to keep it plugged in correctly.
Bought mine from BB about a month ago. If there's light bleed I'd have to be in a completely dark room with a dark screen to tell. Seems like a good build. No speaker problems except total volume is low. No creaks. No screen separation. 3.1 honeycomb?.... it and the programs written for it still need some work. The new Sammy looked nice at the store. Nice enough to take mine back and pay more for less features? No. I like my TF. I'm keeping mine. Got the dock on the way....

When your taking about download speeds why are you quoting '1.3 mBps' as bits everybody on the entire planet would think you're talking about bytes. it 25 bytes = 209715200 bits, give or take a few pancakes
We have virgin broadband at home and work, if i run an ADSL cable from the router direct to my laptop (no interference) at work i can scrape 32 megabytes
I certainly wouldn't be able to do my job at 2.2 megabytes!

And also if it's backwards, the case gets a slight charge....if you touch it ever so lightly, you'll get a tingle.

So, if the power strip is with the holes up (like the eyes on a face) the usb plug on the charger would be on the downside? or on the upside?
I stream my content using upnp, from an external hdd plugged into a router via usb, with buzz player (Paid app).
EDIT: Plex server for windows (Free) + Plex for android (Paid) also work pretty good.

Looking for preorders / donations

Hello everyone, recently picked up an acer a500 over the weekend and i have to admit i am in love with it, i have always thought that tablets were useless when i have an android phone but i have to admit, this thing has changed my mind, and the fact that it has full usb makes it even better, but I have been a little annoyed at the lack of a keyboard / laptop dock. After reading a couple of threads about what the dock connector does on the tab I have decided to fill the need for this adapter. What i have planned includes the following.
Definite features are:
Full Keyboard
Charging ability
Extra usb ports
Possible features are:
Built in harddrive and OR memory card reader
Built in battery (obviously a little expensive to add so may be not possible)
Built in trackpad to use as a mouse.
I am just trying to see how many people would be interested in this and what they would be willing to pay for this. I would love to provide an adapter for the community since acer didn't make one, I also have a couple of other questions as well, if i made two models, one with a battery built in and one without how much more would you be willing to pay for an extra battery, also this would be a fordable dock meaning you could fold it together to carry like a normal laptop.
I look forward to hearing some responses, i hope to be able to offer this for about $100 or less however the more features obviously the more expensive it will be to implement.

if its possible, i'd love to buy one!

Awesome, I plan to have a prototype made by the weekend, i think the material of choice is going to be wood since it's light weight, easy to manipulate and also sturdy and it doesn't conduct electricity

once i see a working prototype, then id preorder, until then all your doing is fishing for donations, ive been lurking xda for quite some time and usually people with so few post and not a recognized developer are just spewing flights of fancy and never actually create anything, though if im wrong, prove me wrong and ill be the first to not only apologize but preorder one. not trying to be a d*ck just saying how it usually goes..

If it looks good and works ill be instrested

Using my volt meter and some old fashion trial and error, I'm pretty confident in my abilities just need to actually get started on development, going today to look into what my supplies are going to cost.

A voltmeter isn't anywhere near enough... You might want to check out this thread first.

I know I will need more than a voltmeter, and yes i read that before i decided to embark on this project. This is where trial and error will come in, from a usb standpoint since there is an apparent lack of usb support through the dock this will be circumvented by having a small plugin to the usb host port in order to connect the planned additional usb devices in the dock.

genius
This is fantastic! I've been searching for a good case too, this sounds perfect, give the Transformer a run for its money. I'd buy one, let me know.

The dock connector doesn't have the required pins for USB, or really anything other than charging.

any prototypes up? the idea of the keyboard dock extra battery and usb mouse sounds like bliss

It could be some sort of variation of the keyboard that Acer already made for this tablet. Perhaps modifying it so that you can put the dock in to charge and have the input device (in this case the keyboard) connect via bluetooth. Having the touchpad for a mouse is a different story though.

Be cautions with Trial and error on a mobile device . there electronics will not be forgiving any type of over voltage or short circuits . And you could very well be shopping for a new ICONIA .
To me a dock for a hand held tablet is counter productive . PEOPLE BUY A NETBOOK.its faster more power more storage more battery . LESS MONEY.
Ok the above is my opinion only I have a 11.6 inch hp notebook with the new multi core amd fusion cpu i get unbelievable battery life. Near that of my iconia .
with a full keyboard and track pad 1.2 tb hard drive
So good luck . by the way if you get the connectors and hardware worked out make the case out of lexon or carbon fiber both easy to work with and mold to any shape . acrylic works well also..

Acer has not made a keyboard that uses the dock for this tablet. You may be thinking of the W500 keyboard, or of a USB keyboard.
To be honest, I don't see this going anywhere. OP, I'd suggest you find out how to get USB or Keyboard off of that connector before asking for preorders.
To anyone else, I'd suggest you just keep looking. Not to be rude or mean to him, but the OP seems to be rather noobish, and I think your money would most likely be better spent elsewhere, or at least held onto until there's some sort of result or breakthrough.
Also, the OP only having 9 posts throws up a red flag to me.

Using nexus 4 internals go make another device?

I have a nexus 4 with a smashed screen and back. I bought another one.
The all the internal stuff is fine. How would I go about taking the logic board etc... and make something useful out of it?
For example. Would it be possible to take apart mu Kindle fire and replace its innards with those from the nexus 4? This is probably a bad example but you catch my drift

No and yes. First of all, you'll need a pencil solder and a device that you can loose without crying
Most of the electrical components are made for a specific device. You can't just replace components from other devices. Trust me, I have tried this, and nearly set my house to fire when I tried replacing the transistors on my amplifier with others....

yeah i figured most stuff is set to work with certain components. Is there any where you, or anyone, could point me to do some research on this type of hardware modifications?

Well you can start by looking up the devices in question on pdadb.net. That site gives a lot of specifics about the hardware, so it's a good start at least.
Sent from my buttered S3

You would start by gathering information about the two displays, then engineering an adapter that would suit the power needs and put the signals to the right place. It's not an easy task.

Maybe it can be useful even without a screen.
Garage door opener, security camera, something that can find your car if its stolen.
Just be creative. And show us the results if you did something cool.
(Think of all the ways the device can communicate: WiFi, cellular, NFC, BT)

if only the screen broken, so u can buy a slimport mhl adaptor and keyboard. plug your phone on tv, so it becomes to a smart tv.
or best choice is to buy a lapdock. so plug the nexus4 with the slimport on the lapdock and u will get an android pc.

Difficult endeavor with a highly probably of cracking panel due to copious use of industrial glue. Bigger challenge is finding a viable battery as replacements have not been manufactured for years. Anything tagged as 'new' likely has been on the shelf for 5+ years or recovered from another device. Li-Ion batteries have a shelf life; deterioration begins almost immediately. Google for details - Battery University is a good site.
tl;dr - don't bother unless the device has little to no value in its current state.

Good insight. Thank you for the feedback. I'll have to think about finding a replacement for this tablet soon. I would prefer one that has reasonable easy root capability and custom ROM support. Any suggestions?
I would definitely prefer a faster tablet experience and better sound.

Given the criteria you're probably into a niche device costing hundreds of USD. No immediate suggestions as I use other gizmos for more demanding tasks. You might find satisfaction with the latest HD 10; definitely a step back from a HDX but is seeing active development which may yield enough benefit to justify a switch. Alternatively, consider a permanent tether with a long, flexible USB cable and, perhaps, a decent sized external battery.

Just an FYI to an old thread- the HDX 8.9 is not that difficult to take apart as the screen assembly is not glued onto the casing. You need to remove the black shiny strip (which is glued) to uncover some screws that hold the screen assembly in place. This page has details and a link to a Youtube disassembly video:
