[Q] Phone docking and the argument of convergence. Who has a dock, huh? - Ubuntu Touch Q&A, Help & Troubleshooting

The Ubuntu Touch OS is a pretty big topic as of late, and I'm really hyped to see it come along... but I have to say, I'm shocked by the lack of docks for a lot of devices lately.
Why do I say this? Well, I suppose it's less relevant to UbTouch, but it's pretty important and worth mentioning. More and more, these modern devices are coming out, offering crazy specs like Quad-HD displays and quad-core processors, but it's given a hardcore hardware limitation, usually defined by the USB port with the MHL/OTG nature. I don't know enough docks where a phone does it, but I know Samsung has that on lock. You look at their products, their USB port is designed well, able to plug into a dock that has an HDMI port, a micro-USB cable for syncing/charging/powering the dock, and a USB host port, for keyboards, mice, etc.
Samsung's devices, from a functional standpoint, seem perfect for UbTouch's offering of the convergence with the desktop functionality, but their specs don't fit it. The specs are catered to a simpler crowd, as Samsung's done for a while. The company's that DO offer the specs for it have skimped on things, or at least, they've not bothered to mention that they can do simultaneous display output with USB host functionality, because we haven't seen docks that have such things.
A few years ago, backing to the HTC Evo 3D and 4G LTE, that device offered a dock, or KiDiGi at least, with an HDMI output and a microUSB for powering the dock and charging. Custom ROMs make it possible to use USB host, amazingly, but I need to wonder where we are that we aren't seeing docks more.
I believe I can guess the answer: Miracast. That's right. The screen casting feature. They don't look to HDMI and docks with it because of the fact that, with a small plug-and-forget dongle or the like, you can just wirelessly cast your screen. You don't need a keyboard and mouse, no bluetooth and junk. You sync it, you send it, you use it, and that's that.
Because of this, and the fact that only Canonical, and the companies behind them, believe in this convergence right now, I can't say it's a surprise that no one's trying to bring on this expanded environment through their phones, with a dock that, having it set up, allows that convergence.
Maybe I'm missing something. Who's got a device and dock, and who's experimented with Ubuntu Touch, assuming it was ever part of the choice for your device? And is it a Samsung?

I've been using Ubuntu on my Nexus 4 since February. While you are right that there currently aren't too many devices which have pins for a dock, it would not bring any benefits to the Ubuntu Touch experience if there were, as Ubuntu hasn't reached convergence yet. Moreover, the work on Unity 8 for the desktop hasn't even started yet (besides their initial creation of a version of Ubuntu which runs Unity 8 and Mir but looks like the phone/tablet version). The work to create a desktop UI for Unity 8 will start after the release of 14.10. Let's see when we will get full convergence.
(What is, however, already converged are apps. You can already install the Ubuntu core apps on your Ubuntu desktop.)

I have no dock, but I still use an S3 i9300, will be upgrading to an Xperia Z3 sometime this year, but I don't' think the Sony dock is anymore than a charging stand, which seems to be an utter waste to me.

Docks are mostly useless for current phones. With Ubuntu we hope to change that.

A 'dock' is as simple as a usb cable while charging or even a link though bluetooth/wifi.
Personally I am looking forward to linux based ability on a phone.

Neck strap hole, miniUSB irDA, extUSB-USB cable

I'm looking for a good way to connect my neck-strap to my phone preferably to the bottom. Currently It's connected to the thing mounted on my hard-case that is used to support the belt-clip. This is not convenient as the phone hangs from the center. I've solved this temporarily by using double adhesive tape between the hard-case and the neck strap but it keeps coming off after awhile.
The trend of skipping irDA on current devices is sad as I use it for my TV, 2 receivers and 360. I have my X50v with noviiRemote but unfortunately it locks up frequently. The device is really old and I think It's giving up. New batteries don't help. I've been thinking of connecting a small irDA dongle to the extUSB connector prefferably by using a shortextUSB->full size female type A USB cable. The alternative would be to buy an Ipaq 211 and a Ultramote CF card. The 21x series seems to be getting full Linux support soon (http://www.handhelds.org/moin/moin.cgi/HpIpaq214). Seems like the biggest problem is PCMCIA and WIFI.
At last, the extUSB->TypeA USB cable is great and I wonder if It's available somewhere? All I can find is miniUSB->TypeA USB.
Re: Ir:
I tried that route a few years ago with a PocketPC and found that the device is too expensive and too capable to use it as a remote and the Ir hardware is pretty weak, as it is not really designed for that kind of use. I have been using JP1 remotes for about 5 years and I am very happy to say that for about $20 in startup costs and a fairly small and interesting investment in the larning curve, I have had $15-$30 several remotes controlling all my AV hardware - and on occasion any other stray Ir-equipped device, such as my camera for taking high-zoom long distance shots, where I could not afford the shake from pressing the button. I have kids, that really tend to abuse the remotes, so I have had to replace them a couple of times - no worries, just re-program the new one and go, since they are so cheap.
JP1 framework can support just about any IR controlled device, map any/many functions to any buttons, control different devices at the same time, do macros, support remotes with LCD displays, etc.
Wikipedia article on JP1 has good links to get you started.

I couldn't find any stores/sellers on eBay that have extUSB cables. miniUSB works fine and I'd rather carry one sync cable than two if both devices use the same port.
Thanks for answering

I have had no problems with the range on my X50v, however I'm sitting 2m from the equipment. If range is a problem I can add the Ultramote extender. The only dedicated remote that seems to fit my needs is the Harmony 1000 but it costs around the same as the Ipaq 211 and lacks bluetooth (in case someone figures out how to control the PS3 with Android, Familiar or WIndows mobile) and a whole bunch of other things (for ex wifi to control computer). I have upgraded the X50v firmware and I hope it will solve the lockup issues. It's slower now though. The 211 lacks IR and there is no info on the Ultramote site about newer devices without IR but I'm pretty sure it can be sorted out.

I have read some reports that using miniUSB in an extUSB outlet can damage the outlet. During the Kaiser days, using the miniUSB cable inserted didn't feel right. It feels very loose. Also inserting miniUSB into my my G1 seems to require some violence to be honest.

[Q] tablet as car head unit

Is there a way to use the hdmi out cable and hook it up to 2 car tv's (via splitter or something) while still having the video out put on the tablet itself? Pretty much want the exact same thing showing on all 3 displays. Though I'll be honest I know NOTHING about hdmi, the youtube vids I saw shows that the device will have video controls on it and only output the vid to only the tv.
If it matters the tablet I think I will be putting in there is the asus eee pad, but still 2-3 months to go so that might change before then.
Any one has even an idea?
XDA is not really the forum for it, but here's my thoughts on this (I'm also interested in something like this):
You can use any tablet with HDMI out and support for mirroring (I think most of them support it), and use a HDMI splitter like the StarTech 2 port HDMI splitter/amp to get the same picture on two other monitors. Should work great...
see and or search MP3 car on Google....
The site and forum and store offer "car PC" solutions to rediculously outdated crap every manufacturer is spewing as new fancy and high-tech.
you will be able to sync/link/whatever you like via some of their stuff... but possibly waaay more complicated than you are willing to tackle...
The suuuper fancy stuff in even the most expensive and high end cars these days is a joke by comparison to our phones... don't. Think they are even trying to offer anything smart or cool....I'm surprised Ford isn't selling a FAX machine as a "high tech" option

Why do Sony do this?

I have a house full of Sony products, I like the brand and build quality very much, but, with the Sony tablet, I cannot undersatnd why, they choose a 'special' impossibe to obtain plug, also, a charging voltage of 10.2v!
The internal battery inside the tablet is a standard 5v type, as are the workings I believe, so, it would very possible for them, to allow charging via micro USB at a standard +5v, as a lot of other tablets do.
The charger is £29+ to buy, nothing special, if I could get the plug, I'd knock one up for couple of £.
I also have a high end Sony 3D televison, that has facility for internet via USB, but, you can't use a standard USB wireless dongle unit, it has to be Sony, as they installed some data in the USB stick to stop you using cheaper USB dongles..... why?
Further, my Sony MP3 player NWZX1060, will not accept charge via any other, but Sony 5v power supply, the Sony ones are of course 5 times the price!
Don't get me wrong, I love Sony gear, but, feel slightly annoyed the way they do things, even more so with the Sony Tablet.
Anyone else with simialr feelings?

I agree that Sony's plug selection was ludicrous; however, because most USB ports on computers and chargers cannot supply the 2.9 ampere charging current that the tablet requires, I believe Sony purposely selected to use a non-standard connector to help prevent their customers from damaging their computers, etc. And Sony using 10.5 VDC instead of 5 VDC decreases charging time (similar to the difference between quick-charge and trickle-charge of an automobile battery charger).
I understand exactly what your saying, but, surly for sheer convenience, Sony could has incorparated a slow(er) charging facility from standard 5v supply, using computer USB or different lower current charger, most other portable devices allow this.
I love Sony stuff, but, they always seem to do things differently, nothing wrong with that of course, until it cost your more, sometimes unnessacery money! ..... maybe!

You know, I've heard this a lot, but I bought some nameless brand USB adapter plug on Amazon and it works just fine. Maybe I got lucky.
As for the power adapter, I always assumed it was a special port to accommodate their cradle and keep other tablets from taking advantage of it. Seeing as I don't care about the cradle and would love to charge this thing in a car, it's still awfully inconvenient.

Sorry, but this is wrong! You shouldn't buy the cheapest China Crap charger but your x1060 works with non Sony chargers, too. I had a x1060 and it cod be charged through my Usb-chargers from Palm, Belkin, Blackberry etc. without problems!
On the rest you are right... but most companies do this!

So far I've connected a keyboard, mouse, logitech usb gaming controller, and synced my PS3 controller with this adapter. I'm on stock ICS.
Sorry for the late reply. Just got a new phone and haven't made it back around to this part of the forums yet
Feel like Ive been treated as a crash test dummy.
Wish I'de never bought this tablet, the main reason is the charging problem, I spend most of my life on the road with no respite until I get home in the evening and no access to the 240v needed for charging, with the occasional foray into work related periods during which time my tablet is important, so many times have i had to rely on paper and pencil until I got home because the tablet was dead, which defeats the whole idea of mobility.
And dont tell me about the tablet needs a certain amperage or voltage or charging time etc., other tablets manage without the stupid tethering to a socket and as for the ics fiasco for Uk users, what can I say.
As a product I like it, but its a bog standard operating system nothing to set it aside from the rest except its design, but the cons far outway the pros for me.
Mind you sony are not alone in there disregard for their user base, I started with HP ipaqs, until HP decide in there wisdom to stop supporting them, then there was the Dell streak episode (painful) Im still paying for a phone contract for a phone that I cant get repaired because the parts are no longer available, had about a years use out of it befor it broke, not good for a £400 + phone.
Im of an age that expects more out of my purchases than the shoddy service we get served up with by manufacturers that treat us with destain and use us as a beta testing ground with impunity when things go wrong.
Sorry about the rant, must have got out of the wrong side of the bed this morning, still its a thumbs down from me.

I disagree with you here (respectfully, of course).
Battery:
Although other tablets can be charged off USB, they have sacrifices as well. Tablets chargable by USB will be much slower to charge and (theoretically) have shorter long-term lifespans. Sony decided that the 240v-only charing was a worthy tradeoff for the quick charging time and long battery lifespan.
Software:
This software is actually quite distinct from most other HC/ICS tablets. It is thankfully spared from the mess that is TouchWiz UX, and instead gets useful additions like Small Apps, the Favourites launcher, the three-icon dock, and heavily customised and highly versatile stock app inclusions. Although I like Acer's wheel launcher, the Sony is the best all-round software package I've seen from an Android tablet since my original Galaxy Tab.
Support lifespan:
I feel for you on this one as a previous owner of an original Galaxy Tab, the disregard for older devices is disheartening, but is to be expected in any dynamically developing field such as Android Tablets. It is simply not economical for companies to maintain full support for product lines that have been superseded, are getting old or simply don't have the users. It doesn't make business sense. In their defense, Sony support have been fantastic in my limited experience.
"Beta" nature:
It's unfortunately the nature of cutting-edge products that there will be unexpected quirks, but you should factor this into the buying decision. Long-established lines like Samsung's Galaxy Tab's are an obvious example of better-known, and more refined tablets. As an iPaq owner, you should remember that the original ipaq's were very quirky, buggy and generally lacking in refinement at the expense of their great functionality. The same is to be expected of this product, which you must remember is Sony's first foray into the Android Tablet market.
Anyway, sorry for the even longer rant, but I simply love my Tablet S and find that many users are maintaining some unreasonable expectations for this product and generally not thinking before they're buying in some cases.
I agree with most of what you've said, but as a comsumer with no loyalty or affiliations to any one product I simply want what is best for me, and you know as well as I, that when you buy a product such as this, it is mainly bare bones for a while until the industry gets it act together and things like car chargers etc come along, and that is what I expected, I did'nt realise until much later that you couldnt charge through the usb port in fact there are still items being sold on ebay under the term Tablet S charger which appear to be just a standard usb lead.
I originally bought a Ipod 1, which I returned to the store because the salesman assured me that it would play flash vids which in fact it would not, (some problem with Adobe apparently, fixed now I believe in Ipod 2.) and the Tablet S was the next thing to be recomended and with the dearth of info on the net at that time, I didnt have much option.
As for software, the first thing most of us here on this forum do is to root, then rip out all the stock apps and Bloatware and replace with different UIs etc.
Support seems to be shoddy in the extreme (and I dont nesseccarily mean Sony here), but most like you (respectivly) seem to accept it, personaly I hate it, but I seem to be in the minortity, I would dearly love to go round to some of these companies with pitchforks and burning firebrands (joke, in case anyone takes me seriously), would you accept the same thing if it were a car you were buying or a house, just because a thing is only current today doesnt mean it should not be fit for purpose, it should have a life span of more than two weeks.
Economically viable, Ha, have a look at Sony share prices or any of the market leaders come to that.
I simply dont factor in quirks or anomallies into my buying decisions because I as a paying full price consumer, expect things to be fit for purpose, and, i reiterate, with a resonable life span, how can it be right that something you pay good money for be entirely unusable in the space of a few months.
Thats all I'll say on the matter, please dont regard this as a flame because it isnt meant as such, and im sure I must be breaking some forum rules ranting on, my appoligies if thats so.
I can see what you're saying.
This is not specifically about you, more other users, is that everyone needs to remember to research before buying a product. In your case, a quick Google Search would reveal that no iOS products are capable of playing Flash content and never have been. WP7 is the same while Android can play it after installation. The same goes for the Tablet S in that anyone who posts about no hardware video out, a lack of custom ROM support, or simply the smaller screen size has obviously not done much research about what they're buying. Different devices have been designed for different purposes, and people are expected therefore to buy the right tool for the job.
As for Sony themselves, remember that this is their very first Android tablet and is a very small part of their business. Their tablet division, which hasn't sold amazing numbers, would be being helped along in terms of share price and revenue by Sony's other businesses including the highly successful BluRay, DLNA licensing, PlayStation, XPeria, Walkman, Sony Pictures, Sony Music BMG, CyberShot, and BRAVIA units. Compared to those, the Tablet S is a minor blip in the radar.
Although to me your expectations seem high, and references to two-week lifespans seem odd, thats obviously your opinion and you're entitled to it. Just trying to give any readers a clear picture of what to expect.
.... Some very interesting replies in this thread, most, of which I agree with.
Sony, is now a massive company, huge, so, surly, theR & D departments would have given an indication of what people actually wanted in a tablet?
Another thing about Sony is, they seem to lock their (modofied Android) firmware down, such as the Sony Xperia S I bought a couple of months ago, this I discoverd some time later, has a locked bootloader, so, I can't put another (better?) firmware, I think it's simlar to the Sony S tablet?
Some people will say, it's to stop you messing and spoilng things?? if a person wants to change firmware etc., surly it's up to them, if they mess up, it's their fault, and, if neccessary, should pay to have it rectified (by Sony?)
I love Sony stuff, I have a house full of it, but, when you want to expand, use non Sony gear with it, change or, deviate from the norm, there is usually always a problem.
Is this all in Sony's interest to generate even more cash ......... I wonder?
Just my thoughts.
Although cash is a bit of the process, its more to do with Sony's hardware and software philosophy. All of Sony's devices from the Xperia's to the Tablet's to the PlayStations rely on Sony's design which uses locked down software models to ensure that the device works as Sony designed it. They basically believe that a tradeoff in user customisation is worth the more polished experience. This does unfortunately mean that early products in a line (think early Ericsson-partnered Xperia's and the Tablet S) sometimes mess up the balance a little.
Sony, as a brand, often invests in its own proprietary formats, software and designs, and therefore tends to lock them down more than their more open brethren at other brands like Asus.
I agree with you about their R&D and I find it odd that in some respects they nailed it (I love that glorious curved design), but in other respects buggered it (battery,software tweaks). Meh, who knows??
imho opinion the S is the best non-ipad tablet out there. If you think Sony lock the system down and control how you use the device you haven't experienced Apple products.
I'm happy with the S. The remote control, native DNLA and Flash support are the 3 things that sold it to me. Now upgraded to ICS It's not rooted and I can;t see a need to root it.
sure I;d like a better screen and a faster machine but who wouldn't.
Hi ...
I echo what you, and the previous 'senior member' said, I too have no reason to root the Sony Tablet S, yes, it's a lovely machine, that's why I bought it, mine was the same price as the iPAd, but, I choose Sony, as, I'm sure lots of other people did too.
My gripe was directed at the Sony Xperia S mobile too, that firmware is locked down firmly too, and, being a fully qualifed electronics engineer, I cannot understand, why, the Sony S tablet, has a UK charger of 10.2v at 2.9A.
It would have been a great help, if a slow (emergency?) charge facility was available via the micro USB socket at 5 volts, although, your limited to 500mA on USB 2... more people now have USB3 which allows much higher charging current, so, in my opinon it's very possible.
Or, maybe 2 x USB leads, as on the Sony portable CD reader/writer, that uses 2 x USB plugs to deliver the extra current required.
The internal battery inside the Sony S tablet is actually 5 volts, so, it seems quite possible in theory, to allow a lower current charge at 5 volts, although will take a lot longer to charge up fully of course, maybe up to 10 times as long? ... B U T , it might just get some people out of a mess?
Also, the wierd plug Sony use for the Tablet DC power supply charger, if I could get a plug itself, I could build my own car charger, an easy task.... a 'standard' DC socket arrangement, would have been better, some tablets use this type already, they could even incorparate that into the dedicated Sony Cradle.
Just my opinion, Sony do things in strange ways ........
What does anyone else think?
I totally agree that Sony does some strange stuff sometimes.
Still love the innovation that Sony brings to their products.
Sony has a long history of doing things that make their consumers feel like they have gotten the finger. The company spent more see development time on the PSP blocking hacks rather than adding the features those hacks were being used to create. The same energy initially went into their music sales; anyone else remember the rootkits that came with their disks at one time? All of the proprietary things mentioned above fall into this category too.
That said, this tablet is yet another in a long line of successful products in terms of usability, ingenuity, and quality from the company. I have rooted, but for the most part Sony's product works well on its own. I'm overjoyed with the USB conversion dongle, and the tablet is nice to hold.
It's unfortunate that the company has so many low lights in its dealings with customers, but it's not like we should be surprised. Personally, i bought this tablet when i saw this board and knew that it would be another Sony product with side development for the dumb bugs. Now if i could just get plants vs zombies to work...

The 1 thing I think the dock is missing...

Is a blue tooth module so you could hook your prime up to the tv and take the dock for typing to the couch and so forth. Having a long ass HDMI cable dangling from the prime is kind of impractical for couch surfing.
Considering the prime's BT issues even that could be a problem lol.
You could buy a bluetooth keyboard with some form of mouse input built in. I have this, which I can't find anywhere anymore, but there looks to be a smaller version here that might do the trick.
There are apps you load so you can control your prime from your Android phone. Like a remote..
I already have a diNovo Edge, great keyboard. I just thought it would make the dock even that much more functional instead of going out and buying another accessory.
Thanks for the app tip and keyboard link. :good:
I'd rather have USB 3.0 as another slot altogether. they could have done it and I would have paid extra for it
I voted to raise the thread star level.
I agree with the Bluetooth for the keyboard cause having a 12' HDMI cable going from my tv to my lap is a bit of a tripping hazard. Also I agree with the addition of a second USB port that is USB 3.0 so data could be transferred faster.
I bet we will see all of these added to the next tablet released by Asus, if not Apple or Microsoft will jump on it and give customers what they are asking for.

Seems that the old MHL HDMI adapters don't work for SIII?

I had one of the 10$ ones from ebay that worked perfect with my galaxy nexus, but when plugged to the S3 it just charges, no output to the TV.
I heard that they've chaged something for the new one, but wanted to confirm and make sure there is no way to make the old one work?
That's pretty unfair move from their side, forcing people to buy new accessories with every new phone...
m?
They upgraded the technology to bypass some disadvantages.
Compared to the old one
- you no longer need an external power source for the MHL adapter
- you can use USB-OTG and MHL together (e.g. playing a video or presentation from your USB-Stick on the television/beamer)
Yes it sucks, but progress in tech always breaks backwards compatibility or at least makes it a lot more complicated.
In this case, no compatibility is known to exist.
I see
those are good advantages and actually I like it, if that's the case
Now are there any adapter that are less than 30$ available, or we are still stuck to the original ones?
