[Q] OTG, what for ?

Hello,
I bought an adapter to attach USB devices to the Experia, but what ever I tried yet, it says "incompatible"
So what´s the use of it ? I thought I could attach some memory sticks ?
Cheers

Are you using the default kerenl? It does have USB OTG but the device drivers are pretty less..
You might want to try Doom Lord's modules here,
http://forum.xda-developers.com/showthread.php?t=1224676

Yep, default kernel.
Ok, I will give a try. Thanks.

Will work on stock after the next upgrade.. Due next month, hopefully!

Yes, recent firmware 4.0.1.A.283 natively supports usb otg feature.
Just buy a usb otg adapter(search 'otg' at dealextreme.com, for example), and you can use your mouse and keyboard with your phone.
But I think it doesn't allow users changing its input method, which means it can accept English only :-(
Is there anybody who found out how to change this behavior?

ics does not see usb

Hey everyone
I have the sprint galaxy s2 , stock ics rom (rooted)
this unit does not see the usb, (no otg), there is no window telling me a usb device is hooked up, the thumb drive does not power, and the usb host diagnostics says my device does not support usb
I installed stick mount just to be sure and there is no device seen
anyone have any ideas how to enable this, am I missing a file somehow, or possibly a link to a stable ics that does support otg
any help is appreciated and thanks in advance

Right now from the looks of it, self powered OTG is nonexistent on the epic touch. There might be a chance that OTG through a powered hub or USB Y cable might be possible. But standalone? Not a chance.

thanks for the response but my galaxy doesn't see powered usb devices either...I think I am missing a file or need to enable something as others have what I am looking for
ps, this youtube looks like e has usb otg self powered
http://www.youtube.com/watch?v=giJXF5pIITc
according to the posts on that tube, some users can do it some can't, it looks like sprint cannot...something is missing in their rom I suppose

I am now led to believe it's more likely a hardware issue rather then kernel, I think if it were a kernel problem simply flashing to a kernel that worked would do the trick and porting it over would simply be the same thing as porting say a verizon ics over to sprint
nobody can get otg working on a sprint epic touch regardless of kernel.
so sad, I traded up from 3d otg for my torque program, now I see if I kept my 3d and installed ics I'd be gold

[REQUEST] Port PS3 Dualshock Controller from Xperia Tablet Z

Just wondering if there is a port of the official PS3 controller app for CM10.1 or EMD2.
I have found a port for the Xperia Z
http://forum.xda-developers.com/showthread.php?t=2244894
I would have a go myself but don't know where to start lol

Why do you need this? The SGS3 already, NATIVELY, supports the PS3 controller.

Ahhh right I didn't know that lol. Delete this post if not needed
Cheers bro

It works pretty damn well, too. You just plug and go... Though some games don't support it (a lot do) You can use some software to help map the buttons... but I don't do any of that so I can't direct you in the right direction.
I know this: http://buy.thegameklip.com/ is pretty awesome, though.

[Xperia Acro S] Encryption, Noob question please.

Hi guys. This is the right place for my question probably, with lot of enthusiast and talented developers. I'll try with other forums but no luck. Google too every search going here, so. My question is I like stock ROM of my Xperia Acro S, I like photography. I use my phone as a main camera. What is the best for me to gain maximum from my phone? I heard about Cybershot something, is it good? This is subquestion actually
My main and most important question Is about encryption (security). We know that Xperia Acro s does not have integrated encryption, right?
What is my solution, I like stock and stability without too much bugs, I have ROOT on my phone. Need encryption for phone and SD card. What you suggest? Thanks in advance...

Forget about it. Google won't allow full device encryption. Just wait for a custom rom for unlocked bootloaders to implement the same. Linux has it, so there is no technical reason for Android not to have it. In the mean time, use encryption per application. Get textsecure as your main sms application. Get gibberbot for messaging. Get K9 mail for e-mail. You can use luks manager which allows you to create file/containers where you can store data. Luks is the best, because it uses on the fly encryption.

[Qs] Prospective xperia pro buyer's list of questions

hi folks!
i'm looking to buy an xperia pro and i've got a bunch of questions about that.
basically i want to use the phone as my portable internet-gateway (usb tethering with my notebook) and portable media player for when i dont want to/cant carry the laptop with me. i also want a hardware keyboard since it makes writing texts and surfing the web on the road that much more enjoyable.
i will flash a custom firmware and tinker as much with the software side as needed.
- i'm coming from the motorola milestone - maybe someone else has made that change and has some insights to share?
- would you still buy this device or get/wait for another phone with hardware keyboard and hdmi?
- are there currently any unresolved issues? any functions not working in the prominent custom roms?
- is there anything i should be on the lookout concerning getting root-access or unlocking the bootloader? some needed and specific hardware revision or firmware version of the phone maybe?
- if so - can this be overcome somehow (preferably also easily)?
- are there any issues with the data connection? ie are there power-drain issues after data usage? connection instabilities or interrupts (while stationary and with good cell coverage)?
- can i use an otg-cable to connect an external soundcard to upmix stereo-audio to a connected 5.1 system?
- can i use an otg-cable to connect an usb stick or external (powered) harddrive?
- if i can access external media - can i use the hdmi port to play movies from the phone on a connected hdmi device?
- if i can access external media - how about multichannel sound over hdmi?
- if i can access external media - is the phone fast enough to play 720p/1080p [using 3rd party apps]?
- can i connect to standard windows/samba (media) shares and play those without some special streaming protocol (like i can with a nas+wlan+vlc on a laptop)?
- there doesn't seem to be a dedicated forum to the pro - does this mean all custom firmwares will run on all the xperias?
- if so - will there be problems with the hardware-keyboard? ie it not being detected, some dead keys ...?
thanks for reading so long a text
edit: hopefully corrected bad formatting
edit2: marked fully answered questions

It is possible.

Click to expand...

Personally, I would wait, but do not get your hopes up, I am not sure, how popular are these phones nowadays.
It is actually quite an old device and Sony's support is very low on it.
- are there currently any unresolved issues? any functions not working in the prominent custom
roms?
Click to expand...
Click to collapse
As long as you stay on stock-based custom ROMs (GB and ICS only), you should not occur any issues (if the issues from stock ROM are fixed).
JB and all CM-based ROMs have issues, such as lack of HDMI connection....err there are more, I'm somewhat tired to write them all.
- is there anything i should be on the lookout concerning getting root-access or unlocking the
bootloader? some needed and specific hardware revision or firmware version of the phone maybe?

Root access can be acquired while on any ROM. However, the deal with the bootloader is a little more complicated.
All devices manufactured after 12W11 (11th week of 2012) have newer type of security, which completely disables test point method. All previously manufactured phones still have that possibility.
That leaves you with only the official bootloader unlocking method and that also only, if the phone has fastboot enabled (no SIM-lock, no branding). If fastboot is disabled...then you can not do much.
- are there any issues with the data connection? ie are there power-drain issues after data usage?
connection instabilities or interrupts (while stationary and with good cell coverage)?

I have used Xperia Arc and Live with Walkman, never had any issues with data connection. There is no power-drain issues, just a slightly increased battery usage, if data is on, but that is normal on all phones.
- can i use an otg-cable to connect an external soundcard to upmix stereo-audio to a connected 5.1
system?

Yes, Xperia Pro does have USB OTG possibility, you can connect a mouse, keyboard and external storages (HDD only via wall outlet or another USB power). These are confirmed to be working, however I do not know, if external soundcard would work.
- if i can access external media - can i use the hdmi port to play movies from the phone on a
connected hdmi device?
- if i can access external media - how about multichannel sound over hdmi?
- if i can access external media - is the phone fast enough to play 720p/1080p?
Click to expand...

Yes, HDMI port can be used to clone your phone's screen to a TV. That includes playing movies, games etc.
I believe there is multichannel sound, though I have not tested it myself. Phone can play 720p videos for sure, 1080p is unlikely, though may depend on the format (might require 3rd-party app).
- can i connect to standard windows/samba (media) shares and play those without some special
streaming protocol (like i can with a nas+wlan+vlc on a laptop)?

You can use DLNA, that works over WiFi.

Xperia Pro uses the same forum as Xperia Arc, so all Pro-related stuff you can find in this same section.
And no, custom firmwares will only work on the phones they are made for.
Also, Xperia Pro is not very popular phone, finding a custom ROM may be a little time-consuming, though I believe you can find a good one for yourself.
- if so - will there be problems with the hardware-keyboard? ie it not being detected, some dead
keys ...?

The hardware keyboard may cause problems by different keyboard layouts. Though to find more information, you might want to try searching in this Q&A section.

Thanks for taking the time to answer my many questions!
I'd like to follow up on some answers

I don't put stock in manufacturers anymore - communities will produce far superior results if given the chance. As far as I can see there is a wide selection of kernels and roms to choose from and still development going on. Am I mistaken about this?

I never perceived DRM to be more than a hindrance and stayed well away from any such tainted content...

1. Yes, the custom ROM community is still going strong. Go to the Android Development section and find a ROM of your choice.
2. Yes, since Sony did not release the required libraries for HDMI, it's not possible to use HDMI with a custom ROM for now.
3. The Pro is an old phone, if you want to find a phone that meets your criteria I suggest you get another phone.
4. You can use an online service like Wotanserver to remove the carrier lock for you. Official unlock method always works for any phone without carrier branding.

No major issues, that I know, so no need to be afraid of. Gingerbread build 4.0.2.A.0.62 is bug-free, never noticed a bug myself.

There are no factory-unlocked phones. Official unlock method will only work on phones, that do not have SIM-lock, no carrier branding and have fastboot enabled. Depending on which phone you will get, if you get one manufactured after 12W11, your options are limited.
It is not complicated, newcomers may have some problems with understanding, though I do not believe you should have any issues.
DRM, which stands for Digital Rights Management, is used for certain digital keys that allow paid content to be used.
Official unlock method removes DRM keys and by that, original TrackID will stop working (you can still use the one from Play Store), PC Companion will no longer update your phone, OTA updates will brick your phone (so just avoid them), Bravia Engine will no longer be working. The last one being most likely the only thing, that you might miss.

Just removing the carrier lock will not enable fastboot and will not allow official method.

HDMI usage is a hard requirement which seemingly means no custom roms for me. This is something i did not (and probably never would have) found out by reading through the custom rom threads. It might just mean i have to hope for another company's willingness to combine a decent hardware keyboard with android, hdmi out and fairly recent hardware.
Is this a sony thing or common with all vendors and phones?
I've looked over several rom and kernel changelogs and see lots of seemingly interesting things (many of which i don't even pretend to understand). While I can live without some performance and battery tweaks or additional governors and schedulers I probably would like to have overclocking and definitely usb-otg support.
Since the latter is often listed as a fairly recent addition to roms it's probably not even working on stock. But maybe i'm wrong in assuming this? Maybe its just about storage support while mice and keyboards work in the official rom?

You're right in that this is probably the 'worst' of the things you've listed. I found a decent article explaining what this actually does and I don't think I would mind terribly. For those interested here's the link:

HDMI on Xperia Pro
Hi,
I'm a newbie myself, but I just updated my Experia Pro with a custom ROM (Superlegger V6) and it _does_ support HDMI (I tested it out and it works fine).
My understanding is that any custom ROM based on Sony Firmware (GB or ICS) will support HDMI, but that those ROMs built from source (e.g. Cyanogenmod/Free Xperia, or any based on Jellybean sources) won't.

Yeah, I may have forgot to mention that stock based custom ROMs can still use HDMI.
Any JB ROM or non stock custom ROM will not support HDMI because Sony libs are not compatible with it.

However, your can use dnla.

Thank you for this!
Did you ever try to hook up an usb stick/hdd via USB OTG cable with this rom?
I don't understand the limitations of basing a custom rom upon an official one.
Does one need to keep the official kernel only but can exchange everything else? Or are relevant libraries/drivers extracted and used in conjunction with some modified ones on any kernel with the same version?

I have little experience with this technology - how well does it really work and how restricting is it concerning compatible media formats? Will it work on any compatible display/tv in the same way or will the functionality vary (eg a video on the phone plays on one tv while it will not on another)?
