:eek: Damn.. If you need to encrypt data on your phone's SD card you should probably re-think your security strategy and hide your sensitive information on a hard drive with TrueCrypt using their hidden partitions or something haha.

Phones are easily stolen and therefore not a good place for that stuff :p

But one semi-close idea/alternative to what you want, that you can also use now for the time being is available in at least the CyanogenMod CM6.1 roms(not sure about other roms seeing as I only repo sync his stuff :p).

Under 'CyanogenMod Settings' and then 'User Interface' there are screen lock options..

You can set the 'screen timeout delay' (determines the delay time after screen times out for when the lock will enable) to 30 minutes and the 'screen turned off delay' (how long after you press the power/end button the lock will enable) to instantly.

With it setup like that, you'll be able to greatly reduce the number of times you need to unlock your phone as long as you let it time out - which could be a slight downfall though if you have a screen time out of a minute or more and you don't want to keep the screen on. Regardless, whenever you want it locked simply turn the screen off manually and it will be engaged next time you turn the screen on.

Hope that works out until someone finds/develops an app that will do what you want/need :)
[Android Apps and Games] JeepFreak:
Thanks for the reply and the suggestion. I totally hear ya on that first part. I was mostly trying to think of useful features, not ones that I necessarily need. I wasn't sure if you could encrypt the data on the SD Card and then continue to use it (without a huge hit to the speed).

I wouldn't think my idea would be that hard to code (at least the basic structure of it). Maybe it's time for me to learn. 800+ views, but no dev input?

Thanks,

Billy
[Android Apps and Games] Insomaniac10:
ok, ive developed a makeshift idea, and id be willing to give this a shot myself:

first off, there is a free app called "lock screen widget", which will solve the problem of quick access to the lockscreen for people without a hardware "lock" button

next, maybe i could find a lockscreen app (it owuld have to be free, otherwise i wouldnt be able to post it in here, due to warez) and rip open the .apk and just make the framework allllll black.

a few things to keep in mind:

-you would have to memorize where to touch the screen to unlock your phone

-a cop could get lucky and swipe the right spot on the screen

-if you have LED backlit buttons on your phone, they could still light up when the screen is locked, indicating to the officer that the phone is in fact on

let me know what you guys think of this
[Android Apps and Games] jimbobalu:
How about just a swipe to lock? I too hate constantly unlocking my phone but if I could just lock it at the lock screen then this would most likely trigger the need for a warrant to access my phone by law enforcement.

Not that I am a criminal but I hate the idea that law enforcement can do whatever they want with your data if it is on your person.

Just a thought, could the swipe to silence the phone be redirected to lock it instead?
[HD7 General] stevew84:
I just picked up this phone and my thoughts are mediocre so far. But I have one issue that I cannot seem to fix. On my android, I would have the option on either Youtube.com, or the Youtube app, to choose to watch the video in HD. I dont see that option for my phone now, am i missing something? It sucks to have a 4.3" screen but with jumbled video.

Thanks.
[HD7 General] jimbonics:
The stock youtube app isn't that great. There is another one you can grab in the marketplace that is better.

As for watching it in a browser, it was likely omitted to avoid having to keep up with flash updates.
[HD7 General] stevew84:
But what about for HD viewing? I added a video to my phone that plays crystal clear...but i want to stream HD if the video specifies HD.
[HD7 General] humblehyper:
Did you download the YouTube app from HTC Hub? It can play HQ video.

Any idea where I can get the .apk?
[Nook Color Themes and Apps] colorado_al:
You should be able to go to Nook Color Tools and click choose keyboard to switch to the other keyboard. Not sure if that is the stock keyboard or not.

It's not there in Nook Color Tools. For me I just have the Multitouch Keyboard and Gingerbread Keyboard options. I too would like to get this keyboard back. Any help is appreciated.
[Hero CDMA Q&A, Help & Troubleshooting] da305kratos:
Hello guys,

Well I started not to long ago on this rooting, nand, flashing experience and thus far with your help here at xda its been great!

Recently started having an issue where I would do a nandroid backup and would get the dreaded md5 sum mismatch message when trying to restore it...

At one point I did change the name of one of the backups to which I read somewhere here is not a good idea, deleted that one and did a new backup...

I saw a theme for aosp which I flashed and well it didnt work (thats another story)...tried to restore a backup and again, same error..Had to flash a clean version of aosp 0.9.9.2...

Now the only change there has been to the device has been a new 8Gig MicroSDHC class 4 card from ADATA...Could this be the issue to the corrupt backups? Or is this a known issue with clockworkmod recovery(2.5.0.1)?

Any info on this would be helpful. I have the old card that came with the phone blank. What folders should I copy over from my new SD card to the old one in order to test to see if its the card?

Thanks in advance!
[Hero CDMA Q&A, Help & Troubleshooting] da305kratos:
simple answer would suffice to say the least...appreciate the help! :)
[Hero CDMA Q&A, Help & Troubleshooting] mrinehart93:
I would recommend testing a different card. It could be that the card is corrupting the files, therefore the MD5 checksums don't match.
[Hero CDMA Q&A, Help & Troubleshooting] da305kratos:
yea thats what i'm thinking...will give a try tomorrow and let people here know...dont want anyone else making the mistake on investing on a AData card for their Hero if its the case...

[HD2 Android Q&A, Help & Troubleshooting and Genera] paolo.dc:
Hi guys

I have followed (as much as possible) many threads on installing Android on the HD2 and finally succeded but got a few problems in doing so.

I upgraded the Radio first to 2.12.50.02.2 and then to 2.15.50.14 (the first one was better for me) and upgraded the ROM to 3.14.408.2 as released by HTC.

Now Android finally started but it was sluggish and not as responsive as WM. The worst part though was the power consumption that normally under WM used about 5% of battery for a 6 hours period during nightime while on standby with everything off except the phone but under Android used 60% of battery for a 2 hour period still with (I believe) everything off which is unacceptable.

I tried MDJ 4.4 and Core Droid 0.3 and both gave more or less the same results with the last one totally locking up the phone which did not want to come out of standby.

I am sure that I must have done something silly not realizing it but I have seen Android running on the HD2 of a person I met and boy was it going well.

Could it be the SD card with a problem or maybe the speed of the processor tweaked by a customization that I did not see or.......

Any help or suggestion will be welcome.

Thanks

Paolo
[HD2 Android Q&A, Help & Troubleshooting and Genera] DeoreDX:
First thing I would try is another SD card. I had one (Class 4 PNY) that would give me very high current draw numbers and Android ran very jerky from it (This was when I was running it from SD). Load times were easil 50%+ longer. Both my class 2's ran much smoother and no high current draw issues with identical builds of Android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Galactus:
had the same issue as OP. jumped onto MDJ's gingerbread nand (now cyanogen mod) and my battery has been lasting on average 15-16 hours with calls, text, internet browsing and music playing. in standby i lose about 1% an hour. at the time of writing my phone has been on for 19 hours & 18 mins
[HD2 Android Q&A, Help & Troubleshooting and Genera] buzz killington:
load up an app that tracks usage - spare parts or system panel lite for example, or just go to the settings -> about phone -> battery use. See what's using up all the cpu cycles or power. If something seems particularly high, find out why it's doing it and if you can't figure it out then use a task manager to kill it and see if your performance improves.

Anyone else having issues getting a GPS lock? I'm sitting inside a building but my Hero would always lock here, especially after resetting the AGPS data with GPS Status program. Tried that with the Shift, and still not getting a lock even after a minute. Not sure what else to try.
[EVO Shift 4G General] BrandoKC:
Typically I keep mine turned off, but I just turned mine on and went to Maps and it locks my location in.
[EVO Shift 4G General] yokken:
mine took a little while to initialize (indoors) but it locked in within 30 seconds.
[EVO Shift 4G General] DWake014:
No issues here. Inside my GFs apartment it locks very quick and is probably about 5-10 feet off according to google maps. My moments GPS never locked or worked so I'm extremely happy with the GPS quality on this phone.
[EVO Shift 4G General] cosine83:
The first lock took around a minute to get. Now it gets a solid lock in just a few seconds, if that.
[EVO Shift 4G General] NuAngel:
A little off. Not as bad as my gfs Samsung Instinct, but it does often have me a few hundred meters from my actual location.

[EVO Shift 4G General] riggsandroid:

When it does work it is not as accurate as my Heroc was. Hopefully this gets some love in any updates.
[EVO Shift 4G General] cosine83:
GPS is great for me. The only issue I've run into is that when I go from Maps to Navigation, my SD card gets mounted as read-only for some reason.
[EVO Shift 4G General] plmiller0905:
I know a couple of days ago I tried to use my Google Maps/GPS and it couldn't get a lock on me. It was like going crazy or something. However, it was snowing and kinda foggy so maybe that had something to do with it. It worked the next day though when the sky was clear.
[EVO Shift 4G General] karnoff:
No gps lock on my end either. Also tried the gps status clear....nothing so far

EDIT: just opened maps for about a minute or so and it locked finally. Closed maps then opened again, locked within seconds.
[EVO Shift 4G General] tokuzumi:
Bumping this thread: I have issues with getting a GPS lock. If I open Google Maps, I'll never get a lock (at least not before the phone goes to sleep - 60 seconds). I open up GPS test, which I downloaded from the market. It gets one satellite to lock right away. Sometimes two. Then it takes forever to get 3-4 more (at least 60 seconds). I can then go into google maps, and it will get a lock within 15-20 seconds. But if I let the phone go to sleep, and open up maps again, I don't get a lock, unless I do the GPS test. And sometimes that doesn't even work. I've done the GPS Clear thing, via the epst codes (##GPSCLRX#), and that doesn't seem to do anything. I'm running the MikShiftG 1.1 rom. I'm going to make a nandroid backup, and see if that happens on a stock 2.3.3 rooted rom.

Hey guys I've 2g connection.. The plans is of 2mbps but my speed is damn slow.. I sometimes get 3 to 4 kbps max..rarely downloading speed goes above 10..I've been using byte tornado but no use...

Late nights the speed increase but during the day the downloading speed is damn low...

The uploading downloading indicator next to battery seems to stop while downloading bigger files..

But recently while using tube mate (youtube downloader) I've been experiencing very good speeds..the videos of over 25 mb hardly took 5 mins or so...the app seems to suck internet speed to get more speed...

Is there any application that allows us to do the same while downloading movies or songs etc
[Android Software Development] fredley:
Hi guys/gals

I'm working on this app for my final year dissertation. It performs Echo Steganography on wave files. My app uses this to encode short text messages in an audio file, then share it. I've just got the Steg side of things working, so I wanted to get some early feedback on whether it works for other people (and if it's awfully slow - it uses a lot of Fourier Transforms etc...).

This is very early days, so the app isn't anything like ready for primetime yet, but the basics are in place. I'd really appreciate it if you could download it and:

* Have a go at embedding some text in a recording and seeing if it correctly extracts it again.

* Run the tests available in the menu

* Email me one of your recordings (tfmw2 [at] cam [dot] ac [dot] uk) to see if I can extract the data on my phone.

* Supports encryption with a shared key

* Transcodes audio files to ogg format for sharing

Updates (0.75)

* Added Multicasting of messages to contact groups

* Fixed bug with sharing files in paranoid mode

* Better memory management, should work more reliably with longer messages

* Reduced error rate (less garbled messages)

* Reduced file size by 33%

* Other bug fixes

Any problems let me know!

Cheers
[Android Software Development] tridge:
I'm not sure what this does =\
[Android Software Development] fredley:
The app records a file from the microphone and embeds a secret message into it. You can send that file to someone, and if they've got the same app they can extract the secret message from the audio file. Anyone listening to the audio file wouldn't be able to tell that it's got a message hidden in it, as the difference is hard to distinguish with the human ear.
[Android Software Development] fredley:
I've uploaded a new version, it's a bit more stable and a bit easier to use!
[Android Software Development] 00Ghz:
Interesting, maybe we can team up this will be an interesting feature for my project
[Android Software Development] Meltus:
Works pretty well, cool idea too!

I was able to make it fail though by using a long jumble of letters (I screenshotted before and after to compare) but it still only got about 5 wrong (little diamond with a ? In the middle).

Nice work!
[Android Software Development] fredley:
Thanks Meltus

Could you let me know the length of the string. Were the wrong characters at the end or distributed throughout? What kind of audio input were you testing with (voice message, background noise, music etc.)?
[Android Software Development] fredley:
Update

Now supports basic crypto. Run tests from the menu before you start to check the crypto test passes (if it doesn't, let me know!).
[Android Software Development] Meltus:
Length of the string was about 30 characters, the wrong characters were distributed and were just regular letters.

As for the audio it was just me tapping on the mic for about 20 secs.

I've been doing more tests too and it only seems to occur when you have a few repeating characters. I typed out the keyboard lines and it got it correct, until i started repeating every other character a few times, then it started to get a few wrong.
[Android Software Development] fredley:
That's strange! The embedding works bit-by-bit, rather than byte-by-byte, so it's very strange that repeated chars should cause an issue. I'll look into it though. Did you try the same test with continuous sound, such as music? I'll see if I can replicate it here. What hardware/android version are you using?
[Android Software Development] kuelexx:
Are you using a set algorithm to code messages and decode them? Or does it shift from how long the coded message is to the non-coded message? This is an interesting app that could serve a lot of uses, excellent idea! Hopefully this is seen all the way through to "perfection", its a keeper.

I will be watching this blog closely and will test the app. Cant wait until its totally complete.

--CueSA
[Android Software Development] Meltus:
I'm using a Nexus One with 2.3.

I didn't try it with other types of sound so it's not the most accurate of tests, but i'll have another go today.
[Android Software Development] fredley:
I've had some issues with occasional chars being wrong, I may put in some kind of CRC, but I don't think it's that serious. It may have something to do with various microphones and their sensitivity.

In other news, now upgraded to version 0.4, which converts encoded files to ogg format, and can extract messages from ogg files too! (would be a bit silly if it didn't). Files are ~90% smaller as a result!
[Android Software Development] ledridge:
I could see an RDS type implementation or advertising uses that would let you encode whatever data you wanted in the audio if the mobile app did something like SoundHound where you could have it listen for the message. If you could create a background app that listened for any messages and alerted when heard, without totally draining the battery, I could see implementations with nielsen ratings showing accurately what you saw and when.
[Android Software Development] fredley:
I believe this tech (or at least, steganography in general) is already used to watermark copyrighted material, in some cases uniquely. Authorities can then look at an illegally shared file and trace its origin or something like that. Certainly it's possible.
[Android Software Development] fredley:
Just updated the version on the market, now integrates much better with email apps/file managers. Let me know if you can't launch StegDroid from your favourite app!

ringtones?

Just in case this never occurred to you: When I tested it out, banged in a message and then got to the recording part, I was kind of stumped as to what to record so I just started rambling. That's weird if someone listened to that, my sending my own voice. And were I to turn on some Led Zeppelin track and record that, either making a short recording of my voice or a lousy 15 second recording of the Rain Songin mono, that would be an odd recording that would stand out on its own.

So I'm thinking, now what audio might someone casually and inconspicuously send from one phone to another that wouldn't look to bizarre were someone to see or intercept the email -- sending a buddy a ringtone maybe. And on Android those tones are oggs I believe and maybe stegdroid could loop and stitch them however many times as needed to squeeze in a message and then cut the looping off, as phones do when they ring. The program selects a ringtone at random or by choice, and stegs in the message.

?
[Android Software Development] fredley:
Interesting idea, I may look into it in future. I don't know if there's a central repository for oggs that can be accessed programatically, but I may be able to get the app to let the user choose whether they want to embed/extract from an ogg that they open with StegDroid.

Interesting to see the 'Voice to Tweet' services that sprung up in the wake of Egypt's big disconnect, that would be a great way of distributing your hidden messages (the great thing about steg is you can broadcast your message publicly on Twitter, and only those with the right software and password will be able to access your secret message).
