Wish: Interactive phone feature test before you buy

Hi ... I called this Wish: cause its more of a Oh this would be cool kind of thing, plus I thought general would be an okay place to post this.
I wish there was a website or app you could download where u could interact with the type of phone u wanted.
So like I have a wizard ... I would be able to point to start phones look at the settings look @ all the types of wifi settings etc. Not talking about an emulator but more of some thing like a look @ all whats cool before you buy so like if the screen had a touched screen you could use your mouse to click on things while if it did not have a touch screen you would keep clicking the buttons
I dont know its just an idea ...while I am wishing I wish some of the people who develop these phones (cough HTC/hp etc) would have something like this on their website....I know u can look @ 360 degree views of models but why not have interactive models ?

Life after TyTN

Hi all,
Well, it seems that come July, I will be forced to move on from my Hermes. I will be changing work locations to an area that allows PDAs, but not with cameras.
So, I'm looking for a new phone with the following:
- No camera
- 3G
- WM6 (at least can be flashed to)
- built-in GPS (for cycling)
- bluetooth
- full keyboard (I'm thinking I want front kbd or slide-down over side-sliding)
- enough interest on this forum to make life fun with hacks and tweaks
I don't really play games or watch movies, but plan to use it for audio a bit.
Any recommendations out there?

I think its gonna be hard tofind one without a camera.. What about buying one with camera and then take the camera out of the phone ?
Unfortunately, if it looks like it had a camera at any time, it will probably be confiscated (military installation).
Looking around, the Kaiser seems to be the only option.
Does anyone know if they plan on making a Polaris or Niki w/out camera?
I don't think you will find a phone with that spec, without a camera, and tbh I don't think removing the camera will suffice, as it can easily modified to take pictures again. But I don't know of all the security restrictions your work place has.
I presume that you are on AT&T. While not readily available at retail locations you can order all sorts of devices with out the camera. For instance...
The AT&T 8525 has a model with no camera... 8500 (I think)
AT&T Tilt... 8900 maybe 8920 either way they are just a slight model number adjustment.
What phone would you like? Call AT&T customer support and they can advise which devices are available sans the camera option...

App Ideas? Share them! Developers come look!

I see alot of threads around xda requesting miscellaneous apps or ports. I have written down a lot of my ideas and I'm not quite to the stage where I can make them myself, and I'm sure a few others are in the same boat. I don't see much of a point to keeping them a secret when there are alot of capable developers around here. If there are developers out there with free time that see a cool idea in this thread, try to give a mention to the person if you create the app!
3rd party app toggle
Just an app similar to adb toggle, that quickly toggles on 3rd party app installs. It's not secure to leave it on all the time, and for people with settings locked it can cut the time taken to install a 3rd party app. If you're an overachiever try toggling all app installs, not just 3rd party.
Password Scanner
Basically an app that just scans /data for SQLite entries and lists items associated with password fields. Plaintext is enough to make it useful for a lot of people, with options of a pro-version that cracks encrypted passwords.
Car Remote
This is the most challenging one I've thought of. It's an app that uses the device's radio antennas to unlock cars that have remote control locks. I've looked into it and the encryption looks tough to break, but if you're a genius you can probably figure something out. Here's something to get started: auto.howstuffworks.com/remote-entry.htm
Time Machine
I thought of this while reading en.wikipedia.org/wiki/Year_2038_problem
A mod/app that messes with the clock to cause app compatibility issues, which could enable potential root exploits on devices which don't have current root methods. This one is risky because it is likely it result in bricks (yet another use if you want a device to be bricked in the event of a theft). I'm unsure if something like this would need root access to work.
Share your ideas! My apologies if any of these have been thought of, it wouldn't be the first time I've rethought the wheel.
Wow, some nice ideas there! 3D party app can be a popular one. I also like the car remote app idea, but will it be helpful?
Found this video on a PDA for the car remote, it used infrared though..
Time machine looks interesting but can it be realized !

oh don't let me get started on the list of ports I want haha. Top 3 would probably be cain & abel, cisco packet tracer, and something like encase.
cs6 is would be nice for sure though, adobe is really slacking with their tablet app. I see something like gimp coming before photoshop due to it's source being more available.
i would really like something like frozen synapse on a phone i think it would work really well.
Make an android rom for the samsung brightside instead of its Brew, and you give 50 thousand people a boner...
its the only smart-ish phone that can be used on verizon without upgrading to the smart phone plan.
if it gets a rom,you have a verizon phone and dont pay the bastards the smart phone fees
I would love a hearing aid app to control the different settings.
Would be amazing!
Car remote app will never work as each car uses some sort of encryption and frequency to unlock the door while the phone antennae can only transmit on 2G/3G/4G frequency bands.

and bluetooth, and wifi, and gps. There are a number of antennas in each phone. The one in the video I posted managed it with infrared.
I think car remotes work on the 400-500mhz spectrum so it will take some research to how compatible it could be with most phones, and that's not even exploring dongles.

All these antennae are not capable to transmit in any frequency band, they have been hardwired to operate on a particular band to save money and be power efficient.

ANT+ Coming to All Galaxy S4 (And All New Samsung Flagships in the Future)

Ray Maker of DC Rainmaker on Twitter reports ANT+ is coming to the Samsung Galaxy S4 through an October Firmware update and will be supported on all flagship devices going into the future
dcrainmakerblog
"We will support ANT+ in the Galaxy S4 in a firmware update coming in October" - Samsung (at the ANT+ Symposium)
dcrainmakerblog
"We do plan to support ANT+ on all of our flagship smartphone devices in the future" - Samsung (at the ANT+ Symposium)
Ray now has a blog post about this:
http://www.dcrainmaker.com/2013/10/samsung-mobile-devices.html
Particularly for anyone with sports data tracking devices this is huge news! Not to mention ANT+ is pretty simple to implement now with the new Plugin services they're bundling with the Note 3 right now
ANT also allows you to build really neat wireless topologies as well if your into that stuff, plus it supports full multicast as seen on DC Rainmaker:
http://www.dcrainmaker.com/2013/09/curiositysurvey-different-cycling.html
A little background on ANT and ANT+:
ANT is a mature ultra low power wireless protocol running on the 2.4 GHz band like WiFi and Bluetooth. Bluetooth Smart is a protocol similar to ANT but architected around Bluetooth style bonding/pairing with several connection layers and services.
ANT is a compact and flexible protocol, allowing virtually any type of wireless network topology to be created. ANT transmitters automatically manage coexistence and divide the RF channel they are transmitting on into timeslots, which means any number of receivers can listen to an ANT device, excellent for gyms, training areas, anything which requires a large number of transmitters, as ANT can handle potentially hundreds of devices transmitting to an infinite number of receivers.
ANT+ is a set of interoperability specifications called "Device Profiles" which means devices which use them are able to "talk" to one another. ANT+ has reportedly shipped in over 60+ million devices globally, predominantly in Sports and Fitness (Adidas miCoach, Garmin Watches, Running Sensors, Heart Rate Straps, etc).
Why does this matter?
Right now, it only matters if you're into any type of sports or fitness training, or if you have an idea which requires 600+ transmitters communicating to XXX number of receivers simultaneously. As a nice bonus, any ANT+ device is compatible with any app as long as it's certified.
For developers
The ANT+ API appears to be much simpler to implement than the BLE API. The ANT+ API already handles device discovery and decoding of data events from sensors into the useful data without even reading the Device Profile. You just request access to heart rate, cadence, etc, and then subscribe to the event handlers which pass the data to you decoded. The BLE API still requires a lot of work to do the decoding properly, handling characteristics, etc
ANT+ Plugin API - Supported from Android 2.1+
http://www.thisisant.com/APIassets/.../plugins/antplus/pcc/AntPlusHeartRatePcc.html
BLE - Officially integrated from Android 4.3+
http://developer.android.com/guide/topics/connectivity/bluetooth-le.html
Some Apps which include ANT+:
-Google My Tracks
-Endomondo
-Sportstracklive
-Garmin Fit™
-Run.GPS Trainer UV
-IpBike, IpWatts, IpPeloton, IpSmartHr
-Selfloops
-SportyPal

Right now its used mostly in sports and fitness although some of those device profiles they've implemented are branching into things like remote control like the O-synce bike handle bar remotes. They submitted patches for Apollo but the developer's busy with other features ATM.
sounds like bloat..

It depends on how you use your phone.
For fitness addicts like me, that is good news.
In general, there are different protocols to transfer the data from your heart rate belt. Most devices for home use like spinning use the ANT+ - protocol. Others use the Bluetooth 3.o 0r 4.0 protocol.
BT 4.0 LE (Low Energy = battery saving) is implemented to Android 4.3. I am guessing that it is the same with ANT+.
Benefit for Android-users: You can use your heart rate belt that you use with your home device also with your Android phone

it's an interesting move for Samsung to make. Considering they and their competitors are bringing out smart watches using bt4 and android 4.3 standardising bt4 api. It was starting to look like ant+ was going to lose the smartphone market. Perhaps they cut a deal with Samsung

Honestly, Ill believe Ant+ inclusion when it actually happens. BT4 smart has started to catch on with cycling manufacters, both Topeak (currently) and Wahoo (soon) will be able to use bt4 smart sensors soon. I saw a S4 at Interbike hooked up to a BT smart heartrate monitor and speed/cadence sensor.
This was big news to me, as for a long time without a dongle (super annoying) there was no way to use an Android phone with speed/cadence sensors or heartrate monitors, unless you had a sony.
If Ant+ doesnt pick up soon, its going to be left behind. Android including BT smart in 4.3 is going to change the field for newer phones.
I too would like to see some documentation/references about Ant+ inclusion.

After flashing the 4.3 leak i noticed some ANT library packages in the 'installed packages' list.
I found the app "ANT+ Demo" from the app store and it is reading my ANT device! It's already working!
It is working with an ANT+ development kit i have here on my desk, haven't tried it with any official devices yet.

What "4.3 leak" did you flash? Can you tell us the rom? Can we have some links/references? Where do I get the packages so I can bribe some S4 cook to bake it into some rom? (or am I missusing the term?)
I use ANT+ to upload my running activities from my garmin watch to the garmin website. As the watch can only comunicate via ANT+, I either have to have a PC around or, when in holiday or somehting, I have to use a micro usb otg adapter and connect the ANT+ dongle to my samsung s2 using an app called garmin-uploader (along with a coupple of ant+ services found on google play).
There is something that I don't quite understand here.
Does this mean that these devices listed (s4 and s3 I believe) were already shipped with ANT+ capable hardware?
ANT+ was therefore already possible on them by using the ANT+ radio service available on google play without the need of an ANT+ dongle right ?
If not, and the hardware has to be enabled somehow with a propretary driver of Samsung, how about the Samsung S4 Google edition? Those don’t have a Samsung customized ROM but a google vanilla Android right?
Also, DCrainmaker wrote a post about the matter :
http://www.dcrainmaker.com/2013/10/samsung-mobile-devices.html
I see the lack of balls in Samsung to not include the S4 active to get ant+. It's worth pointing out amoled screens are organic and have their life degraded by heat as well as UV light.
there's some photos posted a couple times on xda forums where someone bought a store display s3 or note 2 that had the original screen sticker decals shadow burnt into the screen. In fact it was the rest of the screen that was exposed to the light that had degraded. The sticker decals had shaded the screen and not degraded some parts leaving their shape visible on a white screen.
I suppose it doesn't matter for indoor sports at least...
here's a couple of examples a quick Google search pulls up

Do you have any ANT+ equipment to test with an app? (Believe endomondo supports ant+ HRM)
Considering updating to the leaked firmware, but the whole KNOX thing is making me a bit reluctant...
Unfortunately I don't have any supporting equipment. I am one of the lucky ones to have got the leaked 4.3 without getting knox installed but I wasn't really bothered even if I did. It's just a warranty void. It's actually very hard to brick an S4.

Great news. Another 10 or more MB spent on software which is dedicated to communicate with specific hardware, and if you do not have such, it will be silently running in background consuming the battery and memory.
I have advice foe Samsung: guys, please do not forget about the dedicated BT controller to very common equipment like Boeing 737 or Airbus series 3 (310, 319, 320, 330, 340 380 etc.).
These planes are really popular nowadays and each pilot would really appreciate if he could for example control the flaps while playing Jewels

Android Smart Ring - A Step Beyond Possibilities

Production of this Android Smart Ring can start soon as soon as some Big Device manufacturer lays his eyes on this ( I mean when he/she gets to know about this project ). Hopefully Google should be attracted towards this
The Android Smart Ring is an inspired device from smart-watches but has an unique Design,Specifications and can do beyond possibilities.
Watch Video HERE
I am an College Student who got this project Idea. I just want to give this project a Go and see if I can make it a success. I wanna give people a whole new experience of Technology. It's a unique Idea which has never been done, if previously it's done then that must be not as good as this one. The Android Smart Ring features a curved 720p display, Bluetooth v4.0, NFC, High Clarity Speakers, Microphone, powered by 1GHz processor, 512MB RAM, couple of required sensors, has Transistors (acting as a battery which requires no charging) and this ring runs on Android KitKat (or) Android Wear (in near future).
Keep Sharing this Idea and let each and every men know about it. Help me making this Idea an reality Thanks for all your support in advance.
I don't think I understand how you intend to incorporate a 720 P display on a small ring along with a whole bunch of other hardware
I don't think we have hardware capabilities to make your idea feasible at this point

What this dude says is true. It's only possible if you created a time travelling machine and travel to the future and retrieve the techology from there, now this is definitely a viable and possible option for you homie.
Okay.. Wait a min. So, you guys think that this isn't possible. Let me tell you one thing, you must have heard about Phonebloks, right ? Was it possible back then ? Hell no, now Google has taken the project and made it possible. So, nothing is impossible
I would think scale down what you are expecting out of it, maybe not 720P display. Start small, and work your way up. See if you can get a working prototype first even with a basic display that might be small, because 720P is quite a big ask for what I would imagine to be a very small device.
Analyse it from every possible angle and lens you can think of. Here are some examples to start you off: Technical ability of construction, marketing, corporate usage, end user.
Here are some examples:
Technical:
Start trying to see if you can get electronic components small enough to even complete something like this first. If you can, what's the limit available today? Maybe you can't get a speaker small enough, so you work around not having that. Work out where your limits are.
Then let's say with marketing: Who are you trying to sell it to? How can you convince them to buy it? Does it provide any perceived value (not necessarily actual value), or will people see it as an expensive paperweight?
Corporate usage: Could you display advertisements on it without being too intrusive from general functions? Could it be used in a corporate setting, add any value to business running?
End user: Will it be comfortable and easy to use throughout every phase including charging, or would it overheat and cause discomfort? Will it last? Can it be adjusted to suit the needs of people (e.g. different finger sizes).
Give this a thought, and work out if you can provide solutions to every aspect, and identify potential problems BEFORE you even hit the market. You wouldn't want to go through extreme difficulty to process and manufacture it, and in the end it flops badly because of overpriced/poor quality, or maybe simply nobody wants one.

Well, I haven't just though about the production and all because I ain't ready to do that, I just provided a concept (or) an Idea and asked people to share it if they liked it and then maybe in the future a company might notice this Idea and bring it to reality. I never thought of bringing this thing to production by myself (coz I ain't a rich guy). Speaking of the speaker, it can be replaced with vibration alert which will be more effective (it can be annoying too) for people to never miss an message alert (or) call alert or whatever notifications you get.
When talking about marketing and corporate usage, well there's always a way to target everyone around you for it. However, it just requires an simple yet effective Idea to present in front of the public and it won't be expensive (deduction of specs to low-end ones would help).
Of course, it will be comfortable and easy to use. It's just same as your usual ring replaced by this Tech things from which you can see what's going on your device without a need to take a look at it by taking out it from your pocket. It's just a device which shows you alerts about your notifications and allows you to send messages directly to your colleague by using microphone (voice messaging service).
I Hope you are satisfied. Feel free to ask more questions, I am happy to assist you and NOTE :- It's just and Idea which I haven't thought to bring in production by myself.

Just the part about a small 720p curved display, it can be done for sure but at the cost thats can scale into production? I don't think so! if it was Samsung would already make this kind of device
sent from Carina Nebula with my Nexus 5 inter dimensional cruiser...
I think you need to do some searching and find out for yourself that current technology is not there yet.
Google some of the components you're saying will be in the devices, then look at the smallest ones available. It's just not going to work.
Transistors? They won't be large enough to drive the hardware, if you can find them that will fit in a ring.
720p screen? Why? It's on a ring. Anything at that resolution is going to be UNBELIEVABLY SMALL.
High Clarity speakers? Aside from being extremely vague, you show that you have no idea how this technology works. Get some bose earbuds. Their quality is great. Then again, look how big they are. If they could make them smaller, they would. Hell, even hearing aids aren't that small, and their quality is acceptable at best.
1ghz cpu? Find me a 1ghz ARM cpu at this size. They're not available yet. The manufacturing process just isn't available.
512mb ram? Again. The chips aren't going to fit.
Maybe you can get some of these things into a ring, but definitely not all of them. The technology just isn't there yet. I don't mean to discourage you from your goal, but you really just need to be smart about it. Patent your idea, and keep your eyes and ears on the tech world. Be realistic. When the technology is available, you can bring your product to market.
