I may be wrong, but:
https://play.google.com/store/apps/details?id=org.prowl.torque

ive seen these, they just read parameters from the computer via the obd diagnostic port, what i meant was actually removing the the obd computer and using an android device to receive the incoming sensor data and use the data such as rpm, throttle position, and so forth to advance or retard timing tables and fuel tables to actually run the engine i have tuning software for my honda that i can run and retune my engine with but only from my laptop id like to be able to do this with an android device.

[A] 😉 let me know
That's an interesting question and not what I thought it was when I first read your initil post. Reading it literally you're asking about replacing the actual 'brain' that conductor that co-ordinates the entire ignition,fueling,emmisions and other secondary parameters that make the engine run in a harmonious symphony(oh, whatever happened to self metering by atmospheric pressure drop and contact breakers lol). I read it as taking out the OE ecu/ecm/powertrain module or whatever other term you use for it and replacing it with an android device. An interesting exercise but hardly worth the mountain range of problems involved considering you can go out and buy a custom fully programmable ECU anyway.
That is how it sounds though when you say replacing the ecu with an android device. i.e removing the ecu and putting in one running android or a piggyback ecu running amdroid....... i know, i'm being maybe a little too pedantic but it drew me in and made me read the thread and am definitely interested in finding out if there are any android apps that can reprogram or flash an ecu similar to the ones that run on windows.
I've mentioned in another thread I have a deep knowledge and experience in the car side of the equation but my knowledge of computers themselves ranks about 'interested in knowinf more but basically capable of using one n that's it' level. Or tge same as 99.99% of car drivers. They can drive but beyond that all they really know is where to out the petrol in although 100,000s of them will say they know all about cars lol.
In other words, I see know reason why technically there are no equivalent android apps/devices that can do what software packages running windows you use on a laptop. I'm in a similar but different position than you. I really want that ability to remap/flash new firmware onto ecu's except right now I don't have a laptop or desktop of any kind right now. All my online and computer needs are admirably dealt with on my Note 3 so i haven't bothered replacing either my pc or laptop when they passed on.
Was on ebay recently and seen very interesting and potentially useful software claiming to be able communicate fully with any obd1 and 2 ecus allowing you to reset, remap and 'chip' any ecus and also fully set up a new replacement custom reprogrammable ecu too although i am skeptical you could buy one that fully capable for £20 off ebay but they promise full customer support and the ability to download an entire remap for almost any make amd model so perhaps their claims are based on the abilitynof their product rather than merely sales rhetoric.
Anyway, what I mean is I see no reason why if windows can fully communicate with obd2 and android can also read current and pending dtcs, display freeze frame, live data and allow you, if you know the particular formula, to view data with custom PIDs then it seems possible that a software package written for android couldn't be capable of doing wnat these windows/mac programmes can do. I'm sure I've seen linux compatible software for desktops out there so surely an android version is poasible. BUT as i explained my knowledge of computer systems/languages is risible so there may well be a glaringly obvious reason that android is unsuitable (there's probably 1000s of 10 year olds laughing lije mad thinking is this guy stupid or what lol).
BUT if you ever come accross such an software package that runs on android let me know because if not it looks like I'm going to have to go buy this 20 odd quid ebay software AND a bloody laptop on top to bw able to use it

which android phone has the most powerful GPS chip?

Hi,
Can you please let me know which android phone has the most powerful GPS chip?
I want to develop a custom android navigation system and I want to deploy on a phone with very powerful GPS chip so it work everywhere.
thanks.

I don’t know... But I would think if you are developing an app you would want to target the most sold/prolific android phones... regardless if they are the "most powerful" or not.
What if the most "powerful" is a phone that doesn’t sell much?
The solution is GPS and positioning centric. At first I looked for Navigation devices but none of them is based on Java or Android so I can not develop my application for them.
I decided to use Android based cell phones as they both have GPS chip and I can develop application for them easily.
Thanks.
Ok cool... So focus on all the newer Android phones? HTC, Motorola... LG has a low end now...
You really want to just develop for the HD2 or Droid X? Would that even be practice or possible?
The customer will buy any device I ask for his employees, so I will have no problem regarding the application being locked for only one type of devices.
The only thing that I need is a Android based device with good GPS capability.
Thanks
Ok.....
Well I find it hard to belive older devices would have better GPS...
I think all new phones probably have the same GPS capibilities?
Or look at the Garman?? Wouldn't the phone made by a GPS compnay have the best GPS?
I actually have a pretty good background in GPS. I can’t imagine what you are getting at. Either it’s just another GPS app that most phones can do or you are talking about an app that would do survey level GPS. That of course would require a base station and no phone would have that because it would be ridicules for any manufacture to make.
So what is it you are you trying to do?
I need to develop a software in which the office sends a coordinate to the phone via USB cable or bluetooth, the employee take the phone or the GPS device and then move to the location specified by the office and deliver a package.
When delivered the package, employee need to fill in a form about the package delivery conditions. The application must not allow the employee to fill in the form unless he is in a proximity of the delivery point. for example 50 meters away from delivery point.
I can only develop software in Java and so far I was not able to find a dedicated GPS device capable of running an android of Java application. So I thought the Android phones are the best options.
thanks.

So... dont you know.. Almost all new phones have the same GPS abilities? You think one is going to be better than any other? Again... GPS is pretty basic.. Blackberry, iPhone, Android... They are all using the same chip...
Come on... You think HTC is going to say "we will show you 2' closer than the other guys!!! Buy us!!"? Who the hell cares?
And 50 meters?! Almost all phones on the market do way better than that! My Droid not only finds me within a few feet but even know what direction I’m facing standing still!!
Well,
It is correct that all new phones do GPS better than older phones. But a dedicated GPS device lock in less than 10 seconds in-door while a cell phone may not lock the position in 30 seconds.
I am mostly looking for a better GPS support for locking and reception reasong.
Thanks.

Ok I think your best bet would be to ask around on some actual programming forums because it seems like half the people that are responding to you aren't even reading your post fully.
As far as GPS signal strength and accuracy goes:
All HTC devices within the past 2 years...
The upcoming Samsung device line...
And Motorola devices STARTING from the original Droid...
Anything after that will more than likely have very low quality parts, meaning very shoddy GPS chips as well.
Good luck on that program, bud.
hi Legolas
did you end up developing this program?

Android In-Vehicle Infotainment

So I've had a project for the last few months getting Android running as an infotainment system. Here is a demo i thought i'd share with you guys..
http://www.youtube.com/watch?v=fNcDq9S8n3I
Basic features:
Android 2.1 (looking to update to GB)
7inch touch-screen (800x480)
3G modem
GPS
Reverse camera (backup camera to see what's behind you)
USB port
would love to hear some criticism or anything regarding the device.. its not perfect, its got a few bugs and glitches.. but is sort of ready for everyday use but is missing a few components to make it 'official' android device (wifi, bluetooth etc).. but i'm just wondering if anyone is interested in something like this? Is this worth developing further on?
This thing runs on Cortex a8 omap3530 board and is based off 0xdroid build.
apologies if im in the wrong forum
Wow dude, thats really cool! I'd love one of these for my car. If you could get Honeycomb on that bad boy it'd be sweet! Just wondering, how do you plan on setting up a rear view camera? Just connect a camera at the back of the car to the tablet itself, then run the Camera app? Seems like the simplest way to me..
Haha cheers love to see the honeycomb source once its out then we'll talk although I'd imagine i'd need better hardware...
currently camera is interfaced by usb (has a usb hub) so i got a cable running under the carpet through the boot then camera is mounted on the bumper. yup camera is called by any camera calling intent.. so any app can use it.
I want to get some proximity sensors (like parking sensors) and write a proper reverse cam app to complement it. But we'll see...
Very cool!
I've been wanting to do this for a while, but I was going to use MeeGo or maybe Moblin since I don't have the programming skills (or Android knowledge for that matter) to build my own computer around Android. I dig what you got so far though.
My suggestion for the reverse camera is one of two things, because it would bug me to have to find and open the camera app every time I needed to back up.
Keep your touchscreen (what model are you using BTW?) and use a bluetooth or wi-fi relay (I know they make 'em, but they are $$$) to provide an input from +12V signal from your reverse light wire to automatically open the camera app, then close the app. Of course, you'd have to program for that.
Or
Have you considered this touch screen? Lilliput 7" touch screen with auto-reverse input. (Needs a RCA camera though)
http://store.mp3car.com/Lilliput_629GL_70NP_C_T_7_VGA_Touchscreen_w_Aut_p/MON-016-0002.htm
This is the one I plan on using since it switches automatically to the camera input whenever you are in reverse. Once you go back to any other gear, the OS input shows up again.
Just a thought to make life a little more convenient (although you already bought your parts so you may be stuck.)

Thanks a lot! It needs a lot of time and dedication but it's a real good learning curve. I had to learn a lot of things on the way.. especially c/c++ I wasn't great at but had decent skills with higher level programming.
If you are planning to work with MeeGo its a little fussy with the hardware requirements.. Correct me if i'm wrong, but I think you need an Intel Atom processor. These are a little pricey if you're after an evaluation/hackable kit! But I'd imagine it'll be easier to program as it's a lot more closey coupled with linux.

I just had a look at those relays, sounds like its something I really need! Is this how the standard backup cameras work? That was something I was confused about.. I wasn't sure how to detect if i'm on reverse.. especially with the parts I already had. I'd imagine once you implement it you just need a service running in the background to listen for the relay.
The touchscreen is a TFT resistive 4wire touch-screen. It's not something I want to keep as I really want capacitive multi-touch.. But this fits perfectly with the board and was easier to deal with

I think most factory backup cameras use two inputs and switch between them. I don't have a lot of experience with them though.

Not sure what you mean exactly. I'll try the relays because it at-least gives me a standard interface to work with (bluetooth or wifi) so there isn't any work you have to deal with on the hardware abstraction.. Although it would probably be better designed if I had some sort of voltage input coming when the vehicle on reverse (the reverse light as mentioned). But I don't really have the electrical expertise to make it happen lol.

Well essentially what I was thinking was you'd have the bluetooth relay hooked up to your reverse light wire. This should allow your computer to monitor whether or not your car was in reverse. Relays are pretty simple - one input switches on/off another, usually one of a much higher or lower voltage. So in essence, it's a switch activated by voltage. (There used to be an electromagnet inside that physically moves a piece of metal to make a connection when a voltage is applied - now it's all transistors and whatnot.)
So, if you are in reverse and your reverse lights are getting power, the bluetooth relay should sense that and signal the computer (through a serial command it seems) which in turn could tell a background service to open the camera app. Once the voltage from the reverse light wire is lost, the relay should again tell the computer that you aren't in reverse anymore and the background service would close the camera app and re-open whatever app you were in.
*I should note this is all "in theory"... I don't know exactly how those wireless relays work/communicate and I don't know Android programming at all.
Thanks for the feedback. I was thinking what about using the GPIOs on the board and attach that to the reverse light? would that be possible? and using some resistors on the way to limit the voltages so i don't fry the board.. but we just need to detect some voltage input...
Not sure, will look into it. Right now, taking a pause on the development.. Got a lot of work to take care of but I can't wait to get back into it. I really want to port this to gingerbread.

You could possibly do that, a real cheap voltage regulator would probably be better though. You could also use a cheap relay if the correct voltage is already somewhere on the car. Again, I'm not too sure how those bluetooth relays work, but it sounds like you are on the right track.
Great Job!
I was thinking of doing something similar myself.
I am looking at going with one of the tablets as it is just seems easier? I only really need internet, google maps(GPS) and wifi tethering. I would imagine you are running stereo sound from a 3.5mm? I would still have a seperate head unit to control volume and handle all the regular functions as well as inputs from a 3.5 to RCA cable.
How are you running sound off that setup? Are you running a head unit still?
The sound is running off a small amplifier. then RCA to 3.5mm.
Haven't had the chance to play around with the wifi tether as right now i don't have a wifi card.. It would make sense to have wifi tethering or just wifi reciever and use a phone to tether 3g to the system. Avoids having separate data plans.
Can we get a copy of your "AIVI Car Home" for our own DIY projects?
I don't mind releasing the source for it. Its just right now its a bit messy and quite a few things are hardcoded.

Nice project. I gutted a Clarion Mind last year to do pretty much the same thing but am looking to upgrade. You said the software needs work but it's a real good start. Would you mind sharing your hardware list with us?
Nice work!
Something I was also interested in seeing is having vehicle manufacturer recommended service intervals and such available as reminders from your in car system or phone or both.

You could use 'aCar' which, if you are unfamiliar, you enter the make, model, mileage and all the pertinent service requirements. Battery every 3 years or 50,000 miles, coolant every year or 15,000 miles, oil every 6 months or 3,000 miles, etc. Then, every time you get gas you enter the current mileage as well as gallons/liters of fuel and the price. From that information you not only get your MPG but it will also trigger reminders to do the necessary maintenance at the correct intervals when they come up. You can do this for multiple cars as well. It's a very good program.
On a related note to this thread, I started my own 'carputer' project using an Archos 70 Internet Tablet and an unused articulating wall mount for TVs. It's still a work in progress as well since I don't have all the parts yet but will do everything I wanted (eventually... lol) except the rear facing camera. The video is obviously just of the media player.
I shot this late last night to show a friend. He wanted to know why someone would want a tablet/computer in their car, lol. Sorry about it being so dark.
Dude
I am keen as mustard on one of these beauties, I was considering running xp MCE but the android option would be much nicer..
Love ya work.

petition for legal modding and warranty

You know what bugs me already for years is the following...
Mobile phones, which I paid a lot for, come with poor vendor roms, which are locked. They are mostly rich in bugs and therefore poor in bugfixes, support and updates.
xda-developers mod roms, cyanogenmod, android root and so on are such great projects...
The problem with those is, that
- warranty gets lost
- not available for all phones (there are for example no mod roms for Motorola Flipout, because the bootloader has been successfully protected my Motorola and no one could hack it yet)
- the developers have to waste time with working around the protections to mod the device
It is ridiculous, you paid the full price for the phone, but never get the right to fully use it's potential.
Let's compare it with buying a normal laptop. It's also a piece of hardware and mostly there is Windows preinstalled with a loads of bloated unwanted software. This might be ok for a lot of people. And the rest? They are free to install ANY operating system they wish.
On normal laptops there are not risks when messing around with new operating systems. Of course you need some knowledge and you may lose your data, if you do not know what you are doing. But since all my messing with operating systems for PC, I never damaged the hardware, simply it is designed in a way, not to be damaged by software, it's robust.
Mobile phone vendors claim, they lock us out, because we could potentially harm the hardware. Isn't it their task, just to develop robust hardware and allow us to install any software we want?
This petition would aim for:
- open bootloader by default
- root by default
- warranty for the hardware, no matter which software you used
- free to install custom roms
- robust hardware
I'd like to start a petition and perhaps some public awareness for this issue.
So, if you want to help with anything.... Like writing a petition, a more handy text then this, for example, would be needed.
Discuss.
Installing another O/S on your laptop is not likely to break it, if it does you fix it or take it to a computer shop. A computers warenty normally only covers the junk it came with. There is already a problem with self entitled gits who dont read properly, or make an effort to understand what they are doing who download a WP7 rom, try to put it on a sensation, and expect someone to come running with a new phone. I don't believe they should try to stop people from modifying their devices in any way they want to, but they shouldnt have to cover your fumbling around either. Any modification is rightly done at your own risk.

I agree with this.
One of the major issues with phone ROMs is that you do have the potential to completely brick your phone if you don't know what you're doing. Unrelated hardware failures (i.e. USB port loses power while flashing a new bootloader) may hard brick your phone to a state of complete uselessness.
Having super user access and root on a phone is another issue that the vast majority of end users do not want to have to deal with. UAC is enabled by default on Windows Vista and 7 because it provides robust protection for people who DO NOT know what they are doing. For day to day usage of a computer, users do not need an account with any special access privilege. Even if you do know what you're doing, its still SAFER to be on a non-admin account for day to day computer use.

There are also computers which come without any software, just hardware. If anything goes wrong, like defect harddrive, then it will be replaced, because of warranty.
Mobile phones are very similar to computers nowadays. But there are no decent mobile phones without operating systems available. This is also what I vote vor.

I agree that this problem does exist right now...
But only because the hardware is not robust.
As far I know, (a while ago I informed myself about a few devices) it is not possible to brick Nokia S60 v3 devices. This is because the routine to flash the device is read only and can not be changed. No matter if you lose power during flashing or usb cable loss... You can always flash again. There is NO way to brick the device while flashing.
Apart from the flash routine which is hardly built into the phone, the rest of the phones software can be updated.
That demonstrates that there are no technical limitations to deploy robust hardware.

I also agree that it is saves not to use admin account for everyday use and that it's also a good idea not to have it enabled by default.
On computers you still have the option to legally use your root account. At the other hand with mobile phones this is completely unwanted and you need some kind of hack to do it. This is the difference. And this is what I complain about.
Yeah
I think just like apps there are some absolutely amazing ROMs that run better than the vendor ROMs. I think they should allow those changes to occur whether through a "vendor verified" developer or some kind of authorized ROM download channel through the manufacturer so you can get the style and type you want the most which typically runs much smoother without voiding the warranty. Great idea!
Lmao. Hell no. Carriers and manufacturers will try to start sellings roms like theyre crack. Ringtones anybody? Cmon. Only $3.
Anyways. I think the op doesnt know what hes asking for. What you want is a blank phone and you want the manufacturer to cover hardware no matter what is done with phone. Fair enough. I guess you want them to cover the phone if you burn through all your write cycles in the flash memory used because you have to flash anything you can your digital hands on. You do realize this will cause the price of parts to go up in the long run? And prices upfront will be more because they will calculate losses due to all the warranty claims. Should i keep wondering why insurance prices keep going up? Phones are built much, much different from computers. Pc's are generally modular and a single piece if defective is claimed to oem of that part. Not necessarily hp or dell. Phones usually only have one or two boards in them with all your components. So if you somehow manage to fry your wifi because you thought could improve reception or your bandwidth or whatever with something custom and it doesnt work, that whole board, system or maybe even phone depending on how its built now needs to be replaced.
I dont want to say it, but itis fair for them to not cover your phone if you went above and beyond. True, because we have become digital crackheads we usually become beta testers for their hw/sw but we also have the power of the coin too. You cant fault them if you wanted to improve their bugs/sw. You cant go banging on your drug dealers door either when he sells you some bunk cocaine and you go mix it with drano, just hoping for something and it backfires on you.
I voided my warranty.
Some interesting opinions. If this was made legal there would likely be restrictions placed on what can be changed, and it would likely end up regulated in some way.
The result would be third-party 'illegal' roms and commercially available 'legal' ones.
People like us would likely still be flashing illegal roms with modified clock-speeds etc ; )

Stripping down a phone to its bare minimum

I learned about BOINC for android recently and since I have some old smart phones lying around which are never used I thought why not put them to some use. I could of course directly install BOINC on them and get going but of course if its the only thing that is going to run then it will be a waste of a lot of hardware resources.
As of now I know only very little about rooting and the Linux OS and also my phones are not on the list for most rooting software. I have thought of two approaches to this.
First route is to root, install a very lightweight Android ROM and strip off all system apps/services/etc until I am left with the bare minimum required to run Android. Since I'll probably need to compile the ROM myself I might do some stripping off at the source code level itself if possible/practical.
Second route would be more interesting but I'm not sure if its even possible. This basically entails removing Android entirely and replacing it by a lightweight desktop Linux (such as DSL) with an external keyboard+mouse using the phone as display and processor.
The BOINC is going to run 24x7 with the phones always on charge. The keyboard and mouse will only be attached while installing the software and for checking things are fine once in a while...so I have no issues with them using up the charger slot and Bluetooth.
Which do you think would be the best option in this situation?

Using Blue Yeti Microphone on Android? Please help...

Hello xda devs!
I've just bought a blue yeti microphone.
I want to livestream on Instagram and use it, however my device will not set the microphone to the external microphone.
There are apps such as Open Camera where you can record a video using your microphone as you can set the external microphone option in the settings, however I need a fix so my android device will ALWAYS use external microphone no matter what application is open.
I've literally tried everything.
I've also bought an adaptor which is female USB to headphone jack, however because the blue yeti needs to be powered by 5V, the headphone jack provides insufficient power to even power the yeti.
I've also tried an adaptor for female USB to usb type C. That powers the Yeti perfectly fine, however the problem persists.
It will not pick up the microphone in an external app that isn't "open camera".
I really need all the help I can get please as I'd love to stream and record with my yeti
Thank you
anyone able to help me please
Welcome to scamdroid.
If you want a real computer, camera, recording device, almost anything advanced users want (aka anyone who needs more than a phone to gossip about kim kardashian on and pester and stalk people busy doing important things) you need to buy such a dedicated device. When you begin to realize you are lied to about what it is then realize these are phones catered to people who gossip on phones 24/7 aka people who dont understand ANYTHING but running their mouths (the opposite of anyone educated or attempting to do anything with their life besides watch tv and gab).
Think about it, who made these phones popular? Apple.
Who is dumb enough to buy into apples lies that their computers are the worlds fastest supercomputers with counless customizations and other computers are just beige box shaped calculators and calanders. SJW kids at best.
You are merely experiencing one of hundreds or thousands of ways they sell this crap under lies and rip off schemes.
Keep down this road and you will begin to realize that XDA and Android talk and the 3rd site are all FILLED to the brim with mods and users who are apple kids whos tv told them to buy an android and youll end up like me avoiding these sites for the same reasons you avoid "the sun" "uk mail and any pop celebrity gossip site. Sure you want to see Kim Kardashians butt, but the people who congregate there make u wanna puke.
The answer is this probably isnt possible because scamdroid software is very locked down and unlike the lies they sold the crap on to compete with crApple they are actually locking the devices down MORE and not being more open.
Expect to not be able to read this when one of the fanboi mods gets triggered im telling you how it is with their favoirte -apple- google device.
Also i heard that the OTG cables were made obsolete and they dont work right unless its a direct USB-c one. $$$$$ I wouldnt expect it to work either way, ive got a few plain mic/speaker splitters and 2/3 dont work and if they do you have to plug them in a certain order and still the one that works distorts the line out.
If you really wanna attempt ill tell you how since these other people dont know. Starting basic droid camera you must plug splitter in first, THEN plug mic into mic in side of splitter. Your problem a little different but apprently the device is smart enough to do such extreme things and maybe im exposing a loophole they havent locked down yet :/ . Anyways try the order you plug crap into the system with xD Or better yet, stop using android like its more than a calaculator, or just throw it in the trash so other idiots can't waste your time calling and texting you about useless extending nothing/gossip and oopposite sex trying to leash u with it, or dont; either way just buy a dedicated camera that will work with the mic. Im done with this trendy hipsters "smart" phone crap, Its dumber than most humans and they are dumber than most dogs, so get a dog and give him your android as a chew toy and buy an actual camera and call it a day. remeber google and samsung sell cameras ad own audio companies, they dont want you to NOT buy that. Theyll only lock them down more and these sites will continue to make fake reviews praising them
With all due respect, "HorrorAngel," your response to the inquiry is useless, rude and absolutely wrong. 1) According to the manufacturer (Blue), the Yeti device CAN be used in conjunction with the Android Samsung 9 series phones. 2) The latest round of Samsung 9 series phones include a back-facing 12-megapixel, 4K quality camera, which is BETTER than the professional cameras I had in my network television studio, back in Chicago (ergo, your assertions are utter bunk). 3) I was just in Mexico City, where I watched as a professional television crew used this EXACT set-up (smartphone and Blue Yeti) for a remote, network interview. Do us all a favor, "Horror," and shut up, if you have nothing useful to contribute. As of now, your rant merely comes across as trolling crap. Get a life...

From what I gather (from Blue, the manufacturer), you can power the Yeti by using an adapter and plugging into the USB 3 port. I was given the same information in conversation with techs at Best Buy's "Geek Squad" support. I have just purchased a Samsung 9 Note, with a 12 megapixel camera, for the exact purpose of using this device to broadcast live, streaming television, using the Yeti as my microphone. Regardless of what a troll has ranted, in an earlier comment, I believe this setup with be successful, as others around the 'Net have already written of their successes. Once I have gotten everything set, and made a first test, I plan to report back on this site with my results.
Good luck! :good:

HorrorAngel bro I don't know about cameras but I am a computer engineer and I was horrirized reading your reply.
"scamdroid" is free and open source OS from google so ..... I can't see the scam ^^ 'you can actually download android, make some changes and then call it a ROM (custom android), as you can search "Best android custom roms" on the internet and install them into your phone. Thats why phones use android, its free. Apple btw makes you pay both for the phone and the software, that also means you can't change it. I have both android and iphone, and also have a phone with Ubuntu Touch from Linux, and I would recommend android because of that, the software is open and unlocked (it isnt by default, you can change it with 3 clicks to enter the risky mode. They do that to make people not destroy the phone's software).
Dont cry if android cant do something you want because it is software and if has limits. There are a lot of programmers like me working on making phones simple to understand but seems that even making it essy there are people like you that are simply blind and don't want to listen.
