Hi,
I'm trying to get some understanding of the VZ version of this tab and what it would take to build a custom rom for it.
Been playing with custom roms going all the way back to a htc g1 so I'm pretty familiar with the processes involved from the user side of things.
First a couple clarifying questions specifically about the VZ tab, is this one called 6815 or is it a 6800/6810?
If it is a 6815 as I'm assuming has there hasn't been any custom rom work done up to now? I wasn't able to find any.
What would it take to get the CM team of one of the other ****-hot dev teams to develop for this tab? Is it simply a lack of access to the hardware?
If it is lack of hardware perhaps we could join together as a community and raise some funds to support the purchase of a dedicated dev tablet. Heck I might be willing to donate my own for a time.
Thanks for any ideas / answers.

Verizon SCH-i815 the 6800 and 6810 are for the rest of the world.
The Verizon version incorporates its 4G LTE and an infrared blaster.
I would also be happy to contribute to any development on this tablet. Love the thing, but I know the potential of it with development.

Anyways, how are phones like these, does anyone know better sites?

I assume these are just chinese knockoff phones. Most seem to model off the s3 but....how are the phones? If there specs don't lie, they seem like very nice pieces of tech for the price! I have my anciet evo 4g because I misplaced my s2 and don't want to pay $600 for a new phone.
If these phones are indeed half way decent, what do I need to look for to obtain a phone compatible with sprint? From what I see nothing advertises wimax, which, I would be slightly sad to lose, but if everything else works on these things just find, I won't mind losing the wimax.
If this topic has been covered, or you have a simple link to address, please just post the link and don't tell me to look harder. I have looked and nothing seemed to fit for a good answer.
Thank you for the help!
Well, I have found this phone so far
http://android-sale.com/star-lt29i-4-5-inch-qhd-1ghz-dual-core-mt6577-5mp-camera-android-phone.html
and it looks like it's the best from what I've poked around....Would this work with Sprint? I will go in there soon and ask their policy on these kinds of phones. It says it supports WCDMA, and I think sprint uses CDMA, and I have no idea how the two related and the internet doesn't seem to help on informing me if sprint could use the device.
Lastly, where would I go for help/tools to root and ROM the device?I assume something like superone click may work, but if I do end up getting one of these phones, I'll ask more about rooting and whatnot in the android section.
Personally, I think they're poor value even if you but one from a maker who isn't lying about the hardware specs.
You're almost certainly not going to be getting any kind of custom development - the sources are most likely not even there to work from and the devices aren't popular enough for it to happen.
You can get something similar when buying a legitimate phone that's popular overseas - development is possible there, but you'd have to look into it.
The lack of support and potential to get something other than puts me off buying such a device - you know how you can buy an SD card that says "32Gb" on it and it's only like 5Mb or whatever ? Think about that - your phone might say it has 32Gb internal memory but you might really have 2Gb or less and you might get 254 or 512 RAM. You might be able to root, might not.
As for network compatibility, just look up what bands Sprint uses, compare, and hope the information is correct.
You might find a "good" clone with good reviews, but you lose the "value" that is development and support. What is that worth in dollars ?
Personally, I'd rather just get a used S2 or something. You can get a used S3 for $400-ish if you're lucky, S2 is $200-ish, I think. I'd go for something like that - something that was popular and had good development and support in its day and likely continues to have some even now. I can't put a cash value on that.

Do you have any suggestions on a good place to get a used s2? Actually, i may get my old s2 back soon.... Which would be lovely and solve my issues. I am curious though. Maybe later this year I will check some of the knockoff phones, just to test them and review them. I see your point, and it was my concern as well. I've always disliked phone companies and their support, and I assumed I could easily get some working rom and root, but tinkering with experimental builds for daily use is enough risk for me already. Adding a phone with a possibility to fail on me at any moment, probably isn't a good idea. These devices have too little real info sadly

The thing is, even if Samsung isn't giving updates, they've still released enough of their source for people to work with to develop custom ROMs. The companies that sell the clone phones and such don't do this, so making a custom ROM isn't possible. Developers tend to like to either work on projects for their own devices, or ones that will get a large audience for their work, so even if there was material to work from, these wouldn't be very attractive targets for development. Most US phone customers still get their phones from their service providers, for better or worse.
Anyway - eBay, Craigslist, or one of hose sites for specifically selling mobile devices. I think you said you're with Sprint? You have to make sure the ESN is good in that case, is the biggest concern. I've never had to do this since I'm with T-Mobile (uses SIM cards, not ESN), but I'm sure there's advice out there on how to avoid being scammed.

Firstly, I'm NOT a Developer - I want to make that very clear
I have been trying to get data/info about what ever happened to the Original Samsung Galaxy S4 'TouchWiz'
Camera feature/ability to be able to 'Simultaneously' record videos (not talking about taking pictures here)
with both the front and back cameras on the phone.
This question has been asked before by a very very very small number of people on the net including in XDA
developers forums, However these questions only have been asked on forums relating to NEXUS phones/devices.
When i originally bought my S4 (second hand) i used the recording feature, i absolutely love it, i think it it brilliant,
it is one of the reasons why the S4 has such appeal for me.
I later upgraded to CyanogenMod, because of privacy concerns relating to Samsungs Involvement with the NSA over
their KNOX security.
The OS seemed fine to me, but this security concern was the basis of WHY i moved over to CyanogenMod.
Then i found out, that CyanogenMod does NOT Support the Dual Camera feature.
I contacted Samsung, and they told me that the Camera app was not really an app at all, but was in fact part of the OS itself.
But remember, the Genuine Samsung Galaxy is actually model number GT-i9500, which uses the Exynos Chip, unlike the Samsung Galaxy S4
variant known as the S4 LTE GT-i9505, which uses the Qualcom Chipset.
It has also been said by some XDA developers, that Samsungs 'TouchWiz' is not Open Source, it is Closed Source.
Well belonging to the company, this is no surprise, I'll also bet that it is probably Patented as well.
I say, so what ?, CyanogenMod does NOT need the original samsung 'TouchWiz' code, it only needs to know the HardwareSpecs of the Qualcom
Chip, then programming/developing can begin.
The S4 is already Superceeded by the S5 (and any possible variant(s) of that), i feel that the GT-i9505 is getting left out of the picture.
Are there any answers to this mystery ???

What mystery? That Cyanogen doesn't offer the ability to record with the front and back cameras at the same time?
That's not a mystery. It's that only 1 person out of a million would ever want to do that so no one is devoting their development time to integrating that feature.

I'm afraid I'm not completely sure i know what you mean?
Do you mean that there would only be 1 Developer out of a million who would use this feature, and therefore no support would be actioned for this ?
OR do you mean that in your opinion there are hardly any people who would own a phone like the S4 that would want to use this feature.
Why would anyone *NOT* want to do this. It's fun for one thing.
Maybe I've made a mistake but, i thought that one of the things that XDA devs were all about, was trying to fix or patch areas on OS's
where the mainstream had overlooked, and especially about importing and bringing new features about to free OS's such as CyanogenMod.
Could you please clarify i bit more carefully about, this.

You are pretty close minded even though I don't use that feature myself.
V-bloggers love using that feature.
But I do agree with you. AOSP is suppose to provide a clean experience

The insults aren't needed.
I stated a fact. There is not enough desire for this feature for developers to devote time to coding it instead of coding something else that is more heavily requested.
If there were a strong desire for it developers would be looking to fill that need.
But there are alternate methods to getting this feature...like using touchwiz. So there aren't many devs who want to spend time coding a little used feature that is already available elsewhere. Especially one they don't intend to use themselves, and not when there are more popular mods that people are asking for in droves like gps fixes and updated kernels and theme manager fixes.
Keep insulting me if you like for telling it like it is. But this is the simple reason why this feature hasnt been widely developed.
If the OP really wants to do this on an AOSP rom, he can learn how to develop. Many many many people here learned how to code specifically to create a feature they wanted.

I didn't really back him up or said you were an insult.
I said that AOSP rooms should be free of non Google modifications.
But I am just telling you again that there are probably more than a million in one desiring for that feature because some people like to v-blog

OK, Fine your point is now made.
But just remember, at least on the Samsung series of phones, the S1, S2, and S3 did NOT have this feature, the S4 was the first phone by Samsung to have this feature, and the S5 is now officially the 'Flag Ship' phone for Samsung.
As with continued development of multi-media standards, i.e. 4K for a start now available on the Sony Experia Z2 phone for one,
the demand for ever increasing video recording features and abilities will continue to increase, so it would not really surprise me, if later
on this feature were to start appearing in later makes & models of phones down the line.
You really have to consider what % of people will even know or find out about free AOSP OS's like CyanogenMod, for one thing,
and even then what % of those people will even upgrade to such OS's.
The demand for Dual Camera Video Recording will probably go up and up amongst the general populace of phone users.
Right now the demands are other things, things like theme development, bug fixes, etc.
Having ones 'foot-in-the-door-now' so to speak, could be a worth while investment for later on.
Sure the demand NOW is very little, but if devs wait till later on to do this, then when the demands get bigger (presumably with newer
models of phones), devs will be flooded with all sorts of bugs to have to sort out on all the different OS types and versions,
- while the demand is great -, thats a lot of pressure on devs, which would also slow down development in other areas.
I think now, i have made my point. While this does sound purely like an argument just so i can gain something for myself - it's for ALL other people. I dont and cannot claim to represent what people in the world who own phones want. But logic sais that if i want this, then there are lots of people in the world who want this, just because XDA devs have not heard of such people, does not mean that they dont exist.
Besides I'm talking about being able to record video with 2 cameras at the same time, is that really such a grand feat ?,
Hell the XPrivacy program i use that XDA devs made was a Major Feat, Dual Camera support cant be THAT difficult to implement.
As for your other comments:
"But there are alternate methods to getting this feature...like using touchwiz." - well i think i already explained why i went to CyanogenMod in
the first place.
"If the OP really wants to do this on an AOSP rom, he can learn how to develop. Many many many people here learned how to code specifically to create a feature they wanted.[/QUOTE]" - Actually when i was a kid i programmed BASIC, but i have brain damage due to seizures affecting
my long and short term memory, so sorry, your claim that any OP can program is incorrect.
My Point Made
Your point made? I still don't even know what your point is.
Look, I get that this feature is important to you. But that does not mean that it's important to a large percentage of everyone else.
The Samsung AirView features are far more requested to be ported to AOSP roms but even then the demand is so small compared to the demand for things like floating windows, hover notifications, theming fixes, Knox workarounds, etc. No devs even want to tackle the AirView features, which get asked about at least once a week on the various S4 forums, because there isn't enough demand. And there's even less demand for simultaneous duel camera use.
In the years I've been here this is the first time I've ever heard of a request for simultaneous duel camera use. And I read nearly every post here nearly every day. So while I appreciate that this feature is something that's really important to you, it's just not in high demand.
And there is zero incentive to develop it now before it becomes high demand later. There's no money to be made in rom modding. If people suddenly want this feature down the road it'll get developed then. There is no early investment incentive in this. Phone modding is a hobby. Like fishing or model trains. We do it for fun, not for money.
As for the difficulty of simultaneous duel camera use...yes, it could be THAT hard to develop. It's not just an app. Something like this that controls 2 pieces of hardware at once would have to be coded into the kernel. And while kernel tweaking is fairly common, completely new kernel features are scarce because it's a very limited number of people who can do it. (And the stock kernel is closed source so it's not like the code can just be lifted from the Samsung version)
Second, once you had the ability to do it in the kernel you'd need an app that could take advantage of the support. You couldn't use the stock camera. You'd need something new. So that's a second layer of development. So this isn't a quick 1 hour project. It's a lot of hours that someone would have to put into it, for something that isn't being asked for very much.
This is the reason it's not being done yet. Don't be mad at me for giving you the honest answer.

Well i think that everything i said above are _VALID POINTS_ points i would have though would have been important enough for XDA devs to consider.
It seems to me that there simply is TOO MUCH demand on the XDA devs in general.
"There's no money to be made in rom modding."
As for 'INVESTMENTS' - I did _NOT_ mention business or money making at all - I meant your investment in coding/programming, your time put into work.
"There is no early investment incentive in this. Phone modding is a hobby. Like fishing or model trains. We do it for fun, not for money."
Well, i guess i will have to turn to people i CAN pay money to, to make it more 'worthwhile' for minority's such as myself, if not a dev.

Nothing wrong with that! Try to find a group of likeminded people who want this on AOSP and put a bounty together to offer to a developer.
