Hy,I would like to know more about the android versions and custom roms.
1)Why some devices do not support new versions of Android?
Why is not working as a PC operating system? For example when windows7 appeared most of the PCs could install windows 7.
2) Why is possible using a custom rom like cyanogen to update to a newer version of android although this version is not released by the producer. Ex. install ics on galaxy S.
3) Using a custom ROM can update a device from the first version of Android to the latest one?
Thank you for your help.

To answer your questions as best I can...
1. Most phones can support almost any version of android. It all has to do with their chipset.
2. When a custom ROM is created, it is based on a certain version of the OS. It is custom because it is modded by developers to be compatible with different devices.
3. Yes. This is true depending on, again, the device and the developers. For me, I have had many devices that were on froyo 2.2. And would not get an OTA update. Whereas a custom ROM could kick it up to gingerbread 2.3 or ice cream sandwich 4.0.
I hope this helps!

1. the problem is with your carrier or manufacturer usually. some push updates through fast, others test updates before letting users update. also older phones get forgotten. a new phone will be more likely to get updated than an old one. they want you to buy a new one
2 and 3 what i337 said. i would just add that using a rom bypasses the problem in #1
Also one of the big issues are the drivers. The open source drivers work but don't use the hardware to the fullest. Also non of the OEM related apps and stuff work on AOSP roms. Then you have app compatibility issues with AOSP roms as well.

Hey guys
first thx for helping, im thinking about buying the Experia Arc with the androod 2.3 installed but im kinda afraid cuz very soon the android 3 will come out so i want to ask ya is it possible to update the 2.3 to the new version ?
cheers
3.0 is not available for phones, it's tablet only. 3.1 (Ice Cream Sandwich) was only announced today, and won't be released until October at the earliest, so no one is going to have any information on porting it to any device at this point.

Actually 3.1 is an update to Honeycomb which is soon to be released to the Xoom. Ice Cream Sandwich is 2.4 which includes mixed features from Honeycomb and Gingerbread. Also Honeycomb has been ported to some devices. I got one to work on the HTC Hero, although every port lacks almost every feature because it is from the SDK image and not source as source has yet to be released.

thanks for your replays,
but still whenever the new version come out will i be able to update my Os ? used to have X1 before and to put an official 6.5 was a pain so is it the same with android ? or i can always update to the latest version
thanks again
The Cm7 development tree is gradually incorporating ice cream/honeycomb features into 2.3.4 with "tablet tweaks" while we're all waiting for aosp. Not very many options currently exist besides moving the status bar to the bottom, but the soft buttons are being merged now and most devices currently have 3.0 ports that just need the actual source to be released now to get things like phone.apk and wifi drivers working. I wouldn't be surprised to see a rom dev have a fully working port for the arc the day after google releases the 3.0/2.4 aosp, so I would base your buying decision on the performance of the arc compared to other 2.3 devices currently out or being released this summer.

Upgrading the Android OS is always going to be 'hard' if it is not an official upgrade by the distributors of your given phone. If you are rooted, which for some phones is a difficult process, you can upgrade, albeit that it's not official for your phone.

From what Sony is announcing you will get the update to whichever version of Android is available past version 2.3 faster than they have released updates in the past. If this is true don't worry so much about the version of Android you're running since 2.3 is actually a very much complete package (in my opinion) and you can also say the same for version 2.2. Anything 2.1 and below is not even worth considering.
I'm considering buying a phone that I've always wanted, however it's running an 'ancient' Android OS, Froyo. There are currently ICS-custom roms for the phone, but my question is, if I update from 2.2 Froyo to the 4.0 ICS rom, will I be able to access, download, and use 4.0 applications for it? Or are the custom roms just there to make the phone look up-to-date?
Thanks in advanced for any replies

When you install a custom ROM, it updates your phone to the OS that the ROM is based on.
So yes, when you install a 4.0 ROM you would be able to run 4.0 apps because you would be running Android 4.0

How do i upgrade android version on a rooted device?
I am currently using Samsung Galaxy Tab 2 7.0 GT-P3100 and running on 4.1.2 Jelly Bean..
How do i upgrade it to 4.2.2 or maybe higher (4.3 maybe?)
Can i do it without un-rooting?
Whats the newest available android version for my device? Well, i know the latest version is 4.4 Kit Kat...
Can someone kindly explain to me step by step on how to do it..thanks
Help anyone?
Generally speaking, you may choose one of the following:
1) To upgrade to an official ROM. You'll likely lose root by this process, because it replaces the /system directory, where the root files are living, with a new one. Some rooting packages may internally try to preserve themselves to survive upgrades, but it depends on many factors and isn't always reliable.
2) To upgrade to a Custom ROM. Using custom ROMs is not for everybody. They have some advantages - obviously they are available in newer versions than the official ones, may contain additional features (for example, they are automatically rooted), may have better support (more frequent updates etc.) than the official ones etc. However, they may also have disadvantages: They possibly don't exist for every device, they may need special handling on devices with locked bootloaders (but for most of them, it's possible to run custom ROMS even in this case), the process of flashing Custom ROM may be a bit complex for unexperienced user in comparison with flashing stock ROM with help of the official PC utility etc.
I'm sorry that I'm not specific about your device, but I don't have particular experience with it. I hope that you'll find at least something generally usable for you and based on that, you may find more specific information by yourself.

Hello, I have a samsung Y tv with its stock rom with android 2.3.6. I found a custom rom with android 4.2.2 and I installed it hoping that I could download the apps that I could not download with the 2.3.6 version, but I could not anyways. I imagine that its not a problem with the android, but one with the hardware, am I right?

i assume the play store is saying your device is not compatible with the apps you want?
it could be hardware, but most likely software.
its difficult to some times not possible to make apps work with every version of android ever made, so there is usually a cut off as to how far back it will work. this information is frequently posted with the app, but not always. look near the bottom.
usually will say something like "requires android 4.4 or newer" but the backwards compatibility varies from app to app. one might be compatible back to 3.0 where another might be only 5.0 and up.
I'm currently looking to get a new phone to replace my OnePlus One. I am strongly against bloatware and have become very discontent with the lack of continued software support offered by most (all?) manufacturers, including OnePlus and Google.
I am entirely new to rooting, unlocking, or flashing custom ROMs to my phone. However, I want to explore what options are available for using a ROM other than the pre-installed one and keeping it up-to-date myself.
First, one thing I don't understand very well at the moment is: what is required for a particular phone to have different ROMs available for it? For example, if I were to buy a used Samsung Galaxy S6 edge and I wanted to run stock android on it, what is necessary for that ROM to exist? Are there generally a lot of phone/model specific modifications that must be made to the Android source in order for it to run/be usable on that particular phone? Does it depend, at least in part, on which phone-specific features one wants to be usable (I read that the edge on Galaxy Edge phones will not work)?
Beyond stock android, are distributions such as LineageOS effectively stock android + their own suite of additions? Would a LineageOS ROM offer better/worse device-specific support than a stock android ROM for the same device?
Second, if I wanted to install a ROM on some phone and keep it updated, how would the update process work? Would I have to wipe the phone every time I install an update, or can updates be applied incrementally?
Finally, if I want to run a stable ROM on my daily phone without having to worry much about running into issues, what are the common options?
Thank you so much for the help!

Yes, ROMs and recoveries must be built specifically for each model number, they are all different.
Yes, if you flash a custom ROM and then the developer of that ROM releases an update to his ROM you flash that update without wiping but if you switch to a completely different ROM you have to wipe before flashing it.
As for options of which ROM to use, you'll have to experiment and try them to find one that suits your likes and dislikes. What I consider the best option may not be the best option for you. To each their own, as they say.

My goal is to find a stable ROM that will continue to receive security updates and bug fixes even once official manufacturer/vendor support has been dropped. Continuous software updates (i.e. to newer versions of Android) would be great too. I suppose this will depend on the hardware I'm wishing to use. Being new to xda, I've looked around and seen people posting various ROMs for various devices on the forums. But I'm not sure how reliable, stable, or even trustworthy they are. How do I evaluate ROMs posted on xda for those qualities?
LineageOS is one that clearly stands out and offers official support for many devices. Thus, it currently seems like a strong contender for my purposes. But I'm wondering if there are other distributions you would recommend that are on par with, or at least in the same tier as, LineageOS that would serve my purposes?
For what it's worth, being a developer, I would also like to give back and contribute to the community for the device I end up getting.
I'm not sure if they offer a ROM for your device, but Dirty Unicorns might be one to check out
