SGS can detect 5 different points at the same time

messing around with 2.2 roms on samfirmwares.com and found this in JP2, along with terminal access, how can we use this to our advantage

And what is new in your post?

Apparently Atmel chipsets can support up to 16.. So possibly more can be supported..
But yes, we already know the device supports multi-touch, and supports it properly (unlike the majority of phones which use synaptics still)

That's great! How is the sensitivity? Does it require that 5 fingers are placed on the screen at exact the same time.... I mean, only the worlds best pianists can do thát Ah, here's an idea: create an exercise tool for pianists, guitar players etc.

lol, 16 touchpoints? That's really useful functionality. Multitouching with all toes and fingers at the same time.. yes, I can envision a very interesting app.

God that was funny.

I would like to see a photo of a galaxy S with sixteen fingers/toes/stylus on it at the same time.

I can produce 11 points without the use of my toes or tongue.

That has nothing todo with Froyo...
I have JM5 on it and can also touch with 5 fingers.. I never found any touch app, which supports >5 fingers..
And if you have used the search function, you would find another thread about this..

Impressive I never thought of a limit since typically every multitouch input I use is 2 fingered.

I can produce 21 points if only would it support that much

But what's new about this every SGS ROM can handle up to 5 points
hope there will be an app to get 10 points, just for showoff can't think of something usefull with 10 touches at the same time...

Very responsive and precise !!
Look at a comparisson with the desire:

16 points would be helpful for devices similar to Microsoft surface (not so useful for mobiles probably)

I believe the hardware technically supports "unlimited touchpoints", but somehow (can't recall where I got it from) I've gotten the idea that every added point comes with a penalty in update frequency.
A 5 point limit makes perfect sense for the 4" screensize.

That makes sense. All I know is that it's designed for 16 max (which is a magic binary number). But i would imagine that you are correct..

You're correct, the hardware supports unlimited multi-touch, but I think android is limited atm to only 5 points. I've seen 3 multi-touch apps that go up to 5 points, but not more than that. Multitouch vis. test was recently updated to check for more than 2 points, but it only goes up to 5 now as well.

How is the Custom Rom support for the Tab 8.4?

So I've been giving real consideration to picking up the 8.4 Tab, that screen is very nice. But like many I've been waiting on Google to announce the rumored Nexus 8 or 9. I have a Nexus 7 '12 I'm ready to replace. If I get the Tab, rooting and a custom rom is a given for me. I'm wondering how many roms support it though? The main roms I use are Cyanogenmod, Carbon, and Liquidsmooth. What roms are you guys using and what's been your experience rooting this device?
Any input would be appreciated fellas so thanks in advance.

Forget about custom roms.

It's an Exynos chipset so of course the options are limited and dev support will remain nearly zero. The last Samsung device with Exynos to experience decent dev support was the Note 2 a couple years back.
Samsung's indifference/hostility to devs makes it unlikely to change. See the International Note 3 for example.

These are the kinds of things you can't easily research before purchasing a device. I lived under the delusion that Android = infinitely hackable. Didn't know it varied per device to such an extent.
I did try CM11 and it was fairly stable (until I tried to put the governor in performance mode, lol). Sadly, the more I learn about this tablet, the less appealing it is And most of that seems to stem from Exynos. Something to watch out for henceforth, I suppose.
I think I might chill on the whole tablet front until the next Nexus tablet.

Actually, rule of thumb if you're interested in custom roms - Avoid Samsung and just stick to the other big three.

I was trying to wait on the new Nexus tablet since I had the 7 from 2012 but got impatient. Actually just got the Tab Pro 8.4 to see how it is. It's cool so far, not sure if I'll keep it yet. Thanks for your thoughts.

After seeing this post I tried the performance governed and don't see any issues. Not that I'm asking for bug reports but still sorry you had issues.
as far as all the hating on the exynos soc, its really not any different then the other soc's out there as far as porting goes. There is a ton of source out there for the 5420 and its even been updated a couple times.
Sure hate on Companies and all that deserve it, but in this case Samsung has given plenty of support, more then even I expected and they deserve the proper credit for that.
Edit, don't mean to single out this single post, it is geared more towards the thread in general.

because of missing kernel support or missing gpu support?

We've already got a working CM11 for 8.4, looks like there could be 10.5 CM11 just round the corner. A number of rooted and debloated stock roms. There are devs working on AOSP and LINARO. We have a kernel for stock and CM11 and the device is only a few months old, what more do you guys expect in such a short time? The Exynos development will come, be patient. ?

If _all_ based on _open source_, only a full re-compile on a fast machine would necessary.
So, it is not open source at all?

"Android O - 8.0" PossIble for Zenfone 2?

Hello everyone, it is possible to receive custom ROM "Android O" for our Zenfone 2 ???

O was just announced, we're going to have to wait a little longer before we can know if it's possible, and a lot longer before it's actually built.

I wouldn't say completely. Google is laying out minimum hardware requirements for stuff like audio, vr and ar which our old phone may not mean.
But do I have confidence that our devs will make everything else work? Yes, completely. Although it's gonna take a long time. I will be elated if N hits stable.

Since the question of this topic can't really be answered, someone knows how long statistically can a device be supported by custom roms? I mean maybe Android Z is too far fetched, but android P for example?

well my current daily driver is an AOKP 7.1.1 Nougat on my Zenfone Max ZC550KL with no bugs so we can hope the same for O when Lineage OS releases its own version.

Hardware is the least of our problems, considering the one in Zenfone 2 (ZE551ML for example) is more than adequate.
Google making up it's own hardware requirements is nothing more than pandering to the idea of planned obsolescence to be honest so that they can sell newest phones.
I think that if the devs can get their hands on viable drivers that support the hardware in our devices and are compatible with Android 8, then technically, it shouldn't be an issue.
For Oreo, google would be pushing certain updates (fixes, etc.) not as a standalone feature, but something that would work in the same way as Windows and MacOS system updates do within the same OS version.
We know Windows updates usually work on a variety of hardware if the Windows as an OS is the same... the only thing that you also need are drivers to properly support the hardware in question (which can be difficult if the hardware is ancient, but I doubt this would apply to Zenfone 2) - this especially applies to upgrading from say Windows 7 to Windows 10 for example as some features like a microphone might stop working if the hardware in question was say from 10 years ago. Works on say Windows 7 for example because Vista drivers were made for the hardware in question which were compatible with Windows 7 to a point, but for Windows 10, compatibility between drivers for older Windows was not maintained and new drivers need to be written.
So, large OS replacement would likely depend on hardware drivers support and updating the OS sequentially shouldn't be an issue if the drivers exist - if they don't... then it's a problem.
Manufacturers tend to stop supporting hardware after a certain time... OEM's are even worse.
If we can find drivers independently from a company that produced it, then it might be possible to find more recent drivers that work.
In case of GPU's (or any other hardware inside your PC), you wouldn't rely on the OEM for drivers. You'd go to AMD's or Nvidia's websites to download latest drivers.

Why is there no Lineage ROM for our device?

i know i can try to build it myself, but this isnt a demanding question... im simply asking like why is it that other devices even have unofficial builds but we dont?? is there some king of limitation that prevents it to be built fir pixel 3 xl???

The only time I have turned to Lineage to to overcome the shortcomings of an adulterated Android.
Samsung, OnePlus, are the only 2 that come to mind.
Rooted Pure Android from Google is pretty much perfrect for me and I cant think of enough improvements that Linage could offer to make it my daily driver.

Yet, without it, there would be far less ROMs on XDA

LineageOS seems pretty great to me when I use it on devices that don't come with relatively stock Android. Don't see the need for it on Pixels since it already offers pretty much stock Android, unless you want to run without Google apps or something or you want support after Google stops supporting it(end of 2021). Don't even run twrp now. Just patch the boot.img monthly.

Right, Lineage is the "other" Android experience, most of the ROMs on XDA are Lineage based and there's nothing wrong with that, lol

Cheap Phone For LineageOS

Hello,
I was looking for recommendations on a cheap phone to get started with trying out custom OS's and maybe serving as a backup phone. I found a Blu Advance L5 on Amazon for ~$40, but it looks like it isn't compatible with LineageOS and some of the other builds. Not looking for a daily driver, just something to test things out with. Thanks!

I'd recommend looking for a used Google Pixel phone. The 4 and 5 series still has a lot of custom ROM support, including LineageOS. (Google has ended support for the pre-4 models, so I'd stay away from those. Some developers may still be able to eke out some support for them still, but it's not guaranteed.)

Other than what @MJPollard said, you can check also this:

And make sure it is common enough, so support doesn't stop suddenly:

Thank you both. Any thoughts on something like a Nokia 6.1 or Motorola phones (i.e. something sub $100)?

IMHO, anything that's sub-$100 probably isn't going to be supported for very long. You could get one of those phones, only to find out that it'll never go beyond Android 12 (LineageOS 19.1), or might even be stuck on earlier versions due to the lack of any further software support for the hardware (i.e. kernel and driver updates, which are essential). That's why phones like the Pixel are often good choices, as they'll usually be supported with new Android versions (both officially and unofficially) for a lot longer than the el-cheapos. You may have to pay a few dollars more, but you'll be better off in the long run. (Personally, I've had OnePlus phones for the last few years. First the 3T, then the 7 Pro, and now the 9 Pro. Probably not a choice for you as you're looking for something cost-effective, but OnePlus generally has an excellent shelf life even after official support ends... at least, it did until the OnePlus 10 series, but that's a subject for a different thread. )
