How good is extendible RAM feature? - Android Q&A, Help & Troubleshooting

So this new Vivo V21e 5G smartphone with Dimensity 700 chipset has 3GB extendible RAM apart from 8GB internal. Do you think this works like regular RAM?

How does the Xperia S hardware compare to other phones?

Mainly processor wise. Is this the fastest phone on the market currently?
I know the Xperia S is using a 1.5ghz dual core snapdragon CPU but is it as fast as the processor used in the Galaxy S2?
Memory and most other specs seem similar to all other new phones.
Although I did see recently that in a benchmark test it was quicker than the Galaxy Nexus for most if not all applications.
Just wondering how this phone will hold up after a year.

First year is OK. Arc came where they were dual cores and other stuff and it will even stay longer because phone's usability differs from person to another.
For what this phone is, it pretty good to me and what I have seen and after ICS hits this phone the true power will come out.
Very few applications are even designed/optimized for multi-core use, let alone quad-core.
While the lack of a quad-core will turn away most measurebators who want to buy the latest, glitziest quad-core model, from a software perspective there isn't much out there that will benefit from the extra 2 cores out yet for the next 2 years or so.
I'm a bit bummed about the 14.4 mbs d/l speed and the pathetic 2.1 bluetooth profile. They could have at least done 21mbs and Bt 3.0
Is it true this phone has 2gb RAM also?
I just checked my phone memory and it has 1.78gb free.
It's different from internal storage which I have 25.5gb free.

Hmm!
There is 1 partion for internal system storage, and it is about 2Gb, other partition we known as sdcard, ~ 28 Gb.
So i dont think the phone has 2 Gb ram!

Just like with PCs, there's a difference between internal storage and RAM.
AFAIK, the Xperia S has 512 MB RAM, of which about 340MB is available for applications to use while they are running. Right now, with the optimizations I have in place, I get about 370MB free RAM, which is a HUGE boost from the 100-140 I had on the Arc.

This is incorrect Xperia S has 1gb RAM. The 2GB partition is for app installs and the ~28gb is your internal sdcard storage. The 2gb and 28gb internal storage is just partitions off of the 32gb internal flash storage.

Yes, you may be right about the 1GB - I currently see 178MB used, 453MB free, so the rest would be used by the OS.
Still a massive boost over the Arc.

No this phone does not have the fastest CPU this is only downside to Xperia S. They released an excellent phone with last year CPU. The CPU Sony has is snapdragon scorpion or S3 while most phones being released in 2012 will have a snapdragon Krait or S4. The S4 actually performs faster than a Nvidia Tegra 3 quad core CPU which the HTC One X will have. If Sony released this phone with an S4 it would have best the ultimate android device IMO. However the Xperia S is still a good device that will last you a year easily and it beats a galaxy nexus which is the premium android phone right now as far as CPU.
Phones with 1gb of ram will have 256mb for dalvik virtual machine, so only 744 mb ram availble, and ram for system cache is about 200mb, that why you see free ram is about 400 mb.

Need a 9.7" tablet

Hi guys, I wanted a 9.7" tablet but not sure what to go for so would appreciate your help. This would be my first ever tablet!
I want something to read books on and play game/surf web/watch youtube etc, budget is $220 USD. I've done some research and have narrowed it down too (prices I got online added next to each tablet):
Ampe A90 $210
(has 1.2Ghz A10 CPU; 1GB DDR3 Ram and 16GB internal storage, plus 7000mAh battery)
ONDA VI40 $220
(has 1.5Ghz A10 CPU; 1GB DDR3 Ram and 16GB internal storage, plus 5000mAh battery)
ICOO D90w $218
(has 1.2Ghz A10 CPU; 1GB DDR3 Ram and 16GB internal storage, plus 5000mAh battery)
Cube u9gt2 $209
(has 1.2Ghz Rockchip CPU; 1GB DDR3 Ram and 8GB internal storage, plus 8000mAh battery)
Ployer Momo11 $200
(has 1.5Ghz A10 CPU; 1GB DDR3 Ram and 16GB internal storage, plus 7800mAh battery)
Given that there prices are so close which would you go for
If you are looking for something with dev support, meaning custom ROMs, you can get an HP Touchpad for this price if you look around online. It has a 1.2ghz Dual Core Snapdragon S3, 1GB of RAM and around a 6000mAh battery.
surely the Chinese tablets would have dev support and are better specs wise?
The Ampe A90 seems better though as it has extra 8GB internal storage but this has a Rock CPU compared to an A10. Not sure if there is a difference as the speeds seem the same.
Anyone else?
Im thinking its either the Onda Vi40 Elite, Cube U9GT2 or the Ampe.
Leaning towards the Onda.
Ended up getting the vi40 for £153 from the UK. Looking forward to it.
Not on your list, but I highly recommend cchecking out the Advent Vega.

Redmi note 4 3gb 32gb vs Redmi Note 4 4gb 64gb

I want to know how much space is left on the ram and rom of these two variants. I am not a gamer but I use a lot of apps and spend most times on my phone.
The 32GB version is more likely to be left with about 28GB of available space. As for arm, the features of the MIUI are known: arm is very large and has very little memory available. I suggest you buy 4GB of ram. Of course, the most important thing is not to buy the x20 processor version of the mediatek. Otherwise you'll regret it

Mecool KM8 P 1gb/8gb ram upgrade?

Hello,
The box i'm talking about, has 1gb of ram, which i'd like to expand. On the internet, i could get hands on a 2gb ddr3 ram chip, similar to the ram chips on the board. On the board are 2 chips ddr3 each 512Mb. About 200Mb is used for the gpu i think. This leaves 800Mb for the os. Now i have a chinese heatgun with small nozzle. It can go to 1000degrees celsius(the display shows this). Now my question is how do i install the extra ram chip without destroying the board?
Grtz,
Mark-1978

Realme XT uses a lot of RAM?

I bought the 8gb RAM version of realme xt, but only 4.28gb is available out of 8gb.
Is this a issue or the color OS is really this heavy?
How much ram is consumed for 4gb ram version?
Unused RAM = wasted RAM, you should be happy it's being used.

I agree with you. I have the 6GB version and usally about ~2,4GB of free RAM. No problems with multi tasking
