Please help me decide between Mi2A and Mi2S

Hello to everyone,

I' m thinking of buying Mi2a, but I'm a bit skeptical about the 1GB RAM, as miui v5 takes about 750MB.
Are the free 250MB enough for surfing, gaming etc?

What if, in a future release (say, miui v6) there'll be more need for RAM? Will mi2a be unable to load the new miui?

(more questions are posted here - please check)

Thanks.

Yes, no problem with Ram.

Android (and Linux) freeing ram when it necessary.

It is not a PC with Windows.

And for next MIUI version, Xiaomi make a optimised rom for Mi2A, exactly like the V5.

Thanks, Derek, for your reply.

Saying "an optimized ROM for Mi2A" means that it will be a "cut version" of MIUI (different than a "full" MIUI running at a phone with more RAM (eg Mi2S))?

(my main dilemma is whether to buy Mi2A or Mi2S 32GB)

No exactly the same rom, but optimisation in kernel, code... Mi2A, Mi2/S and Mi3 have a different hardware. Each rom will be optimized for each hardware.

Mi2S is better than Mi2A, off course, but price not the same.

thanks again.
I've a few more things to ask regarding Mi2A and its differences to Mi2S.

1. Regarding video quality, I found out (?) that probably it's the same sensor (8.0MP, f2.0) used for Mi2, Mi2A and Mi2S (16GB) models and that it's a Sony or Samsung one (although non-branded). Can you please confirm that?

2. Watching some videos on youtube/vimeo, I noticed that there's a weird motion lag (seems like an effect :D) and a problem in stabilization (for example, you may check this video, after 3:10).
Is video stabilization a matter of software or does it have to do only with the sensor itself? Because, if it's the software only, then I think that it's not worth getting the Mi2S 32GB (with the new 13.0MP sensor) (and perhaps that explains why eg. iPhone -with the same or worse sensor- shoots more stable videos).

3. I noticed in some videos (like this) that Mi2A screen colors are more "greenish" than the Mi2S'. Is that something that can be fixed (eg brightness, color balance etc)?

Thanks.

1.- Yes,Mi2, Mi2A and Mi2S (16GBs) use the same sensor
2.- "Jello effect" common on most compact digital cameras (cellphones included), if you want to record video AVOID the 32 GBs version of M2S, it has a bug that limits the framerate to 22.75 fps instead of 30 fps, causing crappy motion, (it may be fixed in the future if xiaomi releases the complete source code).

@squallmx,
thanks for your reply.
Unfortunately, I went for the 32GB version a few hours ago. :( I hope it will be fixed in the future.


ps. Apparently, I haven't noticed the "jello effect" in any of the iPhone videos I've seen. Is it a matter of hardware or software?
