You've jumped into this thread a little too late to be giving advise.

1. Miui kills or suspends apps frequently making multitasking difficult which is a top complaint of the phone so the stock rom may have an even more aggressive oom vs CM11.
2. Low free memory does not mean a bloated rom, it could be that the OS does more prefetching or caching. I have more problems running tasks on the 1S compared to an old 512Mb phone. Rom 37.0 improve the amount of free memory on the 1S to around 350Mb but had little effect on the problems with multitasking (low ram issue), which makes me think that Xiaomi doesn't know the root cause of the problem.
3. "there's no universal settings that can suit everyone's usage" - that should be a joke since low memory issues is a top complaint of the 1S which led to the fix in version 43.

The 1S is a dual standby sim like most (almost all?) dual sim phones. That means when one sim is on a voice call/sms, the other sim will be inactive. So the other sim will either get an out of network error when someone is calling or their call will be routed to voicemail.

Has anyone noticed a decrease in battery life or an improvement on the heating issue on v43.0? I read that the new rom was supposed to work on those problems but I did not notice any improvement.

Yes. Its like having one old telecom malaysia phone with an (cable) handset extension (before the days of cellphones) so one one person can use the phone at anytime. You can set up call forwarding on the unused sim to get calls through.

Why don't you google, ask a shop assistant or post on the miui forum? You've been given explanations several times in this thread, can't make it any simpler.

The cover is really easy to open.
Just stand the phone on its head. Jam one fingernail using a finger from the right hand into the notch on the cover and press the right thumb on the mi logo, then pry it open using your fingernail. The cover will be lifted from the corner nearest to the notch and you can just continue opening it.

You can do it using the usb notch and pressing the mi logo again as the fulcrum but the pre-cut notch near the corner is a little easier.

Theres a teardown on the official forums showing the 8228 cpu. The other teardown showing 8628 was for the China tdma model.

41.1 and 43 is practically the same. 41.1 was released first in India while 43 is the global version.

CM11 is still has some minor issues. Without the source code, its going to be difficult for the developers to clean up the bugs.

Somewhere in the dialer menu.

v45 has fixed the overheating issue but it throttles the cpu when it hits 38C. I notice that it is somewhat slower when there are a few apps open at once. It could be worse (slower)for gamers.

Was she using a redmi note or 1s? I don't think the 1s has this problem.

The redmi 1s bug has been known for a long time. According to Xiaomi, it cannot be fixed easily so its still a problem.
Check the thread below for a workaround using a number fixer app.

Did you measure the power consumption for v45? I looped a 720video at moderate brightness and it still gave 6hr20min so little or no difference there. Browsing might have been worse but I didn't measure.
I think the best stock rom is 37 with some tweaks for the memory issue (not zram).

If its the wcdma model (which it should be if really came from directd) then you should have no problems with the international/Malaysian rom. Your problem doesn't sound normal or common. Fastboot flash the Malaysian rom instead of the Chinese one. The Malaysian one has English/Malay settings and no Chinese apps. Then you can update it with the latest Global 45 via ota. You should typically never ever use Chinese rom because its probably tuned for Chinese networks.

Its been answered many times in the past, take some time to read the common problems and fixes in the threads.
Theres also a few FAQs on the official website which I found useful and I think answers your question.

If you're using the stock google keyboard change the input language to include Malay. You can have more than 1 language.

I think the explanation was that the problem was buried deep inside miui and is difficult to fix. Probably only a version jump like miui v6 will fix the problem.

From the time the 1S came out, the rom was always in beta mode. The recent fixes for heat and low memory was done in a lepas batuk way. Maybe they don't want to spend time on fixes on the 4.3 platform and will focus on kitkat as their first real stable and good rom.

You'll lose all your data on the sdcard if you format it. You should be able to format it using the menus on the phone itself, so formatting it that way is idiot proof.

Windows should normally auto install the mtp driver when an android smartphone is plugged in I think.

Its an accurate assessment according to the specs. The theres no other phone with dual sim, sd card slot, >=300ppi resolution, small <=5", snapdragon 400 cpu, OTG usb support, bluetooth 4.0, very good rear camera (high mp does not=good). The only other phone is the Honor 6 which is bigger.
