I've just discovered something strange about my emmc, so I have this slow emmc bug (micron vendor), I have a very slow writing speed, the reading is normal. So when I clean the Chrome's or Instagram's cache (300-450 MB) my phone just dies, it restarts almost always. But when I clean my games' cache (Clash of Clans - 400MB cache, Pubg mobile - 500MB cache) the phone cleans it immediately, no freezing, no restarting. The games are in a different 'folder' in settings -> Storage, they are in 'games', not in 'Other apps'.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Professor_7:
This is due to the number of files. The more files there is, the longer it will take.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] nemesis53:
Today i've made a 2gb dummy file and copied it to the internal memories of my two mi a2s.

Result;

Gold 4/64 Micron 60 secs

Black 4/64 Samsung 1 min 20 secs

Gold one was slower (58 mbps) on adrobencch test. Isn't that weird? There is no problem in daily usage.:eek:
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] carboy00:
But when it comes to say clearing any sort of cache on Chrome, did the Micron device freeze and rebooted like many of us with Micron models typically face? And did it occur with the Samsung one as well? That's the key issue here, it does seem like eMMC vendor is what makes the difference. :confused:

Dont buy. You can't identify the vendor of EMMC until you unbox it.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] rafaelecamila:
Unfortunately Xiaomi is ignoring smartphones with Android One, and have focused on the quality of MIUI, so today, I would recommend buying a Xiaomi, but a model with MIUI, there are several other models similar to Mi A2, with MIUI.

[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
Flashing Android One via fastboot doesn't affect this bug in any way. At this point I recommend switching to a custom ROM. The bug itself is still present, but at least the cache bug is solved and you get considerably less lag.

Ok, so I have an update on this. Recently i took my phone to mi service center and showed them the issue. First they clean flashed the phone to check if its not software.

They took the bug report and sent it to their technical team to see if they approve a motherboard change or phone replacement. When i called the service center again they told me that the tech team has analysed the bug report and are working on a software fix. The service center said, they will let me know more info this thursday.

As you can see speed drops on big files. That's the problem.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] directnomad:
I agree, this test took some time to complete. But that is also given since it was 512MB testing. So my phone also has the slow emmc bug? Maybe I should return and find another phone for purchase.

What is the average/normal speed expected for a phone that does not have these problems?

[Xiaomi Mi A2 / 6X Guides, News, & Discussion] minnuss:
Everyone here is using the phone daily, it is not that big problem, because you don't need to clear Chrome cache, I personally don't clear it at all, why would I ?

I have 64Gb and that is a lot of free space...

In daily use, the phone is working fast and smooth and that is what is important. :good:

But, if you are into benchmark, return the phone.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] directnomad:
That is good to hear! The benchmarks don't really matter to me if it only affects Chrome cache, as I don't recall the last time I cleared the cache on my current phone. Just been reading a lot and this issue has come up quite often, so I thought it was more to that (people mention installing/uninstalling apps on the phone causes slow/freezes on the phone as well?).
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] minnuss:
It freezes for a 1 sec or less, depends of the app that is installing, it is normal behaviour for many phones in this price range, look, this is a good phone, don't bother with this too much.

I just finished installing new April OTA update, and gplay updated ~10 apps in less then 2min.

I would try to simplify to you and everyone else:

- Is there a problem with cleaning Chrome cache? Yes there is

- Is this a major problem, that ruins the daily use of the phone ? NO it is not

- Would I like a problem to be solved? Yes, absolutely

- Would I change the phone because of this problem? NO !
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] RizwanH20:
IDK what's happening but I wiped about 300MB of Instagram Cache and it happened in about 1-2 seconds with no freezing whatsoever.

mi a2 128gb /6gb

Hi.

I have a xiaomi mia2 128gb 6gb.

It has errors when I transfer heavy files from the cell phone to the laptop. It takes approximately 20 minutes to transfer 20 files that do not weigh more than 100mb in total. This problem happens when I transfer for example photos (approximately 700 photos) with a weight of 3gb total, it becomes unstable and begins to transfer slowly.

Also multitasking becomes unstable and gets stuck in applications like instagram and whatsapp.

I have a big back up whatsapp messages, therefore the application always worked locked, I tried another cell phone with the same back up and it does not show slowness.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] takamper:
I just fixed the slow memory bug by converting my MI A2 to MI 6X and installing havoc OS (wayne) april 24 rom. MI A2 4/64

TBH I would have stayed on Havoc OS even if it didn't fix the slow memory bug. animations are SO smooth, similar to IOS smoothness, and all the customization options you could ask for and more. no bugs found so far. best rom for MI A2 by far.

stock miui 10 pie was so buggy, it freezes if I enable MTP when connected to pc, and magisk was also super buggy. root apps didn't work and often failed to grant root permissions, it was a mess... did I flash MIUI wrong or what? lol

screenshots below are only from MIUI 10 (first pic) and Havoc OS (second pic). didn't upload stock rom because I forgot to take a screenshot before reflashing, but results were the same as MIUI 10 screenshot. MIUI with Hex kernel couldn't fix it, only Havoc OS could.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
I'm currently using MIUI eu as well, how different is havoc for 6x compared to the A2 version? I tried it before converting to 6x and I found MIUI to be way more smooth that any custom rom that I've tried. I haven't run the benchmarks yet
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] takamper:
I'm gonna be honest. I've tried every single method, followed every single tutorial I could find, but wasn't able to flash any custom rom, even TWRP sideload wouldn't work on my phone. I HATE dual partition. that's why I converted it to 6x to flash custom roms. I've never used the mi a2 (jasmine sprout) version of Havoc, can't help you with that. maybe havoc rom got better after you tried it?

IDK how to explain it but Havoc feels like it's running in 60 FPS compared to 45~50 or something on MIUI. it feels just a liiittle bit more smooth, but that little bit extra feels so good.

disclaimer: I've experienced a few bugs with my MIUI rom (customized mi-globe rom, not MIUI.eu). your ROM might be smoother than the one I used.

Regarding the cache issue, the service center gave me another update. They conveyed that, their technical team has said that there is 'No issue' with hardware or the software and that my phone is fine.

However they are ready to replace my motherboard. The service center guy definitely agrees that there is an issue but the technical team at Mi do not.

Since they are ready to replace the motherboard, I am thinking of giving it a go ahead and see what happens.
