Two questions:

Did you set the file size in Androbench to 512MB? That's how we are comparing our results for this test.

Is this after a recent factory reset?
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] sclip:
Has anyone tried manually TRIMming their NAND (say, via this app) to see if it improves performance?

[Xiaomi Mi A2 / 6X Guides, News, & Discussion] sclip:
Can you post a screenshot using 512MB file size?

EDIT: I am on 201909 update on Stock and my Seq. writes are only at ~40 MB/s, and the Random writes are at an abysmal 8 MB/s.

Are you sure that 128gb is not affected by slow emmc bug ?

And how is the performance of this phone after all this time ?
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] RizwanH20:
Yes as per stated by people.... Even benchmarks show 128 isn't affected.

Performance for me had been awesome. I've been using it since 2 months and everything has been smooth so far

The issue with wiping cache and freezing IS a software issue

The issue with slow copy speed is NOT, it's a hardware issue, I have disabled encryption, use a custom rom and custom kernel, benchmarks in androbench did not change at all, but I didn't have the issue with clearing cache
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
Yeah, my theory is that the encription (or kernel) seems to aggravate the problems of the slow emmc.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Nebrassy:
It's a kernel issue, it's fixed in hex and custom roms
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Hemicrusher:
Just got my Global 4/64 A2, updated to Pie and I have no issues. Testing with Androbench and 512MB file size, I get 285/218 Read/Write. Not sure of the cache issue as I don't use Chrome, but I moved a 1GB file onto the phone and deleted it and it behaved normally.

Reading through all these threads makes me think the issue is multi tiered. Some people might have buggy memory, some fine. Since some that went from stock ROM to MIUI solved the issue, their issue is software. If it didn't correct it, it might be hardware. (Also some people troll and make up things to get their point across, in order to make the issue seem worse that it is. These people may be clouding the problem)

Or it's all a software issue only and installing Android is setting defaults that cause the problems. I do IT and if I do manual OS installs on same spec PC's, sometimes the OS picks up different settings for each computer. Only time an install acts the same on all same spec PC's is when I roll out a pre made OS image.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
The fact that only some of the A2 have this issue is why I think it's hardware. Maybe the new ones don't have this issue anymore.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] r_kalar_2:
I can see no problem with my mi 6x 4/64. How can this be a hardware problem?
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
Xiaomi sometimes uses different parts for the same model. As you can see for my post installing MIUI didn't solve the problem. Some custom roms only solve the cache problem (Wich has been only one of the consequences of the slow emmc for me)

So guys, we are at 24 december, there is no solution for this ? how can i apply HEX kernel? someone has a temporally solution until xiaomi realease the fix ??

thanks and merry christmas.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
Unfortunately Hex didn't fix it for me. No update from Xiaomi or Google about this issue either.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] verttl:
Same here.

Someone said that this bug is fixed in Hex kernel but that wasn't the case at least for me. I'm running global 4/64 variant and I have had this bug on all kernels(hex, noob, insignux) and custom roms(various jasmine & wayne roms) I have tried.

I used this phone for a long time before noticing that I also had this bug, because sometimes read/write speeds are just fine for me. If I run androbench with 512mb test file speeds might be anything between 50-290mb/s but if I use 1gb test file sequential write speed is guaranteed to be way less than 100mb/s.

Anyhow I haven't noticed any impact of this bug in my daily use. It is just annoying to know that my phone suffers from inconsistent write speeds.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] r_kalar_2:
This is for 1000 MB with lots of apps running in background. The bug may be affecting very small number of devices now.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Hemicrusher:
I just ran it again at 1000MB and it closely mirrors your numbers.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] carboy00:
I agree that it doesn't really affect daily use but my only issue is when trying to clear any cache in Chrome will cause the phone to reboot. Clearing cache via the Files app was alright even if it is a little slow.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] ZaldhyDarwin:
I'm also getting low speed results on random write but moving/copying files in file manager doesn't seems affected.. Maybe androbench app bug?

Random Write and Read slow... Phone freeze every time...
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] joaovictorsouza:
My other Mi A2 with custom kernel... Both is 4/64... :/
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
My results are for sequential write
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] RizwanH20:
Here is what I have to say about this.

First and foremost, my Device is 4/64 Model and I have faced this issue since I bought my Device with Sequential Writes ranging from 43-54 MB/Sec(With Androbench).

After updating to Pie, this issue was still there and got me annoyed and forced me to Hard reset my Device and out of nowhere, this issue is gone. Here are the screenshots.

I got poorer results with 64 MB file size and way better with 512 MB file size.

So if it's a hardware issue, why did it go away for me just after a factory reset ?

For everyone who is facing this issue. Hard reset your device once and tell if the problem persists.

Thank you for your time reading this
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] RizwanH20:
Here is A1 SD Bench results,

Please note that I was facing slow writes issue before Hard reset
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] verttl:
I'm pretty sure that the bug will come back though. I have clean flashed multiple roms sometimes speeds have been just fine (usually after fresh start) but eventually low write speeds come back to haunt you :(
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] RizwanH20:
No no no,

My point was that if this gets solved (even if temporarily)

by just a factory reset, how is it a hardware issue ?
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
After a factory reset, there are no apps or large processes in the background, so you couldn't see the problems with the emmc since the bug it's mainly with large files. I don't think that proves that it's not hardware issue.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] HTJB2018:
hi guys

i order 64/4 a2 from china

and after that i aware from slow emmc

don't unbox the phone asap sell it?

or what?

my question is what i do now?

i'm very obsessive

Forgive me for awful English :/
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] r_kalar_2:

[Xiaomi Mi A2 / 6X Guides, News, & Discussion] HTJB2018:
what about daily usage? in gaming or social media?

this issue affect on overall performance?

if yes how much?
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] DarkSoul101:
Background apps are stored in RAM not storage!
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
I'm not saying that I know the exact reason of this bug, it was a theory, I know that they are stored in ram, but they still have to be loaded from storage. All I know is that I tried a lot of custom ROMs and kernels and none of them solved the issue, that's why it's likely to be a hardware problem for some of the phones (Since Xiaomi uses different parts for the same model as far as I know)
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] DarkSoul101:
Custom kernals are based on the source codes of the original kernals. That's why most of the bugs in the stock kernals are present in custom kernals as well. Also, installing the miui fixes this issue.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] C4SCA:
I would say the issue is not hardware but the software part of ENCRYPTION.

As any flash memory, when its bad, its bad, there is no coming back. So failure cant be hardware

But if HaiderHady is running Androbench before and after a hard reset and the bug is gone with the 64MB and 512MB files after a reset, then this would be a software issue. Hardware cares less what software is installed....bad is bad.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] r_kalar_2:
I don't have the bug. But what I have read till now that it doesn't affect day to day use, social apps or game. Better ask them who has the bug.

Hi guys, I've been using the A2 for almost a month and I was wondering why sometimes my phone is slow or the download speed is just so awful (around 4-6mb/s and I have a 150mb connection) and I found this thread, I don't really know much about the emmc storage and all of that, but I did a benchmark with Androbenchmark and I got this result with 64mb file, my phone's still under warranty should I change it or is this bug gonna be fixed or will it break something in the future? I'm planning to sell/gift this phone in some months.

edit: my a2 is 4/64
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Hemicrusher:
Numbers look fine. But download should not impact eMMC because evern the slowest numbers that people are getting would exceed your ISP connection.

Also, download speed through your wireless LAN can very depending on things like if there are many other wireless networks around you. channel collision, distance etc. Do you have a computer that is hardwired to the LAN that tested the speed? You might not be seeing the advertised 150Mb/s at all.

I live in an apartment with 30 wireless networks that I can see. Plus all the smart devices like Google, Amazon, lights, cameras, phones, laptops, TV's etc. I have 300Mb/s internet and many times I only see 8MB/s on my phone or laptop and sometimes as low as 3MB/s, where the PC that is hardwired will always see 30MB/s
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] yukkio:
Just installed hex kernel and the problem is gone, so that is a bug in the kernel (like someone said before). We have to wait until Xiaomi includes the fixed in the next update. Random writes at 100MB.

BR.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] ockito:
Thanks for your reply, yes I do use my computer and get around 20mb/s that's around 180mb, also I forgot to mention that even my moto g osprey downloads faster than my A2 and my router can deliver up to 433mb over WiFi in 5ghz, and most of the time I'm no more than 3-4 meters from the router. Anyways, if the problem is not that serious I'll stick with my phone then, thanks!

Edit: Well I enabled my 5ghz WiFi to test if I get more speed and yep, I got almost all my bandwidth, so... I'll stick with the 5ghz from now on

From up-down, 1. Modem WiFi 2.4ghz, 2. Router WiFi 2.4ghz, 3. Router WiFi 5ghz.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Hemicrusher:
Yeah, 2.4ghz is very crowded......It can be faster than 5ghz at a distance because it penetrates walls better and carries farther, but it has to fight with 90% of the smart devices that polute the airwaves.

Glad you solved it.

Have a great New Years!

Try clearing cache of Google Chrome and then use your device. If it doesn't stutters then your device is actually not affected by this issue.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] AB_02:
I tried clearing chrome cache...

The process is slow and device stutters... I can see the numbers( cache data) getting reduced when i jump to that screen.

Is this for every application or specific to chrome?

However, i managed to delete a 4K video (1.6 GB) within a second from files app and jumped to chrome to write this reply...

Something is wrong and i don't understand this...

Sequential write speeds with latest Havoc and Hex-kernel are still affected by this bug atleast for me. After clean flash first test with 1gb test file was fine with 250mb/s speed. After some use speeds have decreased to 80-100 mb/s. That this still better than what I used to have with wayne version of carbon rom and insignux kernel, but other than that performance(gaming, multitasking) is terrible compared to carbon rom.
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] Hemicrusher:
OK, so I started seeing the slow Seq Write today with a 512MB test file in Androbench. I notice that I was getting wifi activity when I ran the test, so I turned it off, along with data and BT. Guess, what? The Seq Write speeds became normal. I then played around and was able to duplicate this over and over.

With 2.4 Ghz wifi I get the bad Seq Write speeds, with 2.4Ghz wifi off or using 5Ghz wifi.....Seq Write speeds are normal.

So I am only seeing this issue with 2.4Ghz wifi on and can someone test?

I think people don't know how to correctly verify it, or speaks on impulse or out of ignorance, because you have 3 people that say that Hex kernel fixes it, and 3 people that say that it doesn't fixes it.

So yeah...
[Xiaomi Mi A2 / 6X Guides, News, & Discussion] :
In my experience, that solves only the cleaning caché problem, that's just one consequence of the slow emmc. All the other problems are still present for me. (I tested a lot of roms and hex and still had slow writing in androbench)
