Device extremely lag and freeze A LOT even after 3 clean flash through MI FLASH

Hi guys, since 01/01/2018 my device is lagging and freezing A LOT. It started suddenly. I was using it normally, then put it aside for like 20 minutes and when I pick it back it was extremely lag and freezing almost every second.
I was on latest Global Beta ROM from 7.12.14. Factory Reset through settings menu couldn't fix it. In fact, it only got worse. It spent a whole night just looping on the Mi logo. After hour, in the morning, I picked it and it was on that Language Setup screen. But totally freezed. I kept pressing my languague option and nothing happaned. After 6 ~ 8hs I finally managed to enter developers settings and activate USB Debbuging and OEM Unlock option.
After 3 days I managed to unlock my bootloader and tried to flash the same ROM again through Mi Flash. Device kept extremely lag and freezing. I already flash 3 different ROMs, Beta and Stable and nothing changes.
I flashed TWRP but even there the phone freezes. I couldn't even make a backup or flash a ROM. Then I flashed another ROM through Mi Flash and still nothing changes.
Right now I'm waiting for my device to unfroze and try to install TWRP once again.
I'm starting to think that maybe it's a hardware problem. I bought it through Gearbest. I'm almost giving up on trying to fix it myself and contacting Gearbest.
Anyone get any advice of what shoud I do? Or have any experience with Gearbest warranty?

I am sure there are so many other also experience this problem, including me. This really annoying. I am thinking to move back to Miui 8 to see if the problem still persist

What rom did you flash with MI Flash?
If i were you what i would do is the next. Flash the latest stable version for you MI 6 variant, relock bootloader and send it for warranty.
Those issues sound way too "extreme" for an stable rom even for a MIUI rom.

I had the same issue with my 5s. It was a hardware problem so you will probably want to exchange it.

I gave up. I've flashed a bunch of different MIUI ROMs through Mi Flash, both Chinese and Global, beta and stable and still nothing. It's a hardware issue.
I contacted Gearbest and they asked me to send the phone for them to repair. But I'm from Brazil and it would cost too much to send it to China. Also I would have to wait like 3 or more months to get it back and would have to pay import taxes again.
In my case it wouldn't be worth. So I ended up picking a 100 USD refund and will try to sell it with this defect here in my country.
I loved this device. Gonna miss it. I ordered a Moto Z2 Force locally. Hope its as good as Mi6.

What a shame. I love this phone.
Did you try flashing the stable global?
I have the ceramic version - beautiful - then I used a silicon cleaner on it and it clogged my earpiece.
The phone is still perfect except...I can't hear ANYTHING! ?
AH.

Yes. As mentioned before, I've tried dozen of ROMs. Chinese and Global, Beta and Stable. No fix.
My Z2 Force arrived two days ago. Amazing device. It's bigger but has a better grip than Mi6. It's not as slippery. Battery is also quite good, even through it's only 2700mah. Mi6 is obviously better in this scenario, but Z2F isn't bad.
Overall it's feels faster and smoother than Mi6 due to it's stockish Android. I miss some features of Miui, but damn it's good to have a proper notification bar again.
I almost don't take pictures, but the rear camera seems a bit better. The front one is definitely better and even has a dedicated flash.
Hope to have better luck with this device.

What a shame! Even got back to MIUI8 does not fix it. Wtf Xiaomi has done with this model???

I'm almost sure it's a hardware problem. Maybe a defective lot. I've seen some people reporting the same issue since mine started happening.
Flash the latest stable ROM, relock bootloader and send it to warranty. It's the best thing to do.

mi6 freezing a lot (and how I fix it)
Hey!
My mi6 has a same problem. But I just buy the a good launcher like Nova launcher and a iconpack. So since this change there is no freezing at the moment.
Maybe your problem can be fix too. There is no cost to try;
I found your post when I was searching a solution for my case. For me just a little change and the device is fast again without freezing.
a thanks from another brazilian!

Redmi Note 8 Reboots sometimes

Hi guys. I bought Redmi Note 8 a month ago and I faced a boring problem. I can use the smartphone very well everyday but the smartphone reboot itself when not using. This happens only once every two days. I see that the issue don't effect using of phone but it's quite annoying. I think I can find solution in xda-developers. Can you help me about this problem?

I bought this device for my wife and have the same problem.
Yesterday restarted one time, and today twice.
I did a factory reset but it didn't work.

Wow guys, never faced this and i'm using it for 2 weeks now.
Do you ever modified something system-side that could cause this? Thinkering with developer settings... removing some system app, anything else? It's really weird.

new update 11.0.4 released try updating

15-05-2020 no solution yet, hardware problem, try to exchange in the store you bought, I have 3 of these garbage that I bought online and I have no way to exchange

Can try this?
I know the post is old,
If you know how to uninstall system apps with ADB can test removing com.miui.msa.global (Main System Advertising: Advertising and data collect).
It's safe to remove, but need testing about the restart idle issue. I'm testing right now.
EDIT: Doesn't work. Phone restart after few days.

Redmi Note 8T app freezing

I bought my wife a Redmi Note 8T for xmas, and unfortunately it's been an absolute nightmare to operate ever since she received it. It works perfectly after a reboot, but after a few hours or perhaps half a day of use many of the apps on the phone refuse to open, they just display an all white screen or sometimes the logo of the app, but never open fully. You can close them, or press the home button to go back to something else but that app will not open unless you reboot the phone again.
I did multiple factory resets and re-set everything up but the problem always comes back. I ended up returning it to the retailer (I'm in Australia but the retailer was overseas), but they insist they couldn't re-create the problem, and refused to tell me if they were actually using the phone for a few hours before trying the apps...they seemed to be only ever trying it out after a reboot. I won't name the retailer but their customer service is extremely poor and I certainly won't be using them again. In the end I asked them to send the phone back to me, at which point they demanded $70 to return it as "there were no issues found". I paid it, got the phone back and then cancelled the charges on my credit card just to annoy them.
Anyway...I got the phone back a couple of days ago and set it up again from scratch, MIUI 11.0.5, added my wife's google account, installed half a dozen of her apps (FB Messenger, Whatsapp, Bring shopping etc)...she used the phone for about 2 hours then Messenger and Bring refused to open with the same problem. I can only imagine it's some kind of CPU or RAM issue. It's the 4gb/64gb model so it should be very capable of handling such a light load. Model M1308C3XG.
I figured I'd cut my losses so went and bought her the Mi 9 Lite from a local retailer yesterday morning and it's been working perfectly ever since. Cost twice as much as the 8T but at least I'm not copping an earful any more!
So...I have a new 8T that's has nothing to do....figured I might unlock the bootloader and try TWRP, see if it makes any difference. Did the unlock last night but it tells me I gotta wait 168 hours. Sigh. Anyone got any ideas in the meantime feel free to throw them my way.

Hi Bro.
Me also facing this problem. I am using redmi note 8 (Indian verison)4/64GB variant
I faces the the same problem u mentioned above.
Me also reseted the mobile but the problem still occurs.
Also me unlocked the bootloader and installed the original fastboot flash ROM. But still the problem occurs.
I don't know how to solve this problem.
If you got some solutions suggest me....

Note 8T

I never did get it solved mate, but you know what's interesting is that I can't recreate the issue without a SIM inserted in the phone. I transferred the SIM into the new Mi 9 Lite and it's working fine, and I have been playing with the Note 8T without a SIM...the issue hasn't come back. So my guess is this is a fault with the GSM hardware in this model of phone...it might only happen if you're using a certain frequency which is why not everyone has the problem?

Hi, I'm having exactly the same issues, even though I changed ROM. Seems like a hardware issue. Did you manage to fix it?

Question Updated to MIUI 12.5.3 and fingerprint sensor stopped working.

Hello everyone! Hope you're doing ok!
As the title says, I updated to MIUI 12.5.3 Global stable rom (from OTA) and then I started having issues with the fingerprint sensor, only working half of the time. Then, suddenly, it stopped working completely. I've read online that it has happened to many people on many devices. The only answer I can find is to flash xiaomi.eu rom on my phone. Does anybody knows if installing xiaomi.eu would help? Does anybody have had this same issue before?
My phone is 3 months old, I always use a case and screen protector, and I haven't dropped it strong. (It fell off of my hands a couple times, 2 or 3, but without any major impact, had a very safe landing haha so I doubt the fingerprint sensor broke.)
I'm trying to find any kind of solution to this problem, as I always use the fingerprint sensor
Thanks in advance!

I'm having the same problem, any fix?

Same problem, any fix???

I have bad news. I managed to install xiaomu.eu, I'm on MIUI 12.5.5 and sadly, the issue was not fixed. I thought that installing the most recent version of xiaomi.eu would solve the problem, but no...
I don't know if going back to MIUI 12.0 would solve it, as the problem appeared when I upgraded it to 12.5.3, but I won't try it for now because i'm kinda tired of re-setting my phone and apps lol.
If someone downgrades to MIUI 12.0, global or eu rom, and it solves the problem, please let us know!

it won't be solved by changing ROMs as it's an hardware issue. Go to the service centre and get it replaced

The thing is I'm not so sure its a hardware issue. The problem started when I updated to MIUI 12.5.3 and the fingerprint stopped working, and more people have the same issue after updating too.
But as changing the rom didnt work, I can assume maybe, in my case, is a hardware issue... And I doubt it tho, because I haven't dropped my phone as hard for it to broke.. unless the sensor is so weak it breaks with a little drop

I had the same issue, unlocked bootloader, flashed crdroid, and fingerprint stopped working, thought it was due to custom rom, flashed OG MIUI Firmware locked bootloader and fingerprint still wasn't working, claimed my phones warranty and the service center told me that they'd have to replace the fingerprint and the problem maybe with the motherboard as well.

So it is an hardware problem? Seriously?

Yes, it's a hardware issue. Last week I brought my mi 11 lite to the service centre and they replaced the fingerprint module and it's working again

So why the fingerprint with the previous software still active?

Happened to me 2 days ago, phone was just 3 months old.

It's hardware issue,sensor on mine Mi 11 lite 5g died two months after I bought it.Flashing older roms won't help...In my country there is no way to raplace it so I've got other phone...

Im not use fingerprint use faceid

Question Poco F3 Microphone issue in voice/video calling apps

I just bought a new Poco F3 yesterday and the phone is good in most aspects but there seems to be an issue with the microphone in voice/video calling apps where my voice is really low or inaudiable but the microphone works fine during normal phone calls where my voice is loud and clear. I have seen quiet a handful of questions regarding this on google and on here but there doesn't seem to be any solution in those threads for the issue other than to try disabling "Google's" permission for microphone which I did but it didn't help. Also, I am currently on MIUI 12.5.6 which is the highest version available to me. Any help would be appreciated.

I had this same issue in aosp roms. I never get this in MIUI. Maybe it helps to flash a Xiaomi eu rom.

Thank you for the reply But this is a brand new device that I just got yesterday and its still under the return period in amazon (where i got it from) so I would rather not flash custom roms or unlock bootloader. I was just hopeful that someone had an fix that works in stock rom. If there is no fix then I might just return the device. Again, much appreciated.

Just an update, I decided to return the phone because there doesn't seem to be any fix for the low microphone issue during voice/video calls in POCO F3 other than trying to flash custom roms, which may or may not fix the issue. I don't think most POCO F3 has this issue though so new buyers can probably buy this phone without worries. Its a great phone for the price range but it would have been nice if there was an update to fix it or a simple software fix for the issue.

It's a shame you had such problems with it. I also have a very annoying error with the proximity sensor. But that is also known. And also tends me to sell the F3 and switch to another brand. Xiaomi can not program software without error. And throw out one smartphone after another. Miui is total garbage. And it can not be that I have to flash a Rom that everything is more user-friendly.
Which smartphone will you choose now?

I didn't buy phone for me but I think I will go the safe route and go with some mid-range Samsung because at least they have their software mostly in order and hardware errors are minimal (apart from Note 7 explosions and S20 FE ghost touch issue, lol). This was the first Xiaomi/POCO phone that I bought and it was because of the amazing SOC for the price and the great custom developer support but I would probably not buy another Xiaomi/POCO after this. Anyway, I don't want to make this thread into a chat session, haha. Cheers, mate.
