Black Screen of Death BSOD

Announcement: Maybe we are close to a software solution
Dear Friends,
my HM2014813 has several problems:
On some AOSP roms I get BSOD: When screen gets locked and black, I can't turn it on unless I remove and reinsert battery.
On LineageOS PowerOFF does not work properly. Ends in a situation like BSOD
After booting into TWRP the touchscreen is unresponsive. I have to lock and unlock, to get response.
I think I'm not alone with this problem. Most of us get recommendations like that: Replace Screen
This problem is not present in every rom. So there should be a solution without hardware modification. What else can we try?
For reference here are the HM codes: source
Redmi 2 1/8GB & 2/16GB/Prime = HM2014811 / 17/18/21 (wt88047)
Redmi 2 A / Enhanced = HM2014812 / 13/16 (wt86047)
Redmi 2 Pro = HM2014819

Before I continue, I'd like to remind you that Redmi 2A is a china-only phone, the chipset isn't Qualcomm based, but Leadcore based. My fellow friends that I know that have a WT86047 aren't Redmi 2A's. They're running Qcom and have no signal loss in my country.
I picked WT88047, but honestly I've seen them in all of those variants (except Redmi 2A variants). I have 4 friends that bought 2016's batch of shipped RM2 (Prime or just RM 2). These friends of mine didn't buy at the same place, 2 of them bought it online and the 2 others bought it from a local vendor (not an official Xiaomi store). From those 4 friends of mine, 2 of my friends got the HM2014813 (WT86047), one got HM2014818 (WT88047) and the last one got a HM2014811 which is the same as mine.
All of them (including me) faced the same bugs (BSOD, screen freezing, TWRP not working). So it's not just a specific variant of RM2, but all of them. Hypothetically (CMIIW) all RM2's that are shipped at 2016 above nearly all of them have this bug (unless you bought it from an official Xiaomi store, which is pretty much hard to find, because Xiaomi don't show, even sell, old phones). 2 of my friends sold their devices, one friend of mine sticked it with it's current case and stayed on stock MIUI & my last friend (with the HM2014813 - WT86047) followed my lead by changing his screen with an official screen that he got from a relative that has an unused RM2, bought from an official vendor. Now me and him can go custom rom or modding all we want without those old bugs that used to plague our phones.
So to the RM2's batch 2016 are all shipped with bad and faulty hardware parts. Mostly nearly of them are faulty sensors. Or maybe those RM2's that are shipped are refurbished RM2's that are given bad parts or maybe bad LCD screens. Like I said before in my previous posts about this, It's the sensors. They are totally bugged. I don't know what made them that way. Why I said it was the sensors? Because my old front sensors got changed when I checked it with a system specs app. My local part vendors sell RM2 LCD's and when you buy a LCD, it's a whole package, you can't by per-parts (unless you disassemble them one buy one). What I mean "it's a whole package" is if you buy an LCD, you will get the touchscreen and front sensors with it. If it's not the sensors, maybe it's the touchscreen (just using my logic here)
I don't know about fixes and stuff (without having to do hardware modif). I'm not a developer, I don't understand that much about BLOBs and shims. Well let's hope someone who's a developer and has a RM2 with those bugs show up with a fix so that people don't have to do any hardware modifications on their bugged RM2's.

Miui stable and best.
All custom roms have good interface but music enchancher , camera not satisfied in custom roms.

Well custom roms are for modification, so If you're not impressed with how the music sounds like in custom roms, you could always just install a mod for it. There's Viper4Android, Dolby Digital Plus, AM3D Zirene, etc. Just find what you need, flash the mod per instructions you need and voila, you've got better music in you're custom rom. Installing these sound mods even work well in MIUI. You've got dozens of Camera apps that may (or maynot) go better on in custom roms than MIUI. Just saying though, if you love MIUI it's fine to stay on MIUI.

For those who has the same problem, try enabling portable hotspot. It solve the problem for me, but yes, it'll also drain your battery faster

I tried it once when my device was still having those bugs. It doesn't work. At all.

I had two redmi 2 online and both had the BSOD issue. It didn't matter which MIUI version it was on, it can still get triggered into the BSOD.
This is the procedure that triggers it.
1.Start an app that generates a lot of objects
2.Keep the device with the app until the back is warm/hot
3.Exit from the app or click home
4.Now quickly press the side power button to turn off screen
5.Redmi Black Screen and cut off from power even if you had music app on.
I have concluded that it might be a hardware issue since I had test another none online redmi 2 with these redmi 2 with the same MIUI version. What should triggered the same effect did not affect the none online redmi 2.
Perhaps using a soft lockscreen button might be able to avoid this issue.

Mine starts getting this problem after I changed the display (bought cheap from aliexpress). Never had a single problem before, while now miui is the only rom that works

There you go, another living proof that BSoD is because of a faulty display. Did you change it again? Or are you still using the cheap screen you bought from AliExpress?

Sorry for delay. Just tried last lineage build, as said it works except on power off

For this Power off issue i've made a automate flow that boots into recovery and offs from there.
.. And we have a "living proof" that this hardware problem can be solved with software.

Then you should thank the devs for pulling this one off. Either they've tweaked or fixed what created the bug or because Android Oreo doesn't communicate with device drivers the same way as it's predecessors. Thanks for testing Oreo and latest Lineage. I'll recommend these to my other pals that are still bugged with BSoD. Cheers :highfive:

and how do we fix bsod with this app, could u elaborate more ? never use it

now i got my mi8

so now i got my mi8
well have to say im not imprest
1 no face unlock option (only if u change ur location to india)
2 now that i got face unlock to work it good damm dont work wen i have my glasses on bummer
3 there is no procent in batt
4 it seems verry laggy beside op6
5 only 1 color for led

My face unlock works without any location info. It works fine, also with my glasses on. But is not really secure imho, so i just use FP wich is almost instant.
There is a battery percentage but you have to swipe down once. Perhaps Miui 10 allows it to be next to the notch.
I have no lag at all.

Face unlock works fine here, never had to change location for it, works even with sunglasses on and of course in the dark (thanks to IR).
Battery % is available in MIUI 10 without pulling down notifications.
Lag, never seen.
LED-color should have been known if you've seen the big LED-thread.

1 You have a fingerprint sensor, what are you talking about?
3 Yes there is, pull down the status bar.
4 The phone costs 100€ less than the OP6 and offers pretty much same specs.
A SD845 phone can't be laggy, it can eventually be less snappy when compared to a phone which pretty much has EAS built in. Paying 100€ more for a software feature than can possibly be ported is silly unless you have money to throw ( at which point why'd you buy a 450€ phone and not a 600-800€ one )
5 Oh my god, a one-colour notification LED, the horror.

There is NO so called "global ROM" out there for the Mi8 yet...

Are you on some old dev rom from [Firmware] Xiaomi Mi 8 / Mi 8 SE [DIPPER/SIRIUS] [Auto updated weekly!] then, seeing you are on 9.5.1.0. Us others on Chinese roms are on 9.5.9.0. Wich could explain issues with faceunlock and such.
Xiaomi themselves have not released a global version for the Mi8/8SE yet, so it's odd that that thread offers globals.

I guess the seller opened up the box and installed stuff like Google Play for you including a early global update not available to customers. Maybe that's why there are some things not working as expected, like lag or feature issues.

How to remove Black Bar in PUBG

Title says it. In the screenshot you can see the left side where the notch is, the screen is black. I noticed the Chinese version of Pubg doesn't have this. I wonder if the global version can stretch all the way
*EDIT* with an update to MIUI (mine is Chinese), the problem was fixed
*Either that or PuBG update fixed it but I don't remember getting a pubg update

NVM, the latest update where the notch can be unsmoothened seems to have fixed it

Or you can switch to xiaomi.eu and have the benefits of bouth global and Chinese ROMs and more. LINK
You will need to unlock and install TWRP thought. No need to root and you will not void the warranty from what I read.

I know yes. I allrdy applied for unlock 3 days ago!
Thank you.

I really need some understanding. Wdym by "benefits" of Chinese version?
Does .eu have proper notifications? Because in Chinese notifications seem like a complete train wreck. Sometimes they show sometimes not. Some make noise while others don't. Particularly, I use Muslim Pro and the adhan never plays. Only vibrations.
If I remember correctly, it worked fine on global on my OnePlus 5T before.
Is Xiao AI replaced with Google?
Does the theme use Chinese or English themes? (If I know correct, the Chinese themes are better)
I saw all the extra features in Xiaomi.eu. But small things in Chinese bug the heck out of me. Like notifications not working properly or showing on lockscreen. Xiao AI, Chinese language here and there. Improper Google Integration(like Casting is broken) and many other small things which I don't recall. I'm very worried if those carry over to Xiaomi.eu
But then I don't think I have much of a choice anyway since if I heard correct, the 8GB doesn't support global ROM or something. So I might just be left with Xiaomi.eu.
But I just have 188 hours to unlock . Which i think falls on April 9th

After the update it's now more like the iPhone X with the options being moved a bit away from the curves so nothing is cut off. Also makes it easier on the fingers to reach things.
But most importantly, no black bar(s)

Specific features in X2 Pro

Hey guys,
my mi9t was dead recently and i'm in the market for a new cheap phone. I resisted realme for a long time due to color os until someone pointed it out that the new realme ui is better than miui, so i am going to give it a try and stumbled upon how cheap the x2 pro is given its spec.
Well since specs arent everything and there are many little things not covered in reviews, i would like to ask if
1. it has AOD and is it customizable
2. Does it have screen off hands off ok google, i use it a lot
3. since it is using in display fingerprint sensor i made the mistake of not backup-ing the resist partiotion in mi9t making it almost useless. Do i have to do the same thing and is it bootloader unlockable? i saw quite a lot of custom rom available and thats kinda good
4. is there any small things i need to know like build quality, lagginess
Thanks

It's a good phone overall. I am using CN version, however I recommend you get the EU version to get full gapps support.
Yes AOD on realme UI is fairly customizable. You can choose what to show and the clock. Display format and style. Beyond that not really.
EU version has the all google apps as far as I know but please double check.
Bootloader is easily unlocked. Rest i am not sure.
Built quality is superb. Battery 0 to 100 percent in 36 minutes. No lagginess with stock. Pretty fast boot due to UFS 3.0 (not all variants have this so pls. be careful when ordering/buying). People say cameras are ok and not great. For me upgrading from LG V20, they definitely are better. Also you might have to disable smart power saver for apps to work correctly i.e send notifications pop ups etc. Maybe that's only for CN version.
I hope this helps.

Question Redmi 9T 4/64 bottom edges isn't working always.

So when i'm typing on my phone i noticed that the bottom edges, left and right isn't working always. The backspace and the "SHIFT" button isn't working, only if I tap it twice. It's hard to explain i rather show you.
In this video I tried to press fast as i could the bottom edges while i hold my one finger in the middle. And if I press long enough, like 1-1.5sec then the touch will record my finger. And in the second video I turned on to track my touch location, but as you guys see the multi touch tester isn't recognize if, only after 1-1.5sec.
I'm not sure if I wrote it down correctly, but I hope you guys will understand.
Can this be fixed?

Don't worry, I have the same problem as you. This is probably the screen and hardware problem, not the software, and you need to learn to life with it. :/

DotOS is a good choice if you want a good looking ROM out of the box.
ArrowOS if you want a light ROM that is simple looking. On the other hand, Bliss ROM, DerpFest, Evo X & Corvus can be heavily customized heavily if that is your thing.
