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

Did you try SOD Killer from playstore? Should have less battery drain.

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:

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

Oh great. Let's hope they will release it soon for eaa global.

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.

Intermittently Unable to Receive Calls

HI I am on MIUI Global 12.0.3 (QFKMIXM) Stable ROM 10 QKQ1.190825.002 and this week, my phone suddenly is not able to receive calls which happens intermittently, sometimes I can receive calls, sometimes not, but so many people called me this week (food deliveries, package deliveries, surgery call for my Wife) and they all said that yes they did call me and that I did not even receive an SMS or Missed Call notification.
I don't know if this symptom is related to finally making a XIAOMI account and logging into it via the phone's main settings.
Also I noticed since then, while rebooting the phone I get this notification that XIAOMI services could not be activated on both SIMs 1 and 2
This to me is a sad spectacle, I had this phone for about one year now and I admit to having it dropped a few times.
What could be the issue here guys? Would like to know if this is SIM carrier related or purely a manifestation of a hardware failure?
Damn, I don't want to buy a new phone.
PS I opted out of the Beta versions of Google Phone App and Messages

Anyone who have experienced this? please help and chime in??

Sorry bout the late reply, I got pixel experience rn but tbh use whatever, and I would say its worth it just be careful if it's ur first time, don't break your phone. Pixel ROMs feel hella snappy and smooth.

Cheers mate, happy to help... On Global, mate.. stock nubia, NX629J_V1S_ENCommon_V2.14
Only use stock (and super old) Nubia rom for the sake of RedMagicTime for PUBG clips. And since PUBGM update 1.2 (now PUBGM on 1.3 version) RedMagicTime stop working properly.. well, RedMagicTime still working if we change phone and PUBGM language to traditional Chinese, it's annoying, but clearly better than nothing...
I know right from the get-go this phone is too good to be true.. cheap as hell, with the top tier hardware on papers (at that time) with interesting features (RedMagicTime).
I know there's a price we'll have to pay, just don't know that price is no updates (almost) at all for this phone... Just like my nickname, nubia development team is sucks, they abandoned the customers, move on to next projects and don't care at all for after sales.. sorry for long non sense rants
