Phone acting weird on charge

Hello, my redmi note 4x is acting all weird, when I plug it in it starts this repetitive notification sound and the power charge phases in and out, probably something simple I haven't had it long, but I've never seen a phone do this, any tips for a rookie? :D
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Maybe the cable you are using has a damaged connector. (Or possibly worse is that the port is damaged on phone)

Installing MIUI's OTA updates through TWRP

I wanted to know that is it possible to install MIUI updates (OTA updates) through TWRP? I mean if I install the OTA update and then maybe flash lazyflasher after updating?? :confused:BTW I'm currently using latest TWRP build.
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Possible but only using redwolf recovery, redwolf recovery supports miui ota. And there is a guide on the redwolf recovery page in snapdragon section

Hi guys, I want to test some custom Roms, and my question is, do I need to update bootloader for oreo roms? I'm currently on Global Beta rom
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
you mean unlock the bootloader? yess unlocking bootloader is necessary for installing twrp and installing any rom
[Xiaomi Redmi Note 4 Questions & Answers] Zurk7:
Can anyone plz tell me what is the best rom and kernel to play mobile legends? Im in xiaomi.eu.

My device is mido, 4x.

Thanks btw
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
There is no specific rom which can help you with performance in gaming, But surely the custom aosp rom will provide much more performance than miui. Try out Liquid Remix oreo rom. But for the kernel i will suggest going for the Stormguard kernel, which actually overclocks the device to 2.2 ghz. which provides slightly better performance

I'm looking for USB drivers for my Redmi Note 4 (SD). Where can I get them from a trusted source?
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
the drivers should automatically install when the device is connected, however if you still want to have them

I think your pc , said "I can't trust the vendor of the driver provider"

If so, try disabling signature verification in windows,then you can install drivers from untrusted vendor.

Hi guys! What's up!

Soooo, I just bought a redmi note 4 with MIUI version 8.5 (stable) NCFMIED.

When I always buy a phone I basically root it then flash it with a pretty much empty rom

without all 23432 pre-installed apps...

Well, last time i've done it was 6/7 years ago with a galaxy S1 and then a S2...

Apparently technology advanced a lot during these years and I pretty much lost nowadays :D

I checked a bit the forum and there are tons of different versions/etc...

If anyone could help a bit or point out a good tutorial as how things are done with this phone

I'll be veeeery happy (i have no idea also about mediatek/snapdragon difference blabla...) :/

Thank y'all :)

[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Hey there Juan!

A big welcome to our Redmi Note 4 community!

Ok so basically the first and foremost you need to unlock your bootloader

Here's a detailed thread to it.

https://xdaforums.com/redmi-note-4/how-to/bootloader-unlock-variants-to-read-t3565459

Please note that this guide only works for the Snapdragon variant.

The difference you may ask, there are two variant of Redmi note 4 available, one has a deca core mediatek chip and another has an octa core Snapdragon chip. Now the mediatek chip is actually far more Superior in performance than the Snapdragon one, but every thing has a price. The actual chip was a flagship one from 2015. This means there is no support for Android versions above than Marshmallow. That's the reason Nougat is non functional on the device. However the Snapdragon chip (Snapdragon 625 in particular) is a more recent one. Because of which the development community of Snapdragon variant is far more Superior than mediatek one. The mediatek one is called "Redmi note 4" (codename nikel), and the Snapdragon one is called "Redmi note 4x" (codename mido).

Check your device chipset by using any device detail app.

Now to install twrp

This video is again for Snapdragon one.

hi everyone, i have xiaomi redmi note 4 SD. Android version is 7.0 NRD90M and MIUI version is 9.2.1.0 (NCFMIEK).

My problem started few days ago. I have a problem with fully unlocking my phone with my finger.

This happenes sometimes, and sometimes it works right.

So the problem is that when i try to unlock my phone it just lights up the screen, show me the lock screen and i have to enter the code.

And unless i enter the code, there is no way to unlock it with finger even if i press the power button few more time and try. It does the same, just lights up. After that everything works ok.

I thought that this happened after charging, but then it happened on random occasions. Just like few minutes ago, when i started writing this.

Does anyone else has this problem and do u know how to fix this?

I have this phone for 4 months now and everything was fine till this thing happen.

EDIT: got answer by Xiaomi dev, told me to delete old fingers and install them again, i hope that will be enough to fix this :)

but i still want to know if something similar happened to someone ;):confused:

Yeah, bunch of users faced the same issue. The solution was to delete the entry and readding it

I have redwolf recovery version 26 and using it with miui stable 9.2.1.0 .will the factory reset affect recovery and root?
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Please make sure you factory reset ONLY from recovery. Resetting from settings app could lead to a hard brick!

It won't effect recovery, but you may need to install magisk manager app or super su app afterwards.
[Xiaomi Redmi Note 4 Questions & Answers] IThinkALot:
Noob question but I wonder why only those phone who have snapdragon chipset gets alot of developers attention when it comes to rom development, why not mediatek as well?
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
That's because mediatek hardly updates their blobs and they don't seem to care to give vendor blobs when a new os comes out. Snapdragon on the other always update their sources on their caf page when a new os comes out. Also the mediatek processors used used in high end devices (ex mtk 6797 in mediatek redmi note 4) is already too old. That combined with lack of support from mediatek, results in poor development. The reverse applies for Snapdragon processors. That's the reason we just got full treble compatibility on the Snapdragon redmi note 4 for oreo, while the mediatek devlopers gave up on bug fixing for nougat.
[Xiaomi Redmi Note 4 Questions & Answers] met4ller:
Finally I found my thread! :D

I hope to receive an answer from someone has deep knowledges, because my questions are specific. Help me also if you just have the answer to only one question, it's precious anyway:

1-What's the truth? Amplify +naptime are useless with oreo and its doze or they can still help a bit (more than their consumption)?

2- I m using cosmic rom. Does rom (and their kernel) are specific for battery or performance consumption, or these parameters becomes neutral with kernel tweaks? for example, some roms can work worst with games than others, indipendently by kernel and cpu tweaks?

3- gaming experiences : is sufficient to create two profiles with kernel adiutor (setting different cpu max and governor) or is better to use also spectrum? Somebody told me that auditor cannot unlock gpu, so I should need spectrum. Is it true?

4- can you suggest me (a quick screenshot is enough) best settings profiles for Kernel adiutor as phone mode and gaming mode? I can just modify cpu min max and governor, I m sure there's something else to set to improve them.

5- I bought an external SD, I can't find any clear solution about how to directly move everything (or what I would chose) on it. I m looking for an app or magisk /xposed module. Like the old link 2sd. I thought that would be some news about it (like a Google or dev setting inside roms), but doesn't seems. I just found "folder" mount app that should create shortcut to SD.

6- which is exactly the setting for synchronizing rom custom settings? I found this option very useful, but after some customization, then a rom flash, i found the old settings. I synchronized Google without any results (just for Google apps, not for custom settings ).
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
1- i don't really find myself using amplify and naptime after I switched to oreo based roms. Always got around 6.5 to 7 hours of sot, but without it on oreo i am able to get min or 6 hours of sot mostly.

2-Tbh there's no rom shipped with a kernel ONLY for performance or only for battery. The deve just tweak them accordingly to get a middle ground.

3,4- check the screenshots, first is for performance, second for normal. I use stormguard kernel tho. Creating profile could be beneficial if you play some high demanding games.

5- you can format the sd card as internal storage, to use it as internal.

6-unfortunately, there isn't a method for syncing settings between two custom roms. Since each have different features and settings, so yea not possible.

---------- Post added at 08:36 AM ---------- Previous post was at 08:31 AM ----------

I rewrote the answer. Lol
[Xiaomi Redmi Note 4 Questions & Answers] met4ller:
Thanks!

1- you said that you don't use them, but then you said that without them you get less sot. So it seems you suggest using it. Confusing... :S

3- so spectrum is needed or not? Adiutor can unlock gpu or is better to let it work with spectrum?

4-why you can arrive up to 2200 mhz and I can't? My cpu max is 2016....

5- what that means? If I format it as internal, where files will finish, on external? So I will have same folders in both SD? when I plugged it maybe I did what you said, i formatted it and it ask me if u would use it as generic SD or phone SD and I put second choice, is that option you are referring to? If yes, can I move every folder in main SD to the external SD(like cut paste with pc) ?

6-yes, there is. As I told you, moving from cardinal to cosmic rom, setting was restored. So there have to be an option to do it. Also other people confirm me that. Where is that option ?
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Ok wait, i am sorry, let me be more clear :3

1- regarding the amplify + naptime i meant that you can actually skip them on oreo based roms, because the margin is actually lot lot less now. By 6 hrs i meant that's minimum sot i get, when i don't use my phone much, and usually at these moments i get about 2 days of battery. And regarding sot of 7 and 6.5 hrs, i am able to pull it off easily now by using franco kernel. I used franco kernel with aoscp and it literally gave me 10 hrs of sot and 3 days of battery life. But then performance is a bit limited. So, if you want battery life, use franco kernel.

3- tbh i don't really like spectrum. *Cough* *Cough* most of the times it isn't supported by custom kernels, and mehh i don't know what it really does with the settings.

4- i am currently using resurrection remix oreo with stormguard kernel. Stormguard kernel is actually overclocked to 2.2 ghz, that's why i can arrive upto 2200mhz. And regarding battery life on this one, it's ok-ish. Not legendary, but 1.5 days to 2 days is an average with this one.

5- yes after that you can, easily transfer files. And after formatting it will ask you to whether you want to transfer files or not.

6- no idea :'S
[Xiaomi Redmi Note 4 Questions & Answers] met4ller:
Thanks, we are almost there.

1 yes i want battery life so I could put Franco. But I still would play heavy games like rules of survival. Does Franco could affect it, also creating a performance profile with adiutor? Because I tried revolt kernel on cosmic, but I have to return to stock kernel because games had some crashes, freeze and lag despite of the performance profile. So I m wondering if I can still put all power for game also with Franco that is made for battery life, or is better to balance as i am now with stock kernel.

5- I don't remember if i transferred files to external SD, i don't think so . How to understand that?

From settings i just have 1.77gb of files in external SD (and I don't know what is it).

I just installed es file manager ("file" app manager doesn't show everything), and I can't see both SD cards, just one, the internal SD almost full. How to see external SD?

Internal SD path : storage /emulated/ 0.

External SD path? Setting it as main memory, it will become a single memory? It's very confusing....

But from rom settings I can see both. I don't understand if with the setting you mentioned I can make a single internal SD of 64gb (32+32) so everything will be simple. I don't want to make mess, I would move almost everything to external SD, how to? And why it doesn't happened, if when I inserted SD I put "keep it only as phone SD"? Sorry for multiple questions but I would just the easiest way to move everything, clear space on internal SD, apply "save downloads, pictures and obb to external SD" and understand how to see SD card on es. Maybe it's easier than what I wrote, so please let me understand.

*New question: I want to decript phone to remove double pin code at phone boot. But I also want to put same rom, app and settings without losing time to set all again. Someone told me I can just move WOLF folder to my external SD, format data then put the folder back to main SD and then the nandroid restore and I ll have everything as now, nothing to set. But also if wolf rom gain decription data, restoring backup will remove this data, so should be useless and phone will return encripted, right? Seems complicated.. If there is a solution, please write me in steps.
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
1-I don't really think if franco kernel is purely made for performance and power. As i said you can try out Stormguard kernel, even though it is overclocked, you can still manage to pull of 2 days easily. what's your goal regarding battery life? how much sot and days do you want?

5- since you formatted the card as internal, the android system makes it look as if its a part of the internal storage.

And yes es file manager will never show the external card, unless you re format it as portable storage. What formatting as internal storage means that in reality the sd card will work as an extension to internal storage. Lets keep it simple. If you want to make a total storage of 64 gb (32 of internal + 32 of sd card), then you have to format the card as internal. But since you had already done that, then all you need to do is migrate data onto it, which will move app data, images, downloads onto the sd card. And no it isn't possible to see the contents of sd card using es, or any other file manager, since the path to sd card is changed by android, and only the in built file manager can notice it.

* i don't really think that restoring an encrypted backup will be helpful :confused: As encryption says, It encrypts EVERYTHING. That includes EVERYTHING. so i dont have an answer to it. Maybe someone else can better point it out.
[Xiaomi Redmi Note 4 Questions & Answers] met4ller:
1 well, having trouble with revolt (suggested by several people), i prefer to keep the stock, as it is always smooth. But yes, I could also overclock with stormguard, and maybe I could have more fluidity while gaming thank stock.

I m looking for best SOT with both profiles. While phone use, everything at minimum consumption (but of course not app lagging), while gaming, maximum consumption (because our phone is great but not as expensive phones... For example maximum game quality with rules of survival is impossible, maybe with overclock, but still i have doubts). So, as described, the screen you posted are still good, or should I modify something?

5-intetesting! So, because I formatted external SD 3weeks after putting files on internal SD, as you said, should I just cut - paste all folders on external SD through windows? Wait, no.. Because you also said that now it's all mixed, because is formatted as single SD card of 64gb, how can I move files from internal to external? Because with built file manager I don't know how to understand what there is in internal or external - seems like es. For exemple, all pics have to be moved from Dcim to which SD folder, that path is the same?

Then, from now on, phone will automatically save everything automatically on external SD or not? If not, how to set that, instead of moving everytime files ?

*ok, my thought was right. I don't care, easier to put pin twice than move, flash and restore risking problems that I can't really manage ;)

Hey guys! I'm planning to replace my Nexus 5 with 64Gb variant Note 4.

Anything what I have to know before?

What's the versions?

How about battery life on custom ROMS?

Body creak? Where?

/system partition size?

Fingerprint soiling on screen?

How long takes installing custom ROM for the first time? (Any problems with that? Like Samsung Knox..)

Anything helps! Thanks David!
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Redmi note 5 is already launched with a pro version. While there is no change other than the screen between Redmi note 5, and Redmi note 4, the pro version definitely has a better processor and camera (Still it looks like an iphone x knock off tho).

Other than that, the battery life is AMAZING!! Like you can easily average out 2 days of battery life with atleast 6 hrs of sot.

Regarding body creak, there is nothing sort of a creak, and the phone definitely doesn't feels cheap. (One thing to be noted on Redmi Note 4 is that, the screen isn't too strong, so a screen protector is definitely recommended, but redmi note 5 appears to have gorilla glass protection)

Regarding system partition size, i guess its around 1.5 to 2 gb (can't really remember tho)

And unfortunately fingerprint gestures are not supported on miui, (not even on custom roms also)

Regarding installing a custom rom, the only thing which takes the most time is getting the unlocking permissions from xiaomi.

Basically you have to send an application/email to xiaomi telling them why you want to unlock the bootloader, it takes around 5-7 days to get the approvals, and they will provide a software with which you can unlock bootloader. After unlocking its all straight forward since you only have to install twrp, and install custom roms.

Anddd that's it! At the end, if you are thinking to purchase the Redmi note 4, then instead go for the Redmi Note 5, because thats having a better screen, and you can expect the same amount of development like Redmi note 4, once xiaomi releases the kernel sources. But if you can spend a bit more, then Redmi note 5 pro, is worth checking out. :laugh::highfive::)
[Xiaomi Redmi Note 4 Questions & Answers] anvilgod:
I bought the phone yesterday. Charged it today from 18% to 100% and as of now, time since charge is 9 hours and SOT is 1 hour and 10 minutes. The battery is now at 87%. I was connected to Wifi whole time and SOT was during using messenger and a bit of surfing on Chrome. Im on MIUI 8.5.4.0. Is this normal for the battery to already be at 87% ?? Should I do a factory reset to try improve the battery consumption?

[MENTION=6306202]my name is[/MENTION] rage can you answer to the quoted message(1), and also to this?

2-Today a guy told me that is easier to make external sd not part of internal. So I did and then migrated everything in it. But now phone seems pretty laggy. So what should I do? I need to understand that because phone now is almost useless and tomorrow I would clean everything and make it work properly.

3-I have to do that also because without format data safety net is broken( red cross on magisk) and somebody told me that I can risk if I pay online through phone. Is it true?
[Xiaomi Redmi Note 4 Questions & Answers] MyNameIsRage:
Lmao, update your miui tho, nougat is out. Maybe that will fix the battery display.

---------- Post added at 06:14 AM ---------- Previous post was at 06:06 AM ----------

Regarding the kernel and battery consumption. I guess stock Kernel should be good enough for the best of both sides.

The phone is laggy because it it actually has to load resources from the SD card, which is much slower than internal storage.

It is not really always "dangerous" without magisk , if you are sure that your device is malware free, and the payment pass through is secure, then magisk doesn't affects anything. However there are some banking apps that require magisk on a rooted phone to work.

I will requote you again , cuz I am thinking of something, will surely come up with something.
