Does the screen type we have get screen burns?
[Xiaomi Mi 4C] rob rich:
:D i think your battery is empty before that happens :D

Found this on ars technica site:

Actually it's physically impossible for an LCD to get screen burn - that refers to the phosphorous coating on old CRTs where the electron beam actually burnt away the coating... (which is technically reversible, however I doubt it would be economically feasible and requires specialist equipment)

LCDs suffer from a something similar - which is called image persistence, a static image causes a parasitic capacitance to build up which prevents the liquid crystal molecules from returning to their normal relaxed state. The good news is that it's reversible and can be performed by an end user.

It can usually be recovered by displaying a full white screen and depending on the severity of the persistent image it can be recovered in as little as an hour...

Also due to the nature of IPS panels they tend to suffer the image persistence problems sooner than other LCD panels. Modern laptops shouldn't suffer from image ghosting (not at a hardware level anyway) - on older panels is was caused by slow refresh rates and panel response times (The old cursor submarining on Apple PowerBook 140s spring to mind). Extremes in temperatures can cause ghosting or panel lethargy in older panels - most modern panels have impressive temperature ranges...

I guess I can install the nav bar mod without worrying about screen burns then
[Xiaomi Mi 4C] rob rich:
Yes :)
[Xiaomi Mi 4C] ermacwins:
I did install soft buttons last week but it wasn't transparent where aosp based roms are and was worried about screen burns so removed it
[Xiaomi Mi 4C] rob rich:
But on other phones they are often also not transparent
[Xiaomi Mi 4C] ermacwins:
Example being the desktop, its transparent and some apps also have it transparent
[Xiaomi Mi 4C] rob rich:
Yes, but before Android KitKat almost all nav bars were black :)

Is there any app that can assign long press actions to Tue capacitive keys? I need long press menu/recents button launch last app. Sadly miui doesn't have this. I know cm rom has it but need it on miui rom.
[Xiaomi Mi 4C] AgiZ10:
To answer original question, yes, dual sim works well. You assign which sim to use for outgoing calls or to ask you every time which sim to use. same with sms. For data you assign one sim.

The one sim that is primary can use 3g, lte, while the secondary uses 2g (from what i have observed).
[Xiaomi Mi 4C] rooveg:
Hello, are there any Mi4c users using CDMA/Evdo Rev. A networks? I'm using CDMA networks but the data connection not working at all neither through CDMA or Evdo Rev. A or even LTE, but the sms & voice working normal. Has anyone facing the same problem? Maybe has solution to it?

Thanks.
[Xiaomi Mi 4C] Flaxe:
Anyone else have issues with the alarm not ringing in the morning, after the phone haven't been used for 6-8 hours during the night? I'm currently using Sleep as Android as my alarm app and I've set the alarm to ring every morning, but it never does. I assume this is because of MiUI's memory optimization, which causes it to shutdown the app during the night and therefore the alarm won't ring when I've set it to.

I've tried looking for an option to customize/turn off the memory optimization for certain apps, but I can't seem to find any option for this. Anyone experienced the same issues and have any solution to it, because the alarm is kinda necessary for me ^^
[Xiaomi Mi 4C] ermacwins:
Well the default alarm works fine for me and I'm on build 5.11.5
[Xiaomi Mi 4C] rob rich:
Default alarm app works fine for me too
[Xiaomi Mi 4C] Flaxe:
Hm, alright.. maybe I should try to use the default alarm and see if it works. You don't have any ideas of why Sleep as Android isn't working? I have tried to set the alarm during the day when I'm constantly using the phone and then the alarm is working perfectly, so it seems like the phone is doing something during the night that turns off the app.

Thanks for your answers.
[Xiaomi Mi 4C] ermacwins:
Is there any way of preventing the miui CD mounting when connecting to PC with USB?
[Xiaomi Mi 4C] wingsfortheirsmiles:
Unfortunately you'll have to do this once for each device but I've found that right clicking on the MIUI drive then pressing "Eject" removes it. It does not reappear even after rebooting the PC and also disconnecting then reconnecting the phone. Try that!
[Xiaomi Mi 4C] iamdanxi:
Do you guys also noticed a difference while pressing the back button after updating the international stable miui7 version?
[Xiaomi Mi 4C] Andiii:
yes - just rename or delete (maybe backup first) these two files with any root explorer:

/system/etc/cdrom_install.iso

/system/etc/fake_cdrom_install.iso
[Xiaomi Mi 4C] ermacwins:
Thanks, how did you find it?
[Xiaomi Mi 4C] rob rich:
Can somebody translate please?
[Xiaomi Mi 4C] ermacwins:
I take it you're on the newest build? I don't see those extra bits on 5.11.5 rom
[Xiaomi Mi 4C] rob rich:
Yes, its in newest.

I doodlet the signs in Google translate and the first of those 3 settings means Off - Miui does not limit the function of background apps.

Thats all i need to know :)

I have 2 problems with my Mi4c. I'm using the stock rom that came with my phone (it's all in English, and has Google Play)

1. I installed Google Inbox, but I can't click on any links in emails. The phone kind of freezes and I can't do anything after pressing a link. If I spam back a few times it seems to come right, but it sucks not being able to click links.

2. Message/phone vibrate is very weak. Is there any way to increase? If it's in my pocket and I'm walking around, I can't tell I have received a message as I don't notice.

Anyone know how to fix these?

Otherwise.... very cool phone

---------- Post added at 09:20 AM ---------- Previous post was at 09:11 AM ----------

In fact... I can't seem to click on links in any apps, not just Google Inbox.

Can't open link in WhatsApp either

Oh! Fixed it. Set my Default Browser to Google Chrome and now links work. Looks like the default browser was crashing/hanging. Yay :)

Now only complaint is the weak vibrate

[MENTION=1983726]ermacwins[/MENTION] I've sent you a PM about Viral app. Can you answer me please?
[Xiaomi Mi 4C] ermacwins:
Not sure what's going on as the main developer is working on other projects and we hardly communicate.

Try OGTube
[Xiaomi Mi 4C] Andiii:
It's a cable with USB type c connector and USB 2.0 high speed data rate.

So charging is better because we can use 9V Quick charge with the type c connector.

(type c does not mean anything - it can be 2.0 speed or 3.1 gen1 with 5GBit/s or 3.1 gen2 with 10GBit/s - with power delivery up to 100W or even without).

[Xiaomi Mi 4C] 7gismo:
Hello everyone,

finally got my mi4c delivered today. Simple and compact looking hardware piece, indeed. Unfortunately I'm having difficult times to flash the Global ROM, neither stable nor weekly would flash for me, it simply fails on the following error:

Install.update.zip failed!

update.zip signature verification failed

The phone came preloaded with latest Chinese stable version of Lollipop labeled 7.0.16.0. In order to get the root access I can flash the Chinese developer's ROM just fine.

I've used the built-in Updater in Tools folder to try the flashing process, it works fine with both Chinese ROMs, but fails with both Global ROMs. Using Flashify doesn't make a difference either, it goes straight to miui recovery asking for flashing update.zip, which even if the original Global ROMs are renamed to, then it won't flash still.

So my question is: has anyone successfully flashed the Global ROM (stable or developer's version) coming from the Chinese version?

Thanks for any tips and tricks in advance!
[Xiaomi Mi 4C] rob rich:
Why dont you download the fastboot rom of the global version and flash it through a PC? Or use flashify to install twrp and then flash the Xiaomi.EU Rom?
[Xiaomi Mi 4C] 7gismo:
Got figured it out by following the following tutorial: http://www.gammerson.com/2015/10/install-twrp-recovery-mi4c-root-it.html ;)
[Xiaomi Mi 4C] JaboRL:
I need to be sure about this because it is pretty much the decisive factor on whether I get this phone or not.

If (when) I crack the screen, does it stop working? (does it stop detecting my finger?)
[Xiaomi Mi 4C] chickentuna:
Well since Mi4c uses concore glass, I'm guessing that if the screen is cracked, touch screen will stop working entirely as the screen and lcd is fused together. I'm not an expert though so I could be wrong
[Xiaomi Mi 4C] f_ries:
Hi at all,

my girlfriend has a Honor 6 and it has a very nice feature which I have seen last on my old Sony Ericsson "dumbphone":

You can shut the phone down and the alarm will ring though!

Now I'm asking if the Mi4c does have this feature, too? Can anyone tell?

btw I never figured out why nearly no manufacturer put this feature in their smartphones...

Thank you
[Xiaomi Mi 4C] rob rich:
Mi4c has it :)
[Xiaomi Mi 4C] f_ries:
Really?? Wow, thank you for your answer! :D

I guess you're on a Miui Rom? Would be interesting if it also works on CM.

Now I'm even a bit more excited to receive it :o
[Xiaomi Mi 4C] gtfour88:
I updated my Mi4c with Chinese stable Rom 7.0.7.0 straight after I bought it. Then rooted it by flashing TWRP and SuperSu. Can I dirty flash a later stable Rom, eg. 7.0.16.0? Will I need to flash SuperSu after that to re-gain root or would SuperSu be carried over from the dirty flash? Sorry for the nob question.

[Xiaomi Mi 4C] strapabiro:
for the mi4c is there a non touch version of twrp without the file manager? would cause less headache navigating and would be much more secure against the average thief ...

i mean like 99% of the phone thieves are not hackers, they just wipe the phone and sell it, but when you see a file explorer sub menu, that will make them curious. even the most stupid person has access to your internal storage without even booting into any rom ... thats dangerous, it's somewhat ok if my phone got stolen after a while but my data should be "safe" when they decide to wipe it from recovery because they cant figure out the lock pattern and or password.

i'm thinking of a "flash", "wipe", "reboot" ("bye") version for the average user. is it possible? twrp is mandatory for the mi 4c since every other rom but the xiaomi.eu version is bloat.

Got my Mi4C Prime last week and have successfully put sMIUI on it to get rid of the Chinese ROM cruft. It's a real nice phone a big jump from my previous workhorse the Nexus 4.

One odd thing is when I plug in headphones I get a series of audio pops as though it's testing capabilities of the headphones or looking for buttons, if headphone or speakers are turned up these pops can be quite loud. The Nexus 4 never done this...

Any ideas?

Yea it was doing it with the ROM the phone came with and sMIUI as well, I've been trying different things, it actually seems to only do this when I plug the audio lead into the phone when at work on the laptop. It doesn't do it when I plug in headphones or in the car...

how many free RAM has your device?

I have got the 3GB version, and normally, without any running programe, I have 1.6 - 1.8 GB free, I dont know why, sometimes told me 1.6, others 1.7 or 1.8, or 1.5

why this 200Mb of diference?
[Xiaomi Mi 4C] kar5ten:
The difference doesnt matter .

If you install alot of crap on your device you will have less free ram.

If you install nothing you got more free ram.

[Xiaomi Mi 4C] jonasb_dk:
You should be able to do a dirty flash, as long as it's the same Android version you're using. But as always, backup! ;)

But yes, you would need to flash SuperSU in order to gain root access again.

---------- Post added at 11:09 PM ---------- Previous post was at 11:01 PM ----------

I think there is a non-touch version on the Chinese forum I think. I am not completely sure about it. But if you have a lock pattern on it, they won't be able to access the phone, and if you encrypt your phone, as you can do in the settings, then they won't even be able to see the content of the phone at all... I think that's more safe for you.

You're right though - that not all pick pockets are hackers - but, their friends are and they will not matter what, be able to erase and take stuff from your phone if they want to. You just need Google and your set - and seriously "fastboot flash recovery touch-recovery.img" is not that difficult for n00bs either.

But why worry about a thief? It's a cheap phone, and it would hardly be of any relevance to pick pockets, they only take changes on phone they can get a decent price for.

Do you guys think the Mi5 is worth waiting for?

I'm very nervous about the mi4c. I'm not sure it will ever get the support that the main Mi phones do. I just saw that mi3 , mi4 and mi4i will get marshmallow, but there has been no news on the mi4c
[Xiaomi Mi 4C] Prettygrim:
hi all. i'm in need of some serious help, if you learned people dont mind.

i'm pretty useless with phones but after getting my Mi4c i decided i wanted it rooted. a friend is much better than i with these things but unfortunately was unable to help. i read and read and eventually somewhow managed to get the phone rooted. it appears i also got TWRP as well. anyway, today i was asked to update SuperSU and did i want to do it through TWRP. i said yes and everything is now useless! the phone wouldn't do anything at all, so tried to get TWRP to run. i did this but regardless of what else i do, only TWRP loads up. i have tried wiping cache, dalvik cache, removing everything i could so that i cant do anything else until i load an O/S and still the only thing that comes on screen is TWRP.

can someone pls guide me as to how to completely wipe the phone, so TWRP doesn't actually load, and then help me get the O/S back on? i'd be extremely grateful for the help

many TIA
[Xiaomi Mi 4C] gtfour88:
You need to flash a rom from TWRP. Which rom do you want to use? There are MIUI 7 stable, MIUI 7 developer, sMIUI, Mokee, CM12.1 and CM13. Apologies if I have missed any.
[Xiaomi Mi 4C] Prettygrim:
many tnx for the reply, gtfour88. i have been doing that as it's the only way to get a rom on the phone but after it tells me 'success', which i assume means the rom has been installed, it then makes no difference if i reboot or do a clean of cache/dalvik cache, whichever is offered, then reboot, up comes TWRP again! for whatever reason, only TWRP is available. it seems that nothing can get past it, so the system wont boot. any other suggestions or does it mean sending the phone back, which i obviously dont want to do?
[Xiaomi Mi 4C] gtfour88:
This never happened to my 4c. What about try to flash / fastboot a different TWRP version (I believe there are a few around) and then flash a rom again. Not sure if it will work but worth a try.
[Xiaomi Mi 4C] Prettygrim:
i'll give it a try and post back. tnx for the suggestion. the issue appears to be either not being able to remove TWRP, not being able to bypass it to get a proper boot or not being able to completely wipe the phone.
[Xiaomi Mi 4C] Prettygrim:
i didn't manage to achieve anything so spent more time hunting around for a solution. luckily, i found out how to get TWRP off the phone while flashing a rom on. that worked! the next thing was trying to get a newer rom installed and again, that proved to be quite a trial! i followed the info and did the same thing 3 times without success. 4th time lucky and we are up and running. now i need to get the phone rooted without screwing it up! that is going to prove interesting, but i think i will wait until tomorrow. hopefully i'll have a clearer head and not mess up this time.

as an afterthought, would CWM be a better option than TWRP? as i am new to it, i have little knowledge of this side of things either.
[Xiaomi Mi 4C] gtfour88:
I have not seen a CWM recovery available for the Mi4C yet, but I have not looked hard enough. Happy New Year to everybody.
[Xiaomi Mi 4C] Prettygrim:
i'll keep my eyes open and hope i find that CWM is suitable. in the mean time, i guess i'll have to try TWRP again. to save all the grief i just had, a good idea will be a complete backup of how the phone is atm. at least then i should be able to recover it if things go south. what will be the best solution to do that, remembering i dont have 'root' and need to backup everything?
[Xiaomi Mi 4C] oldcpu:
How to obtain Root access with MIUI developer ROM ?

I successfully updated the firmware with the MIUI developer ROM from http://en.miui.com/download-293.html using the 'updater' application on the phone, selecting the "developer ROM" from that site (I had to place that ZIP file on the root of the phone first). I had thought this update would provide root access but under security -> permissions > root access the Mi 4c still has the phone listed as not having root access. Is there something additional I need to do ?

I do have to say that the MIUI developer ROM is an improvement over the ROM that came with the phone (custom ROM from Giztop), with the possible exception being the phone now only has Chinese and English language.

Previously (before this new ROM), the ROM that came with the phone would constantly have popup advertisements (originating from a non-removeable 'search' application) and it would randomly automatically install unwanted applications. With the MIUI ROM this mal behavour has stopped.

When installing the developer ROM I both cleared 'cache' and cleared 'data' (removing all previous applications). To install Google playstore I needed to install

* Google Play Store

* Goolg Play Services

* Google Services Framework

* Google Account Manager

However I would still like to root the phone - and I suspect I am missing something obvious to obtain root permissions ?

Must I next install another application to obtain root ?

.
[Xiaomi Mi 4C] rob rich:
The developer Rom has root built in. Its in the Security App under Permissions. But you first have to start your App which needs root, to show it in Security App :)

Thanks! Indeed that was the case - the behaviour was different than I had expected and hence I did not appreciate that indeed my updated Mi 4c (with the developer ROM) did have root access. Your gentle push in the right direction was exactly what I needed.

What ROM do I have

I've just bought a Mi4c from Geekbuying and they have installed Google Play/Services and said they would install in international ROM too which appears to be the case since all the apps are in english and there aren't any Chinese ones apart from Xiaomi ones

In the phone settings it says the MIUI version I have is MIUI 7 55.12.31 | Beta - is anyone able to tell me what ROM I have (eg MIUI itself, sMIUI, EU MIUI etc) and therefore how I go about updating it if/when I need to??
