[need help] - Problem with cellular reception - Xiaomi Redmi Note 4 Questions & Answers

Since miui has been updated to 8.5, it has a very weak reception and at home it does not work at all.
I changed the SIM of 2 different companies and in addition to other phones it works.

maybe it is the miui's problem
im in China and i can provide you miui Chinese edition if you want and there are almost no bugs!
in China it's already updated to 9.1 and it is really powerful

[Q] New X1 owner, 4.4.2 rom and model help please

Picked up a second hand X1 and trying to work out which model it is. Having a few issues with 3g-2g switching and signal strength and want to make sure I have the best ROM installed.
Attached is the one it came with, everything is fine except the signal sometimes drops out all together even though my Samsung Mega 6.3 has 3 bars of 3G and 4 of 2G in the same location.
Bluetooth also seems to be a bit flakey with my LG Google watch sometimes disconnecting.
Turning Bluetooth on and off fixes it but its not a real solution as I need it for notifications. I also need to stick with 4.4.2 for my Google watch to work.
Any suggestions? Is this a stock rom?
the rom installed on your device is the latest for the 7D-503L ( Huawei Honor X1). wich means it's supposed to be the more advanced ROM for this specific one.
To check if your device is also a 7D-503L, look at the back of it, the model number is printed at the bottom, even if it'sprinted in chinese.
No model number printed anywhere, guessing its the Chinese version. Bad 2G/3G reception is driving me crazy on this thing, not much use as a phone if I can't get receptions.
Callers sometimes have to wait a couple of seconds before they can hear my voice too which is really embarrassing. I might try an earlier rom, looks like I am on some beta version.

Try to install the last international ROM (B102 for 7D-501L, will go to b103 by OTA after install) adpated to the 7D-503L:

your you can try the 7D-503L B009 ROM, which is supposed to be the more signal-stable:

If the install fail for this last rom, it means that your model is not a 7D-503L
let us know

B009 sounds like its the best rom for this phone but its only 4.2 and I need 4.4 for my LG Android watch to work. There is a B010 out so I will try than next but I am not hopeful.
Pretty sure the problem is with the switching between towers on low signal. I can go from 4 bars to no signal in an instant in the same location at home. I tried a different networks SIM card and still no good at home. The same SIM card in a cheap 2G phone and I get 3 bar and no drop outs.
How Huawei can get is so wrong is beyond me.
In the CBD today where there is good coverage I had no problem at all with calls or signal but on the train home it was useless.
The same trip with my Galaxy Mega 6.3 gives me pretty good connection and data all the way home. I love this phone but I will have to go back to my Galaxy Mega if I can't resolve this signal issue.
B009 is KitKat 4.4.2, 400 DPI, EMUI 3.0 .
Install this ROM. (and then check if your device is a 503L, revealed by achieving the installation)
If still signal issues, try the 501L B102 adapted to 503L.

New carrier not included in 5.1.1 build 14 JustArchi

Hello everyone!
I'm a great fan of JustArchi and his work in our i9300 and I've been testing all his work for i9300.
Recently, i've changed to a new carrier that has appeared in Spain, called Tuenti ( property of Telefónica/Movistar). Using JustArchi's ROM, i've noriced that i have to activate Roaming in the same country, to use Internet, and i can't see different qualities of network speed (G,E,H,H+ and so on), I only see R.
Surfing the Internet, I've discovered that this issue is due to a non-updated OS of carriers. I wonder what can I do to help JustArchi to incluye this new Spanish carrier in the ROM to solve this issue.
Thanks everyone, and sorry for posting here, but I can't post in Q&A in the proper threat.

Simultaneous 4G/3G Dual Sim

Hi,
I'm new to the forums and this is my first post. I've been using RR Official on Radon for a few months now though, constantly updating along the way. I find my biggest concern right now to be having simultaneous 4G/3G on dual sim instead of 4G/2G as 2G is not an option in many countries.
I'm currently on RR 5.7.4 10192016, Radon Kernel 2.9.5, and CM 14 Firmware, which somehow allows me to have simultaneous 3G/3G, but for some reason both of the strength of their signals are always equal to one another despite being connected to different telcos, if one goes up the other goes up and if one goes down the other goes down (so I am doubting that it is true simultaneous dual sim 3G). For some reason neither of them can switch to 4G either, which I had access to before switching to CM14 firmware from CM13 firmware (which could only do 4G/2G).
I read in a whirlpool forum that MIUI added simultaneous 4G/3G for our device quietly and was wondering if any of the current custom ROMs/firmwares/Kernels allowed for this as I really need this feature and would prefer not to go back to MIUI.
I have the links to the forum, but unfortunately can't post it, being a new user.
Thanks.

Wifi calling / Vowifi rom please

Hi guys.
Is there any rom which has Vowifi(wifi calling) for redmi note 3 kenzo or is wifi calling something hardware related and not possible to get on this mobile?
Does wifi calling need to be supported for particular device models by cellular service providers because if that is true then the cellular service providers in my country dont show redmi note 3 in supported devices on their websites and i cant get it or is there a workaround to trick them into thinking this is some other device which is supported?
Thanks in advance.

I was the proud owner of a Kenzo for many years (in the UK) but after I moved home to a very weak mobile signal area I spent many hours searchinfg for a VoWiFi solution without success - so I reluctantly recently sold it :- (
I learned that MIUI never incorporated the necessary code into the firmware (this is not the ROM). And I never could find a developer that had been prepared to modifiy the code to allow VoWiFi. Also note the modification has to be compatible with the networks in your country.
You will see many recent custom Kenzo ROMs with VoWiFi switches - but it will not work without the non existent firmware mod.
Sorry.

ColorOS 11 is rolling out in France

Got a carrier-buyed (Orange France) FX2Pro on CPH2025_11_A.46 (October Security patch) and was proposed ColorOS 11 v.CPH2025NV4A_11_C.57 (although it seems that the server used is a Chineese one, as the download is tidiously slow, 3G in 2h with a fiber-backed wifi that goes to speeds around 500/500)
I also bought my FX2P from Orange France (but they don't lock the phone or use specific carrier ROM), and I'm still stuck on CPH2025_11_A.50.
It seems the rollout is slow to reach all the serial numbers.
Hope the update will come quickly to my phone.
French team too waiting for color os 11 on my unlocked x2 Pro... A50
