hi,
since few days I got the following issue :
when the 3g connection is on, I cannot receive (or I cannot make) any phone call as the device completely loses the operator signal and some times I have to reboot it to restore the gsm signal. I noticed tha this happens only when the status bar displays "3g" icon, when in " H+" it works properly.
I put the sim card in a different device and it works, so it is not a network problem.
the problem is that I got this issue with a custom rom ( lg stock based) and then I flashed cyano 11, but the 3g issue is still there!
Could it be an hardware problem?
Has anybody any Idea how to solve?
thanks
What kernel you use?
I've been using some customROMs and never had this problem.
Try a factory reset, flash again KDZ and try other customROM, like BeanStalk and test another kernel (I prefer iodak 9.95)
The only way to find out if it is a hardware problem is testing.
Best Regards. :fingers-crossed:
There has been a discussion about this already somewhere, I remember @Flying_Bear participated too. For me personally network doesn't work at all (no calls, texts or data) if it's displaying 3G, no matter which roms I use. On H or H+ it's working properly.

I tried everithing: different kernels different custom rom, different original stock firmware...nothing: can we consider it some HW issue?
Hello,
I don't know if anyone else is facing this problem or not but i've spotted this issue in my Mi3. Neither 3G nor 2G works properly on my MI3. In 3G the network keeps shuffling between H and H+. When the indicator turns H+, i can surf the internet and when it turns H, i can't. I tried the same sim in my Xperia ZL and 3G worked like a charm. No disconnection at all.
Tried using 2G and facing the same issue. It'll work fine for say a minute or 2, and then the indicator shows the up arrow (data sending) and there is no down arrow( data receiving).
If anyone has any suggestions please do share.
Thanks in advance.

Hello...
Facing same problem in MI3. Got annoyed. I had changed network initially to see data works but i think there is some issue in MI3. Xiaomi need to take care ASAP.

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts
hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?
Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.
hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?
Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).
this is easy.
root then disable LTE band 41

How do you disable band 41?
Thank you in advance.
easy way > install network signal guru > 3 dots (menu) > lock bands > lte > uncheck b41 tdd 2500.
Hi, I flashed my Mi5 from miui 8 to LineageOS Nougat a week and half ago. I have the latest update which is dropped since April, 11th
Rom is very nice, but I have a huge problem. My operator is a French operator (I'm from France). Its name is "Free".
When I was under miui I had all the time either 4G or 3G when mobile datas were activated
Now since I am under LineageOS, I'm almost always in H and very rarely LTE. I never have "3G/4G". I don't really care about the name, but my mobile datas suck... I mean pages are very slow to load, like it should be in H.
I thought It was a problem from my operator but a friend of mine and I went together at the cinema yesterday and we have the same operator. He was in 4G and had a very nice network.
Mine wasn't able to load Google and I was H... (And he's got a UMI Touch running Marshallow Stock ROM)
What's the issue? Can you help me ? (We got the same Access point names defined)
Thanks, best regards.
Up... Haven't found a fix yet
Change your network settings under sim settings to "Global". Also if you are having network connection issues, try to change your APN.
Hi
Recently updated my dev to final build of Pie , screen's attached , am getting very poor network coverage in most of the locations and getting decent coverage in some . Same s happening with WiFi also , is it because of our specs are outdated comparing with others or is it me having modem or firmware with poor features .
Sim 1 Airtel with Volte
Sim 2 BSNL
No, it's just a visual calibration issue/difference between the ROMs. There's actually no difference in physical signal strength of you look under the hood.
