I've purchased Redmi Note 3 Pro a few days ago. I'm satisfied with overall of the phone but there is one problem I'm facing.
After I quit airplane mode(every night I turns on airplane mode before sleep then turns it off in the morning), my phone won't detect the network most of the time, sometimes it detects the network but it took way too long to happen but still, it acts like there's no network. I couldn't call, sms, receive call, receive sms and use mobile data. Everytime I have to restart my phone to detect the network.
Is there any ways to fix this problem ? It irritates me a lot as I have to restart my phone everyday.
update your phone, this issue has been solved about a month ago
Yeah the new builds are much beter
Hi guys,
I also have network problems on my Note 3 Pro - but without airplane mode. My phone just randomly looses internet connectivity, sometimes completely, sometimes it drops to Edge, most of the times with a warning about roaming and data connectivity. And yet sometimes I completely loose mobile signal but a on/off airplane mode fixes it.
It's pretty irritating, I didn't have these sort of problems with my prev. phone, and I haven't visited any new places or with bad reception.
I'm running the 7.1.8.0 global stable rom.
PS: My locale is missing, and I chose Argentina on random, then disabled auto-time. Could this mess things up ?
Any input would be appreciated.

I am facing a terrible network problem with my phone too. I have used China and Global ROMs and I cannot fix the problem. I am currently using Global 7.1.8.0
My phone does not respond to incoming calls when in sleep mode. Incoming calls go directly to voicemail. It seems that it is connected to the network while in sleep mode. However, it does not respond to the incoming call.
If the phone is awake with the screen on, it shows an incoming call.
I have tested other SIM cards, switching from 3G to 2G, reseting the phone, clearing cache, disabling "do not disturb".... The problem just does not go away. It's a shame that a phone with this much potential has a basic problem like this.

Just tested, mine rings when sleeping. But define sleeping... ? When display is off for a some time ?
I am also suspecting something with the sleep mode, it usually 'switches' to Edge or no connection while in my pocket. I am also suspecting problems with the sim card, have you tried with a new one, or card in another phone ?
Otherwise I really like the phone It brought my trust back in Android.
edit: Update > Download Update and it started downloading, then restarted, installed something, but I'm still on 7.1.8.0 ...
Auto download is ON.

I define the "sleeping mode' as phone with screen off for some time. I tried different SIM cards and from different network companies (3 and Vodafone). Same problem. My network signal is extremely unstable. I like the phone a lot too. However, network signal is something so basic on a phone that it is a shame it does not work properly.
I am also facing similar issues but xiaomi people are not recognizing the issue. They are telling that it's an isolated issue. Please post here, so that they fix this problem.
http://en.miui.com/thread-255747-1-1.html
I got a new sim card, and upgraded my plan, now I have good reception, almost always LTE, sometimes drops to H+. How I miss calls when my phone's display is turned off/sleeping. I'm getting pretty pissed of with Xiaomi about this ****
So annoying
Hope we get the 7.2.2 update soon and it fixes this problem
What good is a phone if it has network issues

Got my phone yesterday and had the same problem this morning. Solved by signing out of my MI account, switching off VoLTE and rebooting. Everything works properly now. Hope this helps.

Forget my previous posts on this issue. Follow these steps as they worked perfectly for me and I had to repeat them this evening since I did a reboot.
1. Keep sim registration on automatic on both sims.
2. Power off phone.
3. Remove sim 1 and keep sim 2 (my sim 2 is 3 Mobile UK roaming. That may make a difference).
4. Power on phone. My roaming sim 2 registers immediately.
5. Power off phone.
6. Insert sim 1 (primary or local sim).
7. Power on and you should have both sims working perfectly.
8. Go to sim settings and change your preferred calls and data back to sim 1 if you need to.
These steps have worked for me twice so far. Hope it helps.
P. S. I must add that I have zero, zilch, nada issues with my Zenfone 2 running the same setup (local sim and uk T-Mobile). Love the Xiaomi so far but detest the lack of native alphabetical for the apps. Considered Nova but the free version doesn't give message counters. Any suggestions?
There is a temporary trick posted at http://en.miui.com/forum.php?mod=viewthread&tid=251620&page=1#pid4736228
I was having network problems and it seems to be much better (perhaps solved) with this trick.

I am glad it helped you. Make sure you type the code *#*#995995#*#* twice after stopping the apk. I actually disabled this apk without any secondary problem.
I am running Global ROM 7.1.8.0. Still waiting for 7.2.2. Let's hope this problem will be fixed in the next update.
Hi,
I'm also facing network issues with 7.1.8.0 : when exiting airplane mode or switching from Wi-Fi to gsm network, I lose data connection. The only way to get data back is to reboot the phone.
Sadly, the trick from miui forum didn't work for me for this particular problem.
Il hope this problem will be fixed in 7.2.2.0 update.
@ mura20 : thanks for the trick nevertheless...
OTA 7.2.3.0 is here!
OTA 7.2.3.0 solved my problem !
Great
I also got the new ota. But how to flash? Twrp returns error 7 when I try to flash

First of all i must apologize for not posting on development but im not allowed since this is a new account on xda...I live in London but im in mallorca spain for the summer looking for a job so having a phone is very important. As soon as i got my sgs2 i rooted it .. i was having some issues (random reboots) which led me to think it was either something wrong with the unstable kernel i was using or more likely a bye bye RAM. I decided to reset the phone and installed the LIGHTENING ROM... I Just love it!!! but... now im having trouble with it ... (BIG TIME) I had not realized something was wrong because everything seemed fine until i asked my gf to call me today... she couldnt... then i tried several times myself without success. I rebooted and to my surprise i started receiving a lot of work calls!!! (Which is great) but then i tried calling myself and it didnt work again. Im going back to stock firmware for now since the device is a phone after all. Dont know just yet if this will fix it but ill keep you guys posted... anyone having similar issues??
It might be a small bug in your firmware, try reflashing Stock and then see.. If still the same problem, try stock firmware from another source and reflash.. if still the same problem.. then its a issue.. Post your findings.. please
I have no issue like that.. just trying to help

check if your internet connection is set to wcdma/gsm auto mode...i am having similar problem when it is set to wcdma/gsm auto..it keeps loosing connection and radio switches off...making my phone unreachable most of the time.setting it to gsm only is the only way to cure this at the moment for me.

hi iznee;
I am from malaysia too.
currently I am using stock KE2 ROM. just rooted the phone for some xtra things that I want to do with it.
my phone is set to wcdma/gsm auto connection and never have outgoing/incoming call problem. Data also works as expected and by the way I am subcribed to Celcom unlimited Data plan.
by switching to GSM only, you are limiting the speed ability of the data to GPRS/EDGE only. please noted that you cannot have voice and data simultaneously while in GSM only mode. your Data session will be suspended if you make an outgoing call or if you receive an incoming call.
however, if you set it to WCDMA only, you can have both Data and voice simulataneously and that explain for 3G video call. but, not all areas are covered by 3G thus, if you entering an area without 3G, your phone is useless because there will be no signal.
if you set it to WCDMA/GSM auto, the phone will switch to GSM when there are no 3G signal available and that will ensure smooth phoneoperation in making/receiving call.
After a week of usage, I can confirm to you that I never have outgoing/incoMing call.problem and no data.problem.

Well so far my findings are null. i flashed kd2 stock with odin with the re-partition parameter on. Nothing happened. Was thinking re-partition would actually get rid of all the apps in case something there was giving problems... the phone was working fine when i was in england with kd1 stock... (How do i get rid of everything and start from scratch?? and what does the efs option do?? im tempted to use it xD) ... One other thing is i read somewhere that kd2 was giving trouble on orange uk (im ukthree but have tried with vodafone spain simcard) any ideas???
Efs is your IMEI code etc.
Backup as per post dev section .

iznee,
I have done a test regarding call in/out and also data connection. below are the test;
I am driving from KL to JB and crossing 5 states (KL, Selangor, N.Sembilan, Melaka and Johor). Along the 400km routes, I have taken the NorthSouth Highway, federal trunk road and also state road. My phone will change from H/3G to E/G when the signal is not available and I've no call drop whatsoever. I made calls while 3G/H signal is strong and also received calls. I did use the google maps.so that the data connection will be.continuous. In 3G/H mode, I can make/receive calls while the maps constantly refreshing based on my driving location.
when I enter the are without 3G, the phone automatically switched to GSM mode. albeit a bit slow.in data.connection, the maps still refresh without fail. when I make an outgoing call, the maps will stop refreshing as this is the behavior of GSM that voice call will take.charge and data will be suspended until I hangup the call then the data automatically resume its connection and the map refresh automatically showing my driving location. Then I use my other phone and call my SGS2 and as expected, the voice call going in and data suspended temporarily.
after hangup, data resume again and the map refresh automatically.
and when 3G signal is available, the phone automatically switch to 3G/H mode again and vice versa along the route.
all in all, I can say that my SGS2 works wonderfully and meets my expectation that phone function is priority. sattelite locks will take no.more than 10s and sometimes just under 2s. Superb performance by the phone.
Camera wise, no complain as I am.not a proffesional photographer. and I am more than happy for the camera performance.
Battery wise, no complain as I have unlimited data so i have all.my Facebook, twitter, push mail, livescore, news, weather etc ON 24hours. anyway, I have vehicle charger with me so the phone will be charged as long as I am driving.
this is from the about of the phone;
Android version: 2.3.3
Baseband: I9100XXKDJ
Kernel: 2.6.35.7-I9100XXWKE2 - CL187606 [email protected] #2

I've been having some issues that i wasn't having before. I've got the OPX for about a month now and it is connected through LTE but i can't access internet.
If i turn airplane mode on and then off, it works for about a minute or so, then stops to work.
Anyone experiencing this?
Everything is ok here no problem yet

check apn's
APNs are there and they are well defined, I have manually redefined them now -> Airplane Mode on -> wait a few seconds -> Airplane mode Off -> surfed reddit for a minute or two, all of a sudden "This page cannot be displayed: 'ERR_TIMED_OUT' "
I would think this is a network problem, but there is a forum thread in oneplus forums where people are complaining about the same as me, although they associate the problem to Wifi and i don't
Also, i don't know if it's related, but I've flashed the latest version from MasterAwesome, the problems started there, i thought it was from the ROM, so i then flashed OOS2.1.3-x, where i had the same problem, then 2.1.2 and still the same issue...
I'm getting something like that issue but very rarely and mostly on WiFi. It comes between sleep and awake states so maybe check out greenify and see if that is the culprit. Or any other app that's restricting any function through the waking of the phone.
My oneplus x detects wifi very well, but does not connect to mobile data. What could be the problem?
Uh I have a similar issue but usually when I'm in motion. (in guessing switching between cell towers) what's your network. I'm using Tmobile US

Same problem I had yesterday. Must have tried 10 ROM's all of them flashed fine and everything worked except cellular data. I had no data what so ever. As soon as I flashed back to stock ROM data worked fine. So there must be a step or something we've missed in flashing custom ROM's spent all day yesterday trying to figure it out with no luck. Finally gave up and went back to stock. I'll wait for the official OTA marshmallow update from Oneplus
I'm having this issue right now with full 100% stock. Does any of you have the problem solved?
Just wiped data + cache + factory reset, but still no luck. I've also created a ticket on OnePlus support.

Are you using 2 SIMs? Data does not work for me on SIM 2 Slot but works fine on SIM 1.
I also can't connect to mobile data. There is no LATE/4G icon in the status bar but if I pull down the notification panel, LTE appears above the network icon. I've tried in both SIM slots. None of them work. The SIM card works fine on other phones.

Hi,
I have serious issues with my H7.
Since 1 month or so i can't take any phone calls, or do, i have network issues like "emergency call only" or "no services". I have to resend texts very often, and i have issues going on the internet with 4G or 3G.
I flashed several updates, updated with OTA from B130 to B330 and i have still the issues.
I have no emei issue, and the modem should be replace every time i flash a new update so i guess its not the issue here.
I have mainly this issue while travelling but even going to the toilet make it happen.
I realy need to take phone calls so i realy need help :/
Thanks !
Hi,
the same issue over here: my Honor 7 used to be ok with EMUI 3.1, build PLK-L01C432B180, Android 5.0.2.
After update to EMUI 4.0, build PLK-L01C432B371, Android 6.0 it started to lose connectivity, there were time periods having "emergency calls only" or "no service" displayed. During that time no calls can be received (it still persists).
I do not know the fix for this, but you can try to limit your network mode from "4G/3G/2G auto" down to "3G/2G auto" or "2G only" this way:
Settings, More, Mobile network, Preferred network type
During the time I was trying this, I didn't experience the above issue.
Hope this helps.

Did you:
1- backup all your stuff with native Huawei Backup, including screen layout?
2- factory reset
3- gone through setup wizard and check connectivity
4- restore backup
The most common cause after an update is not having a facotry reset (cleans old files). Please post your results.

Hi,
many thanks for your questions.
Well, maybe a bad (more time consuming approach) from my side, but no, before update start I only made an offline backup of my contacts, thinking the rest can be set up again, when needed.
After update there were some GPS related issues too, but at the end it has turned out, that it wasn't because of GPS but waze: it wasn't able to find GPS signal whilst maps.me has just woked fine. This has been "fixed" via waze uninstall/reinstall.
To come back to your question, yes, after a while I did a full factory reset hoping that it will solve the (maybe LTE related?) issues, but there was no change at the end.
Kind regards,
H.

Did you try to move your SIM card from one slot to the other?
Also did you experienced the same symptoms with other SIM cards? Just to exclude SIM card reader issues...

I'm in same boat, but I have issues (ajnd have mentioned it several times) with 4G rather than calls. My phone also sits in 3G/2G mode and is fine, but worked perfectly well with Lollipop.
I would try swapping the sim slots, but can't as I need the memory card usage, and I'm not wanting to butcher a sim card to do that hack.

Rule out first any SIM reading issues.
As for the butcher, usually if you say your SIM was lost, they will provide you a new one free of charge. So you can do some experiments.
It´s actually very easy.
Problem occurs with stock Rom. And I already tried CM11 and others ROMs.
When I turn on the phone, everything work great, both SIM registered, calls working, 3G connection. But after hours using (sometime 2 hours, sometime 6 hours aleatory) the signal indicator remain showing full signal, but is showed on "about" that network and phone number is unknown but still show type of signal (3G, Edge, UTMS). On both SIMs. Emergency calls only. Is like that could not read the SIMs card. And I can´t receive calls or make calls of connect on 3G. So, when I realize the problem I restart the phone and it come normal for hours. Airplane mode don´t fix, just restart.
I Already tried with stock BUBUANH1 (my phone is GT-i8552B) and BUBUANF1.
I believe that is a soft problem because my wife have same phone (both are after jul 14) and the problem occurs in both. I think very improbable to be hardware problem in two phones.
On my mind, this problem always occurred in the past, but I don´t had identified yet. The SIMs card were tested on gt6313 and worked well for 2 days.
I going crazy with this.
Could you tell what can fix it? i already searched for the modem.bin to this phone but cant find, anyway i think that if it was the problem it would never works.
First time when I used odin to flash, I chosed Phone instead PDA and flashed the stock tar file. The phone get a loop, but after I flashed using PDA the phone worked fine. Could this to be the cause? Could corrupted some thing?
I tried to changed APN manually to rogers but still data does not work, only call and text works. Is there a solution to this? I believe i got Pro 2 (cn with global rom installed)
I had the same issue, below is the APN setting on Rogers website, I've found that if you make the following changes, it will connect to 4G data (until you restart your device)APN Type: replace "internet + mms" with "*"
MVNO: ROGERS
MVNO type: SPN
This will get you connected.
However, I ran into another problem after configuring the network this way. After restarting the device, the phone can no longer detect the SIM card, and has an error message prompting restart).
This is my problem after restarting:
Comparing with other phones, the auto detected APN Type is typically "default", but entering default will cause the connection issue right away. The "*" will allow you to run until device reboot.
I too would like help on how to resolve this. Seems more software than hardware problem since it only fails after boot.

I just tried your method looks like it works and as you said it doesn't work after reboot. However when I did "Network setting reset," I was able to connect to 4g again (but resets wifi passwords too). Hopefully there's a solution...
I noticed that this problem only happens if there is a SAVED wifi network WHEN the device BOOT up.
I did a factory reset, then enter the APN manually. I was able to connect to stable network.
I did a system restart, no issue. The phone reconnects to the network automatically after booting.
I connect to a wifi network. The phone still works fine.
I restart the device again, the problem comes back.
If I take out the SIM and only use the Wifi, the phone is also okay.
The only time when it doesn't work is when I have both, which is the normal use case.
Something is happening in the firmware between the wifi and the SIM during the boot sequence.
This problem exists on my Lenovo L70081, Legion Phone Duel 2 Pro, running OS 12.5.188 ST, updated using Rescue and Smart Assistant v5.8.0.25
Any help would be appreciated.

Im on the same OS version 12.5.188ST, my phone connected to data absolutely fine with no problems but after every few hours stop making or receiving calls. I did the following and its fine for some time now but I'm not sure whether this will work with every phone but no harm in trying :
settings.....cellular network and sim.....5G mode. By default (at least in my phone) it is on NSA, I first switched to NSA+SA but to no avail, than I switched to SA and vola problem solved, all incoming outgoing calls working bang on but I think now my phone doesn't go on 5g which is still not good but at least making calls as normal. Now, as I said, this procedure might not work for everyone but try it, cheers.

Thanks for the suggestion, unfortunately setting the 5G setting didn’t help. I also tried disabling 5G but I still have the issue.
Was your OS able to read the APN from your SIM or did you have to enter the APN manually also?

I didn't mess about with apn, as I said in my earlier post I had no problems using data its always connected but I had problems with making and receiving calls, cheers
There's currently two ROM available on Rescue and Smart Assistant:
L70081_ROW_SECURE_USER_Q00017.0_R_ROW_12.5.188_ST_210819_qpst
L70081_EE_SECURE_USER_Q00017.0_R_ROW_12.5.137_ST_210710_sec_qpst
What's the difference between ROW and EE rom?
Which would work best in Canada and US?
is ROW only updated in Asia and Pacific?
i sort of had this same problem with Tmobile. it would only connect to 3g . if i connected to the 4g or 5g network i lost everything . i was able to fix it using my ROOTED phone and an app in the playstore called network guru. I used that to turn off majority of the network bands and only left the ones listed for the phone. My service was immediately fixed and havent had any trouble since

I know how ya feel, I pestered TMobile for 2 weeks and they were no help. They kept trying to push me off to Lenovo who was absolutely no help at all. Id go thru their website which connects you to Motorola. Then they would tell me they don't support the phone because it's Lenovo and give me a link to follow. Id follow that link which led me right back to Motorola lmfao.
After 4-5 times of going thru that nonsense I finally got someone who knew what they were doing. They told me because this phone was never released in the US I need to go thru their European server for assistance. Screw that, I did some more research and got the idea of trying this from some ancient post I found on xda lol.
It's actually very easy as long as your phone is rooted. download the app, click the 3 dots and go into force control. Then adjust the carrier bands so only the ones supported by the phone are selected. Then reboot your phone and it should kick over to a working signal . If not ya might have to monkey around in the service menu using the dial code *#*#4636#*#*
Here's a few screenshots to give ya an idea and a link to a website with all the bands listed. https://www.kimovil.com/en/frequency-checker/US/lenovo-legion-2-pro
