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

Sorted!! I made a hard reset... Which led to a bootloop. Fixed turning phone off volume up+home+power . Clear everything and reboot... Voila now works like a charm hope this helps otgers in my situation
Hello everyone, i'm asking this because it's the third time i had this issue. I often keep my Data Network Mode deactivated and turn it on only when i need because of my 3g plan (quota, taxes, and also because it's likely to find a WiFi network in the places i usually go).
The problem is, sometimes i turn on 3g (by Phone options menu) and... nothing happens... i need to reboot to make it work again.
The 3G network in my country is quite unstable, but i'm pretty sure that isn't a signal problem because one of the times i was turning on/off the 3G to make it work and i gave up and forgot to turn it off, the next day when i tried again i found it was On but not connected. After a reboot, working again.
Anyone having this issue who found a fix? Could be a problem with the kernel or app?
Edit: I Forgot: CF-ROOT Kernel, KF3

mate i am afraid you have answer already - "The 3G network in my country is quite unstable"
that can clearly produce the bug. Just in the case check your APN settings if they are correct. Settings- wireless and network-mobile networks- access Poin Names - compare the stats there with your network provider and make deep research.
just example i am on vodafone - i found that i was running vodafone live profile in APN and i was loosing conexion and i had troubles loading some pages - after research i found that there is another setup for vodafone as well - different then the live but for vodafone as well. i am using it since then and i am experiencing now the lighting speed of 3g. Just give it a try.
Searching on the internet i found that the configuration of my APN is equal to the recommended.
Backup data and factory reset phone should clear any software problems .
You could try flashing KH3 modem .

Same issue here for both rooted and un-rooted GS2
Retracted - will have to do more testing
I'm currently in bahrain the problem and I'm using SGS2 for 3 months and I'm having this problem
the problem is when the phone in idle it will switch automatically to 3G and when I'm going to use it lets say I'm going to open WHATSAPP or CHATON it will connect to H or H+ if its available .. the problem is when its trying to change from 3G to H+ its not going to get data like the green arrow will get stuck and it will try to connect ... this problem happens only in the chat application like whatsapp + kik + chaton when i write anything its not going to deliver (not every time) but most of the time ..
i wiped the device .. i wiped everything .. i tried every single modem ! i tried many rooms .. i tried to change the CSC ... i disabled fast dormancy .. i disabled hsdpa with this code *#301279# to 3g only .. i changed the band using *#*#4636#*#* !!
i did everything i guess and I'm still having the same problem !!
i even called the carrier and they don't know anything about this problem and what is the reason !
is it a carrier problem? i was using iPhone with 3G connection it was working fine

I am with you on this one. Same problem, upload arrow stuck, no connection. Sometimes when this happen, I can use browser without problem, but no luck with application trying to use data. Sometimes it's just completely dead for both browser and applications. I am on STOCK KI3 ROM, KI3 MODEM. I had this issue from KF4 up. I also tried all the potential fixes, but still get this issue occasionally. When the 3G network got stuck, battery drain like hell. Maybe apps are in the loop of trying to get connection.
Any solution !?
Please Help

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.

Hello from Bahrain
I ll suggest you to use this Great room "OlloSII MoNsTeR" ICS XWLPG i ve no problems and its working gr8 best battery life and very fast/stable.
Hi guys need a bit help with internet connection and gtalk. I know as far as I read that there are problems with disconnecting gtalk which might be the issue with correct apns. When I'm on wi fi everything works fine but when the phone is connected to network it's automatically disconnecting which is very annoying because I'm not getting all the messages.
My question is if anyone found a solution to solve this problem or maybe someone can share the apn settings for 3 sweden so that I can check if it's working. I'm on a stock 2.3.5 firmware + cf root.
Thanks

the rest of the apps work fine on 3g? if yes, then i believe the app might be the problem
if not the it must be the network, i would try with another modem or just call and ask them wth is going on
Thanks for a replay, actually I tried everything software related and nothing has helped. All apps work fine but thats not app related thing cause once I put the software from a scratch (wipe everything even internal memory and sd card) and it was the same. Today I started experimenting with apns and I see the progress.
Also as I am on 3 network dont know why the default setup is gsm\wcdma? As far as I know they don't provide gsm signal only 3g. Never mind every time I tried to change to wcdma only it was going back imidiatelly to previous state.
Just an hour ago I discover code to force the setup to run only wcdma and hopefuly that will solve my problem. We will see
Anyone from Sweden on 3 network has the same problem?
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

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
wont u brick your fone if u flash ofw from recovery?
try this in TWRP go to MOUNT there you'll see a option "mount system as read-only" un-check that box and try flashing the rom..
i also have unclocked bootlader will it get bricked if i install it using the update app
