[Q] Problems with Receiving SMS

Dear Samsung Focus users,
I really need your help and suggestions. I bought an unlocked samsung focus last week and I love it! But I have this problem:
- I cannot receive text messages until I reboot the phone
- After I reboot the phone, text messages will start flying in to my inbox
- Then the problem starts again and I have to reboot the phone to retrieve new text messages
I live in the basement but I have no trouble calling or sending and receiving SMS with my previous phone.
I hope it has something to do with the OS thus they can fix it.
Thanks!

Sometimes I get it where the device thinks it's on the network, but won't use cellular data or SMS. I'll see this after being in the basement for a few hours with a signal that fades in and out.
Try turning on Airplane mode, wait 5 seconds, and turn airplane mode off. It should reconnect to the network and start running again.
I've seen this on 'droids, WinMob 6, and on the iphone 3 as well. I've just sort of figured it was the radio chip giving up on retries. I could be wrong, but recycling the radio seems to work for me.

when you have no signal, the operator will keep trying several times during different time spaces until your phone gets it. the problem with focus is that they quit trying to received. i dont know but only works after a reboot. In other phones you just need to wait till next carrier push try. i think its a bug, probably to unlocked phones. I have an At&T unlocked focus.

I am having the exact same problem. I dont know what to do

Count me in.
I am also experiencing this issue.
Here are my thoughts on the issue.
1. I bought the phone from Rogers (GSM)
2. I bought an Unlock code from the web (SIM Unlock only)
- You know you're device is carrier locked if you cannot run Samsung's Network Profile App, or if it shows no other profiles in the list. The app is available on the marketplace.
3. I use the phone on SaskTel's 4G network (Saskatchewan UMTS/HSPA+)
Now my thought is this.
Whichever settings are not provided by SIM are set by the Network Profle xml that is specific to each carrier.
My assertion is that if you cannot change Network Profiles via Samsung's app, you cannot use your 'carrier free' (AKA SIM unlocked) device on another network without some hiccups.
If someone can figure out how to enable Samsung's Network Profile on a carrier purchased device, I'd be happy to hear how it's done.
I should also note that I've since developer unlocked via Chevron's WP7 tools with no change (Installed NoDo right after).
If someone knows what the network profile xml actually sets and can figure out an alternate way to set the settings..... ie Registry editor, etc. We would appreciate this.

[Q] Unlocked G2 on emergency calls mode only.

Hi all,
This is my case with the hope of getting any help or lead in order to solve my problem:
After a long research I bought an brand new LG D800 already sim unlocked in the US and brought it to my country (Costa Rica). I made sure the frequencies supported by the D800 are the ones used in my country. In fact 2 years ago I bought another phone that uses same frequencies and had had no problems ever.
As soon as getting in my country I placed the SIM card I'm using in my current phone into the G2 and it recognized the signal and connected to the operators network. I started to make and receive calls almost immediately, and also SMS' without issues. So I started to migrate all my data from the current phone into the G2. I used Titanium Backup for this, so I rooted first the phone using the guide I found here, and basically what I did is installed the apps from Google Play and then restored data using Titanium.
After the second day of use suddenly I found out that I wasn't able to make or receive calls since the phone lost connection to the operators network only allowing emergency calls but the signal bars were full (see scren capture). Sometimes when restarting the phone I get "Phone not allowed MM6" message just after the phone tries to connect to the operators network.
Went to the phone company offices and they tried to help me and made some simple tests, without changing anything inside, such as checking Android's network configurations, checking in their system to verify the IMEI wasn't blocked or reported (the IMEI is clean), also checked the sim configuration and after more than 45 minutes they were not able to find anything wrong in their system or with the phone itself. They also made a final test taking a working sim and put it into the G2 and gatting same emergency calls mode, and took my sim from the G2 and put it in another phone and that phone was able to make and receive calls. So they concluded that the phone has a "built-in" configuration or damage that impedes the phone to connect to the network. They finally suggested to ask the seller to apply the waranty, which is not a viable option since I'm not in the US anymore. This G2 is using the stock ROM (see screen captured).
I've been in close contact with the seller, and he had shown interest in this case but unfortunately hasn't been able to provide much support or help to solve the issue. He reports that he has contacted other buyers of this same phone, also sim unlocked by him, and they all are using their G2s normally. Didn't provide where their locations are tough.
My own conclusions here are that the G2 IMEI is not blocked by the phone company, that there is some kind of fault in the phone that when trying to connect to the network, the network doesn't "like" and rejects connection, althought it worked at the begining, and I'm not able to determine if the fault is software or it's in the hardware of the phone.
So I'm trying to understand what my options are at this moment:
Try to return the phone to the seller, or ask an LG representative in my country to change the unit. Which seems to be very difficult.
Reflash the unit with a stock ROM and reestablish the warranty. But being unsure if this will solve the issue.
Reflash the unit with a new ROM and loose the warranty, and again, being unsure the issue will be solved.
I'm really frustrated and at this moment and have no idea on what to do.
Any ideas or insight will be appreciated.
Thanks.
NOTE: I reinitialized the unit and lost any signal (see screenshots) but received update notifications from Google Play and was able to upload the screenshots into my Dropbox although no signal is shown in the status bar and no WiFi connection is established, only data connection thru APN (I Assume).

Go into status, what's IMEI say?
Sounds like EFS issues. I take it you didn't back it up after setting up on carrier and flashing?
Of so, you have some manual work to do with diag mode and a couple apps via pc.

Hi Steamer;
Under status I see 3 items:
1) Phone Number: shows"Unknown".
2) IMEI: shows the number printed on the box, on a sticker on phone's back.
3) IMEI SV: shows"03".
Where can I learn more about EFS issues? Are there tutorials?
As you say I haven't done any backup thing.

Hi again Steamer:
After reading quite a bit about EFS issues now I understand much better what you meant with your post.
And as you said I didn't back up efs folder, I even didn't flash any ROM yet in the unit. The only thing I did was a 'hard reset' to the unit using the Power + Vol. Down method, after having several 'com.android.phone' errors due to backing up data from Titanium.
The phone went to factory state, I put the sim card and everything went back to normal again, meaning that I was able to make and receive calls. Like 4 hours later the phone went to emergency calls only mode, and from then on I'm not able to take it out of that mode.
So I wonder if the efs folder could corrupt after that factory reset. Is it possible?
Thanks again and any light is greatly appreciated.

It is not in its own partition on this device, but in system. A hard reset shouldn't have caused corruption, but it is not impossible. Your IMEI is intact then, that is good. From what you said about it working partially, your EFS is most likely fine as well. There is a thread here to get files with custom recovery zip file, or you can use adb commands to do it yourself. I don't have guides off hand, but Google is your friend, just specified this phone in searches. Try a new SIM. Sounds more like SIM /carrier issue now as you are out of "activation". That is why emergency is popped and unknown number. The SIM itself may and most likely is bad(or carrier has an issue with your account), in turn it can't communicate with the server causing non activation on network search. Priority to SIM.

I had the same issues. Bought in Us using now in India. Go to settings..tethering&networks.. mobile networks... international data roaming and select standard data. Switch off and switch on your phone .
This will happen when you use, internet over gsm. If you disable internet or if your phone loses signal while switching between edge and 3g/4g data, this is tend to happen.

Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

No 3G signal at all, but not quite the same

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.

Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.

Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?

Soo no way to fix it? Should i give it for repair?

[Q] Need help - Unlocked Japanese Note 3 no longer works!

Hi All,
Please help. I'm a rookie at rooting and have an unlocked Japanese Note 3 through AU (my Japanese service provider). I was in a rush and paid someone to unlock it before heading back to the States last year. The phone works with my AT&T sim card but when I am back in Japan (with Japanese sim) I am constantly being dropped from the network. 4G service usually works for internet, etc, but I cannot make/receive phone calls and only occasionally can send/receive text messages. I need to know if I should re-root the phone (and leave it rooted) or just do a factory reset (or perhaps change some other setting to get things working again)? The problem with a factory reset is that it will probably re-lock the phone and I don't have a code.
Strange Detail:
Whenever I try to dial a number, the name of a Chinese Province shows up under the Contact's Name. This suggested to me some network issue where the phone somehow thinks it's in China (though texts still kinda work...) and doesn't connect correctly to the Japanese network.
Details:
Model: sm-N900J (per the download screen) i believe this means it has a SnapDragon Processor
Knox warranty has been tripped (apparently by the guy I paid to unlock it originally - is that bad?)
Android 4.3 (looks like I'm still in the original version of Jellybean. Should I upgrade to Kitkat or Lollipop?)
Other Issues:
As of two days ago, the phone now restarts after about 5 minutes of use. Like many Note 3 phones, it's always done the occasional random restart (another reason to root?) but now it's making the phone almost unusable. Also, since having the phone rooted/unlocked/re-rooted I always get a series of warnings upon start-up. Typically, standard Samsung apps like S Planner, Calendar Storage, Keyguard and Index Service have stopped. I have never been able to use the Calendar (or other basic apps) since it always crashes. Is this an issue with Knox clashing with something from the original root (I still see SuperSU loaded -but "turned off"- in the apps menu)?
Idealy...
...someone can help me decide the best course of action (Root, Reset, Other), and how to make sure I can connect back up to my Japanese network properly. I think I'd prefer to root since what I want is an unlocked phone that works smoothly, with good battery life, little to no bloatware, a custom theme and a working S pen. If I root, what's the best method (already have SuperSU apparently) and which ROM and version of Android would be the most stable?
Main Issues Recap:
No connection to phone network (or limited 4G internet).
Phone restarts every few minutes.
Many Apps crash upon Start-up.
Thanks in advance!

So, here's an update that someone with a similar problem might find useful...
Japan uses CDMA for voice and GSM for LTE Data. Somehow (probably through using my phone in the states on a GSM network) the phone was no longer connecting to the CDMA network. Since I'd gotten no responses and felt like there was a good chance that a factory reset would not reverse the sim-unlock I'd stupidly paid to have done, I did a factory reset. Despite appearing to have solved my Index Service, Calendar Storage, S Planner crashing issues, I was still having the exact same problem of LTE working but no CDMA network.
Somehow I stumbled on to this website...(well, I'm unable to post as a new user but searching for "How To Fix Samsung Galaxy error while searching for network" should bring it up).
There, I found some really odd directions that solve network error issues. The only part of the instructions I was really able to carry out was take out the battery and simultaneously press the home and power buttons 10 times. I restarted my phone and miraculously was able to place a call for the first time in a year in Japan!
But then I no longer had any data. I figured it had to do with the APN settings being wiped in the strange reset I just tried. But when I went into Settings>More Networks>Mobile Networks there was no longer an Access Point Names option in the menu. There is no longer a "Network Mode" option either. I used to have that set to LTE/WCDMA/GSM but now I only see a System Select option that simply lets me change my CDMA roaming mode from Automatic to Home Only.
I tried searching everywhere for the missing Access Point Names menu to no avail (and almost attempted to try flashing CyanogenMod for the time hoping this would bring back the APN settings menu) but then I realized that I could do a search in the settings app. I searched APN and the option came right up (though it's frustrating that this now appears to be hidden). Using the following settings (copied below) from the AU by KDDI website I created a new APN profile. Now mobile date appears to be working just fine too!
So, now I just need to decide if I want to keep running Touchwiz in Jellybean or use my new found confidence to try rooting and custom roms...
I'm also kind of curious to see that the next phone bill comes in as expected and I'm not being charged for a bunch of crazy usage! Also, any suggestions to help explain how I got into this problem in the first place, or how to clean up any loose ends would be appreciated.

Radio off / no network - LG-H990DS - do I have any options?

Hello,
Hoping someone may be able to help me
So this morning I lost the ability to make voice calls and use mobile data on my LG V20 (H990DS variant - totally stock). In the top right-hand corner where it shows the mobile network strength I have an empty box with an X in the top corner. Everything else on the phone is working hunky dory. Strange as the phone is stock and this didn't happen after an update, etc. Obviously it could be a hardware failure but I'd like to rule out it being a software problem as I really quite like the phone!
The phone knows a SIM card is installed as it knows the IMEI, APN settings etc. However it just won't connect to a network. I've checked the settings and the service state is set to "radio off" and the mobile network state is "disconnected" which makes sense given I can't get onto a mobile network.
Question is how do I turn the radio back on? I've tried what I think is the obvious stuff:
1) Removed the battery, left off for a couple of mins and rebooted (hoping it will then rescan and find the network) - no change
2) Factory reset - no change
Given I have the H990DS variant do I have an options? I say that as I thought this variant wasn't particular friendly in terms of flashing, ROMS, etc.
I'm a n00b but can follow instructions so if anyone has ANY advice I'd appreciate it!
Thanks muchly in advance.

Sounds like a hardware failure
Sent from my LG-H910 using XDA Labs

It could indeed be a hardware failure but I find it odd that it can read the SIM (knows the IMEI, APN settings, the number, etc) and I seem to recall when I first got the phone I had to jump through some hurdles to get the SIM to work.
Is there no way to toggle the radio on/off? I've tried *#*#4636 ... but it won't give me access to the phone information section to reset the radio here ...

did you find a fix?
