I recently got Samsung GS2 to use on ATT in the US. Overall the phone works very well, however I keep getting "no service" at seemingly random times in known good cell reception sites (like my house). The phone appears to be working fine with 3-4 bars and then all of sudden the signal drops and I loose all connectivity for anywhere from 10 seconds to 3 minutes (wifi appears unaffected).
Here's what I've tried so far:
-Running stock KE7
-Downgrading my baseband to NEKD5
-Selecting "GSM only" in my network settings
-Disabling fast dormancy
-Running Lite'ning ROM just for kicks
None of these make the problem go away.
Please lmk if there's anything else I should try. Thanks in advance!
I am having the same issue on Vodaphone in the uk. Seems the only way i can avoid it is to hold the phone with finger tips top and bottom and not grip around the back! This also seems to improve wifi signal.

My problem doesn't seem to be related to how I hold the phone. I've tried holding it several different way, plus just keeping it laying flat on a table and it doesn't seem to make a difference...
I have a similar issue:
whenever I loose my 3G connection and there is no roaming GSM available the display show a "stop icon" in the upper display. That's ok... The problem is that when I put it where I know for sure there's the signal it won't reconnect but seems to stay disconnected (no service) forever! I have to force a Airplain Mode ON/OFF to make it search and catch again the signal in a few seconds. Never rooted the phone, official KG5.
My settings: WCDMA + GSM, packet data on (when in 3G, no roaming data allowed). H3G Italy.
I know at least 3 people who reported the same problem in Italy with different carriers.
Whenever it looses WCDMA + GSM, it hardly reconnects to the newtork leaving the phone in "No service", totally offline from calls too....
Finally fixed starting from fw KI4+!!
I am on a rooted i777 and have been having signal issues pretty much for the two months I've had this phone. I've done some searching to see what the problem may be but have not come across much.
What happens is that when I have a strong cell signal I am able to send messages and make calls but about 60% of the time when I try to load a web page, update an app's content, or open the market (access the internet in general) I am unable to and left with an "unable to connect" message. During these times only the outgoing arrow of the two beneath the H+ is active. In such situations I switch to wifi but I would rather not have to, especially with an unlimited data plan. So my question is why is this happening and what can I do to fix it. I've nearly thrown the POS over this. It is very odd to say the least. It should be noted that I replaced my AT&T sim card a few weeks ago to no avail. Thank you
I've had similar issues. At various times throughout the day, my phone will be completely without signal or with signal but unable to get any data. I also changed the SIM card to no avail. I don't believe it's the phone but either AT&T or the settings.
Is it possible your reception is dropping off at these times? Does your phone switch to EDGE or GPRS?
Try changing your APN with one of the apps in the market. That tripled my speeds and once I get a new APN to stick, I suspect it will fix the loss of a data connection.
If that doesn't work, return it to bone stock and do a warranty exchange.

I had no data connection tonight and almost nothing worked. In the end, I turned Airplane Mode on and off. That returned my data connection.
I think once it loses signal, it only checks every x minutes. Mine would go a while with no signal, but pick it up immediately if I toggled airplane mode, as you found.
Hey guys, first off, I have searched for no less than 2 hours for an answer to this question, and while there are lots of discussions, none of them seem to replicate what I am seeing.
Can anyone confirm this, and does anyone have a fix?
GPS will not lock a single satelite in Airplane Mode. I'm in American Samoa without cell coverage, and using the GPS Status app to test. Here's my findings:
First, I turn off Airplane mode, turn on WiFi (connected), turn on GPS. I do not get a cell signal. I open GPS Status, GPS locks onto the first satelite within a minute, and locks position in 10 seconds after that. I turn Airplane mode on which turns WiFi off. Interestingly enough, GPS is not turned off. I turn GP Soff, and then turn it back on (have read suggestions to do so, and have also tried not switching it at all). I then turn Wifi on and verify connection. I open GPS Status, and let it sit for up to an hour outdoors, not a single satelite ever appears. I turn Airplane mode off, and within a minute I have a locked location.
So, two questions, is it possible to get GPS to work when in Airplane mode, or is it possible to disable the cell radio some other way (possibly keeping GPS enabled)?
Here's my stats:
Phone: Moto Razr Maxx
Rooted: Yup
Carrier: Verizon
Sys Version: 6.12.181.XT912.Verizon.en.US
Android Version: 2.3.6
Baseband: CMDA_N_04.07.01R LTEDC_U_07.1F.00
Purchased about a month ago
Playing around a bit more, I noticed that when I have airplane mode off, and GPS on, and GPS Status open, if I quickly hit the home button, turn Airplane mode on, and go back into GPS Status, a lock remains for about 3-5 seconds, and then satelites slowly start disappearing until there's none left. Airplane mode is definitely disabling GPS on my phone.
Anyone? Bueller.... Bueller... Bueller...
I can post video if you don't believe me...
I have read that the GPS needs a data connection to make a lock. I don't remember where I read that, but I had the same problem when I was in Europe trying to use my phone primarily as a GPS device with cached maps. There was maybe once or twice that it actually locked, out of many many many many attempts.
I have airplane mode on, wifi and blutooth off, then turn on gps, I get gps lock on my Droid Razr with stock gingerbread for a short period then lose all satellites. It appears that you can't use gps with airplane mode on.
bump i have been wondering about this also. airlines often expressly allow gps. after all, gps RECEIVES, it doesn't transmit.

Actually GPS doesn't need data connection to make a lock. But with data connection it helps make lock much faster.. that's the features called A-GPS (Assisted-GPS), google around about A-GPS for more detailed info how it works.
I always turn off my data connection every time i use my razr for navigation. I only turn data connection sometimes to make the GPS locked and after i got a lock i always turn off the data connection (I'm not on data plan) and even i didn't turn on my data connection I still can get a lock as long as i am outdoor. So far i never had razr GPS lock problems. This phone's GPS never disappoint me.
My guess is maybe it's some kinda bug on the airplane mode or maybe that's intentionally for some safety reasons.
Same here. I did:
- open maps, locate my position. ok.
- turn off wifi and data
- go back to maps, position ok.
- longpress power, turrn on airplane
- gps starts blinking, position lost
- turn off airplane, but data remains off
- gps position found in 2 seconds
(also tried with "GPS Test" app - same result)
I have MAXX AsiaRetail stock 2.3.6

Thanks guys, nice to know it's not just me! Just to clarify some other posts, GPS works with or without a data connection as long as airplane mode is off.
So, seeing as though airplane mode kills GPS, does anyone know of a way to disable the cell radio (to save battery life) without turning on airplane mode?
And just to comfort those who worry about flying, I'm just using the phone for directions and what not (American Samoa doesn't have street addresses believe it or not, and 2 houses past the third palm tree doesn't cut it ). I download the directions while at the hotel on wifi, then go about my way, but if I can't use GPS in airplane mode, it kills the battery searching for a cell tower.

Couldn't agree more, while in the states with cell reception, this phone's GPS is fantastic! Unfortunately, if you have to keep airplane mode off to have it work, it's useless in the back country, or 3rd world countries. Maybe today's ICS release will fix the bug!
I don't think it's a bug. My droid X did the same thing.

Moved To Q&A
Please Post questions in the Q&A section
On my Razr Maxx I also have no gps in airplane mode. I'm running the official 4.04.
I'm going to guess this is because the droid radio chip has gps integrated along with the cellular radios. Here's my evidence:
Turning off the radio with the LTE OnOff app (it just opens the radio service menu, same as dialing the service number), and pressing "Turn radio off": Gps Test would never see any satellites and would never get a gps lock.
Setting the "preferred network type" to "GSM only" (this has no service in Seattle with Verizon): Gps Test immediately sees satellites and I get a gps lock.
I wish there was an option to turn off all the cellular radios but to leave the gps radio on. I use my razr maxx hiking with offline topo maps and OruxMaps, and it lasts about 8 hours recording tracks every 1 minute.
Possible solution?
My findings are that when using my Razr Maxx still on 2.3.6 stock settings, If I run the GPS Test application with GPS, 3G data and cellular on (airplane mode off) it acquires my location accurate of 10 feet, using 8-12 satellites in approximately 10 or so seconds. If I exit, toggle Airplane mode on, relaunch GPS Test, it will acquire my location in the same time, accuracy and with again 8-12 satellites. But If I exit, toggle GPS off and then Airplane mode on, Toggle GPS on, relaunch GPS Test, it will not be able to locate any satellites.
Now, with that said, if I go into my data/data/com.android.providers.settings/databases/ directory and open the settings.db file, in the "system" entry, I do not have gps listed in either the "airplane_mode_radios" or the "airplane_mode_toggleable_radios" values. I do have "cell,bluetooth,wifi" under the airplane_mode_radios value, and "bluetooth,wifi" under the airplane_mode_toggleable_radios value.
I do not know how this looks in ICS for the Razr (4.0.4). I also do not know if gps is even able to be included here. Just a theory.
I might be on to something that may work and you will need to be rooted.
I warn you, that I have not tried modifying this myself, so I cannot verify it will work. Do not try this if you aren't comfortable with attempting it without it being verified to work first.
What I'm thinking is to use an app like Root Explorer and navigate into the data/data/com.android.providers.settings/databases/ directory. Open and edit the settings.db file with an app like SQLite editor. Then open the "system" database entry. Check to see if on around lines 21 and 22 there are entries named "airplane_mode_radios" and "airplane_mode_toggleable_radios". Once located, check to see if their values include gps among the other available radios. If the airplane_mode_radios value includes gps, then long press, tap edit field, remove it and save. If gps is not listed under the airplane_mode_toggleable_radios then long press, edit field, add gps and save. Exit and reboot.
I think with doing this, it should not turn GPS off when airplane mode is toggled on and it should allow you to toggle GPS on and off while airplane mode is on.
If anyone else knows of an easier or proven way to do this then let us know.
If you know this will not work, correct me and let me know.

I'd like to confirm that I'm having the same issue of having no GPS connectivity when in airplane mode even though the GPS has been toggled on. Numerous other forums have stated that this is a hardware issue with Motorola phones. I'm curious if the above quoted solution has worked for anybody.
Thank you!
This is the response that I got from Motorola after asking the general question about having GPS turned on when airplane mode is on:
"When airplane mode is enabled, this will automatically disable all wireless and radio communication on the device including the GPS receiver. Because the phone, in order to determine location, takes readings from both GPS satellites and nearby cellular base stations (towers), with the help of a location server on the network. In other words, the phone relies on the network for help in determining location. Although the phone does receive GPS signals directly from the satellites, it can't determine actual location without help from the cell network."
Therefore, you can't use the GPS radio by itself.

But the GPS still works fine when I am far away from any cell towers of any kind...
I think whoever responded to you was trying to justify airplane mode turning off GPS. There must be a way to force it to stay on.
It has certainly frustrated me that I can't use airplane mode to save battery while using GPS.
I'm by no means an expert on this issue but I think the GPS and cellular radios are physically connected (on the same chip??) inside most Motorola phones. So even though you might not be near a cellular tower, and if airplane mode if off, you should be able to get a GPS signal. But if airplane mode is on, then both the cellular and GPS radios will be turned off.
Basically, the interwebs is pointing to a hardware issue rather then an a software issue. However, I hope a software solution is available.

I'd give $20 for a software solution to this problem. I am an avid hiker. Using a cell phone in Airplane Mode you get 4x, 5x, 6x the battery life. If I can use GPS while in Airplane Mode, I can hike a very long time, but if I'm forced to leave the cell radio on merely to use GPS, the battery won't last a full day's hike. It is ridiculous that we can't (yet) use GPS in Airplane Mode. I have been using ViewRanger offline navigation app for years. I download to the phone before I leave home all of the topo maps that I need for a hike, so I have no need for data when I'm hiking.
Did anyone ever try editing the systems.db file in data/data/com.android.providers.settings/databases/ directory? I can't tell that the guy that wrote that post ever tried it himself.
EDIT: I found here documentation of these two settings.
AIRPLANE_MODE_RADIOS -- A comma separated list of radios that need to be disabled when airplane mode is on.
AIRPLANE_MODE_TOGGLEABLE_RADIOS -- A comma separated list of radios that should to be disabled when airplane mode is on, but can be manually reenabled by the user.

My XT912 is rooted and I have System set to read-write. I tried to use SQLite to edit the value of AIRPLANE_MODE_TOGGLEABLE_RADIOS in the System table of /data/data/com.android.providers.settings/databases/System.db to change it from "bluetooth,wifi,nfc" to "bluetooth,wifi,nfc,gps" but even though I have write permissions to the file, when I tried, I received this error:
Update Failed - Error Code 5. Database is locked.

I went searching for how to edit settings.db and found this thread and this other thread, but I don't fully understand the instructions.
Bottom Line: if this is truly a hardware problem, then editing this file won't fix the problem (but likely won't cause any harm either), but if this is merely a software problem, then this may finally give us GPS use while in Airplane Mode.
I updated to N900VVRUBMJE last night and woke up this morning to a SIM NOT INSTALLED (or similar message, I didn't save it). I fixed it by simply rebooting. I'll keep an eye out to see if it happens again. I've never had that happen on this phone (I've had the note 3 since the day it was released).
MJE wifi connectivity problems "staying connected"
I feel ya. I'm having problems with my home wifi. Works fine as long as i have at least 1 bar of service. I live about 1/2 mile from a cell tower but i think my home is in a dead spot because i can only manage to get 1 bar, if i go into my bedroom i loose signal all together but have full wifi bars but even with full wifi service in my room it still constantly drops wifi, i can only seem to manage to stay connected as long as i have 1 bar of service. I have already went into wifi settings and made sure the wifi auto switch was unchecked. I also opened root explorer went to efs, carrier opened hidden menu with texted editor turned the ON switch to OFF. Still no luck. So i changed it back after about a day. Im starting to wish i would had gotten the HTC Max.

Changing the Hidden Menu text from off to on only gives you access to the hidden menu...it does not do anything to change wifi or any other settings. Once you've set the hidden menu from off to on, you then have to go into the hidden menu by dialing *#27663368378# and then at the ServiceMode screen, press the hard menu button, then select Wifi, then press the button under WIFI POWER SAVE MODE to turn it off.

I did notice a decrease in LTE signal strength after updating to MJE and I have since flashed back the MJ7 modem and everything is back to normal.

I also noticed a tremendous decrease in LTE strength, but flashing the MJ7 modem didn't fix it for me unfortunately. I'm going to install SS, root, and flash CleanROM to see if it gets fixed somehow.
Overall, can those of you have that already installed the JE update provide any input as to how has the performance of the update has affected the performance of the phone?
I'm running Beans B4 right now, and would like to update to B5, but have to take the JE update in order for the ROM to work.
Any further feedback would be appreciated. :highfive:

I didn't notice any change in performance...either positive or negative. My initial OTA update did break video recording for some reason and it just didn't 'feel' right. So, I did an "emergency firmware recovery" via Kies and everything worked great after that, so I guess something just went wrong with the original OTA update. I didn't have any volume/sound issues to begin with, so I don't see any major difference...but I've seen lots of reports that people who were having issues are pleased with the results.
I did however notice that my LTE signal strength was terrible. I went to our local mall, where I usually have one or two bars, but can always make and receive calls. I kept getting 'no signal' & '1x' indicators. I got home and my wife said she called me six times...I didn't get a single one. I checked my signal strength while sitting in my bed & it was 106dBm. I then flashed the MJ7 modem that night & afterwards my signal was at 97dBm sitting it the same spot. The next day I went back to the mall and called my wife with no problem. I had her call me at five minute intervals as I moved throughout the mall and I received every call. That might not be scientific results...but I won't go back to the MJE modem. The good news is that you can update to MJE and still use the MJ7 modem like I did.
Hope that helps!
My experiences have been positive so far. My LTE Speeds have increased quite a bit. The only thing I've noticed....one of my Apps, Camera2, will NOT open, it simply crashes,
I have a bizarre problem that just started happening, I can't connect to mobile network after using a wifi connection for some time. No matter what I do, the S6 edge won't connect.
I've tried switching mobile connection on and off, restarting the phone, turning the phone off and back on, switching sim cards with another phone (the other phone immediately gets connection), switching airplane mode on/off. I've gone to Samsung and my mobile provider and they have both blamed each other (of course, right?). The most frustrating part is that this happens about 50-75% of the time with my home and office wifi, and almost never with anyone else's wifi (for example trying it in the Samsung store). It will sometimes get a connection 10-15 minutes later, sometimes it takes several hours.
Samsung service has offered to take the phone in to 'review and test' but they need to do a full wipe and it will most likely take several days of testing. Knowing that the problem is almost impossible to replicate outside of my home and office, and the issue goes away by the time a service tech will ever see the phone, and the struggle to back up and restore my apps without root, I'm not sure what to do right now. Temporarily I have turned off wifi and just use mobile connection, but I'll hit my monthly data cap really soon.
This started happening 2 weeks after AOE4, just upgraded to AOE8 and it still happens. My phone is SM-G9250 with Taiwan ROM.
Screenshots attached to show I have good signal strength but not data connection, and the SIM in another phone having a connection (Zenfone 5 with lollipop).

Did you try wiping the cache?
I thought the cache is wiped whenever you do OTA update?
I'll do it manually again right now and see if it helps. Thanks for the tip.

I have the same issue! Very annoying, and miss phone calls all the time or am unable to make them because of this...
Will try the cache wipe
Wiped the system cache from Boot, problem still there.
I also wiped the cache for all apps.
I also tried the phone in safe mode and has the same problem.

So the only work around I can find is to go into settings:
1.) 'Mobile Networks'
2.) 'Network mode'
3.) Switch to 3g/2g (I don't have 4G right now, have to pay extra for it)
4.) go to 'Network operators'
5.) 'Search Networks'
6.) choose my network provider
Now the phone works just like it always did, smoothly switch between wifi and 3G and H/H+
I'm not sure what changed as I have never had 4G since it costs me extra.
