I have a Samsung Galaxy S2 running the Omnirom 4.4.2-20140406-i9100 Nightly.
The issue is that every now and again I can't make calls or recieve calls (I'm basically listed as unavailable for anybody that tries to call me). Even when this happens, signal bar remains full and the phones status page lists the phone as in service and connected to the network. The only way I can fix it is by restarting the phone. Are there any fixes?
- Update the nightly to confirm if your phone has no hardware issues.
- Go back to stock to get the stability in mobile network connection.
Most probably the nightly might have a broken component as these builds are experimental and highly unstable, but no harm in reverting back to stock to ensure your phone's safety.
Thanks, flashed the latest nightly last night. Now I'm waiting to see if it happens again. If it does I might consider flashing a modem that might work better with my carrier. Are there any TWRP flashable modems out there?
Started doing it again this morning, so I changed Network type from 2G/3G Preffered to 3G Only and it started working right away. Still unsure what the cause is though.

The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
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.
I bought a Samsung Galaxy S III while on vacation. I didn't really want a US model, since I already had a Galaxy S II and the only compelling reason I would upgrade was for the quad core Exynos.
Well here I am back States-side, and it's been working fine for a week or two. Last night I suddenly lost the ability to connect to WiFi networks.
Basically I can search for a connection, it will show up and say it's "Saved," but it will not connect, even if I manually choose the option. If I choose "Forget" and reconnect, it will connect briefly for a few seconds and promptly disconnect again.
I've tried the usual steps of rebooting, checking my network, etc. I've gone as far as reflashing the firmware which doesn't seem to fix my issue.
I have several other devices and none of those have issues connecting to my wireless network. I've tried a couple different AP products, including an Apple Airport Extreme, a Linksys WRT-600N, and a bunch of really old APs with a different chipset manufacturers, none which seem to work.
For OS, it's currently on Android 4.0.4 with the stock Samsung TouchWiz interface, no carrier customization.
Since returning/warranty for this device is out of the question, I am looking for a possible solution to my issue. I am not a big Android user. I used to be big on Symbian, and now I'm mainly an iPhone user. I have an Android phone to keep up with the times, so to speak. Is it possible I'm missing something? Could I have changed a setting that would cause my wireless issues?
Thanks!
(Tried searching this topic, didn't turn anything up)
I'm having the same problem too. Everything connects except for the S3. If I reboot the router it works for a day or so then the problem re occurs.
If you get disconnected meaning there's interference in the frequency range, you could change the channel so it doesn't overlap with your neighbors' or your other APs, remember any AP operating on the same channel or nearby channels in range is likely to cause signal to interfere with another AP's wifi signal.

I had similar problem. A factory reset fixed it.

I tried another factory reset and I'm still experiencing this issue. I'm a bit bummed out at the moment. I can't connect to other networks either. At least I have cellular data to work with for the time being, but I expect I'll get throttled sooner or later.

I don't think it's an interference issue.
Like I said, none of the other devices have connectivity issues. I haven't really changed my wireless setup for the last 10 years. Always the same channels (with difference channels for each overlapping AP—channels 1, 6, and 11). My cordless phones all use DECT which runs on 1.9GHz and I usually have Bluetooth off when at home. As for neighbors, the distance between our homes are far enough I am never really in range of their networks.
If enabled, turn off power saving
same problem as yours. i've replaced the kernel and still testing.
I have this problem, i think it's hardware problem, just updated the f/w hasn't made it better.
Try adding your wifi manually and select correct security protocol....it resolved an issue like this on my iphone4s.

it doesn't work for the SGS3, it's a known problem, i've checked a few sgs3 and some have this problem including mine, i'm changing my unit tmr.
Has there been any temp fix for this? I've been noticing this a lot more when using WhatsApp, usually you can see the last time your contact has been on, but it only shows if there is a current connection to the internet. When I'm connected to the wireless, it'll show up but after a while, I assume the wireless loses connectivity (sort of) and it won't show the last time they were on. The thing is though, I'm able to get to any pages like normal, so it doesn't actually lose connection.
Why don't you flash a better rom~~
S3 wlan bug
Paranoid Android wlan bug
Hello all together
I need flash PA v2.1 on my SGS 3 !
I have problems with the Galaxy S3 and WLAN simply gets no connection together!
I've already tried all possible steps like Stockrom flash with Odin to the bootloader from the Android 4.0.4 to get! Because it means that even if wifi is broken, you should flash back to flash and then stockrom Paranoid! Wifi can not connect!
I count times on what I've already done everything without success:
ICS 4.0.4 STOCK
wipe data
wipe chache
wipe Dalvik
Permission fix
Flash paranoidandroid
flash gapps jb
flash hw compressor
Wlan ist broken
Then I created a backup of it.
Have again flashed back to stock 4.0.4 ics because I had suspected at the bootloader.
Ics 4.0.4 on it again as everything was wiped and the backup recorded. Again the bow
Then cm 9 installed as described
there is also the wlan bug
from CM9 paranoidandroid
still wifi bug
then back to stock and on CM10
end result
wlan goes
paranoid then flashed wireless bug
then of stock on CM9 on from there and CM10 on paranoidandroid wlanbug
from CM10 by backup still wifi bug.
I just do not know how to fixxen it.
Would appreciate your help very

Hi all!
For about a week my International Samsung Galaxy S3 (i9300) have been experiencing network issues. At first I have full connection and after a while the network cuts off and my sim card disables (in the status bar the mobile data icon shows "no data sim") and then it switches back on and everything works.
This process happens constantly.
I have tried numerous solutions like flashing new ROM and trying to view logs.
It still shows the IMEI and I don't want to unnecessarily modify my EFS I've read that it can cause serious problems.
What is the problem and how can it be solved? Any help is most welcome and I will send logs and info if needed.
If the problem is already solved please show a link because I couldn't find anything that helps.
Thanks in advance!
I'm having a similar problem with my I9300 as well, the difference is that the network only gets cut off when I try to make a call, and then it comes back after a few seconds, and it doesn't show 'no data sim' it just stays with no connection (no bars). Messaging and 3G Data connection works fine.
I already tried to solve with several methods, the only one that I didn't try is to Odin flash back to stock, wich I don't really want to. I'm running cm-11-2016 at the moment.
I recently left the stock rom to install custom firmware on my Galaxy S5 (SM-G900T). I am noticing some strange behavior with LTE, and was wondering if anyone else was experiencing a similar issue. With LineageOS 14.1 (klte) currently, upon rebooting the device, it remains on HSPA+ for at least 10 minutes or so before connecting to LTE. If the device is kept running, and is not turned off or rebooted LTE will persist just fine, even if I change the radio selector to 3G or 2G, it will always go back to functioning LTE. On the Stock rom, I never experienced this issue. I previously ran Android 6.0.1, before upgrading to LineageOS. I have also tried with Cyanogenmod 13 to compare, and experienced the exact behavior. I have tried using the dialer menu on LineageOS (*#*#4636#*#*) to see if changing the radio settings makes any difference, sometimes it will make the device connect to LTE faster, after a reboot. If anyone has any insight on how to correct this that would be great. Thanks.
Which firmware version are you on?

My current firmware is G900TUVU1GPE1. I am also currently running cyanogenmod 13. I flashed back to stock today to take a look at some settings in the service menu. I tried setting LTE Band preference to 17, and it made no difference upon returning to cm 13.
My current "workaround" in cyanogenmod, after a reboot or poweroff, is to go to the dialer menu (*#*#4636#*#*), change radio to LTE/GSM/CDMA, turn off the radio, select LTE/GSM, turn on the radio, then immediately reboot. After a reboot, I can go to Cellular network settings, toggle 3G, then toggle LTE as preferred. I now have LTE, until the next reboot or poweroff.
I'm wondering if there is something in the stock service mode that has to be set, that cyanogenmod somehow does not have access to?
Thanks
I don't recall anyone else with the same issue. I'd try the latest modem, GPK3.

I just tried out the latest modem (GPK3), and I am still experiencing the same problem unfortunately. I don't believe I mentioned this earlier, but the device is unlocked and I am currently using an AT&T SIM. However, I have had no issue with the LTE persisting on reboot with the stock rom though. I'm curious if an alternate rom might be beneficial, perhaps resurrection remix. Have you ever tried your device with an AT&T SIM? Thanks again.
Partially solved. I discovered now that if I toggle 3G under Cellular Networks before rebooting or turning off the device, I am able to select LTE after a reboot or power off and connect instantly. Perhaps this is somehow related to using an AT&T SIM. This is a little better than before, at least.
I had this issue on CM13, since the CM forums are now gone, it's hard to find the old threads troubleshooting these problems. Here is my solution:
Yes!
Thank you for posting this, my last post was 3 months ago on this issue and I was documenting everything I troubleshooted and getting 0 responses..
There must be something glitched with the APNs on this phone, by default I was only seeing Straight Talk with GID set as the MVNO type, after disabling this I could see more APNs and add more, but could not discard them.
/system/etc/apns_conf.xml - Delete this (you can backup just incase)
Go back to APN Settings and Reset to default, then add your APN.
Once I saw HSPA+ I restarted my phone and got LTE and the radio seems less laggy now, only have been testing for a few minutes now.
Only issue is I restarted with LTE and LTE wouldn't come back, I toggled airplane mode and immediately got LTE (unlike before where the radio would take forever just to get HSPA+)

You can use archive.org to view the old Cyanogenmod forums, the buttons don't usually work, so you will need to open them in new tabs.
https://web-beta.archive.org/web/20...org/topic/120995-cm13-lte-doesnt-work/?page=6
Also, if you have problems deleting that file (or simply renaming) try:
Try to use one of the following ways:
mount -o rw,remount -t rootfs /system
or
mount -o rw,remount -t rootfs rootfs /system
You also can use it for any folder that you need even root (/)

I'm having the exact problem you're having. But it's not just my S5 on LOS 14.1, it's also my roommate with S4 on LOS14.1 and other roommate with S3 on CM13. We're all on Ting, we all started having the same problems at the same time, exactly like you describe.
I called Ting and they told me the towers were being "modernized", and that NONE of these phones had the optimal frequencies to use their new LTE. I got a long email from them about frequency compatibility but my initial research leaves me skeptical. All these phones have the frequencies tmobile says it uses, according to wikipedia.
So, they're sending us new sim cards, which I bet is just another BS fix, just like the 100 times they had me reset my APN settings and pull my battery : p
I installed the latest LineageOS on my S5. I am now seeing network issues. I get drops after calls, and wifi enable/disable. I see a "x" on the bars in the status menu.
If I cycle data on off it seems to reconnect - on but not on full LTE .
After a google search I found what could be the cause, the Verizion radio variant was added to the KLTE builds. You can see it on that forum at reddit.com/r/LineageOS/comments/605y43/please_dont_add_verizon_variant_into_klte/
I didn't actually try the "fix" they offer there because I don't quite understand it.
I gave it a shot and installed the force_g900f_ril_blobs.zip using TWRP and can report SUCCESS. Its a fix of sorts if you are on T-Mobile using another variant like me, in this case a G900V (S5 Verizon).
Hello guys, I'm having a huge issue with my mobile network.
For the past two weeks I've not been able to make use of my mobile network correctly, it sometimes works, but most of the time doesn't. The icon in my status bar shows there is activity, it's fully connected to 3G or LTE, even with full bars. But all my apps like Telegram, Pokémon go, Messenger and the likes are stuck "reconnecting" to the network, as if my phone doesn't have any reception at all. At some points even SMS messages refuse to send, even though I've got full reception.
I've already gotten my SIM card switched out, attempted multiple clean flashes and the issue still persists.
Phone: Oneplus One
My current firmware: 0.1.c1.11-00006-M8974AAAAANAZM-1
Current ROM: idprophecy's unofficial optimized lineage-14.1-20180413-UNOFFICIAL-bacon
Current Recovery: Kutep0v TWRP 3.2.1-K2
Is there anything I can do? I'm getting really desperate.
This is my last plead on this forum, as I haven't had any response from anyone since april 25th, I've got nothing else to do but wait. Can't find anything on the internet about this issue, you're my last hope.
Have you tried flashing to stock version?
