[Sprint Samsung Galaxy S 4 Original Android Develop] shadowcliffs:
I finaly figured it out! The reason I didn't got LTE is due to the system doesn't set/lock the right apn to the carrier I'm with, freedompop.

Here's the story:

After flashed 2-19 nightly, there is only 3G, plus the APN field is blank with the message in the background: Access Point Name settings are not available for this user.

Here's the step to get back to LTE:

Step 1). Make the apn list re-appear: you have to toggle the flight mode first, then a list of APN will appeare like magic. But the one for freedompop is not there yet, so

Step 2). Add apn for freedompop using the info below

<apn carrier="FreedomPop" mcc="310" mnc="120" apn="n.f6.ispsn" type="default" protocol="IPV4V6" roaming_protocol="IPV4V6" />

but somehow the phone will set itself to Boost (see reason in the link at the bottom of this post, which has been an issue since cm 11). Then I deleted the apn for Boost. Still no LTE. I looked again, this time the apn is still not fixed at freedompop. So it seems deleting one APN it's not enough. Therefore, here comes

Step 3). What about deleting all other APN except for the one for Freedompop? Bingo. Right after this, LTE is there!

BTW, I have no trouble with Stock 4.4.2 NG5 ROM where APN is automatically set to freedompop. So it's the cm that have trouble setting correct apn for mvno.

Update: found this:

Here's some issue that I found:

1. Speaker is not automatically turned off when headphones are plugged so that ring/notification sound sill come out from speaker.

2. Can't turn off the vibrate for menu and back button.
[Sprint Samsung Galaxy S 4 Original Android Develop] bobwonderful:
I've been on the last two nightly build with 2/17 and 2/18 both had issues with the APN's disappearing (I also have Ting). I have to rebooot to get them to reappear but if I select Ting and try to save it, it goes blank. I've also been only getting 3G if it's selected. I'm going to try to install 2/19 nightly build to see if anything got fixed then going to do a clean build again.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Between this and shadowcliffs comments on the previous page (kept defaulting to boost APN) it's obvious there's something going on with the APN / Mobile networking. Went back to the 2/16 nightly and was 'stuck' on LTE and couldn't make calls.

Since this is my daily driver that I need for work and have a family (and apparently currently live in a 3+ ft snow covered god forsaken tundra aka New York :laugh:) I need something more stable during the week so I've ironically rolled back to the 1/26 Unofficial. Changed the sprint MMS URL to http://mms.plspictures.com and it's working fine.

I'll check out the nightlies over the weekend(s).

I've tried both dirty and full, clean builds and neither work. The price to pay of using an econo-carrier and being on the bleeding edge. Thank the android gods for Nandroids and ROM Toolbox Pro :victory:

and even more thanks to Noobnl and the contributors to the nightlies!
[Sprint Samsung Galaxy S 4 Original Android Develop] ahl395:
Doesnt seem like anybody else is having any GPS issues.

Cant get it to work at all myself. On the latest build. GPS Test app says "No Fix" and doesnt show any satellites or anything.

Any ideas?
[Sprint Samsung Galaxy S 4 Original Android Develop] bobwonderful:
I had that originally when I went to the Nightly CM12 builds: I went back and installed the original Samsung Touchwiz ROM, activated it and made sure that the GPS worked then did a clean install of CM12.

Nothing else worked except for going back to the original Touchwiz rom.

---------- Post added at 01:23 AM ---------- Previous post was at 01:19 AM ----------

I went back to 2/13 build and that still didn't work. I'm going back to Android 4.4 (nandroid)as this is becoming very frustrating and I don't seem to get many more features with Lollipop. Then will try again later on. This is at least several days of frustration with getting LTE service. If this gets fixed.. please let me know.
[Sprint Samsung Galaxy S 4 Original Android Develop] shadowcliffs:
LET can be fixed by deleting all other APNs except for the one that is correct. For disappearing APN, try toggling airplane mode. See my previous post.

---------- Post added at 07:57 AM ---------- Previous post was at 07:52 AM ----------

I have the same feeling that I can hardly feel much of difference between stock touchwiz and cm lollipop if using the same wallpaper. The main drive for me to cm is that my phone has overheat and random wake issue with stock ROM. I don't have them with CM.
[Sprint Samsung Galaxy S 4 Original Android Develop] bobwonderful:
Well, I went back to Android 4.4 (nandroid) and it's only getting 3G. So something got borked with the APN or provisioning. I may have to go back to the original Samsung Touchwiz and updating with that and hopefully getting LTE then upgrading again.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
You probably upgraded to the NG2 modem - that's what started me on the cm12 unofficial path

Story: CM11 wasn't running well, tinkered with 12 but missed the lock screen widgets so I tried to go back to CM10 instead and my signal was all messed up. After some research, I concluded it was a NG2 modem not playing well with CM10 (now mind you, I'm a 1/2 step above a noob so my conclusion may have been completely wrong )

Now that I'm on 12, I don't want to go back to some antiquated 4.x version :laugh:
[Sprint Samsung Galaxy S 4 Original Android Develop] bobwonderful:
Reinstalled the old touchwiz backup and LTE worked immediately there. I made sure I did a network PRL update. Then tested again to see if LTE and GPS worked. Then did a nandroid again of my CM11 -20150209-Nightly-jflte and it LTE adn GPSworks. Now to see if my most recent CM12 will work.
[Sprint Samsung Galaxy S 4 Original Android Develop] bobwonderful:
CM12 - 2/19/15 nightly definitely borked when it comes to Ting's LTE. I did a clean install with CM12 2-19-15 nightly- Only get 3G. Back to Android 4.4. It also doesn't go through the set up process like in the past by using the NFC Touch with my other Samsung S4.

Does anyone know when it LTE worked well? I never had good LTE service when I installed it, even since 2/14/2014 and that was sporadic LTE service.
[Sprint Samsung Galaxy S 4 Original Android Develop] shadowcliffs:
Have you tried the work-around I posted several posts ahead for Ting/freedompop's LTE issue?
[Sprint Samsung Galaxy S 4 Original Android Develop] swiggs98:
Moving apps to sdcard finally works on 02-21.
[Sprint Samsung Galaxy S 4 Original Android Develop] d0u8l3m:
has anyone had an issue with calls hanging up? I just did a fresh install and when i press the hang up button the call just stays going until the voicemail cuts the line...i have to reboot the phone to hang up =/
[Sprint Samsung Galaxy S 4 Original Android Develop] McBadass:
I tried your fix (thanks for replying to me, by the way!) and I had no luck. The Airplane mode worked great to show the APNs (awesome find) but even after deleting everything but Ting's LTE APN (n.ispsn and n.t8.ispsn) I still only get 3G.

I even went as far as to flash stock TW, PRL and Profile update and Carrier Wipe, then re-install fresh Lollipop, and then tried to delete and re-create the correct APNs. No dice! I was so stoked to finally find an LTE fix, but sadly it didn't work.

I will say, though, that I'm on AICP Nightly which is based on CM, but not the CM nightlies. That might be it, but I have had the same problem with ALL Lollipop ROMs.
[Sprint Samsung Galaxy S 4 Original Android Develop] shadowcliffs:
You might want to take a look at the details of the apn you want to use and make sure the bearer is set as LTE.
[Sprint Samsung Galaxy S 4 Original Android Develop] McBadass:
I checked. Here are my settings.
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
My wife's phone is running the 'jflte' CM11 ROM from 2/16. Can I wipe cache/dalvik and flash the latest CM12 nightly?
[Sprint Samsung Galaxy S 4 Original Android Develop] Beezer80:
You can try. I think it will just remove incompatible apps. I had trouble eveytime i tried to "upgrade". A clean wipe is usually recommended between major versions which is what I ended up doing myself.
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
I'm going to try, making a backup to the external SD card either way.
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
Update: It worked
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Same boat as you - tried the 2/22, full wipe/clean install, deleted extraneous APN and only get 3G...it occasionally flakes out an jumps between 1x and 3G. Also appears to be Roaming but when I fire up OpenSignal it tells me I'm on 3G/2G Sprint. I was able to sms/mms and call on 2/22 so I'm going to stick with if for now.

New bug: issues with Pandora when switching apps (open Pandora, switch to my shopping list and 10 secs later, Pandora just dies. )This was on Wifi and it happened in 2/21 & 2/22. . 'Don't keep activities' or anything isn't checked but I'm guessing its too aggressive in killing background processes.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
OK - either the 2/23 build was greatly refined or I discovered the secret formula.

I dirty flashed the 2/23 nightly over my CM-12-20150126-UNOFFICIAL-jfltespr and pa_gapps-stock-5.0.1-RC2-20150125a-signed and everything works great except the blank APN issue which I don't' care since I get LTE (even in my faraday cage-esque house)

No lag, SMS/MMS work, GPS work (locks quick), calling, LTE, Wifi, Pandora all fine!!
[Sprint Samsung Galaxy S 4 Original Android Develop] shadowcliffs:
Can the vibrate of menu and back be turned off now?
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
yep, under Sounds
[Sprint Samsung Galaxy S 4 Original Android Develop] mikeprius:
What is the APN issue that is being referred to ? Is it the address that is input in for SMS ? I thought since this is carrier specific vs. unified build it comes pre-set. Just following the feedback so far. Before I used to always flash nightlies however I am so busy and need a pretty stable/reliable ROM. Seems like most of the functionality is working though.

compass issue

Hello,

I tried to calibrate the compass with GPS status, but with no success.

Compass is still spinning and doesn't point to the correct north direction.

Also GPS doesn't work!

Anyone having same as this problems?

Any help, suggestion?

I'm on cm12 build 23

Thank you,
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
APN list is empty, toggling Airplane more makes them reappear

Please review earlier in this thread (you basically have to reflash a ROM with working GPS, acquire a lock then load CM12)

Edit: this fixes the GPS. My compass seems stable now too be was spinning before. - Still not 100% accurate)
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
My wife has this ROM on her phone. She's on the 2/22 ROM. All of the sudden, text messaging stopped working today and her battery drained VERY fast without use. She barely has anything even installed on the phone, and I put a brand new OEM battery in her phone. Is this ROM not a DD? I don't follow it close enough since I don't have this phone anymore.
[Sprint Samsung Galaxy S 4 Original Android Develop] LiL_Assassin:
Apps will/are going to crash. Always check your wakelocks. That's how you find your battery drainer.
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
So the stock CM SMS app was crashing when you tried opening a text. Installed Google Messenger...Fixed that.

Battery drain... Nothing was using battery outside of 3-4%, but it was a huge dive for no reason at one point.
[Sprint Samsung Galaxy S 4 Original Android Develop] LiL_Assassin:
3-4% an hour? But yeah I use chomp sms, just clear data and see if that helps
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
No. Drilling into battery usage, usage was no higher than 3% an hour or so for the like 15 apps she has installed. The brand new battery just died in 3-4 hours for no reason.
[Sprint Samsung Galaxy S 4 Original Android Develop] McBadass:
Alright, you have me very curious now.

Let's see if I can't duplicate this. I just wiped and fresh installed 2/23. I have Ting. I did not modify my APNS at all. No 4G. I have not yet tried installing a TW ROM and then flashing back. I am just a straight flash to 5/23.

When you say you dirty flashed, on your old version what did you change with the APNs? What did you do on your previous version before the dirty flash? Did you delete all but the Ting APNs? What are your Ting APN settings?

I have hope agian!
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Nothing, I used the 1/26 APNs as is. It only has Sprint APNs.
[Sprint Samsung Galaxy S 4 Original Android Develop] matraca:
hi, I am on 2/25 and can't find the flashlight tile. is there a trick to get it or was it removed for good?
[Sprint Samsung Galaxy S 4 Original Android Develop] McBadass:
Which are the 1/26 apns? The default CM ones?
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Correct, the default CM APNs that were part of the 1/26 build.

Unrelated observation - Lost Location (gps) Quick Settings tile today, turned GPS on from regular settings and it came back.

---------- Post added at 10:20 PM ---------- Previous post was at 10:17 PM ----------

2/22 has it - I'd be surprised if it was removed intentionally. I had my gps tile disappear today then reappear once I opened it from Settings. Try opening the flashlight app and see if it reappears. Then see if you lose it on rebooting.
[Sprint Samsung Galaxy S 4 Original Android Develop] matraca:
there is no flashlight app, but like you said, all of the sudden the option to add the tile just appeared after toggling flashlight with google voice command ... weird
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Sorry - I have a 3rd party 'Flashlight app' with the same name. It has a 1x1 widget that I like.

Is there somewhere I can get the stock CM12 kernel? I am running dualboot. For the time being, after updating the rom, I have to flash a kernel. At the moment, I am flashing Alucard's 5.0 AOSP kernel. Would like to remain stock for now.
[Sprint Samsung Galaxy S 4 Original Android Develop] ACoolGuy:
The kernel is included in the nightly. from what I see. I'm currently on this kernel with no issues outside the norm.

Please insert sim card comes up when i already have my (straighttalk) sim. in.

I keep getting that when i flash the new CM12 updates and someone in another forum told me to flash an older version but i cant get the older version because when i try to download the 02/19/2015 one, i get a 404 error. can anyone help me get that working on the newer updates or can someone get me the older version of the cm12 update. thank you
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Odd - just tried and I get a 404 for anything before the 2/22 too.

I had the "Please insert sim card" before I upgraded to the NG2 modem - what baseband are you running?
[Sprint Samsung Galaxy S 4 Original Android Develop] agentfazexx:
The 404 error was widely discussed all over. The builds were not made successfully.
[Sprint Samsung Galaxy S 4 Original Android Develop] mustafa.ali61:

[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:

but research it, don't assume I'm correct. It's what fixed *my* 'insert sim' issue, it might not be the fix for you. ;)
[Sprint Samsung Galaxy S 4 Original Android Develop] mustafa.ali61:
how do i do that.
[Sprint Samsung Galaxy S 4 Original Android Develop] PwnCloud:
Couple of issues with the latest nightly so far: Automatic time zone isn't working, and data in pulldown says no service although I have a 4G connection right now. This has been occurring in previous builds as well, but I often have to toggle airplane mode or even reboot to regain a connection when I assume I'm switching towers. Happens every time going between home and work or anywhere else.
[Sprint Samsung Galaxy S 4 Original Android Develop] mulletcutter:
Same here, it will get stuck saying 3g and have to airplane mode. Its even really bad indoors.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
3rded that this was a bad build. Dirty flashed 3/3 I just got constant system closes.
[Sprint Samsung Galaxy S 4 Original Android Develop] rjm83:
Did 3/4 fix the force close and other problems?
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Seems to - loaded it last night and it's going strong, signal strong again too.

Still have an issue with disappearing quick setting 'Location' tile tho
[Sprint Samsung Galaxy S 4 Original Android Develop] d0u8l3m:
on the latest nightly and i still cant hang up calls i have to restart the phone to hang them up...anyone else experiencing this or know how to fix it ive tried pretty much everything inluding a clean flash
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Anyone know where the 3/5 and 3/6 nightlies are? It's the weekend and I'm ready to tinker!!

I realized last night that in the several months I've owned my S4 I've only made 1 phone call - a test call when I was on the CM12 'unofficials' :laugh:

I've skyped, 'hangout'ed' and other pseudo calls but no actual phone calls. It's becoming an outdated medium (for me)
[Sprint Samsung Galaxy S 4 Original Android Develop] swiggs98:
I haven't had any issues with hanging up. Would need more to go on.

I've had fun trying to get the screen to wake up after going off when I put it up to my ear occasionally.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
Getting a little flakiness / lag on the 3/8 build. Not properly reading my NFC tags like it was on 3/4.

Seems to get unstable when using bluetooth on -pairing worked OK with Pandora until I lost my 4G signal so I tried to kill Pandora and switch to VLC to listen to MP3s and the signal got static and my phone started freezing; had to reboot to resolve it.
[Sprint Samsung Galaxy S 4 Original Android Develop] PwnCloud:
I can't get data when I go into town now. Flashing an older ROM didn't solve the issue either. Normally I get 3g there, but it's just no service at all. At home it's fine, I have LTE, but it ducks because I can't tell if anything I do at home will work until the next day.

If anyone knows what I can do to fix this I'd really appreciate it.
[Sprint Samsung Galaxy S 4 Original Android Develop] mulletcutter:
New build got green tint, changing brightness did change it.
[Sprint Samsung Galaxy S 4 Original Android Develop] ACoolGuy:
Its the dang new live display settings

Try this. Go into the color calibration in settings and change the values to about 50 on red/green/blue. then go out and change the brightness manually. Strange but it seemed to help in my case. also if you getting too much green, make green lower until it looks right to you.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
nice! I'm on 3/11 and it had the greenish tint. Your suggestions seemed to almost fix it but was slightly blue so I have to keep tinkering.

For me, @ 100% brightness, everything looked good, it was only tinted green (and now slightly blue) when I'm less than 100% bright.

edit: make sure you adjust your brightness to 100 then to something else (50?) after changing the color, it doesn't seem to apply right away.

For me R(100), G(90), B(100) looks fine

Edit2 - the tint changes; at 100% brightness the green is back, lower and it seems OK :|
[Sprint Samsung Galaxy S 4 Original Android Develop] rjm83:
Does the 3/12 build fix the color issue?
[Sprint Samsung Galaxy S 4 Original Android Develop] Beezer80:
It's better but it didn't for me.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
I had to rollback to 3/8. I finally got my screen color ok but 3/11 made my dash cam vids all blue tinted and made the phone get hot as hell.

I'll try the upcoming weekend's builds.
[Sprint Samsung Galaxy S 4 Original Android Develop] PwnCloud:
No audio in the past couple nightlies. I missed my alarm this morning and got to work late.

[Sprint Samsung Galaxy S 4 Original Android Develop] PwnCloud:
Sorry, I found this issue isn't just on this ROM, it's persistent across literally any ROM I flash, so I'm not sure what to do.

I tried today's but the colors are borked still for me.
[Sprint Samsung Galaxy S 4 Original Android Develop] KFloyd:
3/13 is working well - still was slightly green, adjusting color calibration (green @ 92) fixed it, my dash cam app is fine and adjusting the brightness doesn't make the color all funky either.

Used 3/13 for about the past 24 hours, heavy dash cam use and no overheating or weird colors. Did have a couple of freezes (or 15 second lags) but it's pretty solid again.
[Sprint Samsung Galaxy S 4 Original Android Develop] d0u8l3m:
I still also have the green tint

Still cant hang up calls...so the main function of a phone is broken.

And now for some resaon it seems after the phone is sitting for an hour or so the mic will stop working and i have to restart the phone, if not noone can hear me when i make calls with any app

2 Bluetooth Devices Issue

Using all the CM12 nightlies I have had issues with my Blackberry BT media gateway device.

I use it in my car because my car only supports phone calls, not stereo music or audiobooks (A2DP).

The nightlies will often work once or twice right after being flashed but then only the car phone BT connections will work.

The phone detects and (at least thinks it's) paired with blackberry media gateway, but when I play audio it doesn't actually go through the device into my AUX jack.

I can get audio to come out of the phone speakers by powering down the blackberry, and then I can get it to stop playing again by powering up the blackberry device.

---------- Post added at 09:02 AM ---------- Previous post was at 08:58 AM ----------

I find that my alarm settings often get reset, or if the alarm times are still there, the audio files they reference no longer exist so the alarms are silent.

I often have to go in and set the alarm sounds manually.
