After installing muzzys 4.2.2 ROM while on LTE I can turn on the WiFi and then go settings/about phone/status and then watch the data toggle back and fourth between LTE and CDMA 1x. After a few minutes its stops and stays on LTE. Flip WiFi off and then its normal again. This is my only issue with ROM.
Edit here is the catlog the last 1/2 hour is when I switched on the wifi and noticed the problem.

I just got one huge issue about my GN when i change my Mobile ISP.
Every time when i enable data with HSPA after 3-10 seconds GN will lose signal Suddenly,
But if i enable "use 2G networks" then everything goes fine.
I try to put the new SIM card to my friend HTC Desire HD no issue at all.
And i try both 4.1.1 and 4.0.4 Rom and some baseband nothing changed still will lose signal when i enable data with HSPA.
I am on straight talk and a few months ago my phone started automatically trying to switch preferred network mode from GSM/WCDMA (auto or preferred) to LTE/GSM/WCDMA every five minutes on the dot. I assume this is because straight talk now uses the LTE network as well. When my WIFI is off, the phone connects to LTE within a second or two and stops switching the preferred network. At that point, everything is fine, and the phone does what it's supposed to, seamlessly switching between LTE, HSPA+ and 3G depending on what signal is strongest.
Here's where it gets weird. If my wifi is on, then I cannot choose LTE/GSM/WCDMA as my preferred network. The phone however keeps automatically trying to switch to it every five minutes. It switches up from GSM/WCDMA preferred or auto (which are the only two i can manually choose) to LTE/GSM/WCDMA, at which point the phone doesn't get ANY signal, including cellular reception (I know because I've tried calling myself from another phone and it goes straight to voicemail). It stays there for about 30 seconds with no reception before finally giving up and reverting back to GSM/WCDMA. The signal comes back and everything is fine for five minutes, and then it automatically tries to switch up again and i lose service again for another 30 seconds. When I restart my phone, the preferred network always starts out on GSM/WCDMA auto and then starts automatically trying to switch up. It's just that if i have wifi turned off, it connects to LTE and everything's fine and if i have wifi on it does the whole cycle i described no matter what.
The only strange workaround that I've found is that if i wait for it to cycle twice while on wifi, losing reception and then reverting to 'GSM/WCDMA auto' and getting it back, i can then toggle the LTE button in the power menu twice and it stops trying to change preferred network. That only works until the next reboot, and of course means i never have LTE. It's very strange. I've tried different ROMS and different modems and it's always the same except that sometimes a different modem will change the interval between the preferred network automatically trying to change. Also it happens when the wifi is turned on, whether or not i'm actually connected to a wifi signal.
Sorry for the essay, just wanted to be thorough, as i've been searching for a long time and find many similar threads, but nothing quite describing my problem. Any help would be greatly appreciated.
Model: SAMSUNG SGH-1747

Android version: 4.2.2

So I have been having reception issues with my sprint s3. Stock rooted 4.3 rom with kt kernel.
About the time of the 4.3 update I noticed that the reception while in lte/cdma is only 2-3 bars when it used to be full. I use airave at home. Recently, I started noticing that in lte/cdma mode, the phone constantly has no reception, that is, every 30 seconds to a minute the signal is gone and then reappears. At the same time, I noticed that the airplane toggle lights up for a few seconds. Switch to cdma only resolves all issues, even the signal is full strength. At the same time I constantly see preparing network notification and sometimes phone reboots automatically. At times I can't even switch network from lte/cdma to cdma only. I have to repeat the process multiple times. Reinstalling Mk3 modem doesntt help. Installing MD4 model doesn't help either. Updating PRL and profile does nothing.
I don't have any battery saving apps or settings enabled for this to happen. Is there any stock apps or files that can have something to do with that? Like the apps on the systems folder?
I appreciate all the help.
Thanks.
So, yesterday I flashed my phone from lollipop to kitkat after a version for my phone was finally released due to a member of this community(thank you <3) and everything went smoothly and I had no hiccups during the process... but once I restarted my phone, I noticed I didn't have 1x, 3g, or 4g as a signal indicator but I had full service and I could make calls.... just no texts or data.
Any idea how to fix this? I should note I'm using nTelos.... and it's CDMA.
I can sometimes get it to connect to 3g using an APN edit in the hidden settings but after like 5 minutes it goes back to full bars and no data connectivity.
First off love the ROM but can't post in the Dev area yet...
I am at the newest level of the Rom and seems that after 3 or 4 release ago this started. Phone will not switch from LTE(data) to WIFI or From Wifi to LTE(data). I have tried to turn off Wifi and then back on as well as the LTE but never switches. If I turn on Airplane mode and then off it used to switch but now the phone reboots then I can connect to Wifi or LTE.
TIA
