Does WiFi interfere with LTE, causing late text messages? I have heard this is an issue with Android 4.4.2, which is regrettably what my Note 2 is stuck with. Is there a way to roll back to a previous update and test the waters?

Sometimes my wife texts me with very important things and will get upset (we both do) when I end up with a barrage of text messages all at once from the past hour, which is extremely frustrated. I could have full bars the whole time and it happens all the time. It's not her phone's problem.

Also, I wasn't able to send MMS messages for a while for some reason. All I changed was that I got off of LTE and switched to WCDMA/GSM auto-connect, but I don't know why this would be an issue.

I am also on a custom APN, one that will allow me to only use data to receive/send MMS messages, because Koodo's garbage 50mb offering is barely enough to handle the odd time where Android will just start updating apps and stuff when I'm out and about.

Search "note 2 messaging" in the box next to new post at the top of the page.

Plenty of reading material and suggestions. Is her phone an iPhone maybe trying to connect to you through a now abandoned iMessage account on your end? SMS text messages normally don't need a data connection at all, but MMS needs mobile data (not wifi) to be active, and that's where your APN comes into play.

Set your google play settings to allow updates ONLY on wifi and you will stop the unintended update problem without tinkering with APN. If you want to go further, install a mobile data toggle and you can cut your data use substantially.


If you find the solution that works for you, please post back so that others can benefit.

There shouldn't be any problems with LTE (AWS) and Wi-Fi. Wi-Fi operates on radio frequencies' 2.4 and 5 GHz while LTE operates on 1.7 and 2.1 GHz. Switching from 4G (LTE) to 3G (WCDMA) shouldn't be an issue either.

There is a way to downgrade to earlier versions of Android; the caveat is that you may lose the patch for the Stagefright vulnerability. Before going ahead with downgrading, check your phone for a software update and take note of the current baseband version. To check go to: Settings > More > About device. From this menu you will be able to see the baseband version.


I don't see any updates for 2015 for the Note 2 on SamMobile, so I'm going to assume you have the latest update, dated: 2014-09-01, PDA/Baseband version: I317MVLUDNH2. If you see the same baseband listed here as on your phone, then you have not received the update.

You can downgrade to an earlier version of 4.4.2 or 4.3 if you're flashing stock firmware and don't have any custom ROMs installed. Start with a fresh install of the current operating system. After you've flashed the software and the phone reboots, skip through initial set-up phase and perform a factory reset from within: Settings > Accounts > Backup and reset > Factory data reset.

A fresh install generally clears up anomalies and serves as a way to troubleshoot to see if whether that version of software is the culprit or not. Head over to SamMobile and download the firmware/software file to your computer. Click on the software file you want to download. It's recommended that your phone have a minimum 80% charge before flashing firmware. You will also need Odin, a firmware flashing utility that writes the software to your phone.

The link to Odin is on the instructions page, (scroll down the firmware download page to see instructions).
