I am afraid your Note 2 will be just not enough efficient.

Since I am having the same issue with my son's S5, I can be sure, that this is not a problem of my Note 2, but with a buggy PilotApp.

Get Cool Tool and check Your CPU usage.
Maybe you have other app running in background which consume CPU time.
I have downgraded Google and removed any other bloatware and everything works fine at now. However i am using my tablet only for Phantom.

On S5 this is problem of Google Services and bloatware, and on Note 2 this is problem of overall efficiency.
You can strip S5 and gain CPU power for DJI pilot, and on Note 2 you have no CPU power at all. You can try onnote 2 our workaround, however i am not expect revelations

I googled around a bit and found some other folks having issues on Android with the location services being in "assisted mode" (both GPS + network) causing high CPU usage in some circumstances.

Based on this I tried changing my Nexus 9 to "device only" mode (which only uses the GPS.)  This seemed to solve the CPU consumption issue and restore the normal responsiveness.  You can make this change by running the Google Play Services app and looking through the options it presents.

I haven't been able to do any serious testing on this other than connecting to the drone and moving the camera around, but at least for now it seems to fix the problem.  I'd be interested if others have success with this.

For a good test you can turn on Cool Tool monitor with CPU usage, and get values with downgraded Google Play Services and with your settings.
Of course you need to make it outside where you get lock at least on 11 sattelites (more is better)

Same problem here with the freezing/pausing video, but using an Ipad Mini 2. Problems started after istalling the latest firmware (1.2.6 Phantom 3 Professional), so it is not an Adndroid issue only I suppose.
Made some test in open fields, more trees and buildings etc., but it happened randomly in all situations. Hope the update is comming soon. This is no fun at all.

Ok, i tested it. I went outside, got 15 sattelites.

It doesnt matter what option i use i have 85% CPU load with latest google services and little stuttering when i moving camera up and down.
If i downgrade them i have 65% CPU load and everything is fluent.

Ok, so I did some playing round tonight and found that it happens on my iPhone 5s when it gets too hot.  I let my P3P sit on the table with the controller and phone hooked up.  Motors not running, just everything connected.  Video was fine for about 10 min...I was moving the camera around most of the time. Then the video goes laggy.  By this time my phone is pretty warm to the touch.  I take it over to the AC vent and set the phone, still hooked to the controller, directly on the AC vent.  Within 30 seconds the video was fine again.  Took it off the vent and in 10 min or so the video started to pixilate.  Put the phone back on the AC vent and, again, in 30 sec or so the video is fine.

So my semi educated guess is that this is nothing to do with the firmware, and everything to do with the app.

Flying this thing is just not fun anymore. I took it out for a quick flight at my favorite spot, FPV lag so bad I brought it back home.

The primary reason I purchased this UAV was to utilize my Android device and fly FPV, as was advertised by DJi.  Ever since the release of 1.1.9 FW, my flying has not been an enjoyable experience.

It has been well over a month since this issue of FPV lag/freeze was reported on this forum and no fix yet.  

I have tried every suggestion to remedy this nagging issue, al to no avail.
Stop this, start that, use mode this or that mode, place Android device on a block of dry ice, put it in the freezer, etc....DJi launched this product to work with an Android device. Now its got to be a device with the power of a water cooled desktop PC.

Come on DJi, give us some hope...

Updated to 1.1.9 on May 22.  No problems prior to the update. I have experinced issues ever since.  I have also installed all subsequent updates hoping for a fix. I wish I could roll it back.

It's been over 5 weeks.  Supposedly DJI is aware and working on a fix (per responses from DJI in this forum).

How about a status update on your progress in a fix DJI?  When will we hear or see something?

Doesn't work on my Acer Iconia tablet ... video stream doesn't go anywhere (bitrate stays at 0), audio bitrate at 700.

Tried on my wifes Galaxy S3 phone, worked, but choppy and eventually crashed the phone, haha.

Android device complexity and variety aside, I use other apps for streaming other video cameras and things I have and none of them have issues, so I'm guessing its just a coding issue.

@DJi: GUYS - TAKE ANY GOD**** ANDROID TABLET, RUN YOUR OWN ******* APP AND FIX THIS PROBLEM NOW!!!
I cannot believe that!!! I am really thinking about giving back this otherwise fantastic copter within my evaluation period. It cannot be so difficult to run a diagnostic app on your pilot app finding out what the problem ist, can it? Plus: It started with 1.1.9 - so there had to be something you introduced with 1.1.9, that wasn't there before. Whatever you "improved" in 1.1.9. - JUST TAKE IT AWAY, PLEASE!!!!

Does that mean we'll be able to downgrade back to 1.1.8 after we install 1.2.9?   Or does it mean we can only go from 1.2.9 back to 1.2.6 or 1.2.8?

No a very clear statement. More details if you have them.

I have had the freezing problem with my P3 since 1.1.9. The Samsung Galaxy tab s should have enough power to run FPV. I am leaning towards a gps cache problem, but that' s not the reason for my post. I have put the P3 away since I can't trust the FPV. I have been flying my Inspire 1 and it never has any freezing. It appears like similar software, why not just apply it to P3?

Same here, even I have FPV LAG after 1.1.9, the statement from DJI was in Chinese, so after translation, it wasn't very understandable, anyways according to what I understood, right now we can only install a firmware that has a higher version number (incremental+), but once 1.2.9 is released, we can probably downgrade  to anything we like, they also addressed heating issues, and some other issues too, so 1.2.9 should be coming soon, hope they add SDK support for 3rd party apps too! ☺

As i am understood, 1.2.9 will be 1.1.9 because there is no technical possibility to downgrade to 'lower number', so 1.2.9==1.1.9. Maybe I am wrong, translation from chinese is like black magic for me and chinese letters are just like symbols like circles, dots, driangles, lines. Without translator i feel like a 2 years old child in library.
If i am correct, there is nothing reason to be happy. If somebody directly from China could translate this statement it will be great.

For me the lag is solely down to the dji pilot app, i'm on out the box firmware 1.1.9, app version 1.1.0 no lag
Updated the app to 1.2.0, same firmware, same tablet, same play services no changes other than the pilot app updated, 3-5 second lag and flickering on live view.

Reverted back to pilot app v 1.1.0 and lag is gone.
