I have an Air2, running 1.1.9, no lag here.  Tried Auto and Manual video(ch20, 4mb/sec), video is clean, sharp, without lag.  I've gone out 7700 feet, and the video will get a little lag-but I think that's to be expected.
Sounds like an Android issue.  I have maps cached, hardware encoding ON-15 flights, 0 issue.  No lock-ups, no reboots, no loss of RC/Video signal-nothing.

I just got my Phantom 3, right out of the box I get wicked bad lag. I'm connected via lightning cable using my ipad mini ret. I really hope this issue is resolved fast. I'll be testing my iphone 6 and a galaxy tab 3, will report back later. I'm pretty disappointed right now.

I agree that is problem is only happening with the Android version of the Pilot App.  I am using the latest versions of the App and firmware.  Android device is a Samsung Galaxy S-4 running Android 5.0 (Lollipop).  The video latency and stutter is severe even when the drone is only 20 feet from me.  I have tried using auto and manual settings on channel selection and lowering bit rate.  There is no way to fly this safely via FPV with this problem.  It is an urgent and serious issue.  Please correct this as soon as possible.  Thank you.

Yes I have already mention it, this happens as well with IOS in my Ipad Air.
Havasuphoto has mentioned he can use FPV with IOS but that uses hardware encoder ON. I have flown with it OFF so far  so I will try with this ON tomorrow to see if it is related.
This is a very serious issue that renders the Phantom 3 only  safe in VLOS

While I normally run with my iPad mini 2, just checked my Samsung S4 phone with v5.02 firmware.  The lag was not different from what I am used to seeing, about 200-300msec at the worst.  I tried on both Auto and Custom.  I got no pixillation or dropouts.  I discussed this with Blade Strike and he tried it with a Note 4  and could not replicate the issues you are reporting.  I am planning on doing some flying this weekend with both the Inspire and the P3.  I will take them out 1-2km and see what happens.

I know this doesn't help much but I get lag and stutters regularly - with 1.1.8 (never updated from there).

BUT, I use an old weak and unsupported Moto-X - so I just assume that's the nature of having a cheapo device. It works OK for me since I ONLY fly LOS and have never used a camera to fly or navigate. I think I would quickly lose the thing if I did that.

Anyway, just another data point. Lots of freeze frames and stutters/lag (but I expect them in my case). It's important to separate out the real problems from those caused by older devices like mine, etc.

This thread now has 55 replies since I started it.   Clearly this is an issue.   Tahoe_ed no disrespect and I know you're trying to help as always.  But think recall,  i.e. like a car company having a tire recall,  the manufacturer realizes there may be an issue based on numbers,  even though not EVERY tire has the issue.  We can't dismiss the issue simply because a majority works.  If 80% of Android users have no issue and only 20% are affected that's still to high and probably excludes user error.

I work for Apple as a systems engineer,  I can tell you that between two top level Android devices the results are the same.  In both cases the lag started AFTER the last firmware update.  The results between the devices are identical to what others are talking about.  A Google search of "Phantom 3 Lag" also clearly indicates an issue.

When I had my iPhone 4 it was "AntennaGate".  I never had the issue myself but I could not deny it was happening either.

I also will say distance does not seem to be the issue.  Flying around a baseball size field,  even overhead,  will still present the problem.

We are all saying same thing, lag is probably due to 1.1.9 firmware. DJI need to focus on it.
Owner of Inspire1 never had similar issue updating various  firmware? It could help DIJ

Yes, I have the same problem, I have, while fliying, intermitent cuts / pauses on video streaming. And I only fly between 100 and 400 meters from me.

On 1.1.8 the phantom fly perfect, streaming perfect smooth, but when I update to 1.1.9 I have this problem.

I can´t fly well because the streaming pauses a lot, you can have an accident flying in this conditions.

Please DJI, let us downgrade the Phantom to 1.1.8, while yours reproduce the problem. 1.1.8 was near perfection for us.

I use to fly a Tablet Samsung Galaxy Tab S 8.4" (exynos CPU) and Samsung Galaxy Note 4 (Snapdragon CPU) and I have the same problem with both of them.

I test in the middle of the field, without trees.

Please please please, let us downgrade to 1.1.8

Thanks

What change did DJI in 1.1.9 to interfere with GPS and streaming. I can´t understand. GPS is one thing, and Hd streaming is other thing, but if you have good coverture of satellites, you have cuts on streaming video, If you don´t have satellites, you have a perfect signal on streaming.............I can´t understand........ but is real problem.

IT WORKS!!!!
I have flown today and tested with HARDWARE ENCODE ON and the problem seems to be fixed.  I also selected the HD Transmission  channel manually instead using Auto.
With this the FPV image was correct and very nice. Until now with Hardware encode OFF and channel selection in auto, it was extremely laggy and useless.
If you use hardware encode ON remeber to place your IOs device with App Background Refresh OFF.

I am very happy now!! I can fly my Phantom and see through its camera.
Those of you with laggy FPV image, I suggest you try this ;) It may work

Well if you read carefully the post on this thread and in othe forums, the problem was for both Ios and Android. There several posts of Ios users complaining about this.
Until today I could not use the FVP for flying using my Ipad Air. The image was extremely laggy with a delay measured in seconds, sometimes the image was frozen..... So I would say this issue is also affecting at least some Ios devices and it is not an exclusive Android issue.
By the way, did you made an effort to test the fix I proposed? ;)

Hey guys I was having the android pause lag. I formatted the SD card through the DJI Pilot app. Then I did a factory reset on my Nexus 7 and had a successful test flight with no lag and no app disconnects. It is only one flight so could be a fluke, but something to try, hope it helps someone else.

My Note 4 is basically useless for FPV, might as well fly blind for all its worth now

Same with my Galaxy Tab S 8.4.  It worked great a couple of weeks ago, but when it updated the firmware to Lollypop 5.0.2 the Pilot started crashing and freezing and being very slow.  I can't even set the video parameters or calibrate the compass without it crashing.  Definitely not ready to fly.

Blade Strike tested with his Note 4 and had no issues on the ground or in the air.  One user suggested that you Reset your device.  Turn off all other apps and disable video caching.  It worked for him.

Tahoe_Ed thank you for all, but that's nothing to do with it. My Samsung Galaxy Tab S 8.4 is like it has been reseted. It's brand new, no apps installed so ever. I just bought this tablet to work with Phantom3, I researched all best android tablets in the market, since I don't like iOS, and the only doubt was in nvidia Shield or Galaxy Tab S, and Tab S won the competition. So, I don't run any other programs and the system is like new. I even tried with airplane mode and its the same. The more GPS signal it gets, more stutter it become...

I really don't know.. I'm about to return my tablet to the store (if they let me, but its new) and buy a hateful iOS.. :/

hi,
i have some problem with my Multipad 4 ULTRA QUAD 8.0 3G(PMP7280C3G_WH_QUAD + Android 4.1.2).

time lag this not problem. i have FPV micro freeze.

What is the main difference in function between Android and iOS ?
I read somewhere that in the new firmware or a new DJI Pilot program(for Android) adds support for charging the phone(tablet) connected to the remote control. But iOS not have this function.
I think that is what is causing the problem!!!

We have tried to replicate this issue on a Samsung S4 and a Note 4 and neither of them displayed the problem.  I can only recommend that you call DJI and let them know your concerns.  I wish we would have had issues but right now we have nothing on our equipment that we can point to.  Some had reported issues on RCG.  Some have been able to fix them, some not.  Some are using non-supported devices.  Android is the wild wild west with manufactures providing their own skins to the Andriod operating system.  DJI can only test on a limited number of devices.
I am not saying that it does not exist, I am only saying that with the same devices that you say you are having issues with, we cannot replicate it.  We have reported to DJI.
