And tooth fairies are real... I am on a iPad Air 2 and having some serious lags.

Works on my test setup, no lag at all:

-Ipad Air (1), Phantom 3 (arrived Friday pre-installed with 1.1.9)
-Video Caching ON
-Hardware Decoding ON
-Firmware 1.1.9
-WIFI ON (connected to my home WiFi)
-Cellular OFF
-Do not disturb mode ON
-Bluetooth OFF
-Airplane Mode ON
-DJI Pilot app default settings (except for settings above)
-Ipad Air 1 got rebooted before flights
-64 GB Sandisk SD card UHC1


Maybe if we all compare settings it might help DJI figuring out the issue, or at least find a pattern behind it.
I have seen no stuttering in the last outdoor flights I did, smooth as butter.

Did you turn off video caching?  That will help as well.  My iPad mini get very hot.  Last summer  ...

Tahoe Ed  blade strike and I discussed this problem last week blade strike relayed to dji what I found dji knows what the problem is I found it the moment the latest software came out in android the java is looping no settings no amount of cooling your processors will cure this dji will fix the app. There are tentacles to the problem that I hope they find and cure also ie: wifi direct. please check dji data from barometric sensor I have also been working with samsung on lollipop issues. I have a samsung tab s on 4.4.2 with no samsung software in it running perfectly smooth no delay no heating no java looping 20 min. flights I have also another tab s on lollipop that displays all the  problems listed in this thread wont work at all I can fix but I am waiting till dji releases new pilot

It's not just Lollipop - although you seem to have discovered that made things much worse!
And it's not all DJI problems either.

The problem is a lot of users are jumping up and down and piling on without even doing a bit of homework on their android (or even IOS) devices.

I use KitKat and had lag problems until I used Zapper and turned off and removed all the bloatware.

Some here are complaining about their 2012 non-approved tablets.

I think DJI will constantly be able to improve the software, but that's not going to help the thousands of new quad users who are not approaching this pursuit from the "hobbyist" angle that longer term R/C pilots are accustomed to.

On one hand we have the most advanced and reliable machine - by far - than most of us have ever seen. On the other we seem to have a new class of buyers who not only expect everything to work like military-spec equipment, but aren't ready to put in time and energy to help solve their own problem.

The same people then demand that DJI fix complex problems - many involved Android itself - in a couple of days.

New buyers should know this. The Phantom 3 will be perfected in about 6-8 months....about 3-4 months before the Phantom 4 comes out. That's the way the evolution of aerial robotics has been happening.

DJI could instead  - like some other makers - release machines that are a year behind the market instead of a year ahead. But they push the envelope....so their quads are more powerful than many tablets and phones can handle.

I do design on medical devices. Frequently we have to also supply the computer to run the analytic software on, however the computer needs to be hardened due to the environment its used in. Purchasing a cutting edge toughened laptop computer is an oxymoron.

For DJI to spec out a ultra high end FPV devise for use on the Phantom would have been counterproductive as a large segment of the prospective purchasers would pass on the sale.

DJI has a list of recommended phones and tablets for use as FPV devises. Are the higher powered units going to operate better? Probably, however all of the recommended devises worked on both the firmware and the FPV OS that was offered at the time of design.

For now, DJI Has a lot of software de complication to perform to debugg their code to find the offending line or lines. The Android system doesn't help as there are over fourty versions of KitKat, all custom modified by the various tablet manufacturers. Contrast this with the Apple IOS only having three versions of IOS 8 including the security updates to 8.3.

Please don't bash other users as we are all CUSTOMERS and we had a working app on firmware 1.1.8 and now not working on 1.1.9 so go figure.

We do not need to do homework, the thing has to work as advertised thats why we freaking paid this lump sum.

on my iPhone 6 plus i can't do more than 10 minutes or it starts to lag and phone overheats.
on my nexus 7 2013, i had deleted the rom and reinstalled a stripped down rom with no google services and used the freaking zapper and still lagging on kitkat.

Most of us are educated people not fly boys wana play the thing in the air, so please don't waste our time with this non constructive talk.

Have you turned off bluetooth, cellular and wireless and quit all other programs?
Enabled hardware ...

Yes I've turned off bluetooth, cellular and wireless and quit all other programs indeed, I'm not a novice at tablets or computers I do my own encoding for a living and write programs so I'm sure I'm better at it than 99% of the people on here, it's how I make my living for decades, I know it's the firmware trust me 1.1.8 is perfect regardless of how hot the tablets ran & yes I enabled hardware decoding too..

We are beating a dead horse on the head with a stick every time someone posts, the temporary solution to all this is to roll back to 1.1.8 until they have a permanent fix end of story. Just cause your IOS works great and his Android works great it will NOT BE THE CASE with everyone as proven by many.

I will tell you why since you mentioned it, the flight controller on the phantom 3 is not as powerful as the one on the inspire and with the firmware 1.1.9 is taxing the phantom more and i felt heat coming out of the phantom even if not flying just sitting on my table, so it is not the tablet problem, it the firmware 1.1.9 is buggy on the phantom.

And one thing about task killers software.

In some cases they can do more bad than good, because they will killing apps in some interval and these apps will try to start in some interval and this may cause unpredictable CPU overload and video lag or freez when you are not expecting that, and you may crash drone finally.

It is good not to kill processes in interval but remove and turn OFF application which are responsible for those processes.

Yes, true!
I did go into the settings and tried to completely remove or disable as many apps as possible.

It's probably advisable to sign out of google -if signed in - because that definitely uses a lot of cycles.
People can turn off the "update apps" in the google play store settings and other stuff like that.

I knew I had a problem when I saw 7 icons up in the upper left of the screen. If the device is fairly well stripped you'd only see one or two.

Makes perfect sense.
You can't expect the same product for $1K that you can for 3K.
That extra money buys a lot of RAM and CPU cycles, etc......

It makes sense that a lot of tasks would be offloaded to the smart device....even if we all had to go out and buy a $200 newer device, that's much cheaper than spending an extra $500-$2500 on a quadcopter.

My wife has an iphone 6 and ipad air 2, but I haven't the heart to steal either when I fly so I bought the moto-g and now have a 2013 Nexus on the way - both are dedicated. My phone is the iphone 5, which won't do the job. Maybe I should trade it in for a 5s just to experiment....

"even if we all had to go out and buy a $200 newer device, that's much cheaper than spending an extra $500-$2500 on a quadcopter."

um no not really. Now we are approaching 3DR solo price range. And if the best in Apple hardware is still having issues (ipads overheating, rebooting, app disconnects) a $200 device aint going to cut it you need the new Air 3 or Mini 4 which is going to be $500 - $700 range if you want GPS and follow me. I am waiting for a newer device if I even stay with DJI.

I am really interested to see how they deal with this issue, tax the craft too much and it will have issues, tax the device too much and you get lag and crashes. Quite the bind to be in...

I am sure they deal, because problem was appeared in 1.1.9 in most, so dji cpu power is not  responsible for that.
People, espesially with Galaxy Tab S tablets, reported it works fine on 1.1.8.

Hi, may I ask if you are still on kit kat? and what about your lag? you are lucky busy 1.1.8! and I suppose you can fly fine. A little video lag but acceptable I think.
Any case I did a kit kat downgrade on my tab S 8.4, it's better than Lollipop but unfortunately I'm on 1.1.9 now. With the 1.1.8 and kit kat was good. Not perfect but good.

I do not think this is going to get fixed easily or quickly.
I am pretty upset about the whole thing. No Youtube streaming on Android or the Training app. Not deal killers but we didnt know these would be possibly added later for android users.
And the whole lagging issue has kept me from doing anything serious with my p3. How can I line up shots when the video is freezing and lagging?
I think I truly want a refund. Product rushed out the door before it was ready.
