Is there any end to your arrogance?  Give it a rest!!!

Wait - you said to ignore you........and now you are stalking me?

Give it a rest, man. It's a public forum and I am gonna be here forever.

Someday maybe they will have an "ignore" feature. Until then, if you don't have anything kind or helpful to say, you should be quieter and learn something.

In other words...........

I've had my video cache capability disabled almost since day one. The incredible video lag others are experiencing is my result as well. During testing late yesterday, I slipped the camera back and forth between 0-degrees and 90-degrees (one of my C switches does this). A lot of the time the video display never acknowledged I had moved the camera, i.e., there was so much lag it never caught up.

wich version of dji pilot did you use?

I think that if you roll it back you still have the maps, I dont think you have map feature if you disable, I shut off wifi after getting everything going so the update is not annoying,  My wireless fpv glasses turn the direct wi fi on to them only , when I use them works great.

Scotty t I probably will keep my p3p thanks to you,  thanks again, also I am not sure about the kit kat thing being better I have two tab s 1 kit kat and one loliiflop, I have rolled both back on play services, I am going to check let you all know.  The reason I say that is when I first loaded  lollipop, I was excited because I had read that the video in lollipop flowed better, I assumed that applied to the P3P,  not .  but I did notice that other video flowing on the tablet seemed to be better,  Now how but some help on my alltitude problem maybe the forum research team could start a new thread.

Interesting. What version of Google Play Services do you have on your lollipop Tab S?  Still laggy  ...

I need to bit clearer.  I am the designer developer of the nebula alien sunglasses wireless FPV system for the phantom 2 and 3,  
  
    http://www.phantompilots.com/thr ... /page-3#post-395721   

It takes just a bit more to push wifi direct to the glasses , I can hardly wait for the p3p hdmi board, your fix is right on, ever thing works great there doesnt seem to be the developing processor bog, I do get a large number of satellites, sometimes 20, I used to only get about 9 max on my vision 2 plus. Maybe the software should select the best ten or something.

Here is a couple of things to look at.  the first time I used it I did get a little boggy when I  had everything connected, I have a task manager program loaded from play store by farouok  It came up on the notification that the processor had  been lagging for ten minutes " fix"  I hit the fix and the tab straightened right up,  that has not shown back up.

Also on the tab s under the developer tools there is a setting that limits or shuts off the number of backgroud programs that are allowed to run. I set that at 0, that seemed to help, needs further testing,
There is also another setting , "force 2d gpu rendering"  not sure about that feature, need to look at.

I do not belive it is happen. let me someone wakes up.

The new app is slightly  worse than old. It consumes a few percent CPU power more than old.

Google play services are broken as in 1.1.0. Nothing change, i do not know what is better, back to 1.1.0 or use 1.2.0, both are bugged and 1.2.0 more laggy.
Thanx to God an Google Play services downgrade workaround is still working.

Could somebody from China, living near DJI HQ go to them and stand by them for a few days and few night until they fix something?

From changelog:
"Various bug fixes and optimized performance"


Someone who wrote this is crazy, or he have very excentric sense of humor.

DJI, we don't care this director mode or voice battery level warning because we still cant fly, really. Please fix it.

This is behaving as expected - Apple states 95 degrees as maximum ambient and yours was likely heating up to that or more after 10 minutes.

You'll have to cool the device somehow if you want it to operate for longer periods in very hot weather.

I install the new 1.2.0, and all is worst.

Now WITHOUT SATELLITES I have lag.

Incredible......... the worst app ever with the worst firmware ever.

And with 1.2.7 firmware the phantom only flight 18 min, while with 1.1.8 and 1.1.9 flight 21 - 22 min.

I flew with the new android app today, with Google Play Services DISABLED.  It works fine the tablet did not get too hot and there wasn't any video lag.  I'm not even going to bother trying to re-enable google play services until DJI addresses this.  I would suspect the tablet would quickly overheat as per usual using the new 1.2.0  android app and 1.2.6 FW with Google Play Services enabled on my Nexus 7 II tablet.  I just don't have the patience to keep testing this stuff anymore.

Suffice it to say that with google play services disabled, the new app works as well as the old one did with no overheating issues causing video lag.

Remove all bloatware, disable auto updates and disable/downgrade this auto update mate.
It should help a bit.
But it is true - app consumes a bit more cpu and it may cause lag on more loaded tablets.

I can confirm, this is working! I made the downgrade to Google Play Services and go to test fly it.
Lag was gone and maps still works ok, experience was like in fw 1.1.8.

Drone: Phantom 3 Professional
Tablet: Samsung Galaxy Tab 4 (SM-T535)
Android: 5.0.2
Google Play Services: downgraded to stock
Firmware: 1.2.6
DJI Pilot: 1.1.0

This can be the workaround until we get the fix from DJI.
Many thanks for Kyokushin for this workaround!

OK folks, there is my feedback after flying on new app.

Drone: Phantom 3 PRO
Tablet: Lenovo Tab S8-50 LTE
Android: 4.4.2
Google Play Services: downgraded to stock
Firmware: 1.2.6
DJI Pilot: 1.2.0

There was about 17-18 minutes of flying to 30% level of battery (at this level i landed). Pleas tell me peopole how is your time on 1.2.6 and what it was on older, i do not remember how it was on my 1.1.9. Time of flying to 30% battery.

It was smooth like a dream. No lags, no stuttering, just perfect and smooth FPV. Even on fast rotation or fast gimball moves. And of course map works perfectly.I recorded flight in 4K@25 and in my opinion it is smoother than on 1.1.9f/w and 1.1.0. pilot

CPU load was on about 65% and i have 20 sattelites.

Now I am almost sure than on Android platform, the main source of problem are latest Google Play Services.
DJI, please fix it, let comunicate directly to Android API, without Google Play Services.

I have uninstalled everything like facebook, g+, google kiosk, gmail, and other useless stuff, turned auto updates off, synchronizations off, print cloud off,  and downgraded Google Play Services.

The most gain is on downgrading Google Play Services (30% off CPU load) and removing facebook (8-13% cpu load)

In Lenovo i can just remove. If you cant 'remove' just turn off auto updates, downgrade and disable useless apps.

You can also use more specialized removing software like Titanium Backup, but disabling it should be fine.

And you may install CoolTool app to monitor your CPU and RAM usage (if it will be below 80% it should work smooth

I feel I must report as the original/creator of this threat that the rollback of the Google Play Services does indeed fix / work around the issue.

Firmware 1.1.9 firmware
Devices:  SAMSUNG S6 Edge (5.0) and Nvidia Shield Tablet (5.1)
Condition:  Airplane mode on or off
Recording:  On or Off
Distance:  Football Field or greater

Unfortunately I new issue with the VPS seems to present itself in which at landing in certain condition just before motor shutdown the PH will power up and roll.  Ill start a new thread for that ; )

Yes, i have it off, but i also flied with ON, i do not noted any difference.
Now i am very curious. The most of You claims than on 1.1.8 firmware it works fine (i bought my p3p with 1.1.9 so i do not know), and problems started on 1.1.9, but some of people claims the problem they have on 1.1.8.
maybe there is some correlation between releasing 1.1.9 firmware and this google play services laggish crap version upgrade. This CPU overloading crap can also cause overheating in some devices with a bit worse cooling system (because 85-90% loaded cpu is generating much more heat than CPU powrking on 60%)... and CPU is throttling down, what could be the cause of 4s looong lags.

Still works ok for me on my first test flight using the new app:

Drone: Phantom 3 ADV
Tablet: Samsung Galaxy TAB S 8.4 (also Oneplus One - Google PS downgrade was not needed for this phone. I gather it has more power to cater for the taxing processes)
Android: 5.02 on both
Google Play Services: downgraded to stock (otherwise laggy and eventually unusable FPV)
Firmware: 1.27 (also 1.19 worked ok once Google PS was downgraded)
DJI Pilot: 1.2.0 (also 1.10 worked ok once Google PS was downgraded)


I noticed some of the the options have changed and now one can't choose a custom channel nor restrict the streaming bandwidth if needed? In any case FPV streams very well even out to 1.5km in a paddock.

Hope to hear an update from DJI at some stage regarding all this. They're not very good with their comms are they!
