Multitasking Video - Screen or UI seem unresponsive
 

[I have searched for a thread about this but couldn't find one]

This video on youtube raises some concerns with me about the screen and/or OS performance.

I've heard reviews say the screen is great and the OS is very quick but on the evidence of this video something is not quite right.

Has anyone with an N900 experianced anything similar?
He doesn't seem to acknowledge the issue in the vid but you can see him having to press multiple times to get a response.

Please note that I'm not trolling for a reaction. I like Nokia phones and am very hopeful of the N900.

Re: Multitasking Video - Screen or UI seem unresponsive
 

My (prototype) N900 sometimes just doesn't react to normal finger presses, but works once I use the nail. However, strangely this seems to be mostly limited to the desktop and the program selector; I guess it is a implementation issue there. I never encountered it inside Apps.
OTOH my prototype can get sluggish when busy with phonecalls. Yesterday, I was even unable to finish a phonecall, because the GUI hung (first time in a month). Had to remove the battery...

However, I'm really abusing the device in terms of devel-software, data and teststuff installed, so really trying to get to the limits. I have 2500 songs on it, a few hours of video and over 1000 pictures.

This device is really a powermachine: You can e.g. use your browser to get a torrent, then get the torrent DivX and watch them with the inbuilt Media-Player...

Thanks for the info.

I love the capabilities of this device but I've never been comfortable with touch screens. I'm more into the E71 form factor but can't say I like the look of Symbian.

I guess I'll have to give it a try before I buy.

Re: Multitasking Video - Screen or UI seem unresponsive
 

People are somewhat used to capacitive touchscreens now which I think is the problem here - people press lightly and then realise they need to push a bit to have it register.

Re: Multitasking Video - Screen or UI seem unresponsive
 

Yes, it looks like he is touching the screen "wrong".

Re: Multitasking Video - Screen or UI seem unresponsive
 

Depends on your definition of 'not right'. Jumping between half a dozen web pages and various open apps, media player playing back stuff in the background and youtube to top it off DOES adversely affect response time, but I'm not sure what people expect here, youtube (flash, to be more precise) can do that alone on a full-blown netbook.

IMO What you see on the video as unresponsiveness is not a capacitive/resistive press harder thing, but rather the N900 swapping in and out the various pages/apps (if it was just presses, the task-switch animation would be smooth).

Here is a good example why the 3430 and its more robust DSP is a better solution than snapdragon:

Re: Multitasking Video - Screen or UI seem unresponsive
 

Hi rpcutts, I created that video based on a request in another thread. I think you are the one who commented about the unresponsiveness. I just replied to that comment.

The reason for the appearance of unresponsive was because I couldn't press the tabs correctly when holding the camera on the other. This is the first time I have ever created a video about a device and I am surprised with the number of views it has generated.

Anyway, I will put up another video with a better setup that will allow me to shoot and operate more easily.

yes. I am working on my ambidextrity :o

Re: Multitasking Video - Screen or UI seem unresponsive
 

I think there's a thin line between a normal user's multi-tasking and plain out forcing the device to slow down.

Personally, I would use 4-5 browser tabs for facebook, gmail, maybe a flash webpage like youtube etc. On top of that, I might listen some mp3s, have an open pdf document, and also have a couple of ongoing IMs.

However, I would not listen to music while watching a streaming youtube video, nor would I launch a game just to see what happens to the device.

Desktop-like performance means multi-tasking reasonably considering that the processor is single core. It does not mean running every single application there is at the same time and expecting no slow down.

Re: Multitasking Video - Screen or UI seem unresponsive
 

Thanks for making the video, archebyte. Let's put it this way: this certainly isn't the video that I would show off to iPhone lovers to show how great multi-tasking is on the N900!

Re: Multitasking Video - Screen or UI seem unresponsive
 

to me it seems the video itself is a bit the factor as everything on the video seems to stop for a splitsecond, so this is not only the n900 not responding in this case, its the videos quality... to me!

Re: Multitasking Video - Screen or UI seem unresponsive
 

hey who said the device was supposed to run 15+ applications smoothly, as the memory or the processor get clogged, the device will slow down.

It's up to the users to manage their multi-tasking, what Maemo 5 has given you is a very easy and intuitive way to manage that.

Now in a more scientific way, I'm not sure how we can discover the limitations of the N900 in terms of memory, or processor (and even video).

Are there any benchmarking tools available? Even with such a tool it doesn't answer everything as keeping multiple applications optimized to respond effectively to feedback requires optimization of a different kind, one that cannot be overcome by brute force processing power easily.

Re: Multitasking Video - Screen or UI seem unresponsive
 

Well... you can see this as a good and a bag thing at the same time...

Good thing is that the n900 has, clearly, set the bar higher from those times from iphone (rememeber? iphone? could not even multitask pfff....) So by pushing harder and harder this mobile/computer/tablet/horse with a sword on the head-thingie is a clear sign that people are clearly understanding what it is to have a mobile/computer/tablet/horse with a sword on the head-thingie in their pockets. Different from the iphone times.

Also nokia will get much much more feedback once the n900 hits the streets (much more than with the previous maemo devices) and they will for sure build with this experience.

The bad thing is engadget.... I just dont like them dot.

Re: Multitasking Video - Screen or UI seem unresponsive
 

I have a Summit N900 and it acts exactly as in the video when I get overenthusiastic on the number of open flash sites :) Same happens for example when I do media playback + RSS refresh (and have a LOT of HUGE RSS feeds) + surf. Swapping and writing to the eMMC at the same time simply makes things choppy - but that is to be expected.

Re: Multitasking Video - Screen or UI seem unresponsive
 

That's something very different (at least on the beginning of the video). He's not returning to the tasks, just launching them. You can do that on the N900, too. Another question is just how concurrently the tasks in the background are running. Also, there I see no flash in the mix there, which makes a huge difference.

Re: Multitasking Video - Screen or UI seem unresponsive
 

I thought the HD2 did not do real time multi-tasking but just rather pauses the state of the application when closed. N900 is real time multi-tasking isn't it?

Sexist much? Oh, that's why it's God, not Goddess. ;)

Re: Multitasking Video - Screen or UI seem unresponsive
 

The latest video from archebyte is much better, the commentary really helps to explain whats going on.

I can't tell, but seems this time archebyte is pressing the screen more firmly to register better responses.

Re: Multitasking Video - Screen or UI seem unresponsive
 

i have to say, that 2nd video is pretty amazing. Things are still a little laggy/jittery at a few points (eg youtube), but overall quite nice imo.

Re: Multitasking Video - Screen or UI seem unresponsive
 

thanks for the plug. this time the camera was properly mounted so that the N900 could be used with both hands. The presses were more firm than the previous video because I was being careful. I don't follow the use-case demonstrated in the video routinely. :rolleyes:

They can get the X6.

Re: Multitasking Video - Screen or UI seem unresponsive
 

Thanks for the second video, archebyte. Still a few places where it didn't respond, I notice, although not as bad as on the first video. By the way, you don't need to double-click to switch to apps in the dashboard ;)

What's happening at 6:53 when the dashboard thumbnails zoom out to much smaller than usual and the screen seems to hang for 10 seconds?

@tito_66: the phone app doesn't go into portrait mode if the keyboard is open.

Re: Multitasking Video - Screen or UI seem unresponsive
 

Yup, I know only one click is required. as I menitioned previously, just taking extra caution.

Yea, I am not sure what happened at 6:53. usually the thumbnails after 12 apps start stacking up on the fourth row and a toolbar appears. this time it seemed to have zoomed out twice.

Re: Multitasking Video - Screen or UI seem unresponsive
 

i think its because the keyboard was open... which overrides portrait mode... since by having keyboard open it assumes ur on landscape.

The N900 makes multi-tasking look like a child's play. ;)

Has been posted a few times, thanks anyways :)

This was posted several times. Thanks though.

hopbeat you got me :mad:

Ok, sorry about that then. :(
