    I want to share my laggy experience using a Lumia 720 (512Mb RAM) with WP 8.1 DP

    Sometimes (lately more often) this is happening:

    When I am returning to start screen I am experiencing some random laggines. The animation of tiles wont display smoothly (as in WP 8) or the (live) images from the tiles aren't showing for half to one second after returning to start screen. And contact pictures are the worst, showing with a significant delay, one to two seconds.

    I think that this laggines is related to installing apps on sd. Because after I hard-reseted (twice) and I have formatted the sd (10 class) and installed basic apps only on phone memory all was ok. But after installing/trying/uninstalling multiple apps and games on sd card the returning to start screen became... not smoothly, that's the feeling.

    The thing is that I don't want to reset and reinstall apps frequently just to get those smoothly animations we were used in WP 8. (Btw, this is happening only when returning to start screen, the rest of the menus/screens are displaying as before)

    Do you experience the same?
    I was thinking to move to a Lumia 925, any of you guys using a 1gb device, how's your experience related to what I described?

    Same here.
    I think it may be because of show SD card.

    Oh, I hoped that 925 will behave nicely...

    This is a general issue on all 512MB devices. Nothing to do with SD card. Try removing the Cortana tile if you have it pinned (or make it small). It helped many people.

    No, Cortana isn't the issue. I don't even have it (or her ;) ) enabled.

    Never had that problem. I do live by one rule, whenever a big update vets installed a do a factory wipe and reload after the update and i have done the same after 8.1. I recommend you try that. I haven't had any issues unlike some of the other people here who have run in to issues post update

    I dunno. There was another thread where people removing the cortana tile helped. This issue is too mcuh present on 512MB devices. BTW, I had no problems since I hard reset a week and a half ago.

    I already did. If you please read the forth paragraph of initial posting you'll see that the phone runs ok after clean install. The problem came after some time and after normally using the system.

    8.1 needs better performance!

    happens on 920, it happens more often than WP8.0 yes 8.0 has the same issue from time to time

    Yeah for me it only happens with more tiles enabled (occasionally)

    In WP 8 the number of tiles wasn't an issue. The start screen was full of tiles, a long list of scrolling :). But now, in WP 8.1, I have no much than two screens of tiles but the lag is present.
    Oh, I forgot to mention that this is happening in both cases: with Show more tiles on or off (multiple columns or not).

    A way to temporary resolve this is going to a random page and then returning to start screen three-four times. It's like filling some kind of cache memory.

    yes this happened to my 720 too
    the problem is(I think) because of start background, I bet it not fully optimized for 512MB ram
    if your start background don't use background image(back to just colour), it will more smooth

    happen to my 1520 as well. I already perform hard reset and soft reset also having the lock screen not responding. Also frequently encounter the Start screen showing Loading... or Resuming.. then whole phone is warm and laggy.

    Maybe it's because we need the new firmware to optimize the hardware to the software

    seems to be rather OS issue than problem with particular device.

    Yes, I agree, its the SD card. I have a class 10 PNY, write speeds are only 11-12mb/sec and that's not fast enough. Games were horrible to play and using the phone was lagging at times. So I moved the biggest files to internal memory and kept the smaller apps on the SD card. Now my 1520 is the exact same smoothness of 8.0.

    That is a simple tweak that MS has to release with the Nokia Cyan Update

    Lots of lag all over the OS now. Not sure if MS needs to optimize the code some or maybe we've hit the threshold that starts requiring quad-core processors and more RAM. I have a Lumia 920.

    Still enjoy 8.1 tremendously, but it could be off putting for some who aren't used it.
