    I'm sorry you're not happy with your phone and I would agree that you should try for a replacement or another model phone rather than living with it. Like most others I'm very happy with my 830 (came from an 822) and I'm not experiencing any of the problems you're having or I don't perceive them as problems.


    To describe the delay part better, try this for yourself, swipe slowly to bring up the app list and u will notice that your finger can slide across the screen for a millimeter or 2 (maybe 1.5 lol) and nothing will happen. Now when u do this in a faster motion, there will be a slight delay in the animation. it's not a huge lag but still noticeable
    This "problem" is an improvement to me. On my 822, I would get an inadvertent swipe to the App list if my initial scroll on the Start screen wasn't perfectly vertical. This never happens on my 830.

    • backlight intermittently dulls and brightens
    I believe turning off the automatic brightness level will stop this. (Setting>Brightness>Automatically adjust>Off)

    Flash uses a lot of juice. Don't use flash for your photos if it's at all avoidable. If the subject is motionless, then stabilize the camera by placing it on (or bracing it against) a stable surface before taking the picture. That will allow the sensor to measure light over a long period of time and result in a great picture. Not only will that avoid the washed out flash look, but your battery will last longer too.
    Flash + Battery life are mutually exclusive on any device.
    2)
    Don't uninstall facebook. Keep it and wait for an update.

    Beyond those two things... no, I can't say my 830 is experiencing any of the difficulties you are.
    Being a bit more specific about when and under what circumstances you encounter loading screens /jitter/lag (or a video), might also help us to better help you.
    Actually long exposure does really use a lot of juice, if that is what you're referring to. It may even use up more energy than LED flash, but not more than xenon (which the NL 830 doesn't have). Also, long exposure results in sensor heat, causing thermal noise. It will result in better looking photo no doubt, but it does not freeze subject movement (though... LED flash does not do that very well, but you get my point).

    If you just got it a week ago and it's clear that's not the prevailing experience, why not just take it back for a new one?

    waaaat...Facebook and WP Central apps never showed any issues here lol

    and i haven't experienced any issues related here too...also my battery life os always around 1 day!

    i do think you have a faulty device and should get a warranty exchange!

    You have anything to back that up with? I'm not saying you are wrong. It's just my gut feeling that a CCD sensor probably uses < 30 mA and I'd expect a LED flash to use at least a couple 100 mA. I'm skeptical about your claim...

    I will answer what I can. Thanks all for your replies. I am happy to do a hard reset once I can figure out how to back up everything.
    TBH if you do a hard reset, you should NOT restore anything from a backup! At least not initially! Restoring from backup may just reintroduce the problem you were trying to get rid of with the hard reset!

    Instead, after doing a hard reset, just install the most important apps from the store (three or four), and then use the device for a day or two as is. If it then doesn't work it's almost certainly either firmware related or a faulty unit. Only if that works would I consider restoring the backup.

    I agree 100% with the OP.
    Everything he stated is happening on my 830 and on my girlfriends 830, went back to the store and checked the 830's on display. They all had it!.
    Some people keep defending they're 830 and i can relate to that, but comon people, this phone is not optimized as should be and IS doing everything the OP said! Compare it to an 820 and you will see, do you guys not see the same i see? U have magic phones? wtf

    The jagged scrolling is the biggest issue in my opinion! I hate it. coming from a 820 that is what the eye catches the most. this screen is horrible, oversensitive or whatever i really don't know, but it's not the windows phone experience i was used to and hoping for when i purchased this phone!
    Got a 830 for my mom a little over a month ago, running smooth and all's well, her battery lasts for 2 to 3 days (she doesn't use data plans though, just wi-fi).
    You guys should really try a hard reset, if that doesn't help, try returning it to the store for a new one.

    I just got my 830 last week. So far the problems I have had are:
    camera won't always zoom
    very very poor reception compared to my n900
    poor battery, not even a full day, taking photos with flash, a couple of calls and some web browsing
    windows Facebook app keeps closing so I have uninstalled it
    web page Facebook doesn't for on the screen until I go into a post and then back to the homepage
    intermittent scrolling lag
    backlight intermittently dulls and brightens
    jagged movement with scrolling
    very often have the loading screen, sometime pages won't load
    very often have the resuming screen
    gets hit quickly
    The only things I like are the swipe function and the phones size.
    Is my phone a lemon or am I expecting too much or doing something wrong?
    Let's see ... Here are my reactions based on my 830, which I bought 7 weeks ago today.

    Camera sometimes lags before zooming, particularly if I have just started the camera.
    Acceptable reception. Perhaps a little worse than my iPhone5.
    Good battery life, lasts all day with normal use - a few calls, several texts, some googling.
    No problems whatsoever with Facebook, which I use a lot.
    No scrolling lag.
    Backlight sometimes dims when I first awaken the phone. After than no problems.
    No jagged scrolling.
    Web pages occasionally don't load.
    I don't know what this resuming screen issue is.
    I don't know what "gets hit quickly" means.

    I really don't have many complaints, and I have no reason to defend the phone. This is my first Windows phone, and I have encountered some frustrations but all in all it's a slick device and a great operating system.

    Actually I used the word "may" because I wasn't too sure, though grammatically it should be "might" xP. The only claim I made was that long exposure uses up a lot of battery, which you can easily find articles online about it. I used "may" because it is not a comparison that can be done. For example, "long exposure" does not contain any length of time in it. Also, the length of exposure also depends on how much the flash illuminates the object (depending on distance).

    Can I ask you how did you quote a value of <30 mA? Also, IIRC, Lumia 830 use BSI CMOS sensor, and not CCD's, as with many smartphones nowadays.

    I have a degree in electronics engineering (although that's not what I do these days). Those numbers I provided are just my estimates, nothing more. I also admit that they may be outdated. I don't know. That's why I asked what you were basing your opinion on. I went with a CCD because CMOS sensors tend to use even less power. I'm not saying that powering the imaging circuitry is cheap in terms of power drain. It isn't, so I'd agree with those articles. I am just very skeptical that power drain is anywhere close what it takes to drive the flash, at least for typical exposure times.

    It's also the reception that is a huge issue for me. I have been without reception around 10 times in 2 days and with my n900 I would have had less than 10 times in 2 years.
    I can barely use this web page on my phone, it's a super pain in the ****. Can't zoom, takes forever to load anything and when I tap on something you can't tell if it's working or not...
    Basiluzzo - what facebook are you using? And I meant hot not hit!!

    I suspect the low battery life is a result of your reception problem. If the phone is constantly searching for signal it can drain more power than if it's always connected.

    Most reviews say the Lumia 830 runs cool unless under a heavy load and/or charging. That's been my experience too. My fingers felt like they were freezing against the metal frame haha.

    Anyway, it's impossible to say if you've got a lemon unless you have another Lumia 830 to compare to.

    This site is not a good place to test mobile IE on WP with! You'll find a million other sites that work just fine. Claiming mobile IE on WP doesn't work well because this site doesn't perform well, while a million others work just fine, is a bit of a stretch.

    Many issues on the devices come as a result of very poor quality control.Nokia and now Microsoft don't give a damn about carefully checking these phone models before releasing them. I for example, am stuck with wp 8.0 on my Lumia 1020 because of the freezing issues that appear on 8.1 on this phone and on the 925 model. What can I do? Nothing, as long as Microsoft does not care at all about quality. It runs perfect in 8.0 so the device is ok, but on 8.1...

    No wonder after all L830 have SD 400(a budget phone processor)
    It has same processor as L630(except RAM) so no matter how fancy build quality or additional feature it got, at the end of the day performance will be same as budget phones.

    L830 is all about looks & additional features than performance.

    "other people aren't having the same experiences I have? They're lying or have magic devices!"

    I'm curious as to how you tested a number of those things on display models (how you tested battery life has my interest), but perhaps you shouldn't be comparing your buggy phone to a display model (which is abused and ruined by hundreds of people a week). That will give you confirmation bias for certain :)

    I suggest you look around the forums for a guide on flashing.

    That would make sense, if any of the things being complained about required anything more than minimal CPU and GPU performance. The notion that tapatalk, or the battery saver app, scrolling a page without massive lag or jerkyness should require anything more than a budget phone is simply ridiculous. That others, including myself, can't reproduce these issues on our own devices should be proof enough that this isn't a general, performance related problem. Obviously, a country specific bug in firmware could possibly cause a critical performance hit, so lag/jerkiness may be a performance issue in that sense. However, in that case the sane solution would be to fix the bug, rather than to just throw more powerful hardware at it.

    Hi, Im new on this forum , but Im and older reader of WC.

    I just can say that the lag he might say it could be about Denim ,I say this because on my L720 since I upgrade to Denim Im having some scroll issues that I"d never had.

    And talking about the lag on some App, or the reboot on those App, have you considered the microSD card? Why Im saying this?.. Because I also notice the Camera App, somes games and other apps( like fb, tweeter,etc) take a long time to launch when before doesnt, i get a new microSD card SDXC class 10 (because mine looks like star to had some problems) and I changued to save the pictures to my pone and the apps crashed desapear.

    Idk if this may help in something!.

    Right, i have had my 830 for a long time now and i can say this, if you get microstutter then there is something wrong, i am personally hugely sensitive to stutter of all kinds and the only time the 830 should stutter is in very heavy games or poorly coded crap apps or having cortana pinned to start.

    Unless you are running Dev preview, i ran the preview for a while and it did introduce massive ammounts of stutter in animations, almost as if the refreshrate had been lowered to 30 from 60, or an odd number like 45. I tried staying as long as i could on the preview but an update later and no change i jumped back on stock software and all was fine again. In regards to battery life the record for me is 5 days with wifi running, 2G network and cell data enabled, this was mostly standby apart from the occasional wakeup. With frankly insane usage you should get around 5 hours (nearly constant full load) and with "normal" heavy usage easially a days worth.

    I have compared my 830 to most flagships of today and except for other win phones (930, 1520) there is nothing that has the same fluid feel in it's OS and handling. As stated earlier, if you have reboots, stutter, hangs, and so on then something is most definetly wrong, it could be hardware (broken/incompatible sd card makes this phone go bonkers) but more likely it's a poorly coded app.

    In regards to your problems with reception it can be a few things, first would be if you use a case/bumper on this phone it will reduce the signal by huge ammounts, this could be down to how the antennas are placed and handled. Another is what network you are actually using, manually choosing a network can be a very good thing, if you want to go further then choosing the type of network is even better. I live in an area with pisspoor reception and without my GSM repeater running nearly all phones will loose connection from time to time and on the frequencys used here my 830 outperforms a Z3 compact with ease (along with nexus 5 and iP6)

    Some of your issues have been addressed above, but the mention of micro stutter makes me suspect either a poor app with some issues, or as posted above that you're on the developer preview?
