What is the best way to detect a mobile device

Question

Is there a way to detect whether or not a user is using a mobile device in jQuery  Something similar to the CSS  media attribute  I would like to run a different script if the browser is on a handheld device  The jQuery   browser function is not what I am looking for

If you use Modernizr  it is very easy to use Modernizr touch as mentioned earlier   However  I prefer using a combination of Modernizr touch and user agent testing  just to be safe   var deviceAgent   navigator userAgent toLowerCase     var isTouchDevice   Modernizr touch      deviceAgent match   iphone ipod ipad       deviceAgent match   android         deviceAgent match   iemobile        deviceAgent match  iphone i      deviceAgent match  ipad i      deviceAgent match  ipod i      deviceAgent match  blackberry i      deviceAgent match  bada i     if  isTouchDevice              Do something touchy       else             Can t touch this         If you don t use Modernizr  you can simply replace the Modernizr touch function above with   ontouchstart  in document documentElement   Also note that testing the user agent iemobile will give you broader range of detected Microsoft mobile devices than Windows Phone   Also see this SO question

You can t rely on navigator userAgent  not every device reveals its real OS  On my HTC for example  it depends on the settings   using mobile version  on off   On http   my clockodo com  we simply used screen width to detect small devices  Unfortunately  in some Android versions there s a bug with screen width  You can combine this way with the userAgent   if screen width  lt  500     navigator userAgent match  Android i      navigator userAgent match  webOS i      navigator userAgent match  iPhone i      navigator userAgent match  iPod i     alert  This is a mobile device

If you want to test the user agent  the correct way is to  test the user agent  i e  test navigator userAgent   If the user fakes this they are not due concern  If you test isUnix   you should not subsequently have to worry if the system is Unix   As a user changing userAgent is also fine  but you don t expect sites to render properly if you do   If you wish to provide support for Microsoft browsers you should ensure the first few characters of the content includes  and test every page you write   Bottom line    Always code to the standards  Then hack it until it works in the current version of IE  amp  don t expect it to look good  That s what GitHub does  and they just got given 100 million bucks

How about mobiledetect net   Other solutions seem too basic  This is a lightweight PHP class  It uses the User-Agent string combined with specific HTTP headers to detect the mobile environment  You can also benefit from Mobile Detect by using any of the 3rd party plugins available for  WordPress  Drupal  Joomla  Magento  etc

I would be suggesting to use following combo of strings  to check if device type being used   As per Mozilla documentation string Mobi is recommended  But  some of the old tablets doesn t return true if only Mobi is used  hence we should use Tablet string too   Similarly  for being on the safe side iPad and iPhone strings could also be used to check the device type   Most of the new devices would return true for Mobi string alone   if   Mobi Tablet iPad iPhone  test navigator userAgent            do something

It s not jQuery  but I found this  http   detectmobilebrowser com   It provides scripts to detect mobile browsers in several languages  one of which is JavaScript  That may help you with what you re looking for   However  since you are using jQuery  you might want to be aware of the jQuery support collection  It s a collection of properties for detecting the capabilities of the current browser  Documentation is here  http   api jquery com jQuery support   Since I don t know what exactly what you re trying to accomplish  I don t know which of these will be the most useful   All that being said  I think your best bet is to either redirect or write a different script to the output using a server-side language  if that is an option   Since you don t really know the capabilities of a mobile browser x  doing the detection  and alteration logic on the server side would be the most reliable method  Of course  all of that is a moot point if you can t use a server side language

For me small is beautiful so I m using this technique   In CSS file      Smartphones -----------     media only screen and  max-width  760px       some-element   display  none        In jQuery JavaScript file        document   ready function               var is mobile   false       if      some-element   css  display     none             is mobile   true                       now I can use is mobile to run javascript conditionally      if  is mobile    true              Conditional script here              My objective was to have my site  mobile-friendly   So I use CSS Media Queries do show hide elements depending on the screen size   For example  in my mobile version I don t want to activate the Facebook Like Box  because it loads all those profile images and stuff  And that s not good for mobile visitors  So  besides hiding the container element  I also do this inside the jQuery code block  above    if  is mobile         function d  s  id            var js  fjs   d getElementsByTagName s  0           if  d getElementById id   return          js   d createElement s   js id   id          js src      connect facebook net pt PT all js xfbml 1 amp appId 210731252294735           fjs parentNode insertBefore js  fjs         document   script    facebook-jssdk         You can see it in action at http   lisboaautentica com  I m still working on the the mobile version  so it s still not looking as it should  as of writing this   Update by dekin88  There is a JavaScript API built-in for detecting media  Rather than using the above solution simply use the following     function               let isMobile   window matchMedia  only screen and  max-width  760px    matches       if  isMobile              Conditional script here              Browser Supports  http   caniuse com  feat matchmedia  The advantage of this method is that it s not only simpler and shorter  but you can conditionally target different devices such as smartphones and tablets separately if necessary without having to add any dummy elements into the DOM

I tried some of the ways and then I decided to fill a list manually and do a simple JS check  And in the end the user has to confirm  Because some checks gave false positive or negative   var isMobile   false  if   Android webOS iPhone iPad iPod BlackBerry IEMobile Opera Mini Opera Mobile Kindle Windows Phone PSP AvantGo Atomic Web Browser Blazer Chrome Mobile Dolphin Dolfin Doris GO Browser Jasmine MicroB Mobile Firefox Mobile Safari Mobile Silk Motorola Internet Browser NetFront NineSky Nokia Web Browser Obigo Openwave Mobile Browser Palm Pre web browser Polaris PS Vita browser Puffin QQbrowser SEMC Browser Skyfire Tear TeaShark UC Browser uZard Web wOSBrowser Yandex Browser mobile i test navigator userAgent   amp  amp  confirm  Are you on a mobile device     isMobile   true    Now  if you want to use jQuery to set the CSS  you could do the following     document  ready function       if  isMobile     link type  text css     attr  href     mobile css          Since the borders between mobile and fixed devices become fluent and mobile browers are already powerful  checking width and user confirmation will probably be the best for the future  assuming that width in some cases will still be important   Because touches are already converted into mouse-ups and downs   And concerning the mobile movability  I suggest you to think about Yoav Barnea s idea   if typeof window orientation      undefined

Ya ll are doing way too much work   if  window screen availWidth  lt   425          do something     You can do this on page load through JS  No need to write long string lists to try and catch everything  Whoops  you missed one  Then you have to go back and change it add it  The more popular phone sizes are about 425 in width or less  in portrait mode   tablets are around 700 ish and anything bigger is likely a laptop  desktop  or other larger device  If you need mobile landscape mode  maybe you should be working in Swift or Android studio and not traditional web coding   Side note  This may not have been an available solution when it was posted but it works now

Editor s note  user agent detection is not a recommended technique for modern web apps  See the comments below this answer for confirmation of this fact  It is suggested to use one of the other answers using feature detection and or media queries   Instead of using jQuery you can use simple JavaScript to detect it  if   Android webOS iPhone iPad Mac Macintosh iPod BlackBerry IEMobile Opera Mini i test navigator userAgent          some code      Or you can combine them both to make it more accessible through jQuery      browser device     android webos iphone ipad ipod blackberry iemobile opera mini i test navigator userAgent toLowerCase       Now   browser will return  quot device quot  for all above devices Note    browser removed on jQuery v1 9 1  But you can use this by using jQuery migration plugin Code  A more thorough version  var isMobile   false    initiate as false    device detection if   android bb d  meego   mobile avantgo bada   blackberry blazer compal elaine fennec hiptop iemobile ip hone od  ipad iris kindle Android Silk lge  maemo midp mmp netfront opera m ob in i palm  os   phone p ixi re    plucker pocket psp series 4 6 0 symbian treo up   browser link  vodafone wap windows  ce phone  xda xiino i test navigator userAgent           1207 6310 6590 3gso 4thp 50 1-6 i 770s 802s a wa abac ac er oo s -  ai ko rn  al av ca co  amoi an ex ny yw  aptu ar ch go  as te us  attw au di  -m r  s   avan be ck ll nq  bi lb rd  bl ac az  br e v w bumb bw - n u  c55   capi ccwa cdm - cell chtm cldc cmd - co mp nd  craw da it ll ng  dbte dc -s devi dica dmob do c p o ds 12  -d  el 49 ai  em l2 ul  er ic k0  esl8 ez  4-7 0 os wa ze  fetc fly  -    g1 u g560 gene gf -5 g -mo go   w od  gr ad un  haie hcit hd - m p t  hei - hi pt ta  hp  i ip  hs -c ht c  -     a g p s t  tp  hu aw tc  i - 20 go ma  i230 iac    -     ibro idea ig01 ikom im1k inno ipaq iris ja t v a jbro jemu jigs kddi keji kgt       klon kpt  kwc - kyo c k  le no xi  lg  g    k l u  50 54  - a-w   libw lynx m1 -w m3ga m50   ma te ui xo  mc 01 21 ca  m -cr me rc ri  mi o8 oa ts  mmef mo 01 02 bi de do t  -   o v  zz  mt 50 p1 v   mwbp mywa n10 0-2  n20 2-3  n30 0 2  n50 0 2 5  n7 0 0 1  10  ne  c m  - on tf wf wg wt  nok 6 i  nzph o2im op ti wv  oran owg1 p800 pan a d t  pdxg pg 13  -  1-8  c   phil pire pl ay uc  pn -2 po ck rt se  prox psio pt -g qa -a qc 07 12 21 32 60  - 2-7  i -  qtek r380 r600 raks rim9 ro ve zo  s55   sa ge ma mm ms ny va  sc 01 h - oo p -  sdk   se c  - 0 1  47 mc nd ri  sgh - shar sie  - m  sk -0 sl 45 id  sm al ar b3 it t5  so ft ny  sp 01 h - v - v   sy 01 mb  t2 18 50  t6 00 10 18  ta gt lk  tcl - tdg - tel i m  tim - t -mo to pl sh  ts 70 m - m3 m5  tx -9 up   b g1 si  utst v400 v750 veri vi rg te  vk 40 5 0-3   -v  vm40 voda vulc vx 52 53 60 61 70 80 81 83 85 98  w3c  -    webc whit wi g  nc nw  wmlb wonu x700 yas - your zeto zte - i test navigator userAgent substr 0 4           isMobile   true

Crude  but sufficient for restricting loading larger resources such as video files on phones vs tablet desktop - simply look for small width or height to cover both orientations  Obviously  if the desktop browser has been resized the below could erroneously detect a phone  but that s fine   close enough for my use case   Why 480  bcs that s what looks about right based on the info I ve found re phone device dimensions   if document body clientWidth  lt  480    document body clientHeight  lt  480        this is a mobile device

If by a mobile device you understand a touchable one  then you can determine it by checking existence of touch handlers   let deviceType      ontouchstart  in window                       navigator maxTouchPoints  gt  0                       navigator msMaxTouchPoints  gt  0                        touchable     desktop     jQuery is not needed for it

I know this question has a lot of answers  but from what I saw nobody approaches the answer the way I would solve this   CSS uses width  Media Queries  to determine which styles applied to the web document baseed on width  Why not use width in the JavaScript   For instance in Bootstrap s  Mobile First  Media Queries  there exist 4 snap break points    Extra Small Devices are 768 pixels and under  Small Devices range from 768 to 991 pixels  Medium Devices range from 992 to 1199 pixels  Large Devices are 1200 pixels and up    We can use this to also solve our JavaScript issue as well   First we will create a function that gets the window size and returns a value that allows us to see what size device is viewing our application   var getBrowserWidth   function        if window innerWidth  lt  768              Extra Small Device         return  xs         else if window innerWidth  lt  991              Small Device         return  sm        else if window innerWidth  lt  1199              Medium Device         return  md        else              Large Device         return  lg             Now that we have the function set up  we can call it ans store the value   var device   getBrowserWidth      Your question was     I would like to run a different script if the browser is on a handheld device    Now that we have the device information all that is left is an if statement   if device      xs         Enter your script for handheld devices here      Here is an example on CodePen  http   codepen io jacob-king pen jWEeWG

If you re not particularly worried about small displays you could use width height detection  So that way if width is under a certain size  the mobile site is thrown up  It may not be the perfect way  but it will probably be the easiest to detect for multiple devices  You may need to put in a specific one for the iPhone 4  large resolution

You can also detect it like below    isIPhone   function        return   navigator platform indexOf  iPhone      -1      navigator platform indexOf  iPod      -1          isIPad   function         return  navigator platform indexOf  iPad      -1        isAndroidMobile    function        var ua   navigator userAgent toLowerCase        return ua indexOf  android    gt  -1  amp  amp  ua indexOf  mobile         isAndroidTablet    function        var ua   navigator userAgent toLowerCase        return ua indexOf  android    gt  -1  amp  amp    ua indexOf  mobile

According to Mozilla - Browser detection using the user agent      In summary  we recommend looking for the string    Mobi    anywhere in the User Agent to detect a mobile device    Like this   if   Mobi  test navigator userAgent            mobile      This will match all common mobile browser user agents  including mobile Mozilla  Safari  IE  Opera  Chrome  etc   Update for Android  EricL recommends testing for Android as a user agent also  as the Chrome user agent string for tablets does not include  Mobi   the phone versions do however    if   Mobi Android i test navigator userAgent            mobile

What you are doing by wanting to detect a mobile device is getting a little too close to a  browser sniffing  concept IMO  It would likely be much better to do some feature detection  Libraries like http   www modernizr com  can help with that   For example  where is the line between mobile and non-mobile  It gets more and more blurry every day

You could also use server side script and set javascript variables from it    Example in php  download http   code google com p php-mobile-detect  and then set javascript variables     lt script gt    set defaults var device type    desktop    lt  script gt    lt  php require once   Mobile Detect php     detect   new Mobile Detect      gt    lt script gt  device type   lt  php echo   detect- gt isMobile       detect- gt isTablet      tablet     mobile      desktop      gt    alert  device type    lt  script gt
