Opera Mini 4.4

Opera Mini 4 has been updated. The new release is Version 4.4  According to a post on the Opera Mini blog, there are no visible changes in this version. However the network code has be redesigned which “opens up new possibilities for your network operator to integrate services like free Opera Mini browsing to certain sites”. I kinda doubt that Boost will ever use that feature. There are also bug fixes including one for a problem that affected skins on some Samsung devices.

Opera Mini 4.4 is recomended for phones that aren’t powerful enough to run Opera 5+ well or at all.

    • It could be many things including:

      Your phone is out of internal storage memory
      Your operator is blocking downloads
      The apps you are trying to download are incompatible with the phone
      The phone is defective

      Based on what you have told me I have no idea what the cause is. Troubleshoot by doing things like deleting some apps to free space or using a different operator’s SIM or trying to different, smaller, simpler apps,

  17. How can I ensure positively that it is a SIGNED VERSION any other is just a waste of minutes, somjetimes even signe stuff won’t load (descritor error ,whatever that is) Help please Peter

    • Most apps on this site are unsigned. The only ones that are signed are a couple of Google Maps versions which are prominently labeled as being signed.

      The easiest way to tell if an app is signed is to open the .jad file with a text editor or Wordpad and look for lines starting with “MIDlet-Certificate” or “MIDlet-Jar-RSA-SHA” followed by a lot of gobbledygook which is the actual signature.

      Signed versions of Opera Mini can be found at http://mini.opera.com using your mobile browser. Scroll to the bottom of the page and click the “Code signing…” link to see the signed versions. If you have trouble finding them or want to download a signed version to your PC see: How to Download Opera Mini Signed Versions.

  19. hi i really hope u can help, im using a vodafone VF354 & its built in browser is opera mini 4.2 which needs updating as it dont work rite, but wen i try 2 download beta version its says downloads not supported. wot can i do??

    • I don’t know anything about that phone. But you generally can’t replace or update built-in apps. If Opera Mini got corrupted, a factory reset should fix it. Back up your your contacts, photos etc. before resetting as they will be deleted by the reset.

  20. Could you tell me which the simplest version for android is?

    • There’s really only one Opera Mini version for Android, Opera Mini 7.5. It runs well on almost all Android phones including low end amd really old ones

  21. My phone samsung galaxy y duos gt-s6102 is not listed in opera’s list……does that mean no opera mini for me???

    • No, it just means Opera hasn’t tested that phone. It will probaby work.

  22. How can i install opera 7 in my samsung GT-E2152 ??

  23. How can i install opera mini 7.1 on my mobile Qmobile E880?

    • You can usually only upload files that are on the memory card.

  25. How can i install this version on my samsung GT E3210

    • Open this page in the phone’s browser and click the JAD link.

  29. I need uc browse in 150 250 kb is there any

  34. i use opera mini 4.4 in my samsung GT E2222.But i cant download softwares or any other files using it bcz it says ‘error in fetching file’ .. y does it say so? plz provide a solution for me.

    • That’s a known issue with Opera Mini and some Samsungs. Until it’s fixed you need to download with the Nokia browser or the UC Browser.

  35. I can’t see the photos

    • In Opera Mini 4.4? Go to Menu > Tools > Settings and be sure “Load images” is checked. It’s checked and you still don’t see the images it’s because your phone doesn’t have enough Java heap memory. Changing Image quality to low will reduce the memory needed and may help.

  36. samsung ch@boostapps.comt222 how to install jar and jad

    • Open this page in the phone’s browser and click the JAD or JAR link.

  37. problem of installing (it give network problem)

  40. Every time I get on facebook thru OM 4.4 n try to upload a picture It won’t all it does shows me the files to chose from but after I do that nothing happens just keeps askin me to allow it but still it doesn’t work any ideas anyone?

  41. works pretty well on my i836

  42. for some strange reason i can not access Facebook thru opera anymore , dont know what happened it only says cant connect to server or sometimes just a blank screen saying error it was fine a day ago

  43. Sir,
    I cant access http://m.yahoo.com/ on Samsung Champ c3303K via Opera Mini 4.x
    But native browser, bolt, uc works fine with that site.
    Whats the problem!
    Yahoo says Unsupported Device!
    Also, I can access with Opera Mini 4.x enhanced by Vodafone!
    Can you please upload OM 4.x by Vodafone? (In my area, Vodafone network is unavailable and I reset my phone).

    • The problem sounds like a bug in Yahoo’s browser detection code. I suggest you contact Yahoo and also file an Opera bug report as Opera may have greater persuasive powers with Yahoo than you would.

      I’m not on Vodafone either so I have no way of obtaining the Vodafone enhanced browser.


    • That’s hardly wort SHOUTING about. But this might help: Solving Opera Mini Connection Problems

  44. Works great on my boost iden network motorola clutch i475, Thanks! The facebook app wouldn’t work, but opera mini comes with facebook preloaded in the bookmarks and soooo easy and sooo much faster than the program the phone came with. Thanks again! Surfing is a breeze now

  45. On my ancient i760 4.2 still the best(4.3 and 4.4 cause power cycle.)

  46. not a big change but i noticed with 4.3 some sites would not display pictures only empty boxes bt with the new 4.4 is fixed so thats cool, also they brouhgt back socket/http option like i said nothing big but still an upgrade can’t conplaint.

  47. So far so good on my I880. Thank you!!!

  48. Thanks again.

  49. I keep getting an “Invalid Descriptor” error message when I try 2 download. Any help? Thank you, Dennis

    • I think I found and fixed the problem. Try downloading again.

  50. It works just like the previous version with nothing new to brag about on my i465 .
    One of the bugs that drive me crazy that still has not been fixed is that hitting the back button messes up the mapping of the links of the previous page .
