Opera Mini Tips and Tricks

If you've been reading this blog for a while I'm sure you've noticed that I'm a big fan of Opera Mini, it's my favorite mobile browser. The first thing I do when I get a new phone is install Opera Mini on it. It seems like a lot of other people like Mini too.  GetJar reports that it's the most downloaded Java ME application of all time.  According to Opera, Mini has 21 million active users, more than the total number of iPhones or Nokia N95s sold to date.

Although Opera Mini is a great browser it's not always easy to install and configure.  There are also a lot of neat features that aren't obvious including some undocumented ones.  This is the first in a planned series of "Opera Mini Tips and Tricks" posts on Wap Review.  I recommend reading Opera's own official  Opera Mini FAQ and user forum first.  However, no one document can cover every potential issue or question.  I hope these posts will serve as a helpful addition to the official docs.

I'm going to start at the beginning, installing Opera Mini.  Opera's download sites, both the mobile and PC versions seem to confuse many users so here's a little FAQ on installing Opera Mini

Q. What are the requirements for running Opera Mini?

1) You need a phone that is capable of running Java ME Applications. About 90% of phones sold worldwide are. This is not true in the US unfortunately.  As the majority of my readers are in the US here is a breakdown of the situation.

If your carrier is Sprint (CDMA only), AT&T, STi or a regional GSM carrier like i Wireless or Einstein you should be able to run Opera Mini.

If you have a BlackBerry, Palm OS or Windows Mobile phone on any carrier you should be able to run Opera Mini.  Palm and most Windows mobile users will need to install a Java JVM run-time.

For help in finding and installing the best Windows Mobile JVM (there are several), the best source of information is Werner Ruotsalainen's "(Java) MIDlet Bible"

There is only one JVM for Palm OS but it has been discontinued and isn't very easy to find.  You can get the Palm JVM from MyTreo.net. You do have register to download, but it's free and MyTreo is a great site for Palm users. The Palm JVM is rather buggy.  It tends to crash a lot running Opera Mini.  You can minimize crashes by going to Prefs on the Palm, scrolling down to Other and choosing IBM Java VM, and setting the following:

  • Memory Maximum: 4-32 MB (32MB seems to work for most models but if you still get crashes try lowering it).
  • Maximum Java Thread Stack Size: 32 Kb.
  • Check 'Use Double Buffering'.
  • Check 'Use high resolution coordinates'.

Verizon, US Cellular, Alltel, and regional CDMA carrier  customers who don't have a BlackBerry, Palm or Windows Mobile phone are mostly out of luck as these carriers have blocked Opera Mini in one way or another.  There are exceptions so it doesn't hurt to try.  I'll get into these exceptions and the generally complex work-arounds involved in a latter installment of this series.

Most T-Mobile USA branded phones are Java capable but T-Mobile has crippled the JVM to prevent users from running Opera Mini and other 3rd party Java applications that connect to the Internet.  The exceptions again are BlackBerry, Palm and Windows Mobile and also unbranded GSM phones purchased from Nokia, Sony-Ericsson, etc.

Virgin Mobile phones have Java but Virgin has crippled it to make installing Opera Mini impossible on most phones.  Their are exceptions for a few handsets that require some advanced hackery to get it working.

Most Cricket and MetroPCS phones don't have Java and there is no way to add it,  but there are a few models that do.  Check you phone's manual.

Boost Mobile and Sprint/Nextel iDen users can run Opera Mini but must install it using a PC and data cable.  Instructions are on the Opera Mini Blog.  They are a couple of years old but still work.  The instructions refer to Mini 3.1 but 4.2 works very well on iDen phones.

2) You will need a data plan. I recommend an unlimited data plan if at all possible.  All the US carriers offer unlimited plans to postpaid customers for between $10 and $30 per month. Sprint CDMA and AT&T customers do have pay per use data enabled by default, however it is very expensive, $10/MB. At that price it is not hard to run up a thousand dollar bill in a month! - You have been warned!

The mobile data picture for prepaid users in the US is not pretty.  T-Mobile doesn't offer data at all on prepaid, AT&T does but it's overpriced at between $2-$10/MB. The only US carriers offering reasonably priced prepaid data in the US who also have phones that can run Opera Mini are Sprint's Boost Mobile and Sprint MVNO STi Mobile.  Boost has unlimited data for $10.50/month. It's a little slow but has no cap.  STi charges $9/month for "unlimited" data which has an undocumented cap of 12/MB per week.  If you exceed the cap, STi will warn you the first time and irrevocably terminate your data access if you exceed it again.

Q. How do you install Opera Mini?

You can download Opera Mini from many sites but the best way is to get it directly from Opera. If possible download and install Opera Mini by using your phone's built in browser to go to mini.opera.com. By downloading from Opera you're sure of getting an unaltered copy of the latest version. If you use your phone's browser Opera will deliver the best version for your phone and the download will include an icon that is the optimal size. The image above shows what what most users will see when they visit mini.opera.com with a phone. The "We recommend this version" indicates that Opera has successfully tested Mini on your phone model and determined which of the six versions of Opera Mini is best for it

Opera has tested hundreds of phones but there are still some that it hasn't.  So you may also see the the message, "Your phone model could not be detected..." (2nd image.).  This message seems to confuse a lot of people who think it means that there is no version of Opera Mini for their phones.  In reality, Opera Mini is a generic application that works on most phones, there are several versions but they are not specific to particular phone models.  All this message really means is "Opera hasn't tested Mini on your phone" If you see this screen go ahead and download Opera Mini, it will probably work and won't hurt your phone if it doesn't.

Q. What versions of Opera Mini are available - there are six current version of Opera Mini.

Mini 3.1.2 "low memory" - which uses the older  Java MIDP1 standard . It's about 60 KB in size.  Some old or very low end phones, including all of STi Mobile's,  can only use this version.

Mini 3.1.2 "high memory" - which is built to work with phones supporting the current MIDP2 Java standard.  It's about 100 KB and adds support for skins, photo uploading, Speed Dial and full screen mode.

Mini 4.2 "multiple certificates" The newest and best version of Opera Mini. Additional features include full upload and download capabilities, page search, bookmark backup and restore and a "keyhole" browsing mode which displays pages as they look on PC browsers. It's about 100 KB in size and is digitally signed with both Verisign and Thwarte certificates.  Signing gives users the option to disable security prompts that occur when connecting to the Internet and uploading or downloading.  Some phones require apps to signed to be able to install, connect or access the file system to upload and download.  The multiple certificates mean it should work on phones that except either Verisign or Thwarte certificates.

Mini 4.2 "Thawte cerificate" -  This is the same as the multiple certicate one but is only signed with the Thawte certificate. A few phones can't handle multiple certificates but will acccept the Thawte one.

Mini 4.2 "Verisign certificate". Same as above but with a Verisgn certicate.

Mini 4.2 "unsigned" -  It's not digitally signed so it will work with some phones, including Motorolas, BlackBerries and Sprint handsets, that will reject applications signed with the industry standard Verisign and Thwarte certificates.

Q. I don't see all these versions on mini.opera.com. Where are they? - Opera tries to guide you to the version that is most likely to work well on your phone.  If you want to experiment, all the other versions are available on mini.opera.com.

If the download is defaulting to one of the 4.2 versions, scroll down and click the link that says "If this version fails to install or you would like to install a previous version, please click here." This will bring up a screen (3rd image) offering the other 4.2 versions and a link labeled "Try the old Opera Mini 3" which leads to the the 3.1.2 download choices.  The 3.1.2 download screen has a link to the 4.2 versions as well.

I hope these tips help you get started with Opera Mini.  Look for more tips here soon.

    I've seen two different scenarios where Opera Mini doesn't display all the images on a page

    1.On large pages with many images, when Opera Mini thinks it' starting to run out of available memory it will display gray boxes in the place of images. You can at least partially eliminate this by choosing a lower image quality such as medium or low instead of high on the settings page.

    As you mention, UCWEB seems to be able to display all the images on pages where Opera Mini shows gray boxes, possibly Opera Mini's memory management is less efficient somehow.

    2. There is also a bug where in mobile view, Opera Mini will not display images that are less than about 30px wide. If you turn off mobile view these images will appear.
  14. I have followed your posts on Opera Mini as well as other mobile browsers and found them quite useful. The way you presented for creating bookmarklets for Opera Mini was particularly of value. Thanks a lot. We are looking forward to more info from you.

    Currently my biggest problem with Opera Mini 4.2 is that it leaves out some images on image-rich web pages like Wikipedia pages on countries. Do you know any way to circumvent this? My phone is a Nokia N70, which handles any page very well with UCWEB Symbian but I like the page rendering of Opera Mini better. Also, I can get to the URL of a saved web page on Opera Mini by opening it and trying to bookmark it so that I can link to it in my blog. With UCWEB, saved pages have to be reloaded if you want to copy the URL, which I find a bit annoying.
