Sony Ericsson Xperia X10i – First Experience

I have just got a new Xperia X10i for my wife. It’s with Virgin who use the Optus network. Optus apparently have better coverage than Three (who we have been using for 6.5 years) and Virgin offers the best deals – they have good phones on low monthly rates and do nice things like selling most phones unlocked (the Xperia is one that comes unlocked).

I chose the phone for use in system administration work. A large screen should be good for reading email and running a ssh client. Hopefully I will be able to use the phone’s Wifi to provide mobile net access to a laptop for any problem that can’t be solved on a tiny screen. My wife doesn’t do much sysadmin work nowadays, but it’ll save some effort if we can both use the same model of phone. Also according to Amobil.no the Xperia X10 is the second best phone for camera-phone functionality [1], and my wife would really like to take some good pictures with her phone (she loves the LG U990 Viewty that she has right now).

Screen

One major reason for choosing this phone is that it has the biggest and highest resolution of any phone that doesn’t cost a huge amount of money. It does well in this regard, the screen is very good to look at. However it is apparently not particularly sensitive and we still have the protective cover on the screen which makes the swipe to unlock operation quite difficult. My wife generally likes to keep the protective plastic on such screens for a while to prevent damage, but she may take this off sooner than on other devices.

Sony Foolishness

One reason that this phone is cheaper than any other phone with similar specs is that it’s made by Sony. Sony won’t provide updates to Android 2.2 or better and they have their own stupid applications installed in an intrusive manner. The main screen of the phone has a large icon for the Sony Timescape program. If you choose a background image of a person’s face then the Timescape logo is in the ideal location to obscure the person’s eyes. Generally it’s not desired to have the person in your phone background look like Zorro. Fortunately you can delete icons from the home screen, you just have to press and hold the icon until a trash-can appears at the bottom of the screen and then drag it to the trash.

Phone Book

The core phone functionality is fairly important for a mobile phone. But it seems that every modern phone has some serious failings in this regard. The Xperia comes with a phone book that is reasonably good for managing contacts and partially coalesces multiple entries with the same name – which is convenient as I somehow managed to import 3 copies of each entry in my wife’s phone book. The down-side is that the multiple entries are still stored, so when it comes time to update someone’s phone number my wife will have to separate the entries and then delete all but one of them, adding probably a minute of effort for each one. With 60 phone book entries that’s probably an hour of wasted time during the course of her phone use.

They really should do a time based analysis of phone use and optimise the UI for efficiently performing common tasks. I think that an ideal design would start off by asking the user to rate the importance of phone functionality, camera, facebook, twitter, etc and then give a UI that matches the important tasks. A device that has 384M of RAM, 1G of built-in Flash storage, and an 8G micro-SD card (which Virgin provided with the phone) should be able to offer a selection of UIs.

Camera

The configuration for the camera allows some settings to be changed easily and others have to be changed through the “advanced” settings which requires one more button press and a few extra taps on the screen. One real stupidity is to have the phone light be in the advanced settings, so if the room happens to be a little darker than expected you suddenly need to go to a lot of extra effort to turn on the light.

Finally it would be really good to be able to take a quick picture. I would like to be able to be able to press a combination of buttons and have it immediately take a picture regardless of what had been running before. Not press the main menu button, the camera icon (which I made a link from the home screen), wait a second for it to load, and then press the shutter button. Ideally I would like to press a combination of hardware buttons to have it immediately take a picture even when the screen is locked. I don’t want to wait for the screen unlock process, sometimes the perfect shot is only available for a second.

Wifi

It doesn’t support ad-hoc networks. This is really annoying for me as I don’t own an access point – and I don’t plan to buy one just for a phone. My laptop (Thinkpad T61 with Intel Corporation PRO/Wireless 3945ABG [Golan]) doesn’t seem to support running as an access point, and my EeePC 701 with an Atheros AR5001 has the same problem, here is the error message:

# iwconfig wlan0 mode master essid x
Error for wireless request “Set Mode” (8B06) :
SET failed on device wlan0 ; Invalid argument.

I have a cheap Realtec USB Wifi device that claims to support being an access point but just fails when I try it. So presumably it doesn’t really support it but the driver is buggy.

It seems that I may need to put a custom Android installation on it to get ad-hoc working.

Also it’s apparently necessary to root the Xperia to get Wifi tethering to work for providing net access to a laptop. So I guess I’ll hacking it soon.

Internet Access

The Virgin web site couldn’t help me set up the Internet access because I ported a phone number from another Telco. I had to use the phone number supplied by Virgin to login to their web site and the site then wanted to “sent” (probably SMS) the settings to my phone, but of course it couldn’t SMS to that number as I’ve got the Three number active. Presumably they were expecting that customers would setup Internet access before porting their old number.

I phoned the Virgin tech support and used the settings they suggested, but it didn’t work. Then I took the phone to a Virgin store and it started working after they rebooted it with no changes to settings. Just like Windows used to be. :(

Email Access – Default App

The email setup defaults to port 143 IMAP access, so even when a mail server provides access on port 993 for IMAPS and on port 995 for POP3S probably most users will not use any encryption because their phone doesn’t default to it. Also one annoying feature is that when I gave it the email address “test@coker.com.au” it decided to use “test” as the user-name for IMAP by default. It seems that a very large portion of the active email accounts nowadays are on systems that handle multiple domains and thus require the domain name in authentication, and a large portion of the remainder accept domain names even when they aren’t required. Besides it’s a lot easier to delete a domain name when it’s not needed than to type it in when it is.

The default hostname for sending and receiving mail is the domain name, if the MUA configuration program had checked the MX record it would have known that smtp.sws.net.au is a better default choice for the mail server. I’ve now started the practice of creating a CNAME entry named “m” in every domain I run, so when someone is setting up a mobile phone they just have to add “m.” to the start of the default hostname to use for sending and receiving mail. By doing this I can probably save an average user at least 30 seconds of typing, which is particularly important if I happen to be talking them through the process!

The MUA uses IMAP commands to load the text of the message without attachments and then loads attachments on demand, this will be handy for when people attach unreasonably large files. With IMAP caching and partial loads the core functionality seems OK, and some quick tests of standard but not commonly used IMAP functions such as noticing that mail has been deleted by another client seemed to work well. The performance of loading a new mailbox with 369 message was quite poor, I’m not sure how much of this is due to the network connection and how much is due to the client implementation. This is a real concern for me as I typically have about 7,000 messages in my IMAP account and 3,000 unread messages most of which are in two folders.

Another problem is the fact that there seems to be no way of searching in the list of messages, sorting/grouping by subject or sender, or showing unread messages. This makes the Xperia unsuitable for the task of reading mailing lists when on public transport. I would really like to be able to sort through a folder of mailing-list mail, delete messages that I don’t need to keep and flag ones that need attention when I have the resources of a desktop system when I’m on a tram or in other situations where a laptop can be inconvenient.

One undeniable bug I discovered (as opposed to the missing features I listed) is that when a message has a line with a URL followed by many spaces it won’t load correctly in the web browser, the spaces will be treated as part of the URL. I’ve changed the default signature in my email to have a description followed by a URL to avoid triggering this bug. Presumably other Android phones are bug for bug compatible. :(

Moxier Mail

There is a complete set of email and calendaring applications preloaded from Moxier.com. The Moxier mail client uses company.com as an example domain name (they should use example.com – does no-one read the RFCs?). It’s nice that they verify the SSL certificate and display the details when it’s not signed.

Unfortunately Moxier doesn’t support anything other than Exchange, and I can’t delete it either as it’s part of the base set of applications from Sony.

SMS

The SMS application is supposedly “conversation” based. This doesn’t seem like a benefit to me, it’s a pity that there is no option to make it act more like every other SMS implementation I’ve used over the last 12 years.

Battery

The battery is described as having a capacity of 1500mAh, for comparison a AA rechargeable batteries have capacities ranging from 1800mAh to 2800mAh. My first mobile phone had a rechargeable battery that took the same space as 4*AA batteries and the phone was designed to run on AA batteries if the main battery wasn’t charged. I would like to have an Android phone that had a battery pack of similar size to at least 2*AA batteries, and 4*AA would be OK too.

The Xperia battery was reported as being half discharged after playing with the phone for less than an hour. Basically when doing anything with the phone that is remotely intensive I need to have it plugged in. Unless of course I’m using one of the star-chart applications…

Lights

There are two white leds in the gaps between the keys for Settings, Main-Menu, and Back on the front. They are quite bright and annoying to look into at night.

SSH

SSH was one of the reasons for getting an Android phone, but it was one of the last things I worked on because everything else was so much fun. I’m currently using ConnectBot, it supports storing ssh host keys, generating a key-pair from random screen touches, locking and unlocking the key-pair (with a pass-phrase) and pasting the public key to an open window. All the basic functions just work although it’s rather inconvenient to enter the CTRL keys.

The next thing to investigate is a small and light Bluetooth keyboard. Using an external hardware keyboard will save me from the pain of entering CTRL keys (which is even worse than the pain of entering passwords that contain digits and mixed case). It will also allow me to type a lot faster and use the entire screen for the ssh session.

Current Bug Summary

Wifi doesn’t do ad-hoc mode or tethering.

MUA doesn’t correctly handle URLs in messages if many spaces follow the URL and is also unsuitable for mailing list mail.

Sometimes requires a reboot to make Internet access settings take affect.

Camera light can’t be easily turned on and off.

This isn’t too bad.

Conclusion

Most things do what I want. Once I get a MUA working with all my email, Wifi doing what I want, and a Bluetooth keyboard it’ll be a fairly ideal mobile sysadmin terminal. I’ll probably order one for myself this weekend.

    See what the internet cache is. On my Desire fitted with a 16GB micro SD I can dial the cache all the way up to…. six MEGA bytes??? wtf?

  • You should take a look at http://wireless.kernel.org/en/users/Documentation/hostapd. “iwconfig” is deprecated and AP support is not supported with iwconfig on _any_ modern wireless card.

  • Forgot to mention — Intel 3945 doesn’t support AP, but the Atheros card should.

  • Philipp Kern

    Please blog about your choice of bluetooth keyboards that actually work with Android. Thanks. :)

  • For mail, try K-9 (or K9?). A bit like mutt for android

  • etbe

    Brendan: Thanks, I’ll check that out.
    Johannes: Thanks, I’m working on that now.
    Phillip: What makes you say that? Should I be expecting difficulty in this regard?
    Karl: Thanks for the suggestion, I’m sending that to the phone now. It’s nice that the Android market app allows me to use my PC to push applications to the phone (my wife has the phone and is on the other side of Melbourne at the moment).
    Karl: Thanks, I’m installing that now. I’m also installing some Nagios clients.

    One thing to note about the Android app market is that their search facility is lacking. The above sites have been useful for me in the past for searching the Android Market.

    Ad-hoc mode: Yes, this seems to be a major problem with Android. I just returned a very nice Android tablet, an Archos 701, because ad-hoc support is crucial for my use of the device. I stay with a netbook running Debian until Google solves the problem.

    Hi

    I too have just bought the Xperia 10i – I love everything about this phone – although i don’t use it for business purposes – its basically used for a phone camera and facebook. My kids love the apps – games generally. However i agree that the camera is not the best – at 8.1 megapixels i was expecting something at least as good as my LG Renoir, which is 8 megapixel – with a proper flash and takes awesome pics. The light on the Xperia 10i is the worst thing ever and the focus or lack of is most annoying – i certainly have down graded when it comes to the Camera on this smart phone…. quite dissappointing really

    Tim: My Xperia phones run Android 2.1 and don’t seem vulnerable to that. Also I’m not relying on the lock pattern for anything serious. For my usage patterns the greatest risk of theft is of someone snatching it while it’s in use so I have to assume that it will be stolen while unlocked.

    Martin: I’m using Easy Tether for my tethering as described in the above post. It works well enough, also Sony have announced that they will release Android 2.3 for the Xperia X10.

    Linda: My LG U990 Viewty compares very well to my Xperia X10 for photos and videos, it’s an issue of lens size, the Viewty has a really large lens by phone standards – presumably the Renoir is even better (but it was too expensive for me). Yes the use of the light is poor, my main complaint about that is the inability to rapidly switch it on and off while preparing to take a photo – things like that should be a single touch.

    http://etbe.coker.com.au/2010/11/26/quality-of-cameras-in-phones/

    That said, the Xperia X10 did quite well on the Norwegian survey and they published the pictures to prove it. It’s unfortunate that cameras in phones just suck. I wrote the above post about this issue, in summary phones are just too thin, a thicker phone with a greater focal length and a wider lens would give much better pictures.

    The size of phones forces trade-offs for every phone, so for every phone there will be at least one objective measure by which it sucks.
