Cubot X12 — Dual SIM Use

I have written before about this great value phone:

A Cheap Android Phone
Practical Stuff on the Cubot X12

Its selling points are 4G/LTE operation, and Dual SIM capability. I’ve already found that 4G works and works well on GiffGaff. I am currently in Bulgaria and I have had a chance to put Dual SIM operation to the test.

I rooted a phone! And it works!

Everything described here is risky. You can render your phone useless by rooting it or installing a third-party operating system, and you do this entirely at your own risk.

Over the last couple of years, I’ve read about “rooting” an Android mobile phone, but was scared of being left with a brick. However, my Samsung Galaxy S3 was hardly worth saving, once I’d got my new phone. The USB port was buggered, and everything on it took place at snail’s pace.

I did a factory reset, but there was still no way of removing all the bloatware. So although I now had a phone that would work, there were few apps on it that I would want to use. Continue reading →

Practical Stuff on the Cubot X12

See previous article: A Cheap Android Phone

Update 21 Jan 2018: Apps keep getting bigger, and after a while, the 1Gb RAM and 8Gb ROM can no longer cope. So I found a new use for the phone, as a Bluetooth Jukebox. The InfraRed feature on the phone made it even better.

On my old Samsung Galaxy S3 phone, I used to use a program launcher called Solo, rather than the one built in. It’s a great way to build your Home screen on an Android phone. Since switching to the X12, with a lot of problems resolved regarding speed and lock-ups, I started getting more picky about the “little things”. One of which was the tendency for the Weather Clock and Calendar Applets to freeze from time to time, necessitating a reboot.

One of the reasons I found, on the internet, for this was that they are being crashed by over-enthusiastic “memory cleaners”, of which Solo has one built in. I tried a number of other Launchers, and generally they had the same problem. And they could not do what Solo did, to vary the screen grid (I think it looks better with 5 rows and 4 columns, than the standard 4×4). Continue reading →

A Cheap Android Phone

One of the things that enables the British people to ripped off by Big Business, is their mistaken belief that the more you pay, the better product you will get. This is illustrated by a couple I used to know. The man of the house could tell Heinz Tomato Ketchup apart from rival brands and supermarket brands. He could taste the difference! However when the lady of the house craftily filled an empty Heinz bottle with Aldi own-brand ketchup, the Aldi sauce, when served from a Heinz bottle, tasted exactly like Heinz. Indeed, he could distinguish the flavours of Aldi ketchup from a Heinz bottle and Aldi ketchup from an Aldi bottle, the first being delicious and the latter being rubbish. Continue reading →

A Cheap Linux Laptop — Take 2

You may have seen my previous article “A Cheap Linux Laptop“. Well this is a rewrite. I have changed several things since I wrote the original article, and I think it would be better to start over. The major changes are: (a) lessons learnt, (b) I installed a Solid State Drive, and (c) I used the LXDE desktop instead of XFCE. [I am now back with XFCE.]

Back in April, I bought a laptop, a Lenovo B50-45, for £160 brand new. It has a 15.6in screen, and is big enough to include a numeric keypad! Surely it can’t be any good for that money!! I got it from Ebuyer, who don’t stock it any more. Six months down the road, the model is selling at a higher price via other suppliers. There are a number of models in the B50 series, and I imagine that they would prove to be similar. Continue reading →

Facebook, and the White Screen

I don’t know whether this has ever happened to anyone else. This is what happens if I attempt to log into Facebook in my account:

Yep, that’s it a totally white screen.

This is been going on over a day now. Just as a second test, what do you think might happen if I log in again, but using “” instead of “www” at the start of the address? Well, I do get to see a bit more:

Libre Office 5.0 Released!

One of the things I can never get my head around, is the love affair computer users have with Microsoft Word and Microsoft Office. It’s as if it is an essential piece of software. Because of its cost, people will risk being caught breaking the law with illegal copies. And yet, it’s nothing special, and there are other wordprocessors and office-suites out there which do the job just as well, and in some cases better, at a fraction of the cost.

One such office suite is LibreOffice, and it has the major advantage of being free! And the recent update to version 5.0 marks a milestone in the development of this excellent piece of software. A question could reasonably be asked, how can software be any good if it’s free? Won’t the best software writers go and work for someone who pays them? Well I’ve written stuff before about this. There are different types of free, and it’s as well to know how the difference between free as in no charge, and free as in Open Source. Free programs like Libre Office, as well as Firefox, Google Chrome, and many others, have versions compiled to run on Windows, Linux and Macs, and could be the right things to try, to see if Linux would be a good operating system for you!

A cheap Linux laptop

A few weeks ago, I bought a laptop, a Lenovo B50-45, for £160 brand new. It has a 15.6in screen, and is big enough to include a numeric keypad! Surely it can’t be any good for that money!! I got it from Ebuyer, though at the time of writing they are temporarily out of stock, but with the promise of more to come. But still for that same price.

Reviews were surprisingly good, but I tend to look at the worst ones first, and they complained of a lack of speed, that you were often waiting for the computer to catch up. However, it’s running Windows 8. My intention was always to use PCLinuxOS 64-bit XFCE edition. So let’s see how the hardware stacks up.


  • AMD Dual Core E1-6010 1.35GHz processor ought to cope with Linux, comfortably.
  • It has a single chip of 4Gb RAM, but has two SODIMM DDR3 slots, and can take a total of 16Gb RAM. A second 4Gb in the other slot could take it up to 8Gb. But in any case, you’d think that 4Gb would run Linux OK.
  • 5400rpm Hard Drive, 320Gb. Hmmm, could be a problem. The question is how get-at-able is it, could it be changed for a solid state drive?
  • Radeon R2 graphics which I know little about.

Brother Printer/Scanners, my experience using one with Linux

I have never participated in Black Friday before. I certainly didn’t fancy the the crushes I saw in the news. But when I saw an offer for a Brother MFC-J5320DW printer/scanner (RRP £200, usual on-line price £150) for £110 online, my only thought was: will it work in Linux? Well I checked the Brother site, and it showed downloadable drivers for the scanner. I assumed that the printer would “just work” as they often do in Linux. So I ordered it.

It arrived the following Tuesday morning. It’s a monster, but width-wise, it’s not significantly wider than my HP Deskjet, so its actual footprint on the side table next to my workstation is no bigger. And it prints A3!

Free Software: Different types of free!

You are going to the home of a very generous couple. Let’s call them Rodney and Cassandra. Now Rodney is famous for brewing his own beer and it’s delicious. Cassandra makes a lovely soup. The flavour is incredible. You can imagine they are very popular. You and your friends have a lovely evening. At the end of the night, you ask Rodney if you can take home some of his beer. He agrees, but imposes some conditions.

  1. You can have the beer free, but for personal use only. You may not pass it on or sell it to anyone.
  2. You may not try to analyse or reverse engineer the beer to discover the formula in any way.
  3. You accept that the recipe for the beer is the property of Rodney.
