How to root your Android phone

May 03, 2015 — BarryK
Well, this is how I did it for the Mlais M52 Red Note, with KitKat 4.4.4.

This forum has ongoing information about the M52: has advice to use Kingoroot to root the phone. Unfortunately, I found that does not work.

Instead, I found instructions to use iRoot, that does work:

Unfortunately, the Internet has many places to download iRoot for Windows, and the one I first installed also installed heaps of crap. Beware sites that seem to be offering later versions, and look like proper official sites.

This seems to be the author's site, and where I got it on the second go:

A Windows driver is also required, that you get from here:
Scroll down, you will see this link to the file to download:

The first link has instructions, but this is what I did:

1. I installed the Windows Universal ADB driver, without the phone connected.
2. I plugged in the phone, via USB cable, then installed iRoot.
3. I think there was a button to click to perform the root operation. Note, it is important that your PC have a working Internet connection at this time, as iRoot automatically downloads scripts for the type of phone that it has detected. Also, watch the phone screen, you might have to approve an installation.
4. That's it, done. iRoot should report success. It does leave behind some apps on the phone -- I was uncertain just what was installed, I think an "su" program, and something else in Chinese -- I deleted the latter.

I now seem to have three "su" management apps on my phone, Kangouser, SuperSU and Superuser, the first installed as a system app, don't know how to get rid of it.

Anyway, a check with Root Checker verified my phone is rooted, and Root Explorer is able to copy files to/from my external USB Flash stick.


Mlais M52 first impressions

April 24, 2015 — BarryK
I bought two cheap smartphones from China. I have both of them in front of me, and will do a mini comparison. For now, focussing on the Mlais M52, what are my first impressions?

I reported on ordering the M52 here:

OK, so it has a very fast octa-core 64-bit CPU, does 3G and 4G (with all the frequencies that I need in Australia), 5.5 inch screen, removable battery, and most importantly for me, dual-sim slots plus a sd-card slot.

False advertising
There are a couple of negative comments that I have to get out of the way. Firstly, Mlais have advertised the cameras as 13 megapixel at back, 8 at front. However, it has been reported that they are only 8 and 5.
Another thing is the battery -- this is advertised as 3200mah. However, based upon its weight (47g) and volume, I would say it is about 2600mah.

Other reviewers have commented on poor camera performance and likely over-stated battery capacity. OK, battery capacities are overstated by every manufacturer anyway, but Mlais are taking lying to a new level.

Most unfortunate, the company is lying, to make the product look better than it is. If I had known this beforehand, I would not have purchased an Mlais, as a matter of principle.

But, I do have one, so what do I think of the phone? Actually, it is a very nice phone, very well made.

This is what I wanted. Here in Australia, I get the best deal with two sims, one for phone calls and texting, the other for data. I already reported on a data sim with 12GB per month, AU$40 (US$29), no excess fees, from Virgin Mobile:

You just cannot get that much data from a phone/text/data plan, unless you pay a lot lot more.

For phone/text, there are excellent cheap pay-as-you-go prepaid plans. I looked for one with long expiry. I settled on Amaysim "as you go" prepaid plan. I have this thing, reluctant to give out my credit card details over the Internet -- well, Amaysim have retail outlets all over the place, and I just paid cash, $2 for a sim, $10 credit, and I am good for 90 days. Calls are 12c per minute, texts 12c each.

Note, I don't talk for long on the phone, so the pay-per-minute is ok for me. If you are a chatterbox, Optus have a prepaid pay-as-you-go sim that has 180 day expiry, $1 fee per-day for a calls or text, and if the calls go over 30 minutes it becomes $1.50 for unlimited calls. if you don't make any calls/texts in the day, no charge.

I use the data-sim as my only Internet access, both on-the-go and at home. At home, I turn on tethering, also known as wi-fi hot-spot, and access the Internet from my laptop.

It works well, I have not encountered any problem with the two sims, no clashes.

Weight, size
This is weird. The other phone I purchased is a Elephone P6000, with 5 inch screen. A smaller phone, lighter than the Mlais, yet in my hand it feels heavier.
The Malis M52 weighs 172g (with battery), the Elephone weighs 167g. Without batteries, they are 125g and 117g.

Weird, the feeling of the Elephone is that it is heavier. It is slightly thicker, but only about 1mm. Smaller dimensions. Not only does the Mlais feel lighter, it feels better in my hand, despite being bigger -- maybe because it is slightly thinner and the back slightly more curved.

They are both 720p screens, and I have to say, this is enough. The 1440p screens on premium phones these days is just ridiculous. I am hard-pressed to see any pixelation on these screens, 720p looks good. OK, I might be persuaded to go up to 1080p to banish pixelation totally if squinting up close to the screen, but beyond that is just an unnecessary drain on the battery, as well as dragging down performance.

The slightly bigger screen is nicer, so the Mlais wins there. Also, the screen is brighter and has higher contrast than the Elephone -- seeing them side-by-side, the difference is quite striking. Playing with brightness levels does not help, the Elephone is inferior.
With the Mlais, whites are whiter, blacks are blacker, colours are richer.

Both phones have wider bezels than I expect of a modern phone. The Mlais excessively so. We already have a bigger screen, and the wide bezels make for a much bigger phone than I would like. However, as already stated, the thinness, 8.9mm and curved back make it a nice fit in my hand.

They both have pretty much stock Android, the Mlais has 4.4.4, the Elephone has 5.0 (Lollipop). Both have external capacitive buttons on the "chin", which I very much prefer, however, I am not accustomed to the change in functionality of those buttons with Lollipop.

Mlais have released Lollipop, which I may upgrade to sometime. However online reports are don't do it, as it is buggy. So, I will wait. Android 4.4.4 on the Mlais is a 32-bit operating system, so an upgrade to Lolliop will bring true 64-bit performance -- yet, the current OS is very fast.

Elephone seem to be taking the lead here, with a Windows utility for flashing various flavours of Android onto their phones. This ease of flashing is something that I am interested in.

I will report some more, but for now, I can draw some conclusions. Neither of these phones is ideal for me, but I have to remember that they are cheap.
The slightly smaller phone is easier to carry in a pants pocket, though weights are similar. But, it is the screen that decides it for me. The brighter and higher-contrast screen of the Mlais is so much nicer to look at.

So, despite my misgivings about their false advertising, I like the Mlais and for now this is the phone that I am carrying around. For now, anyway. If another phone comes along with same specs but smaller bezels and hopefully lighter weight, oh and a better camera, I will be tempted.

I should add a little post-note. I based my decision to buy the Mlais on a glowing review at Although the reviewer did not expose the false claim of 13mp, the reviewer did identify that camera performance is poor. The reviewer also raised doubt about the battery capacity. See their review:


Mlais M52 smartphone

April 15, 2015 — BarryK
I posted recently about a data sim with 12GB per month for only AU$40 per month (about US$32), no contract, no extra surprise charges:

In that post, I stated that I want a 4G phone, so I have now ordered one. Dual-sim, plus sd-card. It is model M52, made by Mlais, a Chinese company:

It is a bargain-basement price, with a very fast 64-bit processor. Here is a review:

I ordered it from, for an all-up price of AU$224, even though I could have got it a tad cheaper elsewhere. The "aud" prefix on the URL has expedited courier delivery to Australia, quite fast:

I specifically wanted dual-sim plus sd-card. I have a low-cost long-term prepaid phone/text sim, plus my new 12GB data sim -- this combination is incredible. It is suitable as my only Internet account, I run the phone as a wifi hot-spot at home.

The M52 does have some weaknesses, apparently the battery life is not so good (but it is removable, and I have ordered a spare), but the cause of that is not yet determined. The camera is so-so.

There are some ideas I want to work on, and plan to buy another phone soon. There is an Elephone model that has some features that I want to experiment with.

Bad purchases

November 12, 2014 — BarryK
I have explored various input devices to use with my Android smartphone.

Actually, I have my sights set on a Samsung Galaxy Note 4, as I am "sold" on its S-pen stylus. The Galaxy Note series have a Watcom detection layer on the screen, just like digitiser tablets, which makes the S-pen a delight to use.

Anyway, I don't own a Note 4, so I explored alternative input devices for my current Android phone (other than my finger, that is).

There is nothing that comes anywhere near an S-pen. That includes the bluetooth stylii that are available for smartphones.

But, I did make a couple of fairly budget purchases, a capacitive-pen and a bluetooth mouse. Both were a disaster. To warn others, I have created a special page:


Solar power page updated

September 21, 2014 — BarryK
Solar Power is the first page of my "traveling light" series.

I recently acquired the Voltaic 6W solar panel and V15 power bank (battery) kit, and have tested it and updated my solar power page.

The URL has changed. Please go here:
