Another Galaxy Note 3 long-term report


Sitting idle and disorderly in my apartment after a very heavy dinner, I thought I could jot down a few long-term use notes of my Samsung Galaxy Note 3. This version is now 8 months old, and is the Exynos (octa) SM-N900.

1. Battery Life


Still lasts a full day. My usage involves :
  • Constant CalDAV sync with the corporate calendar (this actually works quite well with e-groupware. I use the CalDav-Sync app and this integrates coherently with S-Planner or any other calendar app of your choice (I use Google's own Calendar app). 
  • Heavy usage of WhatsApp.
  • Constant e-mail sync for Gmail and MailDroid Pro. (It is an excellent app, if you do not like the interface of the excellent free and open source K9-Mail).
  • Samsung's S-Health "Walking Mate" app constantly tracking steps taken and distance walked daily (with built in pedometer).
  • Occasional web browsing.
  • 1 hour of music (jogging, using S-Health).
  • WiFi or HSDPA all the time.
  • Occasional use of the S-Note app.
  • Constant VPN connection (using OpenVPN)
  • Constant VoIP availability (using the Bria app)
  • Constant Skype availability using the Skype app, as well as other messaging accounts using the IM+ Pro app.
  • Several widgets.

As you can see, the battery is at 41%, at the end of day (1918h), which is not so bad with the type of usage above. The 3300MAh battery performs excellently in my opinion - I would like to think I am a heavy user :-) . 


2. Build Quality

This has never been one of Samsung's strong points. The device has taken a few falls, both screen and back down, sometimes falling on its corners. I have also accidentally forgotten it in my back pockets an sat on it occasionally, sometimes roughly. I must say it is still as solid as ever, although the edges are a bit chirped from the falls. (I do not use any jacket or pouch as they enlarge an already big device). So, although slightly deformed along the corners in that silver shiny thing, the gadget is still good to go. It feels like it could take much more abuse for years.

To put this into context, my wife's iPhone 5 had a simple fall and shattered its screen. The device is still stashed somewhere, as the cost of fixing that screen is about the same as a brand new Google Nexus 5.

3. Performamce

I enabled device encryption, a process that took a while to complete. (OK, this took about 10 minutes). I imagines it would slow down the device, but this hasn't. I must state that some apps do not work as well as they used to on the Note 2, such as "Smart Home Control",  Ultimate Rotation Control and some launchers. A few other niggles:
  • All SD cards make the device devilishly hot. I have given up on all of them and thankfully, there is 32GB on board.
  • The InfraRed functionality seems to work OK with some apps, but not others.
  • It sometimes charges very, very slowly :-)

4. Multimedia/Entertainment

I use Poweramp for music. It performs exceptionally and is highly customisable. It connects seamlessly with the bluetooth unit in my vehicle, which is a cool thing. All videos thrown at the device are played seamlessly, except those with the AC3 audio codec. I suspect MX Player will not mind that codec though, although I prefer the built-in video app.

Camera is very bad in poor light, but hey this is a smartphone, not a point-and-shoot! In relatively good lighting, the camera is acceptable.

5. Productivity

This is where I give the device a 5/5. Ever since I acquired it, I gave away my Samsung Galaxy Note 8 tablet and sold my iPad Air. I did not use them for months. That is how productive and useful the Galaxy Note 3 is. I have not had a single instance when I needed to use a tablet instead of the Note, in which case I would reach out anyway for my trusty old MacBook Pro 7.1 (which has started caving in to age) :-) !

Do I recommend the device, much as it is mid-way its product life cycle? Absolutely. My only gripe is that while other parts of the world already has KitKat, I'm still stuck with 4.3. From what I read though, it does not look like KitKat offers any leaps in performance anyway.

6. Geeky Stuff

  • Cynogenmod - is not yet available for the Exynos version, sorry. If you want cynogenmod, you want the Snapdragon.
  • Rooting: This is not very secure. I do not recommend it. If you want the shell along with its usual binary utilities for doing all sorts of things, try the Busybox non-root app. It offers you everything you want without rooting, and integrates well with Android Terminl Emulator. 




  • SSH: Busybox/Android Terminal Emulator gives you an ssh client on the shell (above).
  • PGP: Depends on what you want this for. If you want to send encrypted mail, use Maildroid, K9-Mail, the built in e-mail app or just encrypt some text using the free APG app.
  • Time-of-flight camera: Sorry, you can't have this. If you do, just get the Xbox one :-)

PGP with stock Android Email Client


Without getting into the innards of what PGP is and who it is for, I will assume that you are here because you straight away want to know how you can use PGP on your android device.

My setup is here, and I hope this works across most android devices, but just in case:

1. Android 4.3
2. Samsung Galaxy Note 3 SM-N900
3. Built-in e-mail client.
4. Assumption: You already have a key pair you wish to import and use.

(If you want to use a separate e-mail client, I highly recomend K-9 mail, which works very beautifully with APG, all available free in the Play Store).

  1. Transfer your key pair from wherever you store them, to your device. There are many ways to do this, but i use Dropbox. 
  2. On the device, save the key par to /openpgp/export/ on the built in storage. You can export directly from Dropbox to any location on your device.
  3. Rename the keys to the following format:
     __0x_Pri.asc
     __0x_Pub.asc 

For the private and public keys respectively. For example, if your email configuration is as follows:

E-Mail address: john@xxxxxxx.net
Name: John XXXXNET
Key ID: 0xABCD1234

Your file names would be:

 john@xxxxxxx.net_John XXXXNET_0xABCD1234_Pri.asc
 john@xxxxxxx.net_John XXXXNET_0xABCD1234_Pub.asc

4. On your device, import the key-pair as follows: Settings - your_email_account - More Settings - Security Options - Private (or Public Keys); then click "Import Keys" on the menu option.
Hope this helps.

OSX Lion : No iSync !!!???

After upgrading to OSX Lion, iSync was missing. A quick search confirmed my fears. Apple silently pulled iSync (along with other nifty features) out of Lion. Very annoying.

Implying - I can not sync my Nokia N900's calender/organizer and address book with my MBP.

The good thing's that it's possible to pull iSync from many sources on the web, install it directly to the MBP as usual (along with the plugins for your appropriate smartphone), and you have it working again.

Ahh, I don't think Steve Jobs would have liked to see iSync out of Lion :-( I miss him already!!!

WDS with Vodafone (Huawei B970) and Linksys WRT54GSv7 running DD-WRT

The commonest mobile broadband offerring from most operators is some form of USB dongle (with a data-enabled SIM card inside), which unfortunately limits sharing that internet connection. Welcome the Huawei B970 HSDPA wifi router. A buddy grabbed it for me from Pretoria for 2500ZAR, quite a decent price considering its functionality.

I got a cool place for it in my house, somewhere, some hidden corner upstairs, that's the only place I could get 3G+ HSDPA coverage. Unfortunately, this was not the ideal location for covering the entire house with WiFi.

I grabbed my trusty old Linksys WRT54GS v7 already flashed with an older version of DD-WRT micro, upgraded to DD-wrt v24-sp2, and set it up as a "wireless range extender" or "repeater" or whatever one may call it. Using the stock Linksys firmware, this functionality is not possible.

Step by Step:

  1. Setup the Huawei (aka Vodafone) B970 router, make sure it can properly serve wifi (and net connectivity). It's a lil bit tricky, you need to create a profile for your operator (you must be equipped with your APN + user-name and password if required), then set this profile as the default. The vagaries of this step will not be covered here - refer to the packaged printed manual (in the box).
  2. Grab your Linksys WRT54GS (or any Linksys wifi router with a broadcom chip). Flash it with DD-WRT, the latest build. Instructions to do this are galore on the dd-wrt website. This is a trivial process, depending on the Linksys router you have. If you are wary of this, then just buy the Linksys WRE54G. However, adventure is fun. Congratulations if you have come this far, and are ready to proceed :-)
  3. Open the B970's admin interface, go to advanced wireless settings, go to "wireless bridge", enter the MAC address of the WRT54GS. Do not get the MAC address at the back of the Linksys, but in the dd-wrt WDS page. (Wireless -> WDS)
  4. Open the dd-wrt Web UI, turn off the WAN interface, DHCP and firewall. Ensure the SSID, channel and security settings in the Linksys match those in the B970. Go to the WDS menu, enter the MAC address of the B970 and select LAN. Note the MAC address listed atop and ensure its the same address in the B970. Enable "Lazy-WDS".
  5. In the Linksys "Basic" setup menu, enter the gateway and resolver IP address of the linksys as the IP address of the B970. By this time, I assume you have already setup the two routers to different IP addresses on the same subnet.
  6. Important: Make sure they are in the same channel.
  7. You should be good to go. When you open the "status" page of the Linksys, dd-wrt should show you the online 'WDS Nodes'.
  8. Leave a comment and I'll help you out if you are stuck. I've been rather lazy to add screenshots from both routers' setup.

Nokia E71 - Dead: Very Hot Camera Lens Cover

So, after just 15 months of ownership (may be a little less), the much beloved Nokia E71 has given in to, I don't even know what - nothing. It's dead. All of a sudden, the camera lens cover started heating abnormally, to rather uncomfortable temperatures - even when the phone is turned off, for as long as the battery was in. The battery gets drained in just over 20 minutes, and when it's working, it's completely unreliable. I wont list here what problems there are.

A quick look online revealed many such issues, especially right after the warranty period. Of course I took it to our Nokia dealer for checking (HM Rawat (Mauritius Island)). They need a little over 45USD to "receive it and carry out basic diagnostics" :-) ! That's complete BS. I was already anxiously waiting for the Nokia N900, but this was certainly a deal-breaker. Nokia out of the window for now.

Next in-line? Yes, the iPhone 3GS wins. I hate to admit this, but time has taught me that Steve Jobs has ways of making appealing (and really cool) gadgets that actually outlast most competitors.

Phew!

Maggots in food aboard South African Airways SA160







I was quite amazed to see maggots in the food served to me on SA160 flight from Johannesburg to Mauritius. I showed the food to the senior hostess, she told me that its not her problem, but the food supplier. Talk of customer care (or lack thereof) :-(

GPS on the Nokia E71

What would have been the purpose of spending my hard-earned Mauritian Rupees towards the latest smartphone if i could not put its features to good use? You betcha. I decided to start making use of the GPS function (although, frankly, Mauritius is such a small place that my intended use of the GPS feature is merely to pose on my buddies). :-)

First things first - I combed through the phone's applications to see if there was something I could use out of the box. There was Nokia Maps 2.0 preloaded, but I found that it only has the major roads in Mauritius. In short, it was useless for me. I then looked online for the famous Google Maps, and to my utter dismay, it was worse than Nokia Maps. This left me with one option - to look for a commercial solution.

Naturally, on the mention of GPS, two names come into mind: Garmin and TOMTOM.

I decided to try Garmin first, as it is supposedly more popular. I looked on garmin.com to see if a) There is software that can be installed on the Nokia E71, b) There are detailed maps available for Mauritius. Both were available - but the Mauritius maps are made by a third party partner for Garmin - called Garmap (www.garmap.com) . I was happy to find that Garmin Mobile XT 5.0 that i quickly downloaded and installed to the gadget. I bought a license and unlocked it right away. I later downloaded and installed the Garmal Indian Ocean Streetmaps v 1.0, unlocked it and lo! I was absolutely ready to navigate!

In summary, I can report that the Garmin solution works well on the Nokia E71, but not perfectly:

  • Sometimes, it may take forever to get a satellite lock. When i reboot the phone, it works right after. Another quick hack is to open Google Maps or Nokia Maps first, which takes much shorter to acquire satellite lock, then close it right away (or leave it in the background) and open Garmin Mobile XT. Even with AGPS on, this seems to be my problem, and that of many E71 users out there.
  • The software must be unlocked for it to detect the internal GPS chip.
  • It is not very accurate sometimes. A reboot also fixes this nuance.
  • GPS is a battery hog for the E71 - invest in a car charger.
  • Garmin Mobile XT is designe really for friving, not walking.
Otherwise, this is agreat gadget. I would recommend it to anyone anytime.
