The latest software update to the Samsung Galaxy S3 upped it to use Android 4.3, but included a whole bunch of Samsung bloatware. From a full charge, it was only taking 20 hours to run down flat, with it feeling slightly warm all the time. There was also a really annoying app that was requesting I sign into Facebook after each restart.
From what I can see, there are a bunch of things that you can disable to improve the battery life & get things back to normal. Here’s what I did;
Go to.. Settings > More > Application Manager > All
Open & disable each of these.. (obviously if you use a particular service, like Dropbox, leave it alone);
Music (the official Top 40 app)
Samsung Backup Provider
Samsung Browser SyncAdapter
Samsung Calendar SyncAdapter
Samsung Cloud Data Relay
Samsung Cloud Quota
Samsung Contact SyncAdapter
Samsung Push Service
Samsung SMemo SyncAdapter
We have a tablet that we put in a headrest mount for the kids to watch on longer journeys. In the past I attached an FM transmitter so that audio could be fed through the car stereo, and I could control the volume from the dash. The only problem with that was local radio stations in other regions stomping over the FM signal I’d pre-set earlier in the journey.
I bought the Bluetooth audio receiver from Justop. It’s the BTR006 model which apparently has some updated chipset. It’s about £15 on Amazon.
This tiny unit draws power from its built in li-on battery (or any USB port) and when fully charged will allow for 8-10 hours of use, and something like 250 hours of standby.
It was easy to pair up with my Samsung Galaxy S3, and Blackberry Playbook.. both of which will be using A2DP. The signal travels 5-10m without problems, but at extremes, the signal gets scrambled by walls/people. For my use, which is for in the car (tablet with the kids in the back) it works a treat.
The only thing I don’t particularly like is the tiny power socket which uses some non-standard plug instead of micro or mini USB. That’s a real pain when I have loads of micro USB-ended adapters kicking around.
One of the nice features of the Humax HDR-Fox T2 is that it’ll stream your standard definition recordings over your network to DLNA clients. I’ve had a it streaming video onto a PC running XBMC, but wanted something more portable for catching up with some TV whilst I’m getting ready in the morning.
As long as your Android phone is relatively recent, there are a bunch of DLNA clients.. the one I’ve had the best results with is Skifta. Then I’ve got MX Player installed which will handle video playback. The thing I like about MX Player is the gesture control for skipping through the program (swipe across), and adjusting volume (swipe up/down).
I’m running that on a Samsung Galaxy S3, and it works really well. It’s just slightly too small when it’s across the room. It would be better on a tablet, and I have a Blackberry Playbook (from their developer programme).. the only problem has been the lack of a DLNA client.. until just recently, when I found KalemSoft Media Player.
The app is currently being sold at £5, which was a bit more than I’m used to paying.. but the reviews were almost all really good, so I gave it a go. Here’s the app running with my Humax HDR-Fox T2;
As you can see, it’s really fast to browse the folders and start playing back video. It even manages HD if you’re running the auto-decode package, although I had buffering issues when trying to play it back over my network.
KalemSoft do a PC service which will share all your video from there too; I’ve found it works really well.. better than TVersity, and the built-in Windows media sharing stuff, both of which seemed to take ages to index my stuff, and then didn’t even work well after that. Apparently it can be configured to share stuff out over the Internet (password protected too), but I don’t need that feature. It can also stream live TV if you’ve got a TV card.
In Feburary 2012, Blackberry updated the OS for their 7″ Playbook tablet to v2.0. This introduced compatailbity with Android-based applications whereby developers can simply repackage, code sign, and submit their Android apps into BlackBerry App World. It also means you can take any Android app (that hasn’t gone through this process) and sideload the app yourself.
Since I develop mobile apps for iOS and Android using the Titanium platform, I was interested in how much effort it would be to get my existing apps working on the Playbook. There are plenty of posts on how to take an APK and sign it correctly for App World, but what took me a while to figure out, was which version on Titanium was compatible with the Playbook.
After some experimentation, I’ve found that if you package your app against Titanium SDK 1.7.5, it’ll work nicely on the Playbook. Version 1.8.x won’t work (hmm, maybe it’s V8 vs Rhino.. V8 definitely doesn’t work…). Certain pieces of code may also cause the app to crash (whereas it won’t crash on a proper Android device). The one thing I hit, was passing url:null, into Titanium.UI.createWindow will crash the app, whereas that’s absoutely fine on iOS and Android.
The other small advantage of using the 1.7.5 SDK is that the resulting APK is a lot smaller, although since the current Playbook only has Wifi this is less of an issue than it is on a mobile phone.
Now we have the APK, you just have to go through the app packaging/signing process as detailed elsewhere on the web, or in Blackberry’s official documentation. This new GUI-based tool looks like a good place to start if you don’t like working from the command line.
In the last few weeks the price of the Blackberry Playbook has plummeted further, to £169 in the UK from retailers such as PC World. At that price it deserved some research into what it offers & whether it’s worth a look. The tablet itself is solidly built, with a decent amount of processing power & good multi-tasking abilities. There’s an app store that offers a fair number of apps, including the obligatory Angry Birds, Plants vs Zombies, and useful stuff like free VNC clients.
The 7″ screen looks crisp & vivid, and isn’t as cramped as I’d imagined it would be. I’d viewed someone’s Samsung 7″ tablet so knew what to expect. Browsing the web on it is slick & fast, plus it’ll play Flash videos, so iPlayer, 4oD and other sites all work on it without a hitch.
The OS is soon to get v2.0, and that’s where things get even more interesting; that opens the Playbook up to the Android Market, allowing it to run a majority/proportion (not sure which yet!) of Android apps. OS2.0 will also offer MKV support, but what codecs are actually covered is unclear.
Built-in storage is limited to what you initially purchase (e.g. 16Gb), and there’s no SD card expansion. However, if you root the Playbook, there’s a method to add USB-host functionality, allowing you to attach USB flash drives.
A micro-HDMI connector allows it to mirror the display to a TV without proprietary adapters & it just works!
Here’s what you need if you want to hook it up to a TV (a few different cable lengths included):
Micro HDMI to HDMI adapter = £3.56
And here’s what you’d need to connect a standard USB flash drive
For the back of the car, I’ve gone for a generic headset mount that can also mount an iPad:
And to protect it from scratches and minor droppage in the house I bought the official faux leather convertible case, which beats the hell out of the horrible case it ships with.
After a few hours of research I knew it was a good deal, bought one & haven’t been disappointed. It *is* a bargain for what you get :)
I’ve owned a Motorola Milestone for some time now.. but it’s never been the slickest of experiences and since the 2.2 Froyo update things have been a bit laggy. I’d started to look at custom ROMs, but the problem I see with custom ROMs is the risk of bricking the device, and there are a fair number of bugs in the custom ROMs which may mean I’d need to keep on top of the latest releases.
Instead of going all the way & installing a custom ROM, I went part way & rooted the phone using SuperOneClick, carefully reading all the instructions beforehand. I still messed up & didn’t run the app as Admin.. killing the app & re-running it fortunately didn’t have any nasty side-effects :)
Once the phone was rooted, I did very little else until I spotted this nice list of apps on Lifehacker. The one that peaked my interest was SetCPU, but when I ran that it topped out at 550 Mhz, which led me to find Milestone Overclock which allows you to overclock the phone without having to install a ROM that supports higher frequencies (like the official 2.2 update from Motorola).
I’m now running the phone comfortably at 800 Mhz.. but only when it needs it.. SetCPU will scale back the performance depending on what the phone is doing, which really helps with battery life.
I’ve been looking to replace my ageing Xbox which has reliably run XBMC for over 7 years with a box that can handle HD content, as well as acting as a NAS & download server. The Zotac ION box caught my eye, since the latest media center apps now support hardware acceleration for video playback & the nVidia ION GPU is supported.
I bought the kit as a bundle from Mini-ITX.com and fitted a 32Gb SSD for the operating system, and a 1TB Western Digital Essentials HDD which would be attached via USB & powers down when not in use. The shopping list looks like this;
- Zotac ION-ITX-A Motherboard with Dual Core 1.6GHz Atom N330
- 2GB or 4GB DDR2 800 RAM included
- M350 Universal Mini-ITX Enclosure
(bundle costing £233 from Mini-ITX)
- OCZ Onyx 32GB SATA II 2.5in Solid State Disk
(about £50 from Amazon)
- 1TB Western Digital Essentials
(about £45 from Amazon)
For the OS I wanted to use Windows 7; that’s what I’m most comfortable writing scripts + code for. The Linux distros for XBMC Live look pretty good, but there was too much of a learning curve involved for adding in the extra features I wanted.
Installing OS From USB
Since there’s no optical drive, I opted to install Windows 7 from a USB key. I actually used a 4Gb SD card from my camera & a SD card reader, and followed these instructions to make it bootable & have the Windows 7 installation on it. Installation went without a hitch.
After installing the OS, I updated with the latest nVidia drivers, and started installing apps like XBMC. The latest Dharma release of XBMC supports hardware acceleration using DXVA2, however I was unable to get it working with 1080p content & gave up after a couple of hours. I then tried Media Portal which worked perfectly with whatever I threw at it. There’s a brilliant guide on how to configure Windows 7 and MediaPortal by Rhys Jones, which is useful to follow if you want to optimise your HTPC setup.
Next up was getting the remote control working correctly. I had a cheapo CyberLink remote, plus a Harmony 600.. I used the Cyberlink IR Reciever & mapped up keys into the Harmony 600. Some of the buttons worked, some didn’t. I ended up re-mapping the numeric keys to certain MediaPortal features using one of the plugins. I also re-mapped the MCE Green Button so that it runs MediaPortal (see this guide.. scroll to the Green Button heading).
The HTPC also acts as a NAS + handles any downloads, so I’ve written a bunch of scripts to handle certain situtations.
- Timed execution of certain download tasks using Windows Scheduler. Making sure that the tasks don’t bring the HTPC out of sleep.
- Execution of scripts when the HTPC is brought out of sleep (like making sure MediaPortal is running)
Keyboard + Mouse Control
For times when I need a keyboard, I’m running Unified Remote on the HTPC and the client on my Android phone. This allows me to control most aspects of the HTPC via my phone, without having to buy extra hardware like a wireless mouse/keyboard.
