Blackberry Z10 hardware: Not all versions have the same hardware!

While the BB market has been declining rather fast, specially among the enterprise users, I felt i had to try out the Z10 and see what new OS and hardware was capable of, since the Z10 and the new BB10 platform has shown good promise, but to many this maybe a year too late in entering the market.

Hardware

The previous Blackberry units very much like the Nokia smart phones running Symbian and Windows 7.x ran rather outdated hardware due to the fact that the operating systems they ran were not supporting modern multi-core hardware, let alone the capabilities of the single-core hardware.

However with BB10 and the Z10 (and now with the Q10 and Q5) Blackberry like Windows Phone 8 has leveraged far more modern and capable hardware.  The hardware in the Z10 maybe modern, but the Snapdragon S4 Plus now is a mid range processor/GPU in the Android space which are now running powerful quad-core and octa-core units.  While Apple may feature a dual-core processor on their current units, and Apple’s strategy of putting very powerful graphics (which is still a match even for the latest Android units) makes the Apple units more potent than the Z10 hardware.

Yet its unfair to compared a platform by the hardware specification alone, since with WP8 we saw the same hardware provide super smooth performance that an Android device fails to achieved. Similarly the Z10 with the new BB10 platform while having its peculiarities offers great multi-tasking, and smooth functioning, and the web browsing performance is very much in tag with the Android quad-core units. 

Not all hardware is the same, Asia and Middle East phones have older Texas Instrument processor

With BB having only a  limited set of models (but compared to Apple one might say they have a wide variety!) i expected that all Z10 units to be the same with possible differences in the antennas for regional support.  However to my surprise this was not the case.  The antenna support for different 2G/3G and LTE was expected, but what i did not expect was that the actual running hardware to differ.

Seemingly BB decided that LTE was not for the Asia and Middle East market phones, and thus decided to eliminate LTE support on this phone, and also by making this decision opted for a totally different chipset for phones of this market.

The key change as you can see with the ST100-1 is that it uses an older TI OMAP processor.   Whilst the processor maybe old, the performance of this processor is still very good but in performance test run by users owning both the models, the browsing performance is significantly different with the Qualcomm S4 Plus unit performing nearly 1.5-2x times better.

The other advantage the Qualcomm unit has is that its made with a new fabrication process (28nm) compared to the TI OMAP unit (45nm) which should mean it should run cooler and possibly have an advantage on the battery usage when on 2G and 3G mode (LTE mode is known to be a power hog).

When you compare the GPU the difference is less obvious as the PowerVR 544 GPU can be more powerful if its the multi-core version (which is what the Apple IPhone uses) compared to the Qualcomm Adreno 225 unit.  However if its a single core PowerVR 544, then the Adreno 225 GPU will be far superior. 

The edge the PowerVR will have is that the older PlayBook device also ran a TI OMAP + PowerVR combination, but with sales bending greater to the Adreno based Z10, will new games be targeting the Qualcomm units?

The impact of this hardware change is also being felt on updates, with the Z10 sales being greater in volume in the US and European markets, the STL 2/3/4 models get more frequent updates than the STL 1. 

With the antenna differences marginal its is very weird why Blackberry opted for a two model approach (and they have done the same with the Q10 as well).

I found an STL100-2 with great difficulty as most phones in my country were STL100-1, or units brought from USA and Canada which meant the LTE would not work (we use LTE 1800Mhz).

Firmware Upgrades

Make sure you have the correct OS to leverage the hardware and app market

When i got the unit it ran a 10.0.9 version of BB10, and since i did not have LTE compatible SIM i disregarded this to be simply because my SIM not supporting.  However i faced a problem that i could not install Skype (beta) which was released on BB World recently as it required the platform to be 10.1.x. 

I promptly tried the OTA (Over the Air = phone upgrade) which surprisingly said there were no updates.  This worried me, and the initial forums i read said i should update this with a leaked ROM.  I was on the verge of downloading a 920MB size download running 10.1.2xxx when another forum indicated that i should backup my phone,and try the update using BBLink.

The advise was good, as it prompted me with the availability of a new update of the 10.1.x range.  The update was large, around 1GB in download and the phone was updated to 10.1.1720, which was far from the latest but still better than what i had.

The good “side effect” of this update was that it now lists 4G as an option in the connection, even though my SIM is still not an LTE compatible.  It seems BB enables the settings based on the provider, and these updates come along with new firmware.  The evil “side effect”  of this update was a bug where the text message app no longer is able to match SMS received with the contacts which is driving me crazy!

Why Blackberry can’t provide small patches as done by Android, Apple, Microsoft for their platforms is a concern, as downloading 1GB each time to me is crazy! 

Your firmware upgrade depends on your SIM, not where your phone originated from

Many things to learn is what i have gathered with my first time move to a Blackberry devices.  My reading as i got to know the phone also found that your update depends on your SIM on the phone rather than what market your phone was made for.

For example though the phone i got was from European origin, since i have a Dialog SIM from Sri Lanka, the update i get will be based the approved firmware and features for Dialog.  It seems if you have an deactivated SIM, the update will still come based on the provider of the SIM if you are updating via a PC using BBLink.  A workaround suggested for getting updates that are not available from your providers is to get an old SIM from another provider from Europe or US so that you can get new updates faster.
