27/07/2018, 0923 Page 1 of 1 The Sony Android TV Experience (2018/Nougat) Deutsch (via Google Translate) I am not really a video purist and there are lots of reviews which cover image quality of today’s TVs in great detail. So I am concentrating more on the functional aspects which reviewers tend to ignore but are in my opinion much more important to the satisfaction of the average user. This review applies to any Android TV based Sony product to date, as apart from the panel, all are based on a similarly performing MediaTek processor and pretty much the same operating system. The purpose of this review is to reflect the current state of Sony’s integration of Android TV, therefore being subject to frequent changes based on latest findings, but also to give advice on how to squeeze the maximum out of your Sony Android TV.

They also announced (via FlatpanelsHD, Feb. 2016) that the upcoming HDR capable models are supposed to feature YouTube HDR playback: YouTube will also start streaming in HDR quality later this year, using a new VP9-Profile 2 codec that brings HDR support to Google’s VP9 video format. Sony’s Motoi Kawamura, Head of TV Product Planning for Sony Europe, confirmed to FlatpanelsHD that the 2016 models will support VP9-Profile 2 and be capable of streaming YouTube in HDR. We saw a demo at CES and it looked very good. Source1 | Source2 Something seems to have terribly gone wrong though. As it turned out, Sony put the old BRAVIA 2015 (also known as ATV1) platform on the whole spring 2016 line-up (XD85/SD85/XD93/XD94) without publicly communicating it. Those models therefore also lack the ability to decode VP9-profile 2 (VP9.2) video which hasn’t immediately become obvious due to a lack of respective content. With the advent of YouTube HDR, Sony chose to stay mum as to why their expensive premium TVs from 2016 (XD93/XD94), actually featuring the display technology to properly reproduce HDR, are not able to play it back. But the crucial part is yet to come as the cheap summer line-up (XD70/XD75, XD80/XD83), which has only been released 3-4 months later, finally received the new platform called BRAVIA ATV2. So after 3-4 months on the market, the expensive March 2016 models have already been rendered out of date. That is pretty bad mismanagement and misinformation on Sony’s behalf. Basing different models with the same nomenclature from the same model year (being released in close proximity to one another) on platforms from different generations is a big no-no. Especially if the cheap entry-level models get the faster and more capable hardware platform than the expensive premium models. Samsung released a firmware for ALL their HDR capable 2016 models, enabling YouTube HDR playback via VP9-profile 2 decoding from day one. More than two years later, at CES 2018, Sony still had nothing to say about YouTube HDR. So they for sure did not have a working demo back in early 2016. The BRAVIA 2015 platform also failed to receive the promised Marshmallow update throughout the whole year of 2016, having been delayed numerous times. It wasn’t until February 22nd 2017 that it finally started rolling out in Europe, just to be pulled again one week later for another two months due to severe installation issues, see Software Support. Keep in mind that nVIDIA has already started rolling out next generation Nougat(!) for their SHIELD TV in January, so being more than one year ahead of Sony. Sony recently also started to abandon major features which they have actively been advertising in the past, like for example all TV guide functionality inside the Video & TV SideView app or the Opera TV Store. And if you hoped 2017/2018 would become a year without any serious affairs, Sony again proved us all wrong. The Dolby Vision firmware update, which Sony promised for certain models back at CES 2017, finally arrived more than one year later. As if the delay wasn’t bad enough, users had to find out that the feature only worked for several select stock apps (Netflix, Amazon Video), but not for all of them (like VUDU) and not for external media players connected via HDMI (like Ultra HD Blu-ray players, Apple TV 4K or Chromecast Ultra) as Sony/Dolby had to come up with a new profile for displays that have not been designed with Dolby Vision in mind from the beginning. Luckily, most HDMI source devices seem to be flexible enough to adapt this new profile via firmware update. So after having waited for over a year already customers have pretty much been taken back to square one. Hardware Platform In 2015, Sony released their 1st generation Android TV platform called BRAVIA 2015 (also known as ATV1), hosting the MediaTek MT5890 SoC, actually being a renamed MT5595 which is supposed to feature four 32-bit ARM cores in a big.LITTLE configuration (2x Cortex A7 + 2x Cortex A17). It seems however, that the LITTLE cores (Cortex A7) have been removed or made invisible to the operating system, so actually being dual core rather than a true quad core. MT5890 inside Philips Android TV sets indeed features true quad core with all cores being visible to the operating system. GPU is an ARM Mali T624 with three shader cores which is not suited for any serious gaming. The newer “BRAVIA ATV2” platform, which all models released after July 2016 are based on, features the MT5891 (MT5596) SoC with four equal 64-bit ARM Cortex A53 cores. An A53 core is quite a bit slower than an A17 core at the same clock speed though. So single threaded applications might very well run slower on the newer SoC. For an operating system like Android, where apps in the background are able to do all kinds of nasty things, more cores might do some good to the overall responsiveness though. The GPU has been updated to ARM Mali T860, only comprising two shader cores this time though, resulting in only mediocre performance improvements compared to the previous MT5890. So even the 2nd generation platform is not remarkably faster than 1st for both, CPU and GPU tasks. The bigger issue of the early 2016 models still being based on the old 1st generation platform is probably long-term support as the MT5890 lacks support for 64-bit, OpenGL ES 3.2 and Vulkan. But Sony/MediaTek will most probably be dropping support altogether sooner than Google will be phasing out 32-bit or OpenGL ES 3.1 in order to render the MT5890 incompatible. If you are not a passionate gamer in the hope of trading your gaming console for a Sony Android TV and are happy with the standard video formats that the integrated SoC is capable of decoding in hardware, the performance of the MT5890/MT5891 is probably sufficient for most common TV tasks. As an iPhone user I have to say that navigation isn’t exactly smooth on Sony Android TV with apps starting rather slowly. More mature operating system and drivers could help sustaining performance over a longer period of time. Android is not very good at managing resources. Reboots every now and then are inevitable. The long power button press quickly becomes your best friend. Sony 2017 and early 2018 models are still based on the MT5891 (2nd generation platform) from early 2016. Performance therefore still leaves to be desired. Sony currently does not deploy MediaTek’s 3rd (MT5597) or 4th (MT5598) generation Android TV SoC. Probably not worth the effort anyway as the CPU didn’t receive a major upgrade, GPU has even been downgraded to an OpenGL ES 2.0 compliant Mali 450 from 2012! The main goal of MediaTek’s Android TV SoC line-up is clearly cost effectiveness. There is nothing premium about it which Sony claims their products to be. Android TV It is hard to get excited about Android TV. To be fair though, others haven’t cracked the TV business either, with Apple TV probably coming the closest in terms of content navigation with its fast processor, deep Siri voice integration and TV app, also offering the most complete list of relevant streaming services directly on the TV without requiring a mobile friend. In case of Android TV, not only does it fail to be revolutionary, you will also find unfinished business in pretty much every corner. Android TV just doesn’t feel ready for prime-time. This is true for its latest iteration Oreo when looking at the sorry state of the Nexus Player, but even more so for the Sony where we are at least 1-2 iterations behind. TCL perfectly demonstrates the segmentation we are currently experiencing in the TV world, putting the Roku OS on TVs in the United States while using Android TV here in Europe.
