Firmware update certified for Sony Xperia Z3+ and Z4 Tablet; could fix overheating issues

Firmware update certified for Sony Xperia Z3+ and Z4 Tablet; could fix overheating issues
A new firmware update for the Sony Xperia Z3+ (E6553) and Xperia Z4 Tablet (SGP771) has just been granted certification from the PTCRB. The update, which carries build number 28.0.A.7.24 versus the current 28.0.A.6.8, could help to fix issues brought about by the overheating Snapdragon 810 processor, found in each of these flagship devices. 

Even though Qualcomm has apparently revised its controversial Snapdragon 810 SoC, the saga shows no sign of cooling down. This is bad news for the manufacturers who've opted to utilize the octa-core chipset -- particularly Sony -- since the PlayStation maker is currently trying to roll out several new products running the same hit-and-miss processor. 

The Japan-only Xperia Z4 hit the company's homeland amid warnings from retailers and carriers that the device would need mollycoddling, with regular downtime required to stop the handset from overheating. The Xperia Z3+ -- almost identical to the Z4 on paper -- has been dogged with the same issues. Sony has, to its credit, stepped out and admitted the problem, adding that a remedial update will be rolled out post-haste. 

There's no telling whether firmware update 28.0.A.7.24 will help to sort the heat-related problems, or if it's even intended to. A number of Snapdragon 810-powered handsets seem to have been 'fixed' by means of thermal throttling, which, in layman's terms, entails keeping the processor cool enough to run uninterrupted at the expense of overall performance. 

Precisely how and when Sony plans to overcome its Snapdragon 810 woes remains to be seen. But with the Z3 plus making its way to several markets this month, the sooner the better.

Sony hates America? More like Americans dislike Sony and got brainwashed by Samsung and Apple. That's why I say the smartphone industry in the US offers the least competition around the world which is boring. Both sides are wrong if you ask me, most American consumers are not willing to try different things other than Samsung and Apple, and Sony is being a pussycat for not advertising more and launch more phones to all major carriers in the US. If it's because of your Z3V or Z3 T-Mobile not getting updates quickly, then blame your bloody carrier.

The problem is that apple and others HATE sony because they have huge business in USA and obviously USA companies hate it .. They hate: pictures entertainment sound studios 3.Sony mobile industry 4.Etc And that is why they spreading all bad things about smartphones, then sony pictures had problem with that film the interview,with PS 4 network hackings , All these things are done on purpose , to destroy sony in USA. They hate sony they don't want them ..

Well, what you said might be possible. But, why would others hate Sony just because they have huge business in the US? This is business, you earn it, you gain it, you have it. If Apple hates Sony, then why would they still buy camera sensors from Sony? Also, I thought that The Interview hacking were done by North Korean/North Korean Patriots a.k.a. Guardians of Peace?

Throttling is not fixing.

People pay extra dollars for the latest technology then they just throttle it? That's ripping off consumers. You advertise your speed, you better make up for your promises.

Snapdragon 810 does have the technology, and it does have the speed, but Qualcomm ruined it. Sony has no choice but to throttle the speed to prevent overheating issues. Actually, Sony is the one that got ripped off by Qualcomm. Sony was going to use the first version of Snapdragon 810 SoC, but they waited and went with the so-called "fixed" version of the Snapdragon 810 SoC and still has the same problem like the first version. Sony could've went with Mediatek's Helio X series or Samsung's Exynos 7420 or even Huawei's Hi Sillicon Kirin 935 but for some reasons they went with bloody Qualcomm's Moronic Microwave wannabe slowdown crap 810. Hope Qualcomm doesn't f**k up again with the Snapdragon 820. You advertise your speed, you better make up for your promises.

So what, what's the big deal? Just buy and user a cover, or try ignoring the section where it gets hot. How simple is that.

Who cares. I'm running my Rooted Z3 at 3.0ghz, with SetCpu, along with performance mode, instead of crappy on-deman mode. Voltage raised up, along with Gpu raised to 850mhz, instead of 550mhz, as standard that crappy slow that comes with standard. My phone becomes way to hot, but I don't give a rats, cause I no I'm multitasking super fast, and with breeze. Lags, what lags. I'm playing games at much higher rates. Loading Facebook and several other apps way faster than the crappy standard Z3. Though battery runs out 30% faster.

I agree that overclocking makes your phone 'super' fast but be also aware of the load (and heat) that it puts on your components. These guys out there did not just choose that frequency at random..;)

but they said they not gonna implement 810 so don't understand why they did at the end..
