Galaxy S 4 Explosion Burns Hong Kong Home!

A Hong Kong couple have been displaced after an exploding Samsung Galaxy S 4 smartphone burst into flames, burning their house to a crisp.

The man, identified in the original Xianguo.com report only as Mr. Du, claims that his phone, battery, and charger were all legitimate Samsung products, but that’s now difficult to confirm since his home and everything in it were destroyed.

Hong Kong House Burned Galaxy S 4

According to the translated report, Du sat on the living room sofa playing the game “Love Machine” on his charging GS4 when it suddenly exploded. In the heat of the moment, he threw the device onto the couch, which caught fire. The flames then spread to the curtains and the rest of the house, “out of control,” Xianguo said.

Du, his wife, and his dogs managed to escape the house unscathed; neighbors were temporarily evacuated as firefighters fought the flames. Almost all of the couple’s furniture and appliances burned to ash, the news site said, adding that their Mercedes parked outside was also damaged.

Whether or not the true cause of an entire house fire was a singular 5-inch smartphone remains to be seen, though a fire department investigation initially resulted in a report of “no suspicious circumstances.”

Samsung did not immediately respond to PCMag’s request for comment, but told Xianguo that it will “carry out detailed investigations and tests to determine the cause of the incident.”

Last year, a Galaxy S III owner in Dublin was driving in his car when the device caught fire.

Cell phone safety is increasingly becoming an issue in Asia, where two cases of iPhone shock occurred within a week of each other this month.

Samsung caught cheating in Galaxy S4 benchmarks

Cue the Lance Armstrong and Alex Rodriguez jokes, Samsung has been caught using performance-enhancing code to beef up the Galaxy S4′s test scores. It’s been discovered that the tech giant has programmed the handset to increase its clock speed during certain benchmarks.

The claims were initially made in the forums of popular 3D graphics site Beyond3D, and have since been confirmed by the hardware specialists over at AnandTech. The S4 specifically enables full speed GPU during testing, and then reverts to slower speeds for everyday usage…

Here’s the original claim from Beyond3D:

“I’m currently doing GPU overclocking and voltage control in the kernel for the 5410/i9500 and was screwing around with what was supposed to be a generic max limit only to be surprised by what it actually represents.

This GPU does not run 532MHz; that frequency level is solely reserved for Antutu and GLBenchmark* among things. The GPU on non-whitelisted applications is limited to 480MHz. The old GLBenchmark apps for example run at 532MHz while the new GFXBench app which is not whitelisted, runs at 480MHz. /facepalm”

So essentially, the Exynos 5 Octa (5410) SoC in the international version of the Galaxy S4 has a 533MHz GPU clock that’s never used. The handset runs apps and games at 480MHz, likely due to battery life and other compromises, but switches to 533MHz for certain benchmarks.

Here’s AnandTech’s findings:

“Running any games, even the most demanding titles, returned a GPU frequency of 480MHz – just like@AndreiF alleged. Samsung never publicly claimed max GPU frequencies for the Exynos 5 Octa (our information came from internal sources), so no harm no foul thus far.

Firing up GLBenchmark 2.5.1 however triggers a GPU clock not available elsewhere: 532MHz. The same is true for AnTuTu and Quadrant.”

And what’s worse is the site found the same behavior (on the CPU side) in Qualcomm versions of the Galaxy S4, as well as other processors. This seemingly indicates that Samsung isn’t just cheating on benchmarks for one handset, but it’s more of a widespread company policy.

So why does any of this matter? Well for starters, it’s very misleading. What if someone were to compare benchmark scores on multiple handsets, and buy the S4 based on it coming out on top? Or what if you bought it thinking it could handle graphics-intensive tasks, and it couldn’t?

What Samsung needs to do is start opening up these higher GPU speeds to all apps/games, or stop using them to game test scores. It’ll be interesting to see what, if anything, comes of this discovery and if any other handset makers, like Apple, are guilty of similar behavior.
