Editorial: Snapdragon Sorrows - Has Qualcomm Begun A Long, Slow Fall From The Top?

Back in late July, the Qualcomm Corporation - employer of over 30,000 individuals at the time - began the process of telling about 15% of those people (eg, over 4,000 gainfully-employed human beings) they were no longer needed. This was after already cutting another 1500 jobs in late 2014.

The company's stock is currently trading near 2-year lows, and while obviously still a very robust company, Qualcomm can't keep putting in these kinds of numbers if it's going to maintain its position at the tippy-top of the smartphone chipset market.

Qualcomm (QCOM - NASDAQ) stock is down over 10% year-to-date. It is down over 20% from its peak, reached in early 2014.

Report: Samsung Drops Qualcomm's Snapdragon 810 From The Next Flagship Galaxy Phone

Samsung and Qualcomm have been reliable partners since the rise of Android, to the mutual benefit of both the phone maker and the OEM chip supplier. But according to this report from Bloomberg, that relationship has hit a rocky patch as Samsung prepares its next flagship phone, presumably the Galaxy S6. An anonymous tipster told Bloomberg that Samsung will decline to use a Qualcomm chipset for the phone after poor testing of the Snapdragon 810, the OEM's top-of-the-line processor.

According to the report, Samsung has found that the 810 often overheats during testing, causing the company to choose its own line of Exynos processors instead.

ARM Announces New Mid-Range Designs, MediaTek Already Has Chips Ready To Go

ARM technology powers the vast majority of mobile devices in the world, and the company has just announced some new designs to continue that tradition. The ARM Cortex-A17 is a new mid-range CPU core that offers improved speed and efficiency for budget devices. That's not all – there is also a new version of the Mali GPU for a complete price-conscious package.

Cortex A12 Mali-T720MP-LG

The Cortex-A17 is not meant to replace the A15 – that's still the flagship CPU core design from ARM. The A17 is a mid-range part that should give chip makers a better option than continuing to use older A9s, the limited A12, or just a bunch of low-power Cortex-A7 cores.

Did You Root Android 4.3 With Chainfire's SuperSU? Update To v1.43 To Fix The 100% CPU Bug

If you've already updated to Android 4.3, whether via an OTA or by flashing it manually, and rooted it, you're more than likely using Chainfire's SuperSU, which carefully works around the new restrictions Google put in place. Cody has a good write-up about why they did it and what's going on, so go read that if you're interested in the details.

Chainfire created the Android 4.3-compatible root method and the updated SuperSU back when the first leaks showed up for the Galaxy S4 but hasn't updated it for a few weeks. During that time, a good portion of users have discovered that sometimes SuperSU causes CPU spikes and starts eating up 100% CPU.

ARM Announces Cortex-A12 CPU And Mali-T622 GPU Architectures, Mali-V500 Video Processing Solution, Coming In 2014

ARM is kind of of big deal if you like mobile devices: they release and maintain the architectures licensed by nearly all the world's mobile System-on-a-Chip (SoC) makers. Today they've announced new CPU and GPU designs specifically targeted ant the growing mid-range market, the Cortex-A12 and Mali-T622. This silicon is powerful by today's standards, but a bit less so than their A15 (Samsung's Exynos 5250, NVIDIA Tegra 4) and T624 (and higher) counterparts, designed for more economical implementation. The basic idea is that mid-range devices, which ARM defines as between $150 and $350 unsubsidized, will get both more powerful and more efficient.

Security Researcher Demonstrates GPS Vulnerability That Could Let Hackers Track Users' Location, Take Over Phone

Over at Black Hat USA 2012, security researcher Ralf-Phillip Weinmann demonstrated a vulnerability in several Android devices that utilized A-GPS to send illicit messages to the device which could, he explained, be used to send a report of the device's location any time an A-GPS message was sent or even be used to gain complete control of the device.

In describing the attack, Weinmann pointed out that, for example, a malicious WiFi network could instruct a phone to relay all future A-GPS requests, even once the device has left the WiFi network's range. This even further drives home the point that you should not join any networks you don't trust.

Goodbye, Amazon Appstore

Today, I uninstalled the Amazon Appstore and bought all the FAOTD (free app of the day) apps I've been really using. Why did I do it? Because, mildly put, the Amazon Appstore app, which is required for all Amazon-installed apps to run and perform their license checks, has affected my battery life in very negative ways. Even if you never open it, it will keep running in the background, using up valuable CPU cycles, keeping the device awake when it should be sleeping.

Now, this may not happen to everyone - it's possible that a combination of events leads to this unacceptable behavior, or maybe it's having certain apps installed - I'm not sure.

Eden To GREEEEN Pops Up On TegraZone With Q2 2012 Release Date, Will Let You Beat Up Steam Rollers With Flowers

During Mobile World Congress nearly 2 months ago, NVIDIA released some details about a few impressive looking upcoming games. One of them was the very original looking Eden to GREEEEN. Eric summarized the game well:

Built on the Unreal Engine, Eden to GREEEEN pits you "against alien machines from another planet" (so we can conclude "alien" doesn't mean "immigrant" here) who are trying to steal Eden's natural resources. It's up to you to save Euphoria, the natural energy of Eden. This totally original story comes with the descriptor "freemium", so we can probably count on some sort of in-app purchases, but NVIDIA promises Eden to GREEEEN won't "skimp on the gaming experience." Fingers crossed.

SetCPU Updated To 2.3, Brings Major UI Overhaul, Many Related Improvements

To any hardcore modder, overclocking (or underclocking) your CPU is one of the best ways to get the most from your device. While some popular ROMs now have the ability to control your CPU baked in, many don't - and in the earlier days, virtually none did. Enter SetCPU - the de facto standard.

The app has long been a favorite, picking up 100,000-500,000 downloads at $1.99 and over 17,000 ratings for an average of 4.5 stars. There's good reason for that: it offers a huge range of ways to tweak your CPU, including profiles, clock speed, voltage settings, and more.
