Each variation of the Galaxy S3 had to first operate within the industry standard for the major puzzle pieces: the FCC guidelines, then GSM or CDMA standards, LTE specifications, and others. AT&T, for instance, is part of the 3GPP (3rd Generation Partnership Project) for LTE, GSM, and UMTS, so the phone had to meet those requirements before AT&T's own testing, a final hurdle for the Galaxy S3 and any other handset on a release schedule. Each carrier also issues a list of conformance and performance tests to make sure that the fundamental capabilities work according to spec -- can you place a call and send a text? Do apps behave as expected? How quickly does data flow under different scenarios for each megahertz band?.

Field testing is also involved, with real live humans checking for app and user experience defects, You know all those third-party apps preinstalled on your device? A chunk of the testing process centers iphone xs / x wallpapers - grey leopard around making sure those apps work correctly, according to Lee Rudolph, AT&T's area vice president of subscriber product engineering, The entire testing and vetting process can take weeks, "We find lots and lots of issues with every phone we test," Rudolph told CNET in an interview, Ask Rudolph and he'll tell you that keeping phones from freezing and hanging is one of the hardest things to get right, "One of the areas we really look at is the stability of the device, or resets, How often does it freeze or get hung?" he said..

"We have an iterative process with the OEMs where we give them feedback," Rudolph continued. Underpinning the testing efforts are a bug system and procedures for charting test results, videos, logs, and screenshots. Speed bumps and blocking bandsEven though the vast majority of phones are already "optimized," seeing what you lose when bringing an unlocked phone onto the network is another way of showing what it takes to make individual devices and the network play nice. LTE is on the rise around the world, but even when global phones support the standard, they may not work equally fast in every country. Just as voice and 3G data travel over different frequencies, so does LTE.

If your network in question doesn't support the same bands as the phone, you'll have to accept slower data speeds, or plan to connect to a lot of Wi-Fi, Synchronization secrets, roaming, and moreA lot of synchronization goes into play between the network and the phone, and if this intricate dance skips a beat, your experience ever so slightly suffers, Let's take roaming, for example, In addition to the network speed iphone xs / x wallpapers - grey leopard limitations you may see, the quality you get when roaming isn't guaranteed, An unlocked device could be left out of carriers' domestic agreements, which means leaving a carrier's home coverage area could cut off your network connection completely..

The handset's radio frequency, or RF, also plays a major role. A phone with sensitive RF transmission helps control how fast the browser opens, a standard that carriers enforce when approving phones for their networks. Then there's the question of battery life, which is dependent on the efficiency of both the device and the software that runs it, but also on the network. In order to save their batteries incrementally, and on a small scale, devices go to sleep for milliseconds at a time. But they must also constantly wake up to check the network for incoming calls, messages, and other events.
