Some users are reporting that their handset is getting too hot when charging. If you find that your Galaxy S7 is overheating, there are a number of ways to tackle the problem. The other advice, if you suffer from this issue, is to invest in a good chunky case, which typically puts an extra few millimetres between your fingers and the screen. Unfortunately, there’s no fix for this at present, other than that old iPhone 4 ‘Deathgrip’ advice: hold it differently. It can also cause issues when gripping the phone a certain way whilst trying to take a picture, with the shutter button proving unresponsive, or even when trying to type out a message on the keyboard. This can be a particular problem for the Galaxy S7 Edge, for obvious reasons. We’ve seen some Galaxy S7 users complaining that the display is simply too sensitive, and that the palm-rejection feature isn’t doing its job of filtering out incidental presses around the edges of the display. Once your phone restarts, the power and volume buttons should be responsive again. Many consumer-grade home Wi-Fi solutions come up short.While the power and volume buttons might appear unresponsive, holding the power and home buttons together should still reset the Galaxy S7. Here’s this months Pro Tip: “Operating Wi-Fi gateways at maximum permitted power and designing gateway enclosures for optimum antenna spacing translates into high Wi-Fi performance and excellent coverage. ![]() ![]() This is why some mesh Wi-Fi solutions require multiple systems to deliver adequate in-home coverage,” Shane Eleniak says.Ĭalix has the experience and data to back up their design approach: It turns out that only a few percent of deployed Calix home systems need mesh units to complete whole-home coverage. “It is often the case that the performance degradation of consumer-grade routers is compounded, meaning significantly reduced because of lower transmit power combined with inadequate space for antennas. This results in overlapping signals, which in turn limits coverage. This means that such units do not allocate enough space for adequate separation of antennas. Unfortunately, most consumer-grade Wi-Fi systems are smaller than 4.9″ along one axis. In the case of 2.4 GHz and 5 GHz radios, the wavelengths are 4.9” and 2”, respectively,” Shane Eleniak says. “The best solution is to position antennas at least one full wavelength apart in order to minimise their mutual interference. The performance of small form factor Wi-Fi routers or gateways often deteriorates even further as a result of inadequate space for antennas. Ultimately, this approach sacrifices Wi-Fi performance for aesthetics and price,” says Shane Eleniak. They do this in order to target the consumer market with lower-priced, smaller physical units such as plug-in pods or similar. “Some mesh Wi-Fi vendors engineer their systems to transmit at mid power levels of 23-25 dBm. In general, small form factors and lower power leads to poor performance. Above: Shane Eleniak, Executive Vice President of Products at Calix.īut consumers and ISPs should be aware that not all vendors operate at the full 30 dBm of transmit power. We do this to achieve maximum coverage, reach, and performance in and around the home,” says Shane Eleniak, Executive Vice President of Products at Calix. “Some vendors – and Calix is in this category – engineer their systems to transmit at the maximum allowable power of 30 dBm, also known as high power. In practice the maximum transmit power for a Wi-Fi residential gateway is 30 dBm (equivalent to 1 Watt) because 6 dBm is typically allocated for antenna gain.īut wireless equipment vendors often approach the issue of transmit power in very different ways when designing residential gateways or consumer-grade routers and mesh systems. In the US, the Federal Communications Commission (FCC) permits a maximum power level (called EIRP or Effective Isotropic Radiated Power) of 36 dBm for Wi-Fi equipment operating in the 2.4 GHz and 5 GHz bands. ![]()
