Phone repair screen color test vs Lora Sniffer Usage & Stats

People often accidentally break their phone screens. So naturally, they also often have to get their phone screens replaced. The phone screens that are used as replacements in the vast majority of mobile phone repair stores are not original Apple Parts (these parts are called ‘aftermarket parts’), so they are made by many different manufacturers - meaning that the quality of these parts can vary. Sometimes, manufacturers use poor quality, cheap materials, resulting in poor quality screens that can have wildly varying prices. You could be scammed to purchase a poor quality screen for an outrageous amount of money. With the naked eye, it’s extremely difficult to measure and even estimate the quality of these screens. That’s where ColourTest comes in. ColourTest by Procase has been developed to help consumers and retailers alike with this issue. It can give an accurate, numbered measurement of screen quality. Depending on how vibrant the colours in your screen can get, you can get a score from 1 to 255 in all 3 main pixel colours that can appear on your screen, with 255 being the highest score and 1 being the lowest. However, if you don’t get the maximum score, don’t worry! It’s almost completely impossible for an aftermarket screen (or even an ORIGINAL screen) to have a vibrancy score of above 250. Phone screens (including originals) typically range from around 170 (being a low score and an indicator of poor quality) to 240 (an exceptionally high score demonstrating very high quality). There’s also a fourth colour: black. This can give a score on the brightness of your screen, with the same rules and ranges as the RGB pixel colours. For further information, and details on how to use ColourTest, visit the Help section of our website, or download the app and click on the ‘?’ button in the bottom left corner of the screen for a thorough explanation on how to use the app. To receive support, or to give feedback or suggestions, contact us at: procase@outlook.com

Lora Sniffer

The LoRaSniffer App is the user-interface for the LoRaSniffer Device. The combination of both, the device and the app, is a tool for technicians and hobbyist allowing to use LoRa radio communications for testing and network maintenance. The LoRaSniffer Device is a LoRa radio module that can use all possible features the LoRa standard offers. This app is its convenient user-interface. It connects via BLE to the device to allow access to all its setup-parameters, receive communications from other LoRa nodes and send data via LoRa. Using 2 coupled LoRaSniffer devices, it can provide valuable information about network quality in a real-world scenario. The app provides a logging window with features for: formatting of received communications, additional time-stamp and the GPS location where each message was received. Each received message is tagged with "Quality of Signal" information as CRC, SNR, RSSI and carrier-frequency offset. The app allows as well to save the logged data as a visual document in HTML or as JSON protocol file. Messages can be sent as ASCII-text or as binary data. Tools allow to scan for channel activity, calculate transmission times for specific payloads or, if used with 2 devices, allow to gain real-time information to optimize LoRa networks in the field. More, the app can be used as well to update the firmware of the LoRaSniffer device.
