The Oppo phone often dropped connection for small periods of time when we were using it, whether with Bluetooth, Wi-Fi or mobile data connectivity. The first of those manifested in connected headphones sometimes disconnecting and reconnecting after a few seconds; Wi-Fi was sometimes a problem playing online games where we’d now and then repeatedly freeze, or be seconds out of sync for other players; twice in our time with the phone data dropped out completely, though restarting the device fixed the error. The Oppo A94 5G has four rear cameras, and it’s the same array as the A54 and A74. Finally, a section in which we don’t need to keep comparing it to its family! The price is the real selling point of the Oppo A94 5G though - despite costing more than its siblings, it’s still great value if you’re looking for next-gen connectivity. In photography, the Field of view (FoV) depends not only on the focal length of the lens but also on the sensor size. It is derived from the lens's angle of view and the sensor's crop factor. The lens's angle of view is a measure of the angle between the two farthest separated points within the frame measured diagonally. Simply put, this is how much of a scene in front of the camera will be captured by the camera's sensor. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content.

Pixels are usually measured in microns (μm). Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. On the other hand, smaller pixels allow for increasing the resolution while preserving the same sensor size.

Make/Model examples

It’s distinct to the experience on the A54, which was nice enough and easy on the eyes, but the A94’s AMOLED is much better, and makes the phone so much nicer to look at, for sure. Performance Finally, the ultra-wide camera does what it says on the tin. There was good consistency in lighting and color between this and the main camera, though snaps could be noticeably distorted at the edges. There’s a widgetised home screen, app drawer, and a nice drop down menu to play with, plus support for Oppo’s “O Relax” app that we’ve played with before, and while that focuses the style of Android more like what Android users expect, there’s also an interface like what Apple users get where everything is on the one screen. Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation.

Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM The performed is markedly improved on where it was in the A54, but the camera is very much the same, and that’s not entirely a bad thing. Another day, another Android phone, because if you’ve seen one of these recently, you probably know how to use it. The improvements to the screen and design are nice, but we’d have appreciated a little more oomph to make the phone shine well and truly over its less expensive siblings, for sure. Before attempting any repair, be sure to ground yourself by using an ESD (electro-static discharge) strap. This will prevent static electricity from damaging the electronic components within the phone.Front camera Modern smartphones have one or more front cameras and their positioning has led to various design concepts – pop-up camera, rotating camera, notch, punch hole, under-display camera, etc. Pixel size This was a problem with close-up shots (flowers, food etc), and not so much with snaps with a wider field of view. And these pictures were still better than macro ones, which had strangely crushed darker areas and an odd yellowy hue. A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.
