Oppo A21 Additional Information

Oppo A21 MT6763T Helio P23: an 8-core chipset that was announced on August 28, 2017, and is manufactured using a 16-nanometer process technology. It has 4 cores Cortex-A53 at 1650 MHz and 4 cores Cortex-A53 at 2300 MHz. The Mediatek Helio P23 MT6763T is a mainstream ARM SoC for smartphones (mainly Android-based) that was introduced in 2017. It is manufactured in a 16 nm FinFET+ process and is equipped with 8 ARM Cortex-A53 CPU cores. The cores are divided in two clusters, a performance cluster clocked at up to 2.3 GHz (2.5 GHz for a single core only) and a power efficiency cluster clocked at up to 1.65 GHz. The chip also includes an LTE modem (Cat. 7 DL / Cat. 13 UL with Dual-SIM support) and a 802.11a/b/g/n WiFi modem. The integrated ARM Mali-G71 MP2 GPU is clocked at up to 770 MHz and has two clusters (from 32). The integrated memory controller supports DDR4x (Dual-Channel?) at 1500 MHz and LPDDR3 (Single Channel only) at 933 MHz. The video engine supports H.264 de- and encoding but only decoding (playback) of H.265/HEVC.

Oppo A21 Android 10: Android 10 (codenamed Android Q during development) is the tenth major release and the 17th version of the Android mobile operating system. It was first released as a developer preview on March 13, 2019, and was released publicly on September 3, 2019. Android 10 was officially released on September 3, 2019, for supported Google Pixel devices, as well as the third-party Essential Phone and Redmi K20 Pro in selected markets. The OnePlus 7T was the first device with Android 10 pre-installed. In October 2019, it was reported that Google’s certification requirements for Google Mobile Services will only allow Android 10-based builds to be approved after January 31, 2020.

As of November 2021, 27.71% of Android devices run Android 10 (API 29), making it the second most used version of Android. Android 10 introduces a revamped full-screen gesture navigation system and new app open and close animations, with gestures such as swiping from either side edge of the display to go back, swiping up to go to the home screen, swiping up and holding to access Overview, swiping diagonally from a bottom corner of the screen to activate the Google Assistant, and swiping along the gesture bar at the bottom of the screen to switch apps. The use of an edge swiping gesture as a “Back” command was noted as potentially causing conflicts with apps that utilize sidebar menus and other functions accessible by swiping. An API can be used by apps to opt out of handling a back gesture within specific areas of the screen, a sensitivity control was added for adjusting the size of the target area to activate the gesture, and Google later stated that the drawer widget would support being “peeked” by long-pressing near the edge of the screen, and then swiped open. The traditional three-key navigation system used since Android “Honeycomb” remains supported as an option, along with the two-button “pill” style navigation introduced in Android 9.0 Pie.
