Overview
The BLU Studio Mini 2023 (model ST1020T) is a very budget device distributed by Assurance Wireless, through the Lifeline Assistance program.
The device has the following core specs:
- Mediatek Helio A22 CPU
- PowerVR GE6300 GPU
- 2 GB LPDDR3 RAM
- 32 GB eMMC
- 960x480 60 Hz TN display
- Wi-Fi 4 (802.11n 5 GHz) and Bluetooth 5.0
The specs are nothing to write home about, but it does deliver Android 12 Go Edition with up-to-date security patches (it has March's Android security update at the time of writing) and no bloatware to speak of, only including core Android apps and a fairly complete suite of Google apps (Play Store, Photos, Files, Messages, News, etc.)
