Hi, i've flashed a Volla22 with UT 20.04 OTA-4. Everything seems to work like expected, the only thing that's strange is dual-SIM functionality. On my Volla (yggdrasil) it's normal, that almost instantly after the lock screen is loaded both SIM-cards are ready and usable.
On the Volla22 it seems to take pretty long to detect the SIM-Cards. The card in slot2 seems to be detected faster and so cellular-data is switched from sim1 to sim2, which isn't working in focal. Sometimes sim1 isn't detected at all.
This is what i've already tested:
- Both cards in yggdrasil with OTA-4 -> works
- Only one SIM-card in mimameid (doesn't matter which slot and which card) -> works
- Both cards in mimameid with VollaOS -> works
- Both cards in mimameid with UT 16.04 / 20.04 -> doesn't work / gamble
So my question is: Does somebody use a Volla22 with two SIM-Cards and it's working like intended?
