Galaxy S20 OTG SD reader compatibility

I have an older generation USB C OTG SD Card adapter from Anker and my S20+ will only “charge external device”. Does anyone else have this experience? Do the new release adapters work with the S20? Android appears unable to switch host control from device to phone and does not recognize any SD or micro SD card inserted. Adapter issue or phone issue?

Hey @jbraeckel
I had odd problems with my S20+ and “another” brand of reader.
When i plugged my reader in (with SD card inserted) i had a silent notofication.
I had to swipe down, press the notification and change the settings.
Mine works now, give this a try if you haven’t already.
