No it doesn't Dex Support
Services and Applications
Yes, you're right. I tried connecting a S10 lite with a Dock and nothing happened. Later on when I googled I saw this post. Hence, Samsung Dex isn't supported by S10 lite. It is however, supported by S9.
Yes unfortunatly the Lite devices currently cant support DEX. This poentially could become available although no confirmed rollout plans are available for this device. However we havent ever retro fitted a device with DEX so possibly not the device to look for. The S10 could be the right device for you. If you would like further information on this device im happy to help.
I already bought a Note 10 lite thinking it had Dex.
I guess I did not read the fine print before purchasing.
I thought I already gathered enough information, but rarely reviews mentioned the Dex part.
I'm looking to buy this device too. I think it's a very good idea to add DeX support to this device as its hardware is very much capable. Maybe not soon but please keep it in mind.
