DEX died after ADB Bloatware Removal


Oct 19, 2021

I decided to debloat my Samsung Note 20 Ultra phone of all the bloatware apps Samsung installs. I used the Android Debug Bridge (ADB) shell to perform this bloatware removal and the list shown below identifies all the Samsung bloatware app names which I used as a guide in my removal process.

Everything went perfectly except for the fact I mistakenly uninstalled DEX which is an app that allows me to connect my Note 20 Ultra to a monitor via an HDMI connection. Once the connection is established DEX would automatically start and magically generate a "Windows Like" desktop GUI on the monitor. In short, my DEX is no longer working in the same way it was working before I performed the debloat process.

I hope somebody in this community can identify to me which Samsung parent app from the list shown below is the DEX app subordinate to? Because my theory is the DEX app is hiding inside one of the parent apps shown below and what is not making it easy is how the word "DEX" is nowhere to be seen. Therefore, I hope somebody can tell me which of the Samsung apps shown below I should leave untouched so my DEX app remains operational.

Any tips welcome.

Thank you for the post Unforgiven. That is funny, I too was thinking the Smart Things app has a high probability of being the parent app for DEX. I'm no expert either, and Google has not been able to confirm to me that the Smart Things app actually is the one app I need to leave alone if I want my DEX not to break.

Unless somebody in this community can tell me with 100% certainty the only option I have left is to do a factory reset on my Note 20 phone and then uninstall everything again except for the Smart Things app. I wanted to avoid such guessing but maybe this is the only recourse I got left.

I'm still stuck. Can anybody in this forum community offer any insight into this problem?

Think you might be looking at the nuclear options there, of a factory reset, or even re-flashing the original Samsung firmware.

Of course I'm not deleting anything else off my Note20, other than the third-party bloat apps I've already deleted, and disabling Bixby.
