@johndoe Thank you for your response! I believe I found one nearby, now

To complete this thread: I found a mouse that works like a charm: Rapoo Wireless Mouse MT750S Okay, the lomiri bug that it only works fine in portrait mode is there, but I'm sure this will be fixed and this has nothing to do with the mouse itself. So, thanks for all suggestions!

@MrT10001 Found it. It's the Sapot browser - don't know why. Every other app gives sufficient sound, including the Morph browser. "Man findet es immer da, wo man zuletzt sucht" - German saying, meaning "you always find it where you are looking last" (deepl). Thanks again.

@rubencarneiro Thank you. I had changed my USB ports, USB cables, PC and so on and was stumped why this issue was occurring. What I did see with the installer it went really, really quickly from fastboot to fastbootd and did the partition resize so quickly I just saw a flash on the screen. When I do it the manual way, it is quick but visible.
