Show HN: 디스플레이가 깨진 Samsung Galaxy S7 사용자를 위한 팁

In 2016, I decided to spend about $800 (€700) on an upper mid-range phone for that time: the Samsung Galaxy S7. Years later, I replaced the battery with one bought on AliExpress, and it didn’t satisfy me. I also dropped the phone and replaced the screen simply because I was attached to that model—it felt much higher quality to the touch than more modern devices. I wanted it like when I first bought it: pristine. I promised myself I’d use a case and replaced its “Super AMOLED” screen. This replacement didn’t satisfy me either. It was done at an out-of-warranty repair service, and the screen quality wasn’t the same as the original. Moreover, this process caused the battery to move around inside the phone.
My son dropped the S7 a second time. That case didn’t live up to its promise. I had backups of the data, but something still left me unsatisfied—I couldn’t go through a proper “mourning” for its sudden, total screen failure. But I decided it was time to move on.
A couple of years later, I saw it in a drawer in my man cave while doing a general cleanup, and that feeling of not having been able to say goodbye came back strongly. I retrieved it and, carefully and under supervision, started charging it. The battery didn’t overheat too much or swell. I told myself, “I’ll take one last look at that stupid Mr. Robot wallpaper before taking it to recycling.” I immediately thought of scrcpy. I downloaded the ADB app pack—somewhat uneasily due to cybersecurity concerns—and connected the S7 to my Windows 10 machine. For some reason, USB debugging wasn’t enabled. That’s when my problems began.
I won’t go into the details of the (at least) 6 hours spread over 3 weeks. Instead, I’ll say what didn’t work and what strategy finally let me take one last look at the home screen of an S7 with a completely black display.<p>What didn’t work:</p><p>Disassembling the phone to try to fix the digitizer.</p><p>Following advice from chatgpt.com claiming the S7 was compatible with micro-USB to HDMI adapters.</p><p>Following “blind navigation” advice from chatgpt.com.</p><p>Believing that if it’s not on Reddit, it probably can’t be done.</p><p>Believing statements from chatgpt.com like “the Samsung S7 didn’t have keyboard shortcuts like the one you’re asking for.”</p><p>Not realizing how overwhelmingly present and invasive Google is in Android settings (basically, everything leads to Google).</p><p>Assuming the entire screen was still touch-responsive.</p><p>Using a non-backlit keyboard via the micro-USB port, which gave no indication if it disconnected from the smartphone.</p><p>Thinking there were no meaningful differences between information sources (US vs EU) and between Android versions.</p><p>And finally, the most concerning one—which may hint at what I ultimately did: believing big tech makes things easy for people with sensory disabilities, especially those with visual impairments.</p><p>What did work:</p><p>Extrapolating methods from other manufacturers like OnePlus.</p><p>Watching many YouTube videos.</p><p>Being humble and accepting that some strategies don’t work, no matter how many hours you spend on them.</p><p>Having a TV with screen sharing.</p><p>TL;DR:</p><p>Press volume up and down to activate TalkBack.</p><p>Press Windows + Q to open the top options menu.</p><p>Navigate to SmartView.</p><p>Double-tap the available device description while my LG TV was in screen-sharing listening mode.
