MarkG<p>I got some call from a random number. It was a guy who claimed my number had dialed him. I assured him I had made no such call. He didn't believe me. He felt I was a telemarketer, and as such, invited me to meet him so I could get the "beating I deserve". I politely declined his offer and bid him adieu.</p><p>But, I share his displeasure with telemarketers. And I note that frequently they come from what appears to be local numbers, even if it's clearly from an overseas caller. So, I do wonder if my number was actually portrayed by a telemarketer to this gentleman. Does anyone know how such a thing may work? And what can be done to prevent such a possibility?</p><p>I checked my phone's settings, and found that my phone is encrypted. But, I also found, under "credential storage", that a whack of oddball entities are listed as having "trusted credentials" (see image -- it goes on much longer than the screenshot). Anyone else have a similar list? I note there is the option to "clear credentials", but I don't know if this is wise to do.</p><p>I use LineageOS 22.2 (Android 15).</p><p><a href="https://mindly.social/tags/tech" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tech</span></a> <a href="https://mindly.social/tags/android" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>android</span></a> <a href="https://mindly.social/tags/lineage" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>lineage</span></a> <a href="https://mindly.social/tags/credentialmanagement" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>credentialmanagement</span></a> <a href="https://mindly.social/tags/telemarketers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>telemarketers</span></a> <a href="https://mindly.social/tags/phone" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>phone</span></a> <a href="https://mindly.social/tags/Mobiles" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Mobiles</span></a></p>
