I installed it with PixelOS 18 Feb 25 build.  All was good.<\/p>\n\n\n\n<p>In June, I upgraded to the last build for Android 15, 10 Apr 25.  After some days, I noticed that I keep missing WhatsApp calls.  Some apps eg Forest with power savings disabled was sleeping.  Runkeeper is lagging when tracking my runs.<\/p>\n\n\n\n<p>The new version with its aggressive power savings may not be a good thing and I have decided to down grade to the older Feb version.  The rule of thumb doing this is dirty flash upgrade, but clean flash downgrade.<\/p>\n\n\n\n<p>I thought I try an experiment with dirty flash downgrade.  Unfortunately, it would not boot.  Clearing the cache gave the same result.  In the end, I have to clean flash to get it to boot.<\/p>\n\n\n\n<p>Nice things about the 10 Apr build is the combined quick setting buttons for Do Not Disturb in the Modes button.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.alfredivy.sg\/blogger\/2025\/02\/upgrading-to-android-15-qpr1\/\" data-type=\"link\" data-id=\"https:\/\/www.alfredivy.sg\/blogger\/2025\/02\/upgrading-to-android-15-qpr1\/\" target=\"_blank\" rel=\"noreferrer noopener\">link<\/a><\/p>\n\n\n\n<p>Update 23 Aug 25<\/p>\n\n\n\n<p>After the downgrade, I noticed when 2 SIMS are inserted, I can&#8217;t get data.  In JB, TPG performance was unstable.  I have to use my Poco M3 as a Wifi hotspot.  A real buzz kill.  <\/p>\n\n\n\n<p>1 Sep 25<\/p>\n\n\n\n<p>The TPG&#8217;s APN was named wrongly.  It was set as SIMBA instead of TPG.  Perhaps this was the cause of the performance issues.  The no data when 2 SIMs was a user problem, me.  The slide to enable Mobile data doesn&#8217;t work for dual SIMs, I have to scroll down to &#8220;Your Primary SIMs&#8221; to  select the Mobile data and choose which SIM to use.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Downgrading my Android phone custom rom.
