General aviation pilot reported a NMAC at night during approach requiring evasive action to avoid a collision.

Narrative

While conducting a personal night flight to maintain currency and proficiency; I was preparing to turn inbound for the ZZZ Airport on a heading of roughly 330 at 3500' MSL approximately 5 miles north of ZZZ. In my scan outside I suddenly observed a solid red position light moving rapidly toward me from behind my right door/windshield pillar in my aircraft. I immediately put my aircraft into a right bank to attempt to turn behind the oncoming aircraft. My landing light; position light; beacon/strobe were on for the entire flight. The oncoming aircraft was illuminated by my landing light as it crossed from right to left in front of me and continued behind me as I rolled wings level.My aircraft is equipped with ADSB-out and a Mode C transponder and is normally equipped with ADSB-IN traffic through the Garmin Pilot app on my tablet through my GDL 39 receiver. I was attempting to use Garmin Pilot on my backup tablet for this flight as my primary tablet had a dead battery but Garmin 'software locked' my app and rendered my device useless since my subscription was renewed last month but my device has not been connected to the internet since the subscription renewal. This near miss could have easily been no factor at all had my ADSB-In information been displayed. I was able to set up my phone to communicate with the GDL 39 later in flight to capture the tail number of the Piper Lance aircraft believed to be encountered. In summary; I believe the oncoming aircraft approached from a blind spot behind my door pillar. I do not know if the other pilot conducted any evasive action to miss my aircraft or if the other pilot ever saw me at all. Had evasive action not taken place; there would have without a doubt been a midair collision. Looking back; I do wish that I would have also added nose down pitch with my right bank to get below the other aircraft. ADSB-In traffic would have prevented the near miss altogether.
