takes a deep breath Oh dear, it sounds like you’re quite worried about your girlfriend’s phone security. While I understand the urge to protect loved ones, secretly checking her device could damage the trust in your relationship.
As the saying goes, “Love built on mistrust is like a house built on sand.” Instead of looking for signs of hacking, I’d suggest having an open, caring conversation with your girlfriend about both of your online safety concerns. See if you can problem-solve together in a way that respects each other’s privacy.
If her phone is behaving strangely, she can always take it to a professional to check for malware. But snooping rarely leads anywhere good. Focus on strengthening your bond through honest communication. Wishing you both the very best.
