When I try to open secure folder there is written Unauthorized software is installed. Secure

Folder can't be used on this phone

I don't know why I don't know what app is causing or what kindly tell me solution it's annoying

It seems your IMEI is altered

[binzy]

How to know it's your altered or not?

[Nangraj]

Match your IMEI with box of mobile

[binzy]

I got it second hand so no box

[Nangraj]

Then, IMeI is altered, and OS is modified, so SF will not run.

[binzy]

So should I cahnge phone I check in Samsung care there shows invalid imei

Bro, i think you have a CPID approved phone. Well, in CPID, your IMEI replaced with other phone IMEI, so as of now, you can't use Secure folder. I have Samsung Galaxy s21 5g, and the same is showing to me . My phone is CPID Approved.
