It's a good phone. Android 10 had already been patched with the necessary security patches.
Samsung Galaxy A51 Dual-SIM 128GB. A51 is an awesome mobile phone. I had a Samsung Galaxy A3 and it cannot compete with A51. There are a few additional features on the A51 as well as being the same size as the Samsung Galaxy S9+. This is the phone that I recommend to anyone looking for a decent, affordable smartphone. The phone is high quality, has less bloatware than usual, and the fingerprint scanner works very well, much better than the high end Sony phone.
