Samsung phone Huawei Nova 3a

Hello I have two devices that I've had for a while, but they are working perfectly, in sha Allah. The Huawei Nova 3a has 64GB and works perfectly, except there's an issue in the middle of the phone that doesn't press properly, which I highlighted in the picture with a red line. And the Samsung has 8GB storage, it has some scratches, but all are on the anti-break screen protector, and there's only a minor scratch reaching the main screen, but it doesn't affect usage. The back cover has several cracks, as shown in the pictures, and the battery doesn't last very long. The two devices come without accessories. I want 350 for both, negotiable. I accept exchange for something suitable
