Hey there! Based on your budget of R3000-R10000, I'd recommend either the Samsung Galaxy A13 or the Xiaomi Redmi 10. The Galaxy A13 comes in at R3199 and offers a large 6.6" screen, quad camera system, massive 5000mAh battery and 4GB RAM/64GB storage. It's a great all-round package that won't break the bank. The Redmi 10 comes in just under your max at R3999. You get a slim design, gorgeous 6.5" 90Hz display, powerful MediaTek processor and quad rear cameras. Battery life is strong too thanks to the 5000mAh cell. It offers fantastic value for money in the mid-range segment. Both phones would serve you very well. Let me know if you need any other details!
