best phones under 20k are the old lg phones. snapdragon 865 for 10k during lazada/shopee discounts 7/7 etc . their snap 845 is only 5k php both are already using oled screen . honestly if you are just playing mobile legends its good enough. genshin/ hsr will struggle abit on snap 845 but you can choose 6gb ram to make it better and just play ln low.
ps... DONT EVER EVER CHOOSE HUAWEI.
