want better gps, buy hp with snapdragon processor

actually if u want cheap one, normally is xiaomi brand but as u say u use before xiaomi....

so u must check what is the previous processor u are using ...

if your old xiaomi hp is using snapdragon processor then u try other brand like huawei ....

if not then can try xiaomi note 8, less than 600, can check out in lazada or shopee
