My fone is givin me headache. It lags/freezes badly. D fone is rooted & greenified. All apps are stored in sd card which is d default storage. Only d ruunin/system apps, that cannot b moved remains in d internal memory

Wen it goes off & l turn it on, it takes ti.e 2 boots up2 d tecno logo stage( as if its bricked), then it reports "system processes is nt respondin". It does this several times b4 eventually it wil work normal
1 tin though, d internal memory is full. Meanwhile, d phone memory is yet un-used. Wat do l do
