Just one app in ( whatsapp),The phone freezes for about 1 minutes if I want to exit to another App.I went to PEP store 15 Oct 2020,I got the most appalling attitude from a guy called Thato (rude and not willing to help). Telling me i bought pride not a phone that is why Iam not satisfied.And I was told that is how mobicel works(freezes and anyhow o must be content with it) and there is Nothing he can do as long as is not a technical issue.Was told of o wanted a better phone should have bought a R2000 upwards phone.And i asked if they have now become Pakistans you buy a phone you stuck with it.
