@oppo rubbish phone, rubbish customer service. My phone randomly overheated by using the same charger as always in less than a year. Covered under warranty but didn't work when I got back and now they have voided the warranty claiming its been dropped. #avoidoppo
I would be hugely massively grateful if any secondary maths teachers in England could please fill in this survey for my dissertation, and pass it on to other maths teachers they know. Thanks a lot!
