I use a Samsung S6 Edge at present . Still a decent phone. Wish I had gone for the Realme 8/128 for £109 but will see if Xiaomi come up with a decent cheap offer.
Funnily enough I decided to get it ordered, I have an ageing but mint condition Samsung S6 which is but lacking USB c and card slot, and an old rooted LG G pad, the Redmi can really replace both and I'll probably get the 69 back selling the old ones I had the Willey Fox Swift ages ago, they were buggy but cool phones, no good today though
Be careful with the voucher. It was suggested they last 4 weeks but mine disappeared after 2 whilst I was dithering on what to buy. Got another but still undecided lol.
I can still get the redmi 9 at 69 as the voucher is still on my account, still haven't decided whether to or not yet
had a wiley fox couple of years ago, nothing but problems, didnt even get a year out of it
