I found myself needing an Android phone because I could hack Android Auto onto my car's infotainment system (mazda 3) which is obviously useless without an Android phone. I'm an iPhone user so wanted to spend as little as possible on a device without it being unbearably slow and too low on internal memory. A difficult ask.
Yesterday I went to Argos as I'm an impatient bugger, and picked up at first an Alba 4, it didn't even get to the choose wifi network screen on setup, just sat at the 'just a sec' screen for 2 hours. Good start, already finding Android to be a thorn in my side. Sent it back, didn't have another in stock, so they exchanged it for a Alcatel, or something. Turned out after I powered it on it had 4GB less internal storage than the previous choice, it was also terribly slow, the screen felt crap, and in the end I decided this phone was not worth £25, let alone £50 so back that went too.
Being slightly more patient as I have Amazon prime I ordered a Blackview A7 for £52.99 from Amazon. I think I finally made a good choice.

For what I will use it for, which is basically, tethering data off my iPhone to run Android Auto with Google Maps/Waze/Google Play Music/Spotify & radio apps, it does the job. It would probably do social media fine as well. Camera is ok, has headphone jack, 2 sim card slots and can take micro sd to 32GB which I'd suggest you put something in there if you made it your daily phone.
Downsides: It's 3G only, but I'm not using a SIM in it, so I don't care. Seems you can move almost nothing to the SD card app wise. I have about 3GB free still after installing all the above. Android still seems too 'faffy' and while I can see the appeal for some, it's not for me.
If you're after a mega cheap phone and won't install loads of apps and don't need loads of internal storage space it's worth a look, and with distance selling regs or whatever it's called these days, if you don't like it before 14 days, just send it back!
Of course if you have a bit more patience than me, you can probably still get something even better for £50 if you're prepared to order from China!
