In reply to ksjs: I am an Android app developer and you really got me thinking if it was possible to get a decent phone for 50 quid. I was doubtful.
The only phone I could find to recommend was a htc desire but it had a fairly bit scratch on the screen. I had this phone for 2 years and it was great I just sold mine for 100€.
There are lots of cheap phones from brands that I have never heard of. In my experience these never work well.
I would suggest you up your budget to 75 pounds or a little cheaper and get a phone that is going to work well. Otherwise save your money and keep your feature phone.
If you was going to up your budget then you could get these...
- A good condition htc desire.
- HTC Legend. Similar to the desire but slightly smaller and slightly lower specs.
- Nexus 1 - googles own phone (google make android) . Its pure android which means the manufacturer of the phone don't play around with the operating system. Which is good in my opinion. Pretty good specs as well.
Its worth noting that you can use customised android version which are freely available on the internet and greatly improve the performance and battery life tho sometimes you sacrifice stability. Tho to do that you would have to be a little techy or no somebody who is
