I have an old nexus one which is fine for me. I actually only use it to run 4 Bible study apps. I don't use it as a phone or to check mail etc. It has always worked fine until recently. Now I get a message telling me that '....it has stopped unexpectedly'. If I delete it and go into google play store to re load it, it tells me that i do not have enough storage. I have google play services taking 88.45MB and google play store taking 22.73MB. What is the difference and can I delete google play services. I download the 4 apps from google play. I know my device is old but I love it. Help please
