xperia Z1 compact problems

[sr27]

Phone has developed various problems.

1. Cannot send texts. Screen feezes after typing a few words.

2. Cannot open Settings. White screen frozen, then message: Settings is not responding. Sometimes the screen just goes black and I have to turn the phone off and back on again.

3. Google app - takes around 7 or 8 seconds for Google to appear on screen. When typing into search box, it says it's failed.

Only 1 app has been installed from new - Good Morning - which has now been uninstalled.

Unused memory on SD card is 2.47Gb.
