Question

I tried every thing even went to Apple on the phone but it did not crash for four days on 6.1.3 now crashing again it crashes because of LOW MEMORY that what it says on diagnostic and usage on all apps plus I only got 8 apps on it and still got 53 GB left on it it in $59.00 rubberized protection case always on my bed never leaves the house it so protected it looks brand new now for $400.00 electronic gadget I assume it would be better than this when it was 5.0 it work fine I even had music on it 7,000 songs worked fine but took off all music just using for photos and 8 apps even my iPhone is crappie my Android S3 is way better than both of my Apple gadgets I notice Apple last only 3 months then you got to re-sync to computer every three or four months for all the money you pay their products they are all ways breaking down the only thing that really works well is their iPod 140 GB which I have also and 8 GB which didn't work after three months but they are good for music and photo taking though every thing else just crappie I think I have bought over $3,000.00 in iPods in four years from the Apple store

Answer 1

Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.

- Restore from backup. See:                                 
iOS: How to back up           
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
