Unresolved Printer Missing Spots during print

Hello,
I'm 15 and not that experienced with 3D printing so stay with me if I don't make sense. I am trying to 3D print an iPhone case and my printer misses spots, I believe the x axis moves too far and skips an area. If anyone has any suggestions to how I could fix this problem it would mean a lot. Thanks!!!
The picture I included is a print that should be solid.

 

It's all over

 

I am not sure what I am looking at either but here is a stab:
Are you talking about the diagonal infill lines? If so try increasing your number of solid bottom layers, assuming that is the bottom. Also you can change the infill pattern.

 

I think that's right. I'll check on that. Sorry I'm not to educated with my printer but I'll try to look deeper to figure it out

 

Just a note, the extra "noticeable" infill lines. I use to get those, back in the beginning, if I had my first layer way to thin. The extruder kinda stops momentarily, and lays a supper thin line, until the pressure builds up then starts again. Once it hits the second or third layer it would be supper smooth and print perfectly but the bottom side would have those types of marks due to the density difference. Just something else to check, hope it helps.

You may need to adjust your z-offset (raise the nozzle) that would explain the thin line and choking.
