poor performance on GPS hardware and fixing some obscure code

Components

GPS logger is a lightweight, efficient battery application. The purpose of this app is to record your GPS coordinates to the SD card at specified intervals. This app runs in the background so you can go for a walk, hike, ride a plane or photo session or even travel buy stuff with this app running for as long as possible. Once you get back on your computer, you can use a file to place a photo on, upload to a travel site

Proposal

my proposal has a bad performance on the GPS hardware, for some reason, besides slow GPS locking, it is also inaccurate, sometimes even misleading. To compare I will use i747A + logger, a bluetooth GPS capable of recording tracks.
and very much the code codes do not clearly appear when entering the application
very difficult to understand by new users install this app,

Mockups / Examples

try to see the result of recording tracks done Android that I use.
this is the first mistake I experienced on the android GPS logger

The second mistake I experienced.
About code code when entering the application, code is very much that can not be understood

make the first gps look when entering an application like my example below, to make it easier to understand and not much code code that exists when entering the application

Benefits

has poor performance on its GPS hardware, and is slow when locking GPS,
and lots of code codes that are not clear when signing in apps,
and change the first gps view the first time you sign in to the app, so users are easier to use
