added text to the summary screen, commented out some seemingly incorrectly behavior (bug?) regarding the lastBatteryLevel (needs a fix by getting the batteryLevel from the lastSample (from the DB))
1. fixed two bugs (lastBatteryLevel was always zero, all fields of batteryDetails were always zero [incl. temperature, voltage, health, etc]) 2. diabled (commented out) storing/sending traffic info (for debugging purpose, since the samples were not stored locally (probably because of this condition:  if (! s.getBatteryState().equals(Unknown) && s.getBatteryLevel() >= 0)) {storesamples...} )
added a condition to skip the battery level check if this is the first time Carat is running
