Problems with my device

[Lugulbanda]

hi i have issues with my device, last year i did the update, everything looks ok that time, then i got ill and as i was otw to my health center i tryed a few measurements, but all were very strange, first i regotniced the blue flash didnt appear and the green light also not appered, so i took out the SD Card reseted the device, and restarted it again, but with not much effort, i drove 5 hours, and collected 2k Data, wich cant be, i did a few measurements in the City i was in the hospital, but also not much measurments, today i traveled back and again i got nearly no measurments, and strangely a full measurement set from 10AM to 2 PM on drive 41503 was completly missing, and i shut down the device as i arrived at home at 2pm, i have no idea whats wrong with my device but the issues make all measurements nearly meaningless.. :( pls help

i remember i saw in the past a blue flash from time to time on the sd card, atm tho only thing that flashes is the red counter LED, and from time to time the FIX LED on the GPS, but no longer the blue flash from the SD Card, the log alarm light comes sometimes and is mostly off, if i start the device, i see thr right green and blue led on the SD card flashing, and th GPS is blinking Red, if i remember the past the green log light was allways on, now its sometimes on mostly not and the blue light from the SD Card is allways off.
