I use 6.1t android on samsung S4 with internal barometer.
the indications of the variometer are crazy and announce fast values #8203;#8203;like: +3.0 -2.0 -2.0 +1.0 without moving.
now the values #8203;#8203;after the comma are gone.
if I put myself in the shelter of the GPS network, the vario that previously worked with the internal barometer remains fixed.
if I change with barometer values, the variometer remains stopped.
before, when I moved slowly up or down it indicated +0.1 or -0.1, now it's stopped.

Sorry,
I can not reproduce this. Tested on a Nokia8. I get Vario changes in 0.1m/s steps. Did you get the Message "USING BARO ALTITUDE" ?
But please be aware that smartphone Baro Sensors are not a good vario sources!!!
If there is no valid GPS The display (and vario) is not refreshed. I doubt it was different in former versions.
However it is planed to go to a higher screen refeshrate (10Hz) on the way towards Version 8 of LK8000.

I did tests on different devices and here are the results:
Samsung S4 android 5.0.1 with built-in baro apk 6.1t:
vario baro: NO
vario gps: only big values.
Samsung S3 android 4.4.4 with built-in baro apk 6.1h:
vario baro: NO
Vario GPS: YES all small values.
LENOVO TB3 android 5.0.1 no built-in baro apk 6.1r:
Vario GPS: YES all small values.
HUAWEI honor 5X android 5.0.1 no built-in baro apk 6.1t:
vario gps: only big values.
HUAWEI P8 Lite android 5.0.1 no built-in baro 6.1t apk:
Vario GPS: YES all small values.
MIO PNA no built-in baro apk 6.1j:
Vario GPS YES all small values.
V2 Pna with baro "gliders guides":
vario baro: YES even without altitude GPS even without GPS reception.
It seems to me that the proper functioning depends on the devices.
After stealing years without baro on my V2, I made the difference after the installation of the baro that improves the accuracy of the calculation of glide, the orbiter and I think it is particularly important to associate with calculations.

Maybe a rounding or unit problem,
what units are you using for the vertical speed on Config Page 9 (m/s, ft/min or knots)?

Of course it does, but it is still not as good as real variometer. http://www.postfrontal.com/forum/topic.asp?TOPIC_ID=8863
