Ambient Light Sensor Problem


Recommended Posts

i've flashed my ZTE Blade with Japanese Jellyfish RLS6.

however, i can't make the ambient light sensor working as before

i tried to flash the fibblesan's r6 ROM, but the sensor's still not working

i've just noticed that the sensor doens't gv values (with all the sensor test apps) until i used that function recently

i dun know when the problem rises cuz i didn't use the light sensor at all (not even auto backlight)

is it because of the problem of 2.2 ROMs of this phone or a hardware problem?

It is with 2.2 roms.

But the light sensor does seem to work on JapJelly.. Sort of.

The menu backlight illuminates in low light although auto brightness doesn't seem to work

Auto brightness works for me. (JJ RLS5)

Once it starts working, it works, but after a reboot it stops.

Messing around with the sensor tests (*ZTE*0#) or starting an app that uses the light sensor seems to fix it.

In the first couple of minutes it works oddly, it reports indoors 0 SI lux, but in complete darkness (sensor covered) it reports ~16 SI lux,

but then it recalibrates itself, and works perfectly.

but i can't even enter the ZTE test page (*983*0#) with Jap Jellyfish

it gives no value both under daylight or in complete darkness for Jellyfish and fibblesan's R6

are they using the same kernel? will the kernel be the source of trouble?

Enable it first with *ZTE*OPENEM#

For me, on Jellyfish, Auto brightness does work in that it makes the screen brighter in bright light. Where it seems to have a problem is that the minimum value it will dim the screen to is higher than what the screen is capable of dimming to.

the diagnosis page works, thx !!!

but the proximity sensor and light sensor in the sensor test page showed "failed"

the proximity sensor was working just before and i'm sure of that coz the proximity lock was working in this afternoon. but it seems the proximity sensor also failed working ....

now the phone is restarting... hope it will be ok ....

wt's going on?? ..... :D

Sorry for abusing this topic, but is there a way to regulate brightness so that the display gets much darker? to me it is to bright even on the lowest setting.

next step would be a customized adaption of the brightnessregulation via the sensor -possible?

Possibly the light sensor/proximity sensor might need tweaking - see here on xda's forum.
