[GUIDA] aumentare luminosità massima nelle ROM scure

[mattedrift93]

ciao a tutti ! oggi ho trovato un'interessante guida su XDA su come aumentare la luminosità nelle ROM che c'è l'hanno bassa ! nel mio caso l'ho testata sulla SlimBean Build 6 ecco il link CyanogenMod brightness Issue FIXED - xda-developers mi limito a tradurla :

-dopo aver flashato la cyanogenmod installare root explorer (io ho usato root browser)
-recarsi nella cartella system/etc - e cercate nella directory della cartella "etc"
-il file "hw_config.sh"
-aprirlo come file testo
-scorrete giù fino a leggere queste righe di testo :

# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current

e cambiate i valori sottolineati con questi

# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 0,0,0,0,0,0,0 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current

riavviate e avrete risolto il fastidioso problema della luminosità bassa

ottimo grazie 1000. io l'ho provata con la pac rom 4.1.2 e funziona alla grande

Ma da me quel file è diverso,solo alcune cose sono simili,come fare?

ecco cosa dice a me quando apro hw_config:
# Vibrator configuration
dev=/sys/devices/platform/msm_pmic_vibrator
echo 2400 > $dev/voltage_mv

# lm3530 LMU configuration
dev=/sys/devices/platform/i2c-adapter/i2c-0/0-0036
if [ ! -f $dev ];
then
dev=/sys/devices/i2c-0/0-0036
fi

cosa devo modificare?vale per tutti gli smartphone questa guida?

Risolto basta scaricare da xda il file increase_brightness sta al post numero 4,(Cyanogen Mod Low Brightness - xda-developers andate nella cartella system,etc e copiatevi il file hw_config,e poi vi cancellate(tramite software che vi permetta di entrare nel sistema android del vostro smartphone,tipo android commander)il file hw _config del vostro smartphone,e incollate il nuovo file scaricato.
Sul mio xperia x 10 mini con cm 10 ho risolto cosi'.
