Light out while sleeping please

Most annoying light keeps coming on when I move in the night. It wakes me up
Also need brightness adjuster as it’s too dim in the sunlight

Don't waste your money

Jolt band is worse than useless. Took 48hrs to charge, & 3 to go flat. Steps inaccurate, way higher than I actually did (& recorded on pedometer). Band turns off after a couple of minutes & won't turn on again unless connected to charger, tried to calibrate for the "turn wrist to activate screen" feature to see if it helped, just kept telling me to tighten the band which could go no tighter - no room to write all the rubbish things about this! App has nice interface, shame there's no data to sync on it.

Please return your device if you can!!

Worst quality, inaccurate tracking footstep as well as distance. Notice when you have a phone??? Its like 3am it will wake you up by vibration without any phone call or text messages. Sleep record??? Extremely useless, the last using day before i chucked in the bin, its show 7hrs of sleeping although i have slept for 9hrs??? Please use your money wisely, if you want something help with your walking or jogging, get a wellknown or expensive brand, this product maybe just for trial, LOL.
