thanks. just updated. play with it for a while and notice a "kids mode" icon. is this new? sorry this is my 2nd spare phone so i hardly use it.
just to share, my fone is vanilla with only nova and swiftkey installed. the screen is at 100% brightness, sim card inserted but since the phone is at home mostly it is usually latched to my home wifi. i play with it only 10-15mins a day. the phone lasts for full 3 days and left around 10-20% batt. of cos no one uses his phone this way. but i reckon it should be able to easily pull through a day even with heavy usage (loaded with all necessary apps, that is.).
i also tested the 4G to 3G thingy. i'm on starhub. before making call, the line was 4G. during the call, it switched to 3G despite the fact that i remained still throughout the call. i read earlier about this Voice over LTE, but it doesn't bother me at all. my call still sounds intelligent to the listening party and there isn't a need for me to download anything in 4G
while making calls.
cheers.
