for those that asking gps issue. my 1A don hv this problem, lock immediately. slightly fasster a bit compare with my redmi note 4. both actually also work well in gps.
1 night using experience :
gps ok
battery not as strong as rn4, due to small battery ? battery 1 midnight drop 10% in my case with data and wifi on and connected to wifi. that time was insert with dual sim card.
this morning take out 1 sim card and will see the battery result from that, battery charge back to 100% at 630am. see how it last tonight.
camara ok , slightly better then rn4. for this price range. i consider it as 1 of the value buy already. good job xiaomi.
an pure android with sd card support , i always dream with, as previously my nexus phone no sd card de.
sound / speaker i rate same as rn4
speed, well, of cos is fast. ram usage average 2.4g out of 3.5g, total 46 apps installed.
what i missed :
no dual apps , cant hv 2 whatsapp.
panel icon cant customize. with to have a short cut key to on off the sound .
what i gain : split screen. but unlikely will use as ince split, both screen is so small for a 5.5".
previously use rn4 avarage make 1 hours plus of phone call everyday. lets see how this phone last today. now already makes 30+ min call.
