browsing thru xiaomi bbs forum and saw the lens focus issue again.
this guy's yicam having the issue and he tweak the lens manually.

you can see the comparison pic he taken before and after tweak and compare to gopro4(silve)

[attachmentid=4499214]
[attachmentid=4499216]

order: before tweak , after tweak, gopro4
[attachmentid=4499217]

i see quite an improvement from his picture.
anyone tried to capture a picture with near, middle and far item to focus. like the flower pot, the trees and the building in the pic above.
then see got this issue or not 

sos

hows the sound / mic performance when covered with the waterproof casing guy ?

Anyone willing to make tutorial?
I can't read Chinese.

not good. almost not any sound will be recorded.
if you wan sound and video better not put ur cam in waterproof casing

i c... same as SJCAM also..  thx God im not order it yet... hmm better funding for GPH3 then.. 

dude even GPH3 if u put inside their waterproof casing your not getting much sound as well
thx God for wat 

i used GPH3 and sound is fine with the casing...

u mean the tweaking of the lens?  i can make the tutorial when im free la.
but ur cam got focusing issue? 

I think so. Most of the early batch got this problem right?

guys, my yi cam battery seems drained even I didn't use it. Noticed this since updated to FW 1.1.0
Anyone here experience the same issue ?

this is a known issue. alot user reported battery drain
only hope firmware update can solved this

but i think theres a tweak some user did to stop the leak. u have to search back previous post.

another way is take out the battery when not in use

Not sure if I should get it    Able to get for RM199 today at lazada.

hmm. i've seen review testing the sound using GPH3 & 4 with waterproof casing ,
the sound seems muffled, and if  wan decent sound need to use the casing with cutout behind.

are you using the cutout casing ?

anyone notice this setting?
