It's contamination on the sensor, nothing you can do about it apart from get an exchange mate

Can I clear the sensor with something? Can Google exchange it? I've received my Nexus some day ago, and the problem there was since I use the camera for the first time... How much time I will stay without my phone?

Annoying app offering

Hi 2 everyone,
I have Xiaomi MI2S with MoKee ROM and found out that after every install (does NOT matter if its app, game etc.) this weird app-offer comes out at the bottom of the screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
...anyone has the idea whats that and how to get rid of it? Any ideas strongly appreciated!
Sincerely, JayM
PS: Has this thread to be placed in Xiaomi MI2S section? (or better to be there?)

Problem with snapchat

Hello, guys!
I have a Galaxy s4 mini LTE (GT-I9195) and last week I flashed AOKP ROM 7.1.1 Nightly (2017-03-26). But since I did it, snapchat doesn't work anymore. I've made a clean flash two times but the issue persists.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",

}
I saw some people having trouble with it, but they just can't log in. In my case, snapchat not even open.
(sorry my bad English)

No one? :C

Battery Spikes, hope is not going to explode!!

Hello, I have a little concern about behaviour of a battery for my lg g3 and hope is not going to EXPLODE!!
it is a huge 9600mAh , this one exactly https://tinyurl.com/y953s873 bought 2 weeks ago.
I notice from the battery usage graph it has some little spikes, see pic, and wondering if they are normal, anyone has seen them in the past?
Is safe to keep or it is an underlining of a problem??
