I have the t-mobile s7 and tried to install Snapdragon Battery Guru but can't because, apparently the app is not compatible with my device. Is it possible I have a exynos chip? Can I find out if I do?

Hi
I'm new to this. I would appreciate any information on how to contact app companies to help promote their apps, i'm looking for smaller companies seeking for promotion.
Thanks.

My default notification keeps "ringing" every minute - my notification reminder is OFF. Also, I have turned my notifications off for ALL of my apps. Including messages and emails and it's still doing it. This is a Galaxy S7. I just got the phone yesterday. My husband got the same phone yesterday but his does not do this. Any suggestions?? It's driving me crazy!

All after Marshmallow Update:

1st - sketchy performance--drained battery causing boot loop

Then worked when plugged in AFTER a hard reset. Battery now fried (friend's battery worked fine).

Ordered new battery.

Next - got new battery & worked fine for a few days afterward

Intermittent freeze/audio glitches fixed by removing battery briefly, then worked perfectly for 12 hours

Awakened to audio cutting out, removed earbud jack and pushed back in helped

30 minutes later all mic/speaker/audio dead...not a single problem before installing Marshmallow Update from T-Mobile!

After the update to Marshmallow 6.0 I do not see the pictures of my contacts when making or receiving a call

Hi everyone. Just switched back to Android from Windows Phone. I have an LG G4 on AT&T. I don't want contacts from my Gmail account to sync to the phone--the only contacts I want are from an Exchange account I connected. I went into the Settings > Accounts area and unchecked to sync my Gmail contacts. In the Contacts app, I see the right list (just the Exchange contacts), but whenever I try to send a text message, I'm getting every contact, not just the Exchange ones. Is there a way to fix this?

I have the sony pc companion downloaded to my pc and have done a back-up on my battery-swelled Z3. I want to transfer everything to my Xperia S so I can get my Z3 repaired. I don´t have much (read: almost no) computer or smart phone skills so, please, baby steps please.

My new Samsung Galaxy S7 edge was giving me great battery life till today when in noticed the battery is dying much quicker than before. I looked in battery and found a process from android called 10265 that is using up a lot of my battery apparently even when the phone is off. It says right now 80%.

I wanted to post a screencapture but for some reason I can't. I hope someone can help!
