I am trying to solve a problem on my Tab S2 8" (SM-T713). I am finding that many of the apps currently on Play Store warn that "This app may not be optimised for your device". There is no further explanation provided. I have several such apps installed on my S2 and I am not aware of any problems. Can anyone shed any light on this? I am wondering if it is related to the launcher being used. In my case, that is Nova. Any thoughts? BTW, I have tried to resolve this by asking the question on a couple of forums - to no avail.

Hi Folks...I was just looking in Settings > Apps > Device Maintenance > Battery. To my great surprise, it indicated 19% usage since the last full charge, which would have been yesterday evening. Other apps are typically between 0% and 2% battery usage. Since the last full charge, I may have manually run Device Maintenance once. I'd be very interested in knowing what other Tab S2 users see on their devices. My S2 is the SM-T713 running Android 7.0. Any feedback most welcome.

Hello Everyone? I have just joined this community. One topic that greatly interests me is the use of heart rate variability (HRV) as a biomarker for assessing a person's state of wellbeing. I am looking forward to spending some time here.

Hi Folks!

I have three questions for all you Tab S2 owners:

(1) Which Tab S2 model number(s) do you own? These are the SM-Txxx numbers that you can get from Settings > About Device.

(2) Have you updated to Android 7 (Nougat) and, if so, have you had any problems after the update?

(3) Which version of Android were you running before the update?

I am trying to see if any update problems that I've read about on the internet are related to specific model numbers.

Thanks!

Really pleased to have discovered your site and app. Interested in the spectrograph (spectrometer). Please tell me more.

I'm delighted to have just joined this forum. I have a Tab S2 8.0 and my wife has the 9.7 version. We have both had the Nougat update notification but we're hesitant about going ahead with this. Nougat doesn't appear to have much to offer over Marshmallow. I'm also an avid user of GSam Battery Monitor but it seems that Nougat bundles all apps together. So, it is not possible to track down individual apps that may be draining the battery. BTW, I'm in the UK.

I really like these backgrounds but why do they appear on my lock screen? Is there a way of changing this? I have a Nexus 5 and use Nova Launcher. I realize that it doesn't have an Amoled display. Other than that, keep up the good work!

I am hoping that I can solve a problem that I have aleady reported by email. I am currently using version 3.8.4. I find that HRV frequently drops to 1 when doing both Morning Readiness and Open Readings. But this does not get recorded on the Intra-Reading Chart.
