With all the drugs-related violence, I’d be happy to just have a heart rhythm in Mexico…
And believe it or not, I have lived my close to 40 years in Mexico, never had anything stolen and my family hasn't either had any issue, never seen anyone firing a gun (fingers crossed it continues like that).

Fortunately, unlike the mass shootings in other regions, the drug related violence in mostly between the competing cartels, but it does take innocent lives and bystanders as well. Worst part is that the government doesn't even acknowledge it as a problem - so it is not looking like will get better any time soon.

8.5 resulted in noticeably worse battery life, hopefully this resolves that.
Same for me. I’ve also got my fingers crossed. I turned AOD back on and will give it a test run tomorrow.
