A lot of OutOfMemoryError from Samsung Galaxy devices on Android 7.x

Question

I have an active app on Google Play Store. Since a few months I'm getting a lot of weird crash reports on Play Console.

Since I can't paste all the data here (there are A LOT of crash reports) I'm trying to show a good summary. Detailed info on request.

Mostly affected devices:

Samsung Galaxy A5 2016 (a5xelte)
Samsung Galaxy S5 (klte)
Samsung Galaxy A5(2017) (a5y17lte)
Samsung Galaxy Note3 (hlte)
Samsung Galaxy S5 Neo (s5neolte)
Samsung Galaxy S6 (zeroflte)

ND: The first device is very critical compared to the others

Types of crashes:

java.lang.RuntimeException in android.app.ActivityThread.performLaunchActivity
java.lang.OutOfMemoryError in java.lang.StringFactory.newStringFromBytes
java.lang.OutOfMemoryError in libcore.util.CharsetUtils.toUtf8Bytes
java.lang.OutOfMemoryError in java.lang.StringFactory.newStringFromChars
java.lang.OutOfMemoryError in java.lang.StringBuilder.toString
java.lang.OutOfMemoryError in java.lang.StringFactory.newStringFromChars

Android versions: 7.0, 7.1 and rarely 6.0

I don't know why this is happening on these devices, I don't know how to debug these reports and I didn't find anything similar on StackOverflow or any other sources. Any help?

EDIT, some stacktraces:

EDIT 2: I updated the dependencies of firebase-ads but I'm having still the same crashes. Plus, I had a new crash type in this version:
