14 DAY TRIAL // Samsung hasn't yet managed to get back all the Galaxy Note 7 it sold during the last couple of months, but it's getting very close to the 100% goal. Around 2.5 million Galaxy Note 7 units were sold by the time Samsung announced the second recall, but most of them have already been returned.
In order to force too “loyal” customers to return their Galaxy Note 7 smartphones, Samsung announced that it would limit the battery charge to just 60%.
On top of that, Galaxy Note 7 units still in the hands of customers will receive messages and notifications that they must head over to the nearest Samsung store and ask for a replacement.
But here is something funny that happened to probably a dozen of people who own older Galaxy Note versions. The XDA forum has a few Galaxy Note 7 ROMs that you can flash on the Note 3 or Note 4, probably on the Note 5 too.
However, we don't advise doing that since your phone might have its battery limited or you might be invaded by Samsung's spammy messages telling you to go ahead and return your Galaxy Note 7, even though you have a Galaxy Note 3 running a different ROM.
This happened to Reddit user dominicedcel, who started to receive Galaxy Note 7 advisory messages urging him to back up data, power down and return the phone to the store or carrier where he bought it.
Also, flashing a Galaxy Note 7 ROM on an older Note model could also trick Samsung's servers into thinking that those smartphones haven't been returned even though they aren't Note 7 units.
Obviously, this makes it harder for Samsung to actually discern between the real Galaxy Note 7 units still in the wild and other Note models that are simply running Note 7 build.prop. Bottom line is, you shouldn't flash a Note 7 ROM on your smartphone, at least not yet.
