My wife currently has a Moto E gen2. We’re looking at getting a moto E4 .
Regardless of what phone we do get will we be able to transfer app data from the old phone to the new phone. For example she has been playing a game called WordTrek for several years. Will we be able to transfer her history from that app to the new from home. That’s just one example.
Most app data is now being back up by Google play store [though it takes the developers to set it up to take advantage of this] I found this to be better my last phone upgrade [this year] than the last upgrade , best advice for data transfer is in this blog
I don’t exactly know what you mean by “app data”, but I’ll take a shot. My son is a gamer. When we bought a new phone for him he wanted some of his games to transfer over with the same saved progress he achieved on his old phone. This involved a lot of Google searching to determine what files I needed to grab from his old phone, and manually transferring these files to the new phone. There was not a one size fits all solution (every game app had it’s own specific file, or group of files, for saved game progress). There are likely some backup and restore apps that may be able to accomplish this more easily, but I don’t have any experience with them.
