I was a long time Windows Phone user (I still do have my old one which I use on occasion). Overall the gains I get have made it so I will probably stay with Android for a while. I just don't know if Windows can catch up. Once you come over you realize how far behind they are.
Tips: Hope these help, I am still figuring things out.
1. Find a good Google now hands free launcher, even with the issues it is still needed.
2. Check out some of the apps for places you frequent (like restaurants). There are some sweet discounts there.
3. Until you really learn the system, don't mess too much with launchers, it will just muck up the learning process.
4. Be patient. The android OS while powerful has a real major learning curve requirement. In the ends the benefits outweigh the cons.
5. Do install the Office products it will help smooth the transition.
6. If you are on ATT use the contact mover tool. It works well.
7. Keep your old phone for text message reference and forward yourself text messages you need to keep.
8. It can sometimes be hard to get answers to issues (probably due to how large the community is), don't get frustrated, there can be resources out there to find them, and your friends may have answers. As I don't really know many people on Android (do to the area I work in), it has been a little more difficult).
The good:
1. When you search for an address or location, the information is reliable and accurate
2. The app store is easy to search and there is an app for just about anything and then some.
3. The modern Androids are responsive.
4. Fingerprint scanner unlock is nice.
5. Navigation apps are incredible.
6. Voice to text accuracy is pretty darn good. This exceeded my expectations.
The compromises (Things that I just expected to work that don't but I have learned to live with).
Note: A lot of these are WTFs and things I guess I expected as I assumed in general features that Android would be on par or better but was disappointed to find out it was not. This does not diminish my stand to stay with Android over Windows Phone, but just issues I would like to one day solve. As I learn how things work I may write tools to fix these.
1. Wifi is easy to setup but whatever I set as a favorite or "My connections" becomes disabled when I go out of range. This is a real pain but I have learned to live with it.
2. Voice (Hands free) does not work out of the box, you have to have an app, that connects. EG BT to GN for pressing a button to launch google now.
3. Finding names in the list of contacts, for some reason it has a hard time finding names, or it changes. I have not found a way to setup nicknames.
4. Battery life has been lower on the Android than on my 1520 Windows phone running Windows 10 10586.29, this is not the end of the world as it does last most of the day and is still good when I get home. Battery save does work well though when you get low.
5. There is a limit to what contacts you can link and for whatever reason Android has created a lot of duplicate variations for the numerous apps.
6. Apps do mess with your contacts. This is an annoyance but it does not seem to replace a contact, although it make replace the tag name.
7. Outlook Mail is really just OK, I do like the Windows Version better where you can pin folders that matter to your front screen and they update seperately. In the main mail app, it kind of merges stuff together and it can get hard to seperate stuff out, of if that new message is important. I am figuring it out slowly. In the meantime I do use my Windows Phone as a backup mail client. The other Office apps are pretty nice and work well, Windows 10s version seem to be similar for eveything but mail.
8. Contacts and calling can sometimes be a pain. Luckily in the LGV10 (what I got) you can pin contacts to the 2nd screen so I put important contacts there.
9. You can't make a call via Google now (using the BT to Gnow hands free app). when the phone is locked. So on the go hands free is almost useless for me. I have yet to find a solution.
10. When launching BT to Gnow to send a text message when the phone is locked, it will go through the process but will not actually send the message even though it said it did. WTF?
11. When in hands free using voice to text message, it will not read the message back to you before sending it or prompt you. I have not found a way to solve this so I just live with it.
The bad:
1. There really are not a lot of bad things. However I would consider the fact that sometimes Android is too open. Apps can affect apps.
