Thanks.
The app that will require 6.0.2 is used for authentication for something. It looks like I'll now have to receive phone calls instead of push notifications.
Going forward, if I don't want the phone calls, my options are to either replace my phone, or get another compatible device such as a tablet.
I haven't liked some of the design changes with the newer Galaxy Notes:
* Phone is bigger. I don't want a bigger nor smaller phone. This is the right size. This is just about pocketable. Any bigger, and it would be even harder to fit in a pocket, along with other items.
* No more removable battery. I've never had a Galaxy Note 4 battery last more than 12-15 months. At that point, the charge capacity is reduced a lot. It's been easy for me just to buy another battery. If I get phone that doesn't have a removable battery, and the battery life ends up being about the same, I'll have to take it to a repair shop for a battery change, and that's a bigger hassle.
* Fingerprint sensor on rear. To me, I haven't tried a phone with a rear fingerprint sensor, but it seems harder to use, and more error prone. More likely that I wouldn't hit the sensor in the right way.
It seems faster and easier to use, when it's on the front.
Do I have any other phone options? I like the pen with this phone, when I use it, it works well. The other phones with stylus add ons don't seem as good.
I'm not sure of any other phone that meets these requirements.
I suppose I could get a Galaxy Note 5, since that supports the OS that I need.
Other options I see are a Galaxy Flip and Galaxy Fold. The Flip seems cool. Has a side fingerprint sensor, which seems easier to use than a back one.
And the fact that it flips, makes it more pocketable.
But the Flip doesn't come with a built in stylus? Neither does the Fold.
The on screen fingerprint sensor of the Note 10 seems pretty cool, and that it looks like it would work well.
I see the Note 10 regular version finally has a size that's not bigger, it's more comparable to my Note 4. So the phone size would be similar and not too big; and the fingerprint sensor seems about as easy to use as a note 4. The only other point would be the battery, not being removeable, when compared to the Note 4.
I could also just get a tablet which supports the OS that I need. That would be easier, and not involve the data transfer from a Note 4 to a Note 10. It would also be a lot cheaper, I could get a full HD tablet for a little over $200, compared to $730 for a Galaxy Note 10 regular phone.
Are there any issues with transferring text messages and stuff to a Note 10? I use SMS Backup and Restore to back up my text messages.
