Why not replace the 6S (whether is has a TSMC or Samsung chip or not) for the Galaxy S6? The S6 is the better phone of the two. Like seriously. I had the 6 until a couple of days ago and sold it for the S6. Never been happier with a phone!
The 6 and 6S have cameras that are pathetic in low / medium light, doesn't come close to the S6. They're comparable at speed and fluidity, you get a much better display with much higher resolution on the Galaxy, you have OIS on the S6 which the 6S lacks, you get 16GB on the base model which costs hundreds of dollars more than the 32GB Galaxy S6. All because of Apple wanting to milk out as much as money as possible from their customers, so they're cheaping out on stuff to produce it. Also you don't have to deal with iTunes for transferring songs. You can even play YouTube videos and send Whatsapp messages at the same time on the S6, or multitask with other apps like browser or email etc. at the same time with Multi Window.
Now that I left Apple I understand how strong the brand name is of Apple. They can give their customers the feeling that they're having the superior product, while in reality it's quite the opposite of that.
Meh. I really like android and it's great for a lot of things. But at least on the galaxy and htc ones I owned:
My battery started draining quickly at times
Phone got slower over time, was very fast at first
Ads in my notification bar occasionally, yikes!
Carrier branding and apps on my phone!!
Broke screen and had to ship it away and no phone for over a week!! Last time broke iPhone in and out of Apple Store in 30 min
Majority of family and friends on iPhone (imessage, FaceTime)
New versions of Android came out and I couldn't upgrade easily- upgrades had to be approved by carrier and manufacturer, if at all, months later
App quality lower than iOS
Resale value doesn't hold up compared to iPhone even if it's more expensive. Easier to sell as well. Sold my 6+ for $600, after the 6S was already out.
Anyway, like I said still really like androId and still have my htc one. Couldn't sell for enough to make it worth it. Love the customization and sharp screens of some of the flagships. But I want my phone to just work, well, out of the box. I flashed roms and customized in the honeymoon period with my android phones and after a while stopped and started just using my phone.
