I Have a Apple Watch Series 1 2016 A1802 latest kind broken, what kind of replacement should i buy? do i buy a apple watch...

if you screen got broken inner, it will not waterproof. So you need go to a repair shop and fix your screen. since you are wondering after change a new screen will still waterproof, i think yes. for mostly screen repair, they will put a new iphone 7 plus waterproof sticker, so that your iphone will still "waterproof" . Maybe you can call a nearby repair shop and confirm with them.

normally only lcd assembly, not have anyone to sell only oled display .

you can bring to a repair shop and try series 1, i think it normally will be same, but can't make sure.

no, ipad mini 1/2 is same digitizer but ipad mini 3 and mini 4 is different, ipad mini 3 you can change a digitizer by yourself easily, ipad mini 4 you can't, you normally need a lcd digitizer assembly for ipad mini 4, only if you are a refurbished factory have special cut glass tools then you can change ipad mini 4 digitizer.

you can get a ipad pro screen replacement here. it is not easy to repair ipad pro digitizer only or change glass, it need special tools etc.

hi you can get a lcd screen and digitizer assembly here, very reasonable price

you can get a Sapphire apple watch Screen Replacement here

that long home flex is ok to be replaced, if you have original home button with home flex which sensor working before, after you replaced screen and long home flex, the touch id should be work.

long press, the message you want save, then it will show copy, copy and paste it to your phone memorandum, then all record you can save like this, normally what's app will save your message for a long time too, so you no need to worried.

Yes, it is different bezel. ATT is N990A verison, Tmobile is N900T.

this is very helpful
