How to get the adhesive tape to stick good after screen replacement?

I use original adhesive tape to connect the screen and backside. But everytime I fix a phone it does not stick good enough. I use clamps for 12 hours to get good pressure and also use a heatgun to heat it up before I put the clamps on. Still I have many customers complaining about the sceeen or backside coming off. So I end up using glue. Any suggestions on how to get the adhesive tape to stick good?

Amazon fire TV / stick

Hello, I'm struggling to find much info but I'm trying to figure out if this is the right forum for Amazon fire TV stick, I'm seeing lots of stuff for Amazon fire TV but is this the exact same as fire TV stick?
I'm basically wanting to have my fire TV stick setup with something like Nova launcher and install a TV app for watching TV and also a few other apps for TV shows ect.
Any info would be gratefully received and if I'm in the wrong place I apologise but if you could point me into the correct place that would be great.
Thanks

Thinking of getting Fire TV Stick

Stationed overseas, looking at buying a FireTV Stick to run Kodi and other apps on it.

What are the pro's and con's of it?
What apps should I install on it?
I have a ton of movies/tv shows, could I stream from my iMac to it? (This isn't needed to much)

I've had Kodi before on my devices, so figured a FireTV Stick would be a cheap alternative to have it on my Sharp Smart TV.
