Does instagram drops image quality?

I've been using instagram on iOS. I heard that instagram on android devices drops image quality badly but on iOS the things are not disastrous. Recently I've uploaded a photo through my iphone on instagram. I've found that the original file size was like 1.3mb. But the post processed file through instagram app is around 850kb. I've checked exif data of both the unprocessed and the processed files. It showed that both of the files contain same amount of pixels. But why the processed image file has a smaller size?! Does that mean it dropped the image quality?!

How much will it cost to repair a bent iPhone 6s?

It still works, but it's bent. It will probably need the digitizer, LCD, battery, and frame bent back into place, or replaced. How much do you think it will cost to get it repaired by professionals? (I know only a professional will really know I just want to know what others think)

Is a Verizon jet pack or mifi stronger than iPhone personal hotspot on Verizon?

I have Verizon, an iPhone 6s, our Wi-Fi went out, so we used my phone as a hotspot, I don't get good signal where I live and it was glitchy and barely worked, if I buy a Verizon jet pack Wi-Fi hotspot device (or similar) will it work better? What other option are there other than Verizon hotspot? Are any not connected to phone services?

Iphone 6 in washing machine screen unresponsive?

It got soaked, for about 3 minutes before i realized it was missing. Took it out, put it in rice, it turns on but the screen does not respond to touch. The screen never went black and its impossible to turn off without swiping the off thing. (I've tried holding down the home button and off button but its just a reset) anyway to shut it off without a reboot? And what should I do?
