So I don't know much about electronics, but my husband is so kind to come to all of my barrel races and video from his phone, but once he sends them to me or someone else they are SO grainy you can't see anything. I have seen some people at the races with a tablet. I don't want to spend $500 on an IPAD, so are there "generic" tablets that don't require to me to go through my cell phone carrier, that just work through wifi? I really just want it to video barrel races! 

Yes, he could use my phone, but he videos my friends too, and he can't hold 10 phones..

I think I've heard the Kindles record video but I don't know about the quality of the video. 

I have a Kindle Fire and have recorded rodeo/cuttings/playdays.   I feel like the videos are fine . 

Have you sent them to people?

Try having him send them via FB messager.

I have a friend with an Android.  I have an IPhone.  Any video she’s texts me sucks.  When she sends them in FB messenger they are fine.

Technology has outpaced my ability to keep up so I won’t claim to know why.  I’ve alao had issues with my SIL sending videos iPhone to iPhone...I think that issue is poor cell service usually.

He doesn’t have FB....

No I haven't, and that could make a difference in quality. . . 

Android to iphone is definitely a problem.  I changed to iphone because the rest of my family had them.  My new iphone takes great video.  And the option to Air Drop them to other peoples phones is wonderful.

I have an Iphone 8 plus, and I have a Samsung Galaxy Tab A tablet. I've tried taking videos/pictures off my tablet, and to be honest they come out looking terrible. You can find a used Ipad in good condition on ebay, honestly...I would go with an Ipad. The only reason I have a galaxy tablet is because I qualified for it free through sprint, and I just pay the $25 per month for unlimited data on it to watch movies and read my nursing books on for school.
