I had a similar issue with my Galaxy S4 a few years back, when I first started getting interested in repairs. I had accidentally snapped the head off the antenna so it obviously wasn’t connected. I only realized it when my signal was crap and I had to buy a new antenna. It may also be due to the charging port connector as Ian Shalongo said. Before you go ripping your phone apart though, you should try a few things… Try rebooting the phone. Check for any updates. Many Pixel 2 owners had signal problems that needed an update to be fixed. Try basic trouble shooting steps like popping the SIM out and back in, resetting network settings, etc. There is a really good guide for https://thedroidguy.com/2019/03/how-to-fix-a-google-pixel-2-with-poor-or-no-cellular-signal-troubleshooting-guide-1087616 Good luck and God Bless

Hit the power button! (Ha ha) Likely you need a new battery.

Likely, one or more are working in the background. Go to settings then battery and you should see what apps are used the most. Alternatively you can download many apps that help alert you to unnecessary background running.

iFixit has plenty of guides from fellow owners! DJI Mavic Pro Also, if DJI has a manual from the manufacturer it should be on the website

there is a feature that allows you to control your TV with the console. http://www.ign.com/wikis/xbox-one/How_to_Control_Your_TV_Volume_And_Po... This may be acting up. Try turning it off. If it still happens, it is either the TV, or the outlet.

It is most likely damaged. My Galaxy TAB did this. I don’t know if PS4 controllers themselves get updates but that might help.

Can you see the iPod through Windows Explorer or Finder? You might be able to just access it like a flashdrive. Programs like Houdini, AnyTrans, and iExplorer can also access the files. Apple tends to be stingy, and only allows transfur of music you bought on the iTunes Store, and won’t let you take non-Apple tracks off an iPod and add them to your Library for some reason. If you get the files on the PC just go to Add To Library and select the folder or file(s) and add them to the new PC’s Library.

Rogers will be shutting down their 2G towers in 2018, along with most of their 3G, in order to switch to VOLTE (Voice over LTE). While it is best to upgrade, I can relate, as I currently rock a BlackBerry, and am facing Verison's 2G shutdown in 2019. What you need to do is unlock your phone. You can contact the manufacturer, contact your provider, use Google to find if it has a generic code, or pay $20 online to get the code. Sadly, you can't upgrade your GSM phone to use CDMA or vice versa. Or upgrade from 2G to 3G. Otherwise, my BlackBerry would have LTE-A. What the manufacturer put in is what you are stuck with.

Is the button on screen? If not, is it clicky or digital?

I had a full sized SCH-I545 (S4). Either you tripped Knox and it won't let you update, or the Root you used disabled updates so you wouldn't brick your phone. What I did was I plugged it into my PC and used a ROM program to flash the stock rom back on. If that does not work, try using KIES (You might have to try 2 or 3 to see which works with your phone. Mine used KIES 2). It is the iTunes of SAMSUNG in a way.
