Thanks
Thanks for trying to help the network with whatever you have. But I don't think there is any option to run a full node on your Android device. I guess there are enough nodes online at this moment. So, you don't have to run a node if you have any problems. But, if you can run a PC 24/7, or even less times, try to run a full node or a pruned node. It should depend on yourself.
You can even run a full node on a old device that you can buy spending $100. I guess there was thread by n0nce or someone else who shared how you can run a node under $100. You can search around if you really want to run a node.
