Help please. My phone is rooted and I deleted the standard samsung s4 keyboard and replaced it with swift key. I also deleted my files and replaced with file explorer. I did a factory reset of phone and now there is no keyboard to use. As no keyboard I can't get into playstore to download a keyboard and when I plug phone to my computer as I have no file explorer on the phone can't see the APk file I transfer so I can launch it. I'm not technical at all so any help so I can use the phone will be appreciated to get a keyboard APk back on my phone.
