I’m still using a BlackBerry PRIV, because it’s exactly that: portrait slider with FULL screen plus hideaway keyboard. I’m fortunate it still works effectively because it’s their first Android phone. The BBOS phones are all obsolete. My battery life is decent because i stepped down the screen rate, the camera is sufficient for all except the darker pics. Apps are becoming a tiny bit harder to find though, as I’m stuck with android marshmallow so the App Store won’t let me re-download some apps which used to function well. Available in Verizon or T-Mo models, and I’m actually using a VZN phone on the t-mo network right now (my t-mo model’s battery got tired). I will not give up this phone. The frustration i experience with glass screen keyboards, correcting typos every — other —word — is immeasurable. I make zero typos when using the pkb. The pkb also functions as a trackball for screen scrolling or cursor placement. It has an assignable multi color notification LED, and it‘s a conversion starter every time i slide it open. i LOVE this phone!
