Ok, active usage on TW Mobile (big brother big) 4G for last 4 days..network speed was EXCELLENT.
Using for business WA/IG/FB/GoogleMaps/TW traffic warning.
With these many apps open, it does lag when switching to a new app. IF using just one or 2 apps..smooth like butter.
GoogleMaps+TW traffic warrning app is a winner. Check it out using the M7 with app for HUD for speedometer, distance to speed camera and audio warnings.
Oh, for IFE usage...it was good. Widevine L1, so u get full HD with Netflix etc. Screen quality was good.
In short, manage expectations, as a backup/navi/media consumption phone...its a winner at $138 for 256GB/8 budget phone with a long EOL.
Oh..and the 7000mh battery..spectacular. Can go for 2 days without charging.
