Had other droids w/different mfg that utilized apps similar to this. The network booster worked far better than anything else I tried before. PROs - on this retread govt phone I can NOW readily get internet AND it doesn't suck up the battery like most other apps do. CONs - my ISP allows only 2GB per month. So this upgrade is bittersweet for me :(

My complaints are the damn ads. They cover information necessary to operate functions, and to view other DU stuff. I'd like to see a paid version available. There's inadequate instructions to operate well, and "app manager" doesn't manage, it just deletes apps. Useless. Shuts apps on the ignore list, haven't seen any on "white pages" yet.

I have been using du products for quite awhile. They work well but lots of ads get in the way and some are confusing. It takes a bit of careful tuning, but I put it on all my androids as STD equipment.

It is a recent install and I haven't made up my mind. I don't know if it really does what it says it does. I will find out. Then I will let you know. It has now been a couple of days. I still don't know if it is doing anything. It is as evasive as any piece of gear I've ever seen.

The app's Trash Cleaner cannot handle phones with no external SD card... And assumes that a phone must have one (not true with some phones with large internal storage). Therefore, the Trash Cleaner function doesn't work on such phones. Also, the app consumes a fair bit of data... The purpose of which is unknown. Why should a cleaner app need to send so much data back to a server?

This App has made a believer out of me after 5 weeks of rigorous testing. Effective and thorough in performance. I'm using three DU Apps with similar results. 5 star products. It's a refreshing find! Downloaded beginning of July 2016, to review and "never looked back", as they say. Updated: 9 Sept 16
