Hi there,
My first experience with Android OS started from Motorola XT720. Motorola Milestone XT720 was shipped with Android version 2.1. It was slow phone with thoughtful web browser. First what I decided was to upgrade ROM. I found option to upgrade 2.1 to 2.2 from Cincinnati Bell - Motorola Milestone XT720 Upgrade with Flash 10.1 Support. But phone and web browser worked slow any way. I continued my investigations and at least I found new ROM CyanogenMod 7 on Android 2.3.7. Unfortunately it improved my phone no too much. And I decided to install another browser from the market. I tried Opera Mobile/Mini, Dolphin Browser HD/Mini, Boat Browser/Mini. Any of this browser didn't provide noticeable improvement. After searching internet I found Miren Browser. I read a lot of positive reviews about speed of this browser. And for sure I decided to try it. Unfortunately Miren Browser was unavailable in Android market. But I found apk file on another web-site. And this browser was really faster than another. I was glad to use on my Motorola XT720.
After about a year I changed my Motorola for HTC Amaze 4G from Wind Mobile(Canadian operator). It was a BIG difference. This phone is fast and everything work nice and smoothly. I migrated all my software from old Motorola on new HTC, and for sure Miren Browser. And as this phone is much faster I started to try different software include another web-browsers as example Firefox what isn't compatible with my previous Motorola XT720. I like Firefox – as I can synchronize my data with my desktop browser, and it has addon Adblock Plus for blocking Ads.
As I started to use Firefox on my HTC Amaze, and only sometimes I used it for comparing with Firefox on some websites. I almost forgot about Miren Browser. But for some reason I decided to check statistics of using internet traffic in my cellphone. As I have unlimited internet in my mobile plan I've never worried about usage, just I decided to check what program use traffic most of all. And what was my big surprise when I noticed – this program is Miren Browser, what I almost never use. And all this internet traffic usage was done in background, what is logically, as last time I started Miren Browser may be couple of month ago.
More then 100mb of internet traffic in background every month! For me Miren Browser is like malware or spam-bot or something else like this. I uninstalled Miren Browser immediately. And now I worry about my personal data, as Miren Browser had an acces to Storage, SD card.
Guys, put attention to software what you have on your phones.
