Installation Summary

FlexiSPY – A Spy Phone App That’s Easy To Install

When looking at Android spy apps, or any spy phone app for that matter, there are few key installation features that you should keep in mind: how easy is it to install, how long does it take to install, and will the spy phone app be hidden or invisible after it is installed.

FlexiSPY for Android has some technical aspects to its installation, but you are guided through the process and told where to go and what features you need to disable to get it working. You will need to have a rooted Android or jailbroken iPhone to access all of FlexiSPY’s features, as well as to run the monitoring software in invisible mode.

If you have an unrooted Android device or if your device does not allow you to hide the software completely, then FlexiSPY will be detected by antivirus software. However, we found that all Android spy apps we tested are detected by antivirus if the device is not fully rooted or not rooted at all.

It is important to note that not all Android devices, even when rooted, may be able to run all FlexiSPY's root features. Therefore, pay attention to the compatibility requirements of your mobile phone. Luckily FlexiSPY has a remote installation service that will tell you if your phone can be rooted, complete the rooting for you and install and activate the software. This means it will also be fully hidden and undetectable.

"FlexiSPY offers you the most features for your money, many of them exclusive.”

If you have a compatible rooted Android or iPhone device, then installation only takes around ten minutes in total to download, install and activate the software. This is faster than many of the spy apps we tested. Even if you install FlexiSPY on an unrooted device, you still get more features than the total number of combined features offered by other Android spy apps we reviewed.


FlexiSPY Delivers On Cell Phone Monitoring Features

FlexiSPY advertises more than 150 mobile spy features, which is more than any other spy phone app on the market. In addition to the sheer volume, FleixSPY also has many features you won't find anywhere else, like sending Spoof SMS, VoIP Call Recording and a keylogger.

For people who need to monitor chat applications, FlexiSPY is the best option. This spy phone app lets you track the most popular IMs, including WhatsApp, Facebook Messenger, Viber, LINE, Skype and many more. Unlike other Android spy apps, FlexiSPY captures the full contents of every conversation, not just the text. It also provides the contact details, date and time stamp, so you know exactly who is sending and receiving each message.

It is important to note that with frequent updates to chat applications, FlexiSPY and other monitoring software providers are not always able to keep up. For more details on this, FlexiSPY provides an updated list of the latest versions of its supported applications.

When we tested FlexiSPY Extreme on our rooted Android device we found that all basic and advanced features worked when we tested them. However, as technology varies by device it is important to remember to check the compatibility of your mobile phone to ensure you too can take advantage of every feature.  

“If you want the best in IM capturing or call recording, FlexiSPY is the clear leader.”

If your Android cannot be rooted, there are still a number of basic features that we found to work flawlessly and immediately after installation. These include the SMS tracker, call log capture, location monitoring and the keylogger. The keylogger feature works on unrooted and rooted Android devices, as well as iPhones. This feature allows you to record keystrokes that are typed into the phone, including deleted text. FlexiSPY’s keylogger does not capture encrypted passwords though.

Other features like Call recording, Spoof SMS and remote camera capture are available for Extreme subscription customers with both non-rooted and rooted phones and require some additional steps to set up. But exclusive features like these help make FlexiSPY the best spy phone app.

Our FlexiSPY reviews determined that this monitoring software is the best, because of its numerous features for rooted and non-rooted devices, high functionality and reliability. There are some features that require additional steps after the software is installed, but if you are willing to put in the additional effort then we think you too will see this as a top-of-the-line spy phone app.


FlexiSPY Is The Best Spy Phone App For Battery And Data Use

We tested FlexiSPY on an Android device and got just over seven hours of battery life when using the default setting which uploads data to the online portal as soon as it is captured. This is more than any other Android spy apps we have reviewed. We did, however, notice an increase in data usage on the device due to the call recording, ambient recording and remote camera features.

“FlexiSPY's the best Android monitoring software you can buy.”

Overall, we found that FlexiSPY’s monitoring software manages battery life and data usage more effectively than its competitors. We also found that other applications running in the background tended to have a greater impact on the device’s performance that this spy phone app.


Customer Support Is Excellent At FlexiSPY

FlexiSPY offers a wide range of support options, including presales, installation and technical support.

Presales: FlexiSPY has a 24/7 Live Chat feature on their website, as well as a 24/7 phone number (+1 213 810 3122) where you can speak to an agent about any questions you have before purchasing their spy phone app.

“FlexiSPY support staff always were quick to reply and solved our issues.”

Installation: FlexiSPY has a worry-free installation service for a fee of $39.99. For information on this service or to discuss installation questions, you can talk to an installation team member on Live Chat.

Technical: After you have purchased FlexiSPY, you have can seek technical support by email or through the FlexiSPY support ticket system. We think it would be better if this spy phone app had the same 24/7 Live Chat support as they do during presales, but we still found their support to be more responsive that other monitoring software providers (we received answers to our emails and tickets in less than 24 hours).

Our Conclusion

FlexiSPY is the best spy phone app on the market due to its long list of features, reliable performance and responsive customer service. There are a few things that can be improved, like no Live Chat after purchase and some technical set-up steps, but overall FlexiSPY is the most well-rounded of all the Android spy apps we reviewed. FlexiSPY has been in the monitoring software business since 2005, so we were more than comfortable investing in this premium product.
