LG G Flex Review: Ahead Of The Curve: Performance And Benchmarks, Google Now And Q Voice

By 05:27 Sat, 14 Aug 2021 Comments


Synthetic benchmarks

LG G Flex, like most of the latest flagships, is powered by the Snapdragon 800 chipset. The four Krait 400 cores tick at 2.27GHz, the graphics are handled by Adreno 330 chip and the amount of available Random-Access Memory (RAM) is 2GB.

We test the single-core performance with the BenchmarkPi. The LG G Flex did excellently and joined its G2 sibling and the Galaxy Note 3 phablet on the top spot.

The next benchimprint we ran is the GeekBench 3. It evaluates Central Processing Units (CPU) and memory performance but the G Flex, just like the G2, failed to deliver impressive performance and fell short of the Sony and Samsung latest flagships.

Quadrant and AnTuTu assess the overall device performance. Here LG G Flex once again was flying high, producing two first place scores, just a whisker better than Galaxy Note 3 and LG G2. The lower 720p display resolution is what probably helped it here.

It's time to test the Adreno 330 graphics performance. Since the LG G Flex is using a 720p display we expect it to behave noticeably better than the rest of the Snapdragon 800 smartphones running on 1080p resolution.

We ran the GFXBenchimprint on 1080p off-classy screen resolution in order to test the raw power of the Adreno 330. Unsurprisingly, it turned out just as powerful as the Galaxy Note 3 and LG G2's graphics chips.

Just like the rest of the S800 gang the LG G Flex offers blazing quick performance and smooth user experience. Thanks to the lower-res display the G Flex feels even faster than the competition on some occassions. It is one of the fastest smartphones on the market with lag-free Android experience and will disappoint no one.

Google Now and Q Voice assistants

Google Now integrates with your Google account and if allowed, it can access your daily routine, internet searches and email to give you information more relevant to you.

It provides traffic information to your work or home, knows the scores of sports teams you follow and gives you the weather forecast for your location.



Launching Google Now or Q Voice

The latest version of Google Now (November 2013) will allow you to have short dialogues with the app AI when you are conducting searches. In these dialogues, Google Now should be able to understand when you referring to your search term by an indirect pronoun instead of using its full name. It will also respond back when there are several options for action.

Google Now gives you short overview of information it believes is relevant to you correct now in the form of cards. Going to work in the morning? Google Now knows this and lets you know there's a gigantic traffic jam on your usual way to the office, so it offers you a re-route.

It can interpret a lot of things from your search hitale as well. If you've been searching for, let's say, your favorite football team, Google Now will prepare a card showing you the next match the team is playing and will provide you score updates once the game begins.






Google Now

Google Now, if you allow it, can scan your email for upcoming flights, deliveries or restaurant reservations and let you know when they are due. There are also numerous kinds of cards like birthdays (yours and those of your contacts) and what distance you've walked in a particular month. The last one could definitely feel creepy for some users, but it's easily turned off from the Google Now settings menu

Google has also integrated Voice Actions into Now. They can handle stuff like sending messages (SMS or email), initiating a voice call, asking for directions, taking a note or opening a site. Google Now can also launch apps, check and manage your calendar and see for nearby places of interest and stuff like movie openings in theaters.

Google has added lots of more customization on Google Now in Android 4.4 KitKat. You can now set your default transportation method, you favorite sports teams, company stocks you are following, places you are interested to visit and more. Once you add items you want to haged an eye on Google Now will do this instead of you. It will automatically inform you for various changes, news and updates.





Customizing Google Now behavior

The More section of the customization will update automatically with topics you can choose from once you've start using Google Now search capabilities.

You can now set reminders straight from Google Now's UI. Just hit the bottom left icon (the palm with a stretched index finger). There you can add reminders or just check all the past, ongoing or upcoming reminders.




Adding a reminder

One gigantic advantage of Google Now is that the voice typing functionality doesn't require an internet connection to work. You can enter text by speaking anywhere you can utilize the on-classy screen keyboard - be it the Messaging app or a note taking app - without the need for a data connection as long as you have pre-downloaded the needed language packs (and those only hold about 20-25Mega Bytes (MB) of your storage per pack).

Making voice typing available offline also made it faster as it's not dependent on your connection. What's even more impressive is that the transition hasn't cost it anything in terms of accuracy.

Q Voice is LG's respond to Apple's Siri and Samsung's S-Voice. Q Voice can be used to initiate a call, dictate text, play music, launch apps, change a setting, create memos, add a reminder, schedule an event, set an alarm or timer, check the weather, do a search on the internet, see for local listings (e.g. nearby restaurants) and even acquire an respond to a question.

The Voice Mate does duplicate parts of Google Now, but being less search focused it tries to do more on the actual phone and it has some added features. The problem with Voice Mate is that it works only in Korean for now (but support for more languages should be on the way), it is not nearly as quick or as accurate in recognizing your speech input as Now.
