The Acer Liquid S1 Duo offers a 5.7 inch (14.47 cm) large HD display and thus belongs to the currently the trendy magnitude of dual SIM phablets. The resolution is 720 x 1280 pixels means a pixel density of 257 dpi in this screen diagonals.
For concentrated inspection although you can still recognize individual pixels, but we have the resolution - especially with moving images - felt in the mobile test as well. The screen can be thanks to IPS also read quite well from a steep angle, however, the image loses more color and saturation, as you would expect from IPS displays is used to.
Operating System and Processor
The Android version 4.2.2 is currently a newer OS version is currently installed in any mobile phone dual SIM. The powerful quad-core processor ensures together with the operating system for rapid reaction on display operations. Scroll, Scroll, Toggle between apps are also carried out very smoothly in all everyday tasks.
In addition to the normal Android system, the user interface UI float is still installed. This provides for example for multi-tasking "Float Apps": Here are four default apps at any time in parallel with the ongoing task called, namely camera, notes, cards and computers. Also a float UI component is the practical everyday voice control that lets you unlock the phone and certain features can control (camera).
There's a high resolution rear camera with 8 megapixels and full HD video recording and a front camera with 2 megapixels available. Well suited for video chats are the 88 ° wide angle. If necessary, also is a faster burst mode available, which records 16 frames per second. The image quality is acceptable for beautiful holiday memories one should rather carry a separate digital camera. The pictures are missing altogether somewhat sharpness and brightness.
manage 2 SIM cards in Acer Liquid S1
The management and selection of 2 SIM cards on the Android "Settings" menu easily accessible. For outgoing calls, SMS and mobile Internet can each preset a certain number or more ad hoc decide which SIM card is to be used. Contacts of the 2 SIM cards can be summarized by the way in the same phone book. Both lines are ready to receive the same, but can not be used for parallel calls or telephone conferences with two SIM cards.
Convenient: when a call on one of the two numbers is received, the app is not easily interrupted if you use just one. Rather, a small additional window appears on the screen, which provides several options: You can accept the call, reject it or send a message to the caller. This so-called float Caller proved over other models in the Dual-SIM Cell Test to be very practical.
Cloud services from Acer
A special feature of Acer provides its own office tools, which save up files and notes on Acer Cloud Docs and Acer Cloud Remote outside of the smartphone and can be retrieved from there. This saves space. Thanks to a wireless display technology can also content anzeigenm not only on the already quite large phablet monitor, but also convey fairly straightforward on another, larger screen.
In a pocket or jacket pocket, the dual-SIM phablet Acer Liquid S1 was transported well mostly in our test. The rounded corners help something that it is not "skewed" in spite of its length and width here. However, it does not disappear as inconspicuously in the pants, as you would expect from smaller smartphones. Not recommended, it is also for tight jeans or shirt pockets.
The frame around the display would have a total of - if you compare the model with other smartphones - may quietly be somewhat smaller. The weight of 195 grams you realize when using again not negative at, for its size had the Liquid S1 in the test even more easily.
The Acer Liquid S1 combines above-average hardware and latest software to a good overall package. It is a best buy, but not a bargain. Anyone looking for a very large smartphone with 2 SIM slots, not has currently also a lot of choices.
Something cheaper alternatives with only 5.0 "display are very good and favorable Huawei Ascend G700 (test) or the once-effective Samsung Grand Duos (Test) , which can, however, keep up technically not quite the Liquid S1. The even slightly larger Huawei Ascend Mate turn offers very similar performance standards as the Liquid S1, costs about the same, but can accommodate only a single SIM card.
